UIImagePickerController 照片快门未打开

Question

我正在开发仅支持横向的 iPad 应用程序

我想要做的是，我想在按钮点击时打开照片库。 这是我的代码sn-p，

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.modalPresentationStyle = UIModalPresentationCurrentContext;

当我写这篇文章时，它没有打开照片库:( 我不知道我在哪里做错了

请提前帮助和感谢。

试试这个：

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

if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0)
{
    [[NSOperationQueue mainQueue] addOperationWithBlock:^{
        [self presentViewController:picker animated:NO completion:nil];
    }];
}else{
    [self presentViewController:picker animated:YES completion:nil];
}
