UIActivityViewController|自定义share按钮

上一个demo:http://pan.baidu.com/s/1c0ANO6O

UIActivityViewController是IOS6.0以后苹果带的分享功能的视图控制器,属于uiviewController。现在一般都用umeng或者shareSDK,这个是原生版的。

创建UIActivityViewController的时候,苹果会自带几个分享功能,例如打印,AirDrop,save,Email等等。通过点击屏幕按钮,创建一个UIActivityViewController:



#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

UIButton *bt = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];

bt.backgroundColor = [UIColor orangeColor];

bt.layer.cornerRadius = 50;

[self.view addSubview:bt];

[bt setTitle:@"分享" forState:UIControlStateNormal];

bt.center = CGPointMake(self.view.bounds.size.width / 2, self.view.bounds.size.height / 2);

[bt addTarget:self action:@selector(share:) forControlEvents:UIControlEventTouchUpInside];

// Do any additional setup after loading the view, typically from a nib.

}

-(void)share:(id)sender

{

//要分享的内容,加要一个数组里边,初始化UIActivityViewController

NSString *textToShare = @"要分享内容title";

NSString *description = @"这是我的内容---------";

UIImage *imageToShare = [UIImage imageNamed:@"logocc.png"];

NSURL *urlToShare = [NSURL URLWithString:@"http://www.iashes.com/"];

NSArray *activityItems = @[textToShare, description,imageToShare, urlToShare];

//创建自定义的Activity,加到一个数组里边

MyActivity *act1 = [[MyActivity alloc]initWithImage:[UIImage imageNamed:@"logocc.png"] atURL:@"http://www.iashes.com/" atTitle:@"share Sina" atShareContentArray:activityItems];

//myActivity是自定义的类,继承于UIActivity

MyActivity *act2 = [[MyActivity alloc]initWithImage:[UIImage imageNamed:@"logo_64.png"] atURL:@"http://www.iashes.com/admin.html" atTitle:@"share Renren" atShareContentArray:activityItems];

NSArray *apps = @[act1,act2];

//创建

UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:apps];

//关闭系统的一些分享

activityVC.excludedActivityTypes = @[UIActivityTypePostToTwitter,

UIActivityTypeMessage,

UIActivityTypePrint,

UIActivityTypeCopyToPasteboard,

UIActivityTypeAssignToContact,

UIActivityTypeSaveToCameraRoll,

UIActivityTypeAddToReadingList,

UIActivityTypePostToFlickr,

UIActivityTypePostToVimeo,

UIActivityTypePostToTencentWeibo,

UIActivityTypeAirDrop];

//模态

[self presentViewController:activityVC animated:YES completion:nil];


MyActivity.h中:

#import@interface MyActivity : UIActivity

//title是当前类型,shareImage是分享图标,URL是要分享的地址,getShareArray保存用户要分享的内容

@property (nonatomic,strong) UIImage *shareImage;

@property (nonatomic,copy)NSString *URL;

@property (nonatomic,copy)NSString *title;

@property (nonatomic,strong)NSArray *getShareArray;

-(instancetype)initWithImage:(UIImage *)shareImage atURL:(NSString *)URL atTitle:(NSString *)title atShareContentArray:(NSArray *)shareContentArray;

@end


MyActivity.m中:

#import "MyActivity.h"

@implementation MyActivity

//初始化方法

-(instancetype)initWithImage:(UIImage *)shareImage atURL:(NSString *)URL atTitle:(NSString *)title atShareContentArray:(NSArray *)shareContentArray

{

if(self = [super init]){

_shareImage = shareImage;

_URL = URL;

_title = title;

_getShareArray = [[NSArray alloc]initWithArray:shareContentArray];

}

return self;

}

//以下方法都是自定义UiActivity需要重写的方法

+(UIActivityCategory)activityCategory

{

return UIActivityCategoryShare;

}

//设置类型

-(NSString *)activityType

{

return _title;

}

//设置现实的标题

-(NSString *)activityTitle

{

return _title;

}

//图片

-(UIImage *)activityImage

{

return _shareImage;

}

//返回yes就行,这个表示该分享是不是在controller中显示

-(BOOL)canPerformWithActivityItems:(NSArray *)activityItems

{

return YES;

}

//是不是自定义的controller,如果为空,则调用performActivity方法

- (UIViewController *)activityViewController

{

return nil;

}

//点击分享图标之后触发的方法

-(void)performActivity

{

if(nil == _title) {

return;

}

NSLog(@"要分享的内容-----%@",_getShareArray);

NSLog(@"分享的类型------ %@",_title);

if([_title isEqualToString:@"share Renren"]){

NSLog(@"---^^^  renren");

//调用人人的sdk

}else if([_title isEqualToString:@"share Sina"]){

//调用新浪sdk

}

}

@end
