How can I make FirstViewController aware of the method in the second class?
I tried import and still got a warning.
FirstViewController.m
#import "FirstViewController.h"
#import "SecondViewController.h"
-(IBAction)buttonDown:(id)sender {
NSLog(@"id: %d", [sender tag] );
[SecondViewController populateTextFieldWithString:@"hey there"];
}
SecondViewController.m
-(void)populateTextFieldWithString:(NSString *)string {
NSLog(@"%@", string );
[commandText setText:string];
}
As soon as I call that method the app bombs... it has no idea what that
method in the SecondViewController is...
