// Integrate with WeChat
NSArray *activity = @[[[WeixinSessionActivity alloc] init], [[WeixinTimelineActivity alloc] init]];

UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[string, image, URL] applicationActivities:activity];
[self.navigationController presentViewController:activityViewController animated:YES completion:nil];
注：微信需要在 application:didFinishLaunchingWithOptions: 中注册 app:
[WXApi registerApp:@"appId"];
这是从微信、微博等跳回来需要的设置，（注，微博的URL Schemes需在 appId 前面加 wb，微信的自带了 wx） ：
TARGETS -> Info -> URL Types -> 编辑 URL Schemes：添加唯一的字符串
