Question

当我在iPhone上使用UIImagePicker时，应用程序崩溃，但仅在 iOS 7 上使用。我使用以下代码行

    picker = [[UIImagePickerController alloc] init];

    picker.delegate = self;
    picker.allowsEditing = YES;

    if( [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront] || [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear])
    {
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    } else {
        //[self showAlertViewWithTitle:@"Sorry" message:@"Your Device Don't Have Camera"];
    }

    [self presentViewController:picker animated:YES completion:nil];

}

该应用程序在iOS 6上运行，而不是在iOS 7中运行。我是这个网站的新用户，请帮忙。

UIImagePickerController仅在Potratin模式下显示在iPhone中。我发现你的代码中还有一个错误，你使用的是picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary isCameraDeviceAvailable而错误的错误： -

你应该编码如下： -

if( [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront] || [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear])
    {
       picker.sourceType = UIImagePickerControllerSourceTypeCamera;
                 [self presentViewController:picker animated:YES completion:nil];
    } else {
         picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                 [self presentViewController:picker animated:YES completion:nil];       
    }

并将您的ViewController shouldAutorotate更改为NO而不是YES

Answer 2

在启动@implementation之前在ViewController.m文件中编写以下代码

@interface NonRotatingUIImagePickerController : UIImagePickerController

@end

@implementation NonRotatingUIImagePickerController

- (BOOL)shouldAutorotate
{
    return NO;
}

@end

您要在哪里创建Image Picker对象，请编写以下代码

UIImagePickerController* picker = [[NonRotatingUIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self; 
    [self presentModalViewController:picker animated:YES];

Answer 3

如果是这样的话，请尝试this ...

将此添加到您的ViewController

- (NSUInteger) supportedInterfaceOrientations
{
     //Because your app is only landscape, your view controller for the view in your
     // popover needs to support only landscape
     return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

应用程序在iOS 7中崩溃
