Question

我正在使用静态librrary，其中有一个使用UIImagePickerViewController的类。我已将委托设置为它并在该类中编写didFinishPickingMediaWithInfo：方法。我想要的是打开前置摄像头，在用户点击图像时捕获图像，然后将其保存到相册。我的代码发生的是UIImagePickerController加载相机，当我点击＆＃34;使用照片＆＃34;按钮。但在那之后，它会冻结但不会崩溃。之后我无法点击任何地方。任何帮助赞赏。感谢

//图书馆代码

+ (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage* photo = (UIImage*) [info objectForKey:UIImagePickerControllerOriginalImage];

    NSData *data = UIImagePNGRepresentation(photo);

    photo = [UIImage imageWithCGImage:[UIImage imageWithData:data].CGImage
                                   scale:photo.scale
                             orientation:photo.imageOrientation];

    UIImageWriteToSavedPhotosAlbum(photo, self, nil, nil);

    // TRIED ALL OF THE BELOW BUT NOTHING WORKS FOR ME

    [picker dismissViewControllerAnimated:NO completion:nil];
    // [picker dismissModalViewControllerAnimated:YES];
    [picker.view.superview removeFromSuperview];
    //    [picker release];
    //    picker=nil;
}

您的方法不应该是静态的 - 删除＆＃39; +＆＃39;并将其替换为＆＃39; - ＆＃39;。

另外，在你做的方法

[picker.view.superview removeFromSuperview];

我不确定你想做什么！

所以你的代码变成了：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    ...
}

UIImagePickerViewController在iOS中冻结
