Question

I can’t figure out why the code in if statement is not executed

 NSString *str = @"capitalizedString";
    NSString *name = @"chris";

    SEL selector = NSSelectorFromString(str);

    if([NSString respondsToSelector:selector]) {
        NSLog(@"%@", [name performSelector:selector]);
    }

EDIT //
This code works fine

NSString *color = @"blueColor";
SEL selector = NSSelectorFromString(color); 
    if([UIColor respondsToSelector:selector])
    {
        myColor = [UIColor performSelector:selector];
    }

Answer 1

capitalizedString is not a static method. So you can not use NSString directly. Instead you should use the object of it. In your case it could ne name or str.
