ios - 在 iPhone 的 iOS 7 中打开相机时横向模式下的方向问题

Question

我有一个仅处于横向模式的应用程序。在我的应用程序中，我从我的一个 View 中打开相机。它在我的 iPad 上运行良好，但在 iPhone 上它崩溃了。它在 iOS 6 中运行良好，但该应用程序在 iOS 7 中崩溃并且仅适用于 iPhone。

下面是我的代码。

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{

    ipc=[[UIImagePickerController alloc] init ];
    ipc.delegate=self;
    ipc.sourceType=UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:ipc animated:YES completion:nil];
} 
else {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Desc" message:@"Camera capture is not supported in this device" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    [alert release];
}

如何解决这个问题？

当我选择从相机捕捉时它崩溃了。它不会从上面的代码中崩溃，但之后它会因以下错误而崩溃。

我收到此错误:

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

我的应用程序崩溃了。

我在这个 View 上的方向代码。

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight ;
}

我以前也遇到同样的问题。我按照步骤操作。请试试这个，让我知道你是否面临同样的问题。

第1步:
checkin appdelegate.m

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
     return UIInterfaceOrientationMaskAll;
}

第 2 步:在您的 View Controller 中

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
if (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight)
    return YES;
    return NO;
}

第 3 步:您的 View Controller

-(IBAction)TakePhoto:(id)sender{

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
    {
       UIImagePickerController*    imagePicker = [[UIImagePickerController alloc] init];
        imagePicker.delegate = self;
        imagePicker.allowsEditing = YES;
        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
        [self.view.window.rootViewController presentViewController:imagePicker animated:YES completion:nil];//add to view as per requirement
    }
    else
    {
        UIAlertView *noCam = [[UIAlertView alloc] initWithTitle:@"Notification" message:@"There is No Camera Fecility" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [noCam show];
    }
}
