Now i remember the problem about this solution.
To this work, LevelUp have to include LevelDown
and LevelDown have to include LevelUp. (This is a cyclic include and will
fail)
To solve this, I read in a book to use the @class. I do that.
LevelUp have a #import "levelDown.h"
and LevelDown have a @class LevelUp
Now the problem is that any function call cause problem because the compiler
don't found it.
In code is thing like this:
//This is the "LevelUp.h"
*#include "LevelDown.h"* //IF I use *@class*, it will have the same
problem
@interface LevelUp : UIViewController {
LevelDown *levelDown;
}
-(void) doSomething;
@end
//LeveUp.h only call in a correct place the line:
// LevelDown *test = [[LevelDown alloc] initWithLevelUp: self];
//So, the "LevelDown.h" is
*@class LevelUp;*
@interface LevelDown : UIViewController {
}
- (id)initWithLevelUp: (LevelUp *)levelUp;
@end
//Finally in "LevelDown.m" i have
#import "LevelDown.h"
@implementation *LevelDown*
- (id)initWithLevelUp: (LevelUp *)levelUp; {
self = [super init];
LevelUp* myLevelUp = levelUp;
[myLevelUp doSomething]; //Everything work, but this will give-me a
problem
return self;
}
@end
In the line that have problem, the XCode will show
- warning: no '-doSomething' method found
- warning: Semantic Issue: Method '-doSomething'' not found (return type
defaults to 'id')
But the method is correct. What I am doing wrong?
My problem is a little more complex than a simple line.
