objective-c - Xcode 社交媒体分享按钮

Question

是否有任何 Xcode 的内置 api/代码允许应用程序检测 iphone/ipad/ipod touch 中安装的其他社交媒体应用程序以填充共享功能？

听说安卓有这样的能力，iOS也有吗？

Answer 1

Twitter 集成内置于 iOS 5，请查看此链接http://developer.apple.com/library/ios/documentation/Twitter/Reference/TWTweetSheetViewControllerClassRef/Reference/Reference.html

对于 Facebook，您需要使用 Facebook SDK，请在此处查看http://developers.facebook.com/docs/reference/iossdk/

或者你可以试试 ShareKit... http://getsharekit.com/

或 GetSocialize... http://www.GetSocialize.com/

这两者都提供了功能下降。

Answer 2

- (IBAction) shareHasTapped: (id)sender {

    NSString *texttoshare = @"text to share";

    //  UIImage *imagetoshare = [UIImage imageNamed:@"beck.png"];

    NSArray *activityItems = @[texttoshare];

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

    activityVC.excludedActivityTypes =@[UIActivityTypeCopyToPasteboard, UIActivityTypePostToWeibo, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo];


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

}

Answer 3

使用 UIActivityViewController 共享图像社交网络：

-（无效）共享图像{

NSArray *objectsToShare = @[_s_image];
UIActivityViewController * avc = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

avc.excludedActivityTypes=@[UIActivityTypePostToTwitter];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
    [self presentViewController:avc animated:YES completion:nil];
}
else
{
    UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:avc];
    [popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/4, 0, 0)inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

}
