presentPopoverFromRect:inView:permissedArrowDirections:iOS 6.0 中的动画崩溃[重复]

StackOverflow https://stackoverflow.com//questions/12667050

题

我刚刚从 iOS 5.1.1 升级到 6.0，当以下代码路径尝试显示一个以 imagePickerViewController 作为其 contentVC 的弹出窗口以允许用户从 photoLibrary 选择图像或视频时，SIGTRAP 会导致以下代码路径崩溃。

它在 5.1.1 上运行得很好。我已经解决这个问题几天了，但没有任何进展。有人能处理这个问题吗？iOS6.0有替代方法吗？如果需要，我可以添加更多代码...

我可以使用以下行捕获图像和视频：

[self presentViewController:self.imagePickerViewController.imagePickerController animated:YES completion:NULL];

这是用户触摸 UIButton 后完整调用的方法。

- (void)showImagePicker:(UIImagePickerControllerSourceType)sourceType mediaType:(NSString *)mediaType
{
    if (self.capturedMovies.count > 0)
        [self.capturedMovies removeAllObjects];

    if ([UIImagePickerController isSourceTypeAvailable:sourceType])
    {
        [self.imagePickerViewController setupImagePicker:sourceType mediaType:mediaType];

        if (sourceType == UIImagePickerControllerSourceTypeCamera) { // WORKS
            [self presentViewController:self.imagePickerViewController.imagePickerController animated:YES completion:NULL];
        }
        else if (sourceType == UIImagePickerControllerSourceTypePhotoLibrary) { 
        //else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie] || [mediaType isEqualToString:(NSString *)kUTTypeImage]) {

            if (!self.moviePickerPopoverController) {
                self.moviePickerPopoverController = [[UIPopoverController alloc] initWithContentViewController:self.imagePickerViewController.imagePickerController];
            }

            UIView *uiViewObject = self.mediaTitleTextField;

            CGFloat xLocation = uiViewObject.frame.origin.x;
            CGFloat yLocation = uiViewObject.frame.origin.y;

            CGFloat width = uiViewObject.bounds.size.width;
            CGFloat height = uiViewObject.bounds.size.height;

            // CRASHES HERE!!!
            [self.moviePickerPopoverController presentPopoverFromRect:CGRectMake(xLocation, yLocation, width, height)
                                                               inView:self.view
                                             permittedArrowDirections:UIPopoverArrowDirectionAny
                                                             animated:YES];
        }
    }
}

以下是代码窗口中弹出的内容：

主题 1：第 3 行发出 SIGTRAP 信号：

libsystemkernel.dylib`_kill:
0x394e7830: mov r12, #37
0x394e7834: svc #128
0x394e7838: blo 0x394e7850 ; __kill + 32 <<<<<<<<< Thread 1: signal SIGTRAP
0x394e783c: ldr r12, [pc, #4] ; __kill + 24
0x394e7840: ldr r12, [pc, r12]
0x394e7844: b 0x394e784c ; __kill + 28

0x394e784c: bx r12
0x394e7850: bx lr

这是调试器的回溯：

有帮助吗？

解决方案

这是重复的 https://stackoverflow.com/a/12575058/1074338

另外，我应该触摸调试器上的“执行”按钮......它揭示了有问题的代码：

enter image description here

*** Terminating app due to uncaught exception
'UIApplicationInvalidInterfaceOrientation',
 reason: 'Supported orientations has no common orientation
 with the application, and shouldAutorotate is returning YES'
