在iOS开发中不可避免的会用到一些第三方类库,它们提供了很多实用的功能,使我们的开发变得更有效率;同时,也可以从它们的源代码中学习到很多有用的东西。

Reachability 检测网络连接

用来检查网络连接是否可用:包括WIFI和WWAN(3G/EDGE/CDMA等)两种工作模式。

可以从Apple网站下载到:http://developer.apple.com/library/ios/#samplecode/Reachability/History/History.html#//apple_ref/doc/uid/DTS40007324-RevisionHistory-DontLinkElementID_1。

现在有更好的替代品:https://github.com/tonymillion/Reachability,比Apple提供的兼容性更好,而且更加好用,更具体的使用方法请看它提供的例子。

Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];reach.reachableBlock = ^(Reachability*reach) {    NSLog(@"网络可用!");};reach.unreachableBlock = ^(Reachability*reach) {    NSLog(@"网络不可用!");};// 开始监听[reach startNotifier];

 

ASIHTTPRequest 网络请求

ASIHTTPRequest是对CFNetwork API的一个包装,它提供了一套更加简洁的API,使用起来也更加简单。

官方网站:http://allseeing-i.com/ASIHTTPRequest/

GitHub:https://github.com/pokeb/asi-http-request

它不仅仅支持基本的HTTP请求,而且支持基于REST的服务(GET/POST/PUT/DELETE)。

最让人喜欢的是,它支持block语法:

   NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];   __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];   [request setCompletionBlock:^{      // Use when fetching text data      NSString *responseString = [request responseString];       // Use when fetching binary data      NSData *responseData = [request responseData];   }];   [request setFailedBlock:^{      NSError *error = [request error];   }];   [request startAsynchronous];

它的ASIFormDataRequest子类可以横容易的提交表单数据和文件:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];[request setPostValue:@"Ben" forKey:@"first_name"];[request setPostValue:@"Copsey" forKey:@"last_name"];// Upload a file on disk[request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"forKey:@"photo"]; // Upload an NSData instance[request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];

详细的使用方法请下载相应的源代码及例子,或者从官方的使用说明http://allseeing-i.com/ASIHTTPRequest/How-to-use开始。

 

MBProgressHUD 提示效果

支持各种状态加载的提示效果,以及带进度的提示效果。

GitHub:https://github.com/matej/MBProgressHUD

一般会在.m文件实现MBProgressHUDDelegate协议,并声明HUD变量:

@interface SampleViewController (){    MBProgressHUD *HUD;}#pragma mark -#pragma mark MBProgressHUDDelegate methods- (void)hudWasHidden:(MBProgressHUD *)hud {	// Remove HUD from screen when the HUD was hidded	[HUD removeFromSuperview];	HUD = nil;}

在执行某个异步请求时开始调用:

    HUD = [MBProgressHUD showHUDAddedTo:self.webView animated:YES];    HUD.labelText = @"正在请求...";    // mode参数可以控制显示的模式    //HUD.mode = MBProgressHUDModeText;    HUD.delegate = self;

请求完成时隐藏提示效果:

[HUD hide:YES];

对于同步方法一般都是用showWhileExecuting方法,方法执行完成之后会自动隐藏提示效果:

[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];

 

SVProgressHUD 提示效果

GitHub:https://github.com/samvermette/SVProgressHUD

SVProgressHUD和MBProgressHUD效果差不多,不过不需要使用协议,同时也不需要声明实例。

直接通过类方法进行调用即可:

[SVProgressHUD method]

可以使用以下方法来显示状态:

+ (void)show;+ (void)showWithMaskType:(SVProgressHUDMaskType)maskType;+ (void)showWithStatus:(NSString*)string;+ (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;

如果需要明确的进度,则使用以下方法:

+ (void)showProgress:(CGFloat)progress;+ (void)showProgress:(CGFloat)progress status:(NSString*)status;+ (void)showProgress:(CGFloat)progress status:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;

通过dismiss方法来隐藏提示:

+ (void)dismiss;

另外提供了以下方法用于显示状态,并在1秒后自动隐藏提示(使用的图标来源于Glyphish:http://www.glyphish.com/):

