Question

我正在使用iPhone相机拍摄图像，并调整大小并添加圆角。我有一些用户抱怨崩溃，我似乎无法找到问题。此外，选择图像后代码运行速度非常慢。

有人可以提出改进以下方法的建议吗？

-(void)imagePickerController:(UIImagePickerController *)imagePicker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    [self dismissModalViewControllerAnimated:YES];

    CGSize newSize = CGSizeMake(500, 500);
    UIGraphicsBeginImageContext( newSize );
    [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    NSData *picAsPNG = UIImagePNGRepresentation(newImage);

    self.imageView.image = newImage;

    self.passedItem.itemImage = picAsPNG;
    self.eraseButton.hidden = NO;
    self.scrollImageButton.enabled = YES;
}

这可能是内存问题吗？我知道UIImagePicker经常会在旧设备上引起内存警告：你是否在内存上发布任何警告警告你以后会在那里发出警告？
