首先导入系统类库

social.framework

导入头文件：

#import <Social/social.h>

之后使用UIActivityViewController显示分享选项，代码如下: (增加微信分享)

NSArray*activity = @[[[WeixinSessionActivityalloc]init], [[WeixinTimelineActivityalloc]init]];

UIActivityViewController*activityView = [[UIActivityViewControlleralloc]initWithActivityItems:@[@"这里是标题", [NSURLURLWithString:@"http://www.google.com"]]applicationActivities:activity];

activityView.excludedActivityTypes= @[UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypePrint,UIActivityTypePostToWeibo];

[selfpresentViewController:activityViewanimated:YEScompletion:nil];