+ (void)showSuccessWithStatus:(NSString*)string;+ (void)showErrorWithStatus:(NSString *)string;+ (void)showImage:(UIImage*)image status:(NSString*)string; // use 28x28 white pngs

 

ZAActivityBar 提示效果

GitHub:https://github.com/zacaltman/ZAActivityBar

ZAActivityBar和SVProgressHUD非常相似,它提供了更加简洁的API来显示提示效果。

ZAActivityBar使用的动画效果来源于ZKBounceAnimation(https://github.com/khanlou/SKBounceAnimation),成功、失败的状态图标来源于Pictos(http://pictos.cc/)。

显示加载状态:

[ZAActivityBar showWithStatus:@"加载中..."];

显示成功、失败状态:

[ZAActivityBar showSuccessWithStatus:@"成功!"];[ZAActivityBar showErrorWithStatus:@"失败!"];

隐藏提示:

[ZAActivityBar dismiss];

 

SBJson JSON解析

官方: http://sbjson.org/

GitHub:https://github.com/stig/json-framework

API使用起来稍显繁琐,特别是初始化的时候:

@interface TestViewController () {    SBJsonStreamParser *parser;    SBJsonStreamParserAdapter *adapter;}// 冗长的初始化方法足以吓到一大片人- (void)initSBJSON{    // We don't want *all* the individual messages from the	// SBJsonStreamParser, just the top-level objects. The stream	// parser adapter exists for this purpose.	adapter = [[SBJsonStreamParserAdapter alloc] init];		// Set ourselves as the delegate, so we receive the messages	// from the adapter.	adapter.delegate = self;		// Create a new stream parser..	parser = [[SBJsonStreamParser alloc] init];		// .. and set our adapter as its delegate.	parser.delegate = adapter;		// Normally it's an error if JSON is followed by anything but	// whitespace. Setting this means that the parser will be	// expecting the stream to contain multiple whitespace-separated	// JSON documents.	parser.supportMultipleDocuments = YES;}#pragma mark SBJsonStreamParserAdapterDelegate methods- (void)parser:(SBJsonStreamParser *)parser foundArray:(NSArray *)array {    [NSException raise:@"unexpected" format:@"Should not get here"];}- (void)parser:(SBJsonStreamParser *)parser foundObject:(NSDictionary *)dict {    NSLog(@"SBJson parser foundObject");    // 处理返回的数据}// 使用ASIHTTPRequest请求测试- (void) loadData {    __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];    [request setRequestMethod:@"POST"];    [request setCompletionBlock:^{        // Use when fetching text data        //NSString *responseString = [request responseString];        // Use when fetching binary data        NSData *responseData = [request responseData];        NSLog(@"Connection didReceiveData of length: %u", responseData.length);                // Parse the new chunk of data. The parser will append it to        // its internal buffer, then parse from where it left off in        // the last chunk.        SBJsonStreamParserStatus status = [parser parse:responseData];                if (status == SBJsonStreamParserError) {            NSLog(@"Parser error: %@", parser.error);        } else if (status == SBJsonStreamParserWaitingForData) {            NSLog(@"Parser waiting for more data");        }    }];    [request setFailedBlock:^{        NSError *error = [request error];        NSLog(@"failed - %@ %@", [error localizedDescription], error);    }];    [request startAsynchronous];}

 

JSONKit JSON解析

GitHub:https://github.com/johnezang/JSONKit

提供比SBJson更优异的性能以及更加简便的使用方法,但是中文最好使用utf-8格式(/uXXXX),否则容易造成乱码。

API调用起来非常简单,省去了SBJson那么一大堆的方法:

JSONDecoder* decoder = [[JSONDecoder alloc] initWithParseOptions:JKParseOptionNone];id result = [decoder objectWithData:jsonData];

详细的使用方法请看它的GitHub主页。

 

SDWebImage 图片异步加载及缓存

SDWebImage用于异步下载网络上的图片,并支持对图片的缓存等。

多数情况下是使用UIImageView+WebCache为UIImageView异步加载图片:

#import // ...[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]                   placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

