UIImagePickerControllerCameraCaptureModePhoto在IOS 7中不起作用

Question

在IOS6中，我使用以下方法从I Pad照片库中获取照片。但现在它不适用于IOS7

UIImagePickerController* picker = [[UIImagePickerController alloc] init]; 
    picker.sourceType = UIImagePickerControllerCameraCaptureModePhoto; 
    picker.delegate = self; 

    UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
    [popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
    [picker release], picker = nil;

IOS7有什么问题

Answer 1

在这里你可以使用自定义框架并加载popover;）

[popOver presentPopoverFromRect:CGRectMake(self.view.frame.size.width-50, 50, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
