ios - presentModalViewController :animated is deprecated

Question

我在 XCode 中收到警告:

'presentModalViewController:animated:' is deprecated: first deprecated in iOS 6.0

在这行代码中:

[self presentModalViewController:initialSettingsVC animated:YES];

我尝试按照 documentation 中的建议替换它与:

[self presentModalViewController:initialSettingsVC animated:YES completion:nil];

我现在在 XCode 中得到一个错误:

No visible @interface for 'ViewController' declares the selector'presentModalViewController:animated:completion:'

有什么想法吗？

Answer 1

使用以下.........

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