需要注意的是,pladeholderImage的大小一定要大于UIImageView的大小,否则可能不显示placeholderImage图片。

它还支持block语法用于在加载完成时做一些操作:

[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]               placeholderImage:[UIImage imageNamed:@"placeholder.png"]                      completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {... completion code here ...}];

SDWebImage并不局限于UIImageView上,使用SDWebImageManager完成更多的操作:

SDWebImageManager *manager = [SDWebImageManager sharedManager];[manager downloadWithURL:imageURL                 options:0                 progress:^(NSUInteger receivedSize, long long expectedSize)                 {                     // 下载进度                 }                 completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType)                 {                     if (image)                     {                         // 下载完成                     }                 }];

或者使用Image Downloader也是一样的效果:

[SDWebImageDownloader.sharedDownloader downloadImageWithURL:imageURL        options:0       progress:^(NSUInteger receivedSize, long long expectedSize)       {           // 进度       }       completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished)       {           if (image && finished)           {               // 下载完成           }       }];

 

UIActivityIndicator-for-SDWebImage 为SDWebImage显示加载效果

GitHub:https://github.com/JJSaccolo/UIActivityIndicator-for-SDWebImage

用于为SDWebImage在UIImageView加载图片时,显示加载效果(UIActivityIndicatorView实现),它提供以下方法:

- (void)setImageWithURL:(NSURL *)url usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;

 

UIImage+Resize 调整图片大小

GitHub:https://github.com/coryalder/UIImage_Resize

提供多种方法为图片设置透明度、圆角、裁剪、调整大小等:

- (UIImage *)imageWithAlpha;- (UIImage *)transparentBorderImage:(NSUInteger)borderSize;- (UIImage *)roundedCornerImage:(NSInteger)cornerSize borderSize:(NSInteger)borderSize;- (UIImage *)croppedImage:(CGRect)bounds;- (UIImage *)thumbnailImage:(NSInteger)thumbnailSize          transparentBorder:(NSUInteger)borderSize               cornerRadius:(NSUInteger)cornerRadius       interpolationQuality:(CGInterpolationQuality)quality;- (UIImage *)resizedImage:(CGSize)newSize     interpolationQuality:(CGInterpolationQuality)quality;- (UIImage *)  resizedImageWithContentMode:(UIViewContentMode)contentMode                       bounds:(CGSize)bounds         interpolationQuality:(CGInterpolationQuality)quality;

更详细使用见:http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/

 

ImageCacheResize 异步加载图片、缓存及调整大小

GitHub:https://github.com/toptierlabs/ImageCacheResize

整合了SDWebImage和UIImage+Resize的功能,用于图片的异步加载、缓存、以及下载完成后调整大小并显示在UIImageView上。

提供了以下API用于加载图片以及加载完成后调整图片大小:

- (void)setImageWithURL:(NSURL *)url andCropToBounds:(CGRect)bounds;- (void)setImageWithURL:(NSURL *)url andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder andCropToBounds:(CGRect)bounds;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andCropToBounds:(CGRect)bounds;

使用方法和SDWebImage一样简单,如以下官方例子:

[imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andResize:CGSizeMake(30, 30) withContentMode:UIViewContentModeScaleAspectFit]; // 按比例缩放[imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andCropToBounds:CGRectMake(0, 0, 100, 100)]; // 裁剪成100x100大小

 

EGOTableViewPullRefresh  下拉刷新

GitHub:https://github.com/enormego/EGOTableViewPullRefresh

这是最早出现的为UITableView提供下拉刷新功能的类库,使用起来稍显麻烦,需要实现诸多协议(代码取自官方DEMO):

