Question

我正试图在ipad横向模式下显示我的UIImagePicker ..

我遵循了这个例子：https://github.com/guillermomuntaner/GMImagePicker

但我收到以下错误：

<UIView: 0x7f8c9d158800; frame = (0 0; 1024 768); autoresize = W+H; layer = <CALayer: 0x7f8c9d14f090>>'s window is not equal to <LoginRegisterViewController: 0x7f8c9ac51a70>'s view's window!

我的代码是：

        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        picker.delegate = self;
        picker.modalPresentationStyle = UIModalPresentationPopover;

        UIPopoverPresentationController *popPC = picker.popoverPresentationController;
        popPC.permittedArrowDirections = UIPopoverArrowDirectionDown;
        popPC.sourceView = btnImagemPerfil;
        popPC.sourceRect = btnImagemPerfil.bounds;
        NSLog(@"%@", NSStringFromCGRect(btnImagemPerfil.bounds));
        [self showViewController:picker sender:sender];

和来自btnImagemPerfil.bounds的日志

{{0, 0}, {141, 141}}

将我的代码更新为：

    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
    appDelegate.window.rootViewController = self;

 UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        picker.delegate = self;
        picker.modalPresentationStyle = UIModalPresentationPopover;

        UIPopoverPresentationController *popPC = picker.popoverPresentationController;
        popPC.permittedArrowDirections = UIPopoverArrowDirectionDown;
        popPC.sourceView = btnImagemPerfil;
        popPC.sourceRect = btnImagemPerfil.bounds;
        NSLog(@"%@", NSStringFromCGRect(btnImagemPerfil.bounds));
        [self showViewController:picker sender:sender];
