Question

我正在使用简单的“UIImagePickerController”来解决内存问题。我得到两个内存警告：一个在我拍摄图像时，一个在我触摸“使用”按钮时... 最好的是，这仅仅附加在4S上（恰好是我老板的电话）。我甚至无法在其他型号的iPhone上重现此错误（在3G，3GS，4和5上测试）。

我尝试了不同的东西，这是最简单的例子，可以重现问题：

UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

picker.delegate = self;

[self presentModalViewController:picker animated:YES];

[picker release];

我实现了委托方法：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [picker dismissModalViewControllerAnimated:YES];
}


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

// should do something with the [[info objectForKey:UIImagePickerControllerOriginalImage] retain];

    if (picker.sourceType == UIImagePickerControllerSourceTypeCamera)
        UIImageWriteToSavedPhotosAlbum(selectedImage, nil, NULL, nil);

    [picker dismissModalViewControllerAnimated:YES];

}

有谁知道这个问题并希望解决方案？

非常感谢！

这很常见。只要您处理内存警告而不会崩溃并且有足够的空间继续运行，请不要让它驱动...
