Answer:
@ leonid3452 , Good time of the day! I will try to explain it with my example. Let's say there are two classes:
"ViewController : UIViewController" и "DetailController : UIViewController"
And we need to pass the method:
- (void)displayLog с "ViewController" в "DetailController"
And so, let's move on to the implementation: 1 what you need to do make sure that the method is declared in "ViewController.h" will look something like this:
//ViewController.h
@interface ViewController : UIViewController
{
}
- (void) displayLog;
@end
Let's go to ViewController.m and implement the method:
//ViewController.m
@interface ViewController ()
@end
@implementation ViewController
- (void) displayLog
{
NSLog(@"Hello");
}
@end
Next, you need to call this method (- (void) displayLog;) in DetailController, say by clicking on the button, we implement:
//DetailController.h
@interface DetailController : UIViewController
{
}
- (IBAction)button:(id)sender;
@end
Go to .m:
//DetailController.m
@interface DetailPassword ()
@end
@implementation DetailPassword
- (IBAction)button:(id)sender
{
ViewController *viewCon = [[ViewController alloc] init];
[viewCon displayLog];
}
@end
I hope I have explained it clearly. If you do not understand anything, ask questions.
