Xcode : 通过操作分享内容 Sheet

Question

我想复制这种行为（见下图）并使用这种操作分享我的应用程序中的内容sheet。

问题是：

这真的是一个动作吗Sheet？我在任何地方都找不到 iOS 7 或 8 的教程。不确定如何继续。

共享选项是否取决于用户的配置？

将不胜感激。

Answer 1

您可以使用 UIActivityController 实现此结果 class。

请看看这个 link :- http://nshipster.com/uiactivityviewcontroller/

希望对您有所帮助！

Answer 2

它不在 UIActionSheet 中，它在 UIActivityController 中，这是 iOS 中的默认函数。

objective-C

- (void)presentActivityController:(UIActivityViewController *)controller {

    // for iPad: make the presentation a Popover
    controller.modalPresentationStyle = UIModalPresentationPopover;
    [self presentViewController:controller animated:YES completion:nil];

    UIPopoverPresentationController *popController = [controller popoverPresentationController];
    popController.permittedArrowDirections = UIPopoverArrowDirectionAny;
    popController.barButtonItem = self.navigationItem.leftBarButtonItem;

    // access the completion handler
    controller.completionWithItemsHandler = ^(NSString *activityType,
                                              BOOL completed,
                                              NSArray *returnedItems,
                                              NSError *error){
        // react to the completion
        if (completed) {
            // user shared an item
            NSLog(@"We used activity type%@", activityType);
        } else {
            // user cancelled
            NSLog(@"We didn't want to share anything after all.");
        }

        if (error) {
            NSLog(@"An Error occured: %@, %@", error.localizedDescription, error.localizedFailureReason);
        }
    };
}

-(void)sendMessage {
    //create a message
    NSString *theMessage = @"Some text we're sharing with an activity controller";
    NSArray *items = @[theMessage];

    // build an activity view controller
    UIActivityViewController *controller = [[UIActivityViewController alloc]initWithActivityItems:items applicationActivities:nil];

    // and present it
    [self presentActivityController:controller];
}

Swift

let shareText = "Hello, world!"

if let image = UIImage(named: "myImage") {
    let vc = UIActivityViewController(activityItems: [shareText, image], applicationActivities: [])
     present(vc, animated: true, completion: nil)
}
