We have 2 files 'MainViewController' and 'View01'
The first file addSubView the second one.
In the first file we have a function named displayView.
I want to be able to call this function from the View01 file is the following code correct
part of View01 file
#import "MainViewController.h"
- (IBAction) changeView:id(sender){
MainViewControlle *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate displayView:2];
}
is this the correct way to do it?
at the moment I use the NSNotificationCenter to send activate the functions :)
You should try using delegate methods :-)
It works like that :
// Delegate
@protocol MyViewDelegate <NSObject>
- (void)myViewAskedForSomethingWithOrWithoutParameters;
@end
In your view you must have this parameter :
id<MyViewDelegate> delegate;
And then in your Controller you must implement the delegate
@interface MainViewController : UIViewController <MyViewDelegate> {
}
In your implementation you need to add a :
myView.delegate = self;
And finally in your view when you need to call the function, just do :
[ delegate myViewAskedForSomethingWithOrWithoutParameters ];
Good Luck !
