ios – UIActivity activityViewController被模拟地呈现在iPad上,而不是popover

Your app is responsible for configuring,presenting,and dismissing this view controller. Configuration for the view controller involves specifying the data objects on which the view controller should act. (You can also specify the list of custom services your app supports.) When presenting the view controller,you must do so using the appropriate means for the current device. On iPad,you must present the view controller in a popover. On iPhone and iPod touch,you must present it modally.

我把最后一行作为一个标志,你必须处理视图的呈现,所以我检查代码是否在iPad上运行,并相应地使用UIPopover.你可以在这里… https://github.com/bufferapp/buffer-uiactivity/blob/master/BufferUIActivity/Views/FirstViewController.m在以下的方法.

-(IBAction)openUIActivityView:(id)sender {

    NSString *text = @"Hello world";
    NSString *url = @"http://bufferapp.com";


    NSArray *activityItems = @[text,url];

    BufferUIActivity *bufferActivity = [[BufferUIActivity alloc] init];

    UIActivityViewController *activityView = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:@[ bufferActivity ]];


    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        [self presentViewController:activityView animated:YES completion:^{

        }];
    } else {
        // Change Rect to position Popover
        self.popup = [[UIPopoverController alloc] initWithContentViewController:activityView];
        [self.popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width/2,self.view.frame.size.width/2,100,100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    }

}
