NSString * regexName = @”[a-zA-Z] * “;

NSString *testString = @"your string";

NSPredicate *predicate;
predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regexName];

if ([predicate evaluateWithObject:testString]) {
    NSLog(@"true");        
}

else{NSLog”string contains numbers or special characters” ;}
