适用于iPhone 4s的iOS 8+中的UIImagePickerController屏幕问题

Question

我正在开发通用应用程序。我已经实现了图像选择器和代码，如下所示。

 isimagepiking=TRUE;
imgPicker = [[UIImagePickerController alloc] init];
imgPicker.sourceType =  UIImagePickerControllerSourceTypePhotoLibrary;
NSArray *mediaTypesAllowed = [NSArray arrayWithObject:@"public.image"];
[imgPicker setMediaTypes:mediaTypesAllowed];
imgPicker.delegate = self;
imgPicker.allowsEditing = YES;
imgPicker.wantsFullScreenLayout=true;
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
    [self presentViewController:imgPicker animated:YES completion:nil];
}

Bellow code print 480 作为尺寸。

 NSLog(@"%f",imgPicker.view.frame.size.height);

这款iphone 5 + ios 8.3以及ios 7.1以下iphone 4的功能正常，但 iphone 4s ios 8 + 选择器不显示< strong>选择和取消按钮

使用ios 7.1 iphone 4s进行屏幕显示。

使用iOS 8.2 iPhone 4s的屏幕 - 未显示选择或取消按钮

似乎在iOS 8+中它的uiscreen尺寸为4英寸。 任何人都可以帮助我。

先谢谢

我希望提出观点正在解决问题。试试addSubview

isimagepiking=TRUE;
    imgPicker = [[UIImagePickerController alloc] init];
    imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    NSArray *mediaTypesAllowed = [NSArray arrayWithObject:@"public.image"];
    [imgPicker setMediaTypes:mediaTypesAllowed];
    imgPicker.delegate = self;
    imgPicker.allowsEditing = YES;
    imgPicker.wantsFullScreenLayout=true;

    //  Try Adding imagepicker as a subview
    [self createAnimationsinView:self.view];
    [self.view addSubview:imgPicker.view] ;

如果您想要一个当前的视图控制器动画，也可以这样做。

//呈现视图控制器动画

-(void)createAnimationsinView:(UIView*)view{
    CATransition* transition = [CATransition animation];
    transition.duration = 0.5;
    transition.type = kCATransitionMoveIn;
    transition.subtype =kCATransitionFromTop;
    [view.window.layer addAnimation:transition forKey:kCATransition];
}
