iphone - 无法从 iphone 照片库中保存 UIImage

Question

我正在尝试通过从 iphone 照片库中挑选图像来保存图像。但我无法保存它。我的 UIImage 对象突然释放。我收到以下错误:* -[UIImage release]: 发送到释放实例 0x83fa5b0 的消息

请检查下面我的代码:

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

    NSLog(@"finish picking media");

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:@"public.image"]){

        UIImage *selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
        NSLog(@"found an image");

        selectedImage=[self scaleAndRotateImage:selectedImage];
        NSLog(@"image scaled");
        //add image to mainpic
        imgvwProfile.image = selectedImage;
        NSLog(@"11");
        //[ setImage:selectedImage forState:UIControlStateNormal];
        self.imgPic=selectedImage;
        //self.isMainPicImageModified=YES;
        NSLog(@"22");
        //[self sendImage:selectedImage];
        NSLog(@"selectedimage width:%f ht:%f",selectedImage.size.width,selectedImage.size.height);
        [self saveImage:selectedImage withImageName:@"profilePic.png"];
        NSLog(@"33");
    }
}

错误出现在 NSLog(@"11");已执行。有人可以帮我解决这个错误吗？

您能否更改以下行并检查此语句是否有问题。

 imgvwProfile.image = selectedImage;
                To
 imgvwProfile.image = [selectedImage retain];

现在让我知道您的应用程序是否在此功能中崩溃。
