Question

The following code does work, but it still makes me frustated because in the else block the deprecated method call leads to a warning.

if ([self.navigationController respondsToSelector:@selector(dismissViewControllerAnimated:completion:)])
{
    [self.navigationController dismissViewControllerAnimated:YES completion:nil];
}
else
{
    //Here,the warning goes!
    //dismissModalViewControllerAnimated is deprecated
    [self.navigationController dismissModalViewControllerAnimated:YES];
}

How can I hide the warning dismissed, or is there any other way to solve the problem?

You can temporarily disable deprecation warnings around the line of code in question:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"

[self.navigationController dismissModalViewControllerAnimated:YES];

#pragma clang diagnostic pop
