iphone - presentModalViewController:Animated 在 ios6 中已弃用

Question

我将以下代码用于图像选择器。但是当我在模拟器中运行它时，我遇到了内存泄漏，并且我收到了关于presentModalViewcontroller:animated在 iOS6 中被弃用的警告。我也被dismissModalViewController:animated弃用了。我正在使用 SDK 6.1。

ImagePicker 的代码：

- (void)showAlbum:(id)sender { 
    imagePicker=[[UIImagePickerController alloc]init];
    imagePicker.delegate = self;
    imagePicker.allowsEditing =NO;
    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:imagePicker animated:YES];
}

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

Answer 1

使用此行并检查：

[self presentViewController:imagePicker animated:YES completion:nil];

Answer 2

[[Picker presentingViewController] dismissViewControllerAnimated:YES completion:nil];

代替

 [[Picker parentViewControl] dismissModalViewControllerAnimated:YES];

和

[self presentViewController:picker animated:YES completion:nil];

代替

[self presentModalViewController:picker animated:YES];

Answer 3

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)])
{
    [self presentViewController:objSignupViewController animated:^{} completion:nil];
}
else
{
    [self presentModalViewController:objSignupViewController animated:YES];
}

Answer 4

正如维沙尔所说

[self presentViewController:imagePicker animated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];

确保你也添加了“completion:nil”

Answer 5

采用：

[self presentViewController:imagePicker animated:YES completion:nil];

然后为您的解雇模式使用：

[self dismissViewControllerAnimated:controller completion:nil];

或者

[self dismissViewControllerAnimated:YES completion:nil];
