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。
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
__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:
1
2
3
4
5
6
7
8
|
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:
1
2
3
4
5
6
7
8
9
10
11
12
|
@interface SampleViewController ()<MBProgressHUDDelegate>
{
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:
1
2
3
4
5
|
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:
1
|
[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:
1
|
[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:
1
|
[SVProgressHUD method]
|
可以使用以下方法来显示状态:
1
2
3
4
|
+ (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:
1
2
3
|
+ (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:
1
|
+ (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/):
1
2
3
|
+ (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:
1
|
[ZAActivityBar showWithStatus:@"加载中..."];
|
显示成功、失败状态:
1
2
|
[ZAActivityBar showSuccessWithStatus:@"成功!"];
[ZAActivityBar showErrorWithStatus:@"失败!"];
|
隐藏提示:
1
|
[ZAActivityBar dismiss];
|

@interface TestViewController ()<SBJsonStreamParserAdapterDelegate> {
SBJsonStreamParser *parser;
SBJsonStreamParserAdapter *adapter;
}
// 冗长的初始化方法足以吓到一大片人

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

// JSON documents.
parser.supportMultipleDocuments = YES;
}
#pragma mark SBJsonStreamParserAdapterDelegate methods
- (void)parser:(SBJsonStreamParser *)parser foundArray:(NSArray *)array {
[NSExceptionraise:@"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:
1
2
|
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:
1
2
3
4
|
#import <SDWebImage/UIImageView+WebCache.h>
// ...
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:
1
2
3
|
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
[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:
1
2
3
4
5
6
7
|
- (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;

|
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:
1
2
3
4
5
6
|
- (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:
1
2
|
[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
