How to display the default iOS 6 share action sheet with available share options?
提问by openfrog
Some apps show a default action sheet in iOS 6 with sharing options.
一些应用程序在 iOS 6 中显示一个带有共享选项的默认操作表。
Social Frameworkonly has two classes, one for composing and one for request.
Social Framework只有两个类，一个用于编写，一个用于请求。
What I found though is about composing for a particular service with SLComposeViewController and before showing this I must query by hand if the service is available. And then I also have to create my own action sheet with own icons.
我发现的是关于使用 SLComposeViewController 为特定服务组合，在显示之前我必须手动查询该服务是否可用。然后我还必须使用自己的图标创建自己的操作表。
How do those apps show this default share options action sheet in iOS 6? Or are they using an open source framework?
这些应用程序如何在 iOS 6 中显示此默认共享选项操作表？或者他们使用的是开源框架吗？

The UIActivityViewControllerstated in the other answer makes this trivial. All you have to do is specify the text/image/URL that you want to share and present the activity view controller modally and iOS will automatically display all applicable sharing services. Examples:
另一个答案中所述的UIActivityViewController使这变得微不足道。您所要做的就是指定要共享的文本/图像/URL 并以模态方式呈现活动视图控制器，iOS 将自动显示所有适用的共享服务。例子：
Objective-C
目标-C
- (void)shareText:(NSString *)text andImage:(UIImage *)image andUrl:(URL *)url
{
NSMutableArray *sharingItems = [NSMutableArray new];
if (text) {
[sharingItems addObject:text];
}
if (image) {
[sharingItems addObject:image];
}
if (url) {
[sharingItems addObject:url];
}
UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];
[self presentViewController:activityController animated:YES completion:nil];
}
Swift
迅速
func share(sharingText: String?, sharingImage: UIImage?, sharingURL: URL?) {
let sharingItems:[AnyObject?] = [
sharingText as AnyObject,
sharingImage as AnyObject,
sharingURL as AnyObject
]
let activityViewController = UIActivityViewController(activityItems: sharingItems.compactMap({-(IBAction)shareButtonPressed:(id)sender {
NSLog(@"shareButton pressed");
NSString *texttoshare = _txt; //this is your text string to share
UIImage *imagetoshare = _img; //this is your image to share
NSArray *activityItems = @[texttoshare, imagetoshare];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePrint];
[self presentViewController:activityVC animated:TRUE completion:nil];
}
}), applicationActivities: nil)
if UIDevice.current.userInterfaceIdiom == .pad {
activityViewController.popoverPresentationController?.sourceView = view
}
present(activityViewController, animated: true, completion: nil)
}

Add this to use the UIActivityViewController.
添加此项以使用UIActivityViewController.
