请帮助。我正在使用UIImagePickerController从图库中选择图片。我在所有iPhone上工作得很好。但它在iPad iOS 8.0.2中崩溃了。显示图像选择器控制器。（所有照片和最近添加的）选项显示。但是，当我点击上面任何一个时，应用程序崩溃..这只发生在iPad iOS 8.0.2。

Answer 1

在iPad上，present image picker的正确方法是使用popover。检查official document。另请检查example

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
    //Present in Popover
} 
else 
{
    self presentViewController:imagePickerController animated:YES completion:nil];
}

UIImagePickerController在Ipad ios 8.0.2上崩溃但在iphone上工作正常
