我正在使用简单的“UIImagePickerController”解决内存问题。我收到两个内存警告:一个在我拍摄图像时,一个在我触摸“使用”按钮时......最好的是,这只会附加在 4S 上(恰好是我老板的电话)。我什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,这是能够重现问题的最简单的例子:
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有解决方案?
非常感谢!