#import "EGORefreshTableHeaderView.h"@interface RootViewController : UITableViewController  {	EGORefreshTableHeaderView *_refreshHeaderView;	//  是否正在加载中 	BOOL _reloading;}- (void)viewDidLoad {    [super viewDidLoad];    	if (_refreshHeaderView == nil) {		EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.view.frame.size.width, self.tableView.bounds.size.height)];		view.delegate = self;		[self.tableView addSubview:view];		_refreshHeaderView = view;		[view release];	}	//  更新最后加载时间	[_refreshHeaderView refreshLastUpdatedDate];}#pragma mark -#pragma mark Data Source Loading / Reloading Methods- (void)reloadTableViewDataSource{	//  在这里加入代码用于获取数据	_reloading = YES;}- (void)doneLoadingTableViewData{	//  数据加载完成时调用这个方法	_reloading = NO;	[_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];}#pragma mark -#pragma mark UIScrollViewDelegate Methods- (void)scrollViewDidScroll:(UIScrollView *)scrollView{		[_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];}- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{	[_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];}#pragma mark -#pragma mark EGORefreshTableHeaderDelegate Methods- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{	[self reloadTableViewDataSource];	[self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0];}- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{	return _reloading; // should return if data source model is reloading}- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{	return [NSDate date]; // should return date data source was last changed}

STableViewController  下拉刷新、上拉加载更多

GitHub:https://github.com/shiki/STableViewController

STableViewController比PullToRefresh多了一个上拉加载更多功能,使用上也差不多简单,需要继承自STableViewController,再实现一些方法:

- (void) viewDidLoad{  [super viewDidLoad];    self.title = @"STableViewController Demo";  [self.tableView setBackgroundColor:[UIColor lightGrayColor]];    // 需要创建两个自定义视图用于显示"下拉刷新"、"上拉加载更多"  self.headerView = headerView;    self.footerView = footerView;  }#pragma mark - Pull to Refresh- (void) pinHeaderView{  [super pinHeaderView];    // 下拉刷新视图显示一些加载动画}- (void) unpinHeaderView{  [super unpinHeaderView];    // 下拉刷新视图停止动画}- (void) headerViewDidScroll:(BOOL)willRefreshOnRelease scrollView:(UIScrollView *)scrollView{  // 下拉刷新视图显示状态信息  if (willRefreshOnRelease)    //hv.title.text = @"松开后刷新...";  else    //hv.title.text = @"下拉刷新...";}- (BOOL) refresh{  if (![super refresh])    return NO;    // 下拉刷新加载数据  [self performSelector:@selector(addItemsOnTop) withObject:nil afterDelay:2.0];  return YES;}#pragma mark - Load More- (void) willBeginLoadingMore{  // 上拉加载更多视图加载动画}- (void) loadMoreCompleted{  [super loadMoreCompleted];  // 上拉加载更多视图停止动画    if (!self.canLoadMore) {    //没有更多数据的时候执行代码...  }}- (BOOL) loadMore{  if (![super loadMore])    return NO;    // 上拉加载更多数据  [self performSelector:@selector(addItemsOnBottom) withObject:nil afterDelay:2.0];  return YES;}// - (void) addItemsOnTop{  // 加载数据...    [self.tableView reloadData];    // 数据加载完成通知上拉视图  [self refreshCompleted];}- (void) addItemsOnBottom{  // 加载更多数据...  [self.tableView reloadData];    // 通过判断设置是否可以加载更多  //self.canLoadMore = NO;    // 数据加载完成通知下拉视图  [self loadMoreCompleted];}

 

SVPullToRefresh 下拉刷新、上拉加载更多

GitHub:https://github.com/samvermette/SVPullToRefresh

包含SVPullToRefresh + SVInfiniteScrolling为UITableView提供下拉刷新、上拉加载更多功能。

使用起来也相当简单,只要在UITableViewController里实现以下方法:

- (void)viewDidLoad {    [super viewDidLoad];    __weak SVViewController *weakSelf = self;        // 设置下拉刷新    [self.tableView addPullToRefreshWithActionHandler:^{        [weakSelf insertRowAtTop];    }];            // 设置上拉加载更多    [self.tableView addInfiniteScrollingWithActionHandler:^{        [weakSelf insertRowAtBottom];    }];}- (void)viewDidAppear:(BOOL)animated {    [tableView triggerPullToRefresh];}- (void)insertRowAtTop {    // 获取数据....        // 停止动画    [self.tableView.pullToRefreshView stopAnimating];}- (void)insertRowAtBottom {    // 获取数据....        // 停止动画    [weakSelf.tableView.infiniteScrollingView stopAnimating];}
