iphone - 奇怪的错误 : wait_fences: failed to receive reply: 10004003

Question

我知道还有其他问题可以解决此错误，但这些答案对我没有任何帮助。我想知道是否有人知道确切原因，如果没有人知道，这里是代码:

-(void) imagePickerController : (UIImagePickerController *) picker
        didFinishPickingImage : (UIImage *) image
                  editingInfo : (NSDictionary *) editingInfo {

    self.imageView.image = image;
    [picker dismissModalViewControllerAnimated:YES];
    [picker release];
    //[self myNextResponder];
}

此错误:wait_fences: failed to receive reply: 10004003，在此方法退出后立即出现。我已经用谷歌搜索过了，但无法弄清楚。

Answer 1

您似乎将选择器对象用作 present/dismissModalViewController 的调用者。该文档建议使用“父” View Controller 。

对于“ parent ”，我使用了 self.navigationController(因为它不会去任何地方)

我的选取器委托(delegate)的取消方法的实现如下所示...

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    // make sure the picker doesn't try to access the soon to die delegate
    picker.delegate = nil;

    [self.navigationController dismissModalViewControllerAnimated:YES];
    [self.navigationController popViewControllerAnimated:YES];
}
