Lol, sorry for making your life hard :P
let's write better. (Will be a problem in your computer with this font in
e-mail? )
//This is LevelUp.h
#import "LeveDown.h"
@interface LevelUp : NSObject {
}
-(void) init;
-(void)wantCallThisFunction
@end
//This is LevelUp.m
@implement LevelUp
-(void) init {
LevelDown *test = [[LevelDown alloc] init];
}
-(void)wantCallThisFunction {
///Do something
}
@end
//////////////////////////////
// levelDown.h
@interface LevelDown : UIView { //Some class
-(void) init;
-(void)keyboardWillShow;
}
@end
//LevelDown.m
@implement
-(void) init {};
-(void)keyboardWillShow {
//iOS automatic call this function
//I need to call wantCallThisFunction
}
Like I say, if I use this line in keyboardWillShow function :
[[NSNotificationCenter defaultCenter] postNotificationName:@"thisWork"
object:nil];
And to catch this call, in function init of LevelUp class , I have to use
this line
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(wantCallThisFunction)
name:@"thisWork" object:nil];
So the question is: there are another way to do that?
Now I am thinking that I have to remake the program and use a third object
that create instances of LevelUp and LevelDown in the same object. Am I
correct, or there are another way? I'm not remembering if java have problem
like that.
