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. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
