How to stop warning for UIView may not respond to selector

I have a class that has a UIView as a property. Sometimes I pass in a UILabel; sometimes a UITextField. No matter which I pass in, I want the class to set the text. Currently I am doing this, which works:

if ([self.viewToUpdate respondsToSelector:@selector(setText:)] && !self.newAnswer)
    [self.viewToUpdate setText:[[self.choices objectAtIndex:indexPath.row] text]];

The problem is, this gives a warning, because even though I'm checking respondsToSelector, Xcode doesn't know that my UIView will respond to setText:. How can I remove this warning?

I know that I can specifically check to see if it's a TextField or a Label, and then cast to a TextField or a Label, respectively, but this would be a pain, and if I ever have more types of views, I'd have 开发者_运维问答to add a few more lines of code for each one.

I thought about creating my own protocol, and then having my class have id as the type for viewToUpdate... but of course UITextField and UILabel wouldn't conform to that protocol...

try just casting it as an id:

if ([self.viewToUpdate respondsToSelector:@selector(setText:)] && !self.newAnswer)
    [(id)self.viewToUpdate setText:[[self.choices objectAtIndex:indexPath.row] text]];
