iOS 横屏调用相册 之 iPhone 也崩溃

 我在开发的时候，在做一个调用相册的项目，要求是横屏，所以iPhone、iPad都是横屏，两者调用相册的代码还不一样（这点大家注意哦！）我吧代码贴一下吧。

 

- (IBAction)openPictureLibFromSaved:(id)sender {

    //获取图片选取器

    UIImagePickerController *imagePicker = [[UIImagePickerControlleralloc]init];

    UIPopoverController *popC = [[UIPopoverControlleralloc]initWithContentViewController:imagePicker];

    //指定代理

    imagePicker.delegate =self;

    //打开图片后允许编辑

    imagePicker.allowsEditing =YES;

    [imagePickershouldAutorotate];

    

    imagePicker.sourceType =UIImagePickerControllerSourceTypePhotoLibrary;

    if ([[UIDevicecurrentDevice].modelhasPrefix:@"iPad"]) {

       NSLog(@"ipad");

        [popC presentPopoverFromRect:CGRectMake(0,0,200,200)inView:self.viewpermittedArrowDirections:UIPopoverArrowDirectionLeftanimated:YES];

    

    }elseif ([[UIDevicecurrentDevice].modelhasPrefix:@"iPhone"]){

        

       NSLog(@"iphone");

        

        [selfpresentViewController:imagePickeranimated:NOcompletion:^{}];

    }

}

 

关键的时候来了，这个时候运行在iPhone上面，会出现崩溃，

 

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

在iOS6 之后，解决办法是：

在appdelegate添加 
#if __IPAD_OS_VERSION_MAX_ALLOWED >= __IPAD_6_0 

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window 
{ 

return UIInterfaceOrientationMaskAll; 
} 

 

我试了，反正成功了，你呢？

最近也遇到开发横屏幕应用需要调用相册的问题，经过研究的确发现之前的结论存在问题，于是继续研究，发现两个解决途径，1、在调用相册开始给发送一个通知，支持UIInterfaceOrientationMaskAll，在调用即将结束时发送通知UIInterfaceOrientationLandscape。

 

2、iOS8之后使用AssetsLibrary.framework.很好使！贴一段代码：

Initialization and presentation

let pickerController = DKImagePickerController()
pickerController.pickerDelegate = self
self.presentViewController(pickerController, animated: true) {}

Delegate methods

func imagePickerControllerCancelled() {
    self.dismissViewControllerAnimated(true, completion: nil)
}

func imagePickerControllerDidSelectedAssets(assets: [DKAsset]!) {
    for (index, asset) in enumerate(assets) {

    }

    self.dismissViewControllerAnimated(true, completion: nil)
}

Configurable properties

/// The height of the bottom of the preview
var previewHeight: CGFloat = 80

var rightButtonTitle: String = "确定"

/// Displayed when denied access
var noAccessView: UIView
