Question

I am trying to see if a string has more than 6 characters in it. If it does it is not valid, and like wise for the other.

My problem is I am trying to call this method in a different method. I am not passing anything but instead I am using a NSString globally.

NSString *string = @"123456";
-(BOOL) isValid{

if ([string length] > 6) {
    return YES;
}
else {
    return NO;
}}

How do I call this function from another function without passing anything in the parameter?

Answer 1

If the methods are in the same class:

[self isValid];

otherwise:

[someObject isValid];
