Following the solution (the highest-voted answer actually) at UITextField Example in Cocos2d, I managed to do it except the line
[[[UIApplication sharedApplication] delegate] specifyStartLevel];
I have placed it in my scene, I get this warning:
Instance method '-specifyStartLevel' not found (return type defaults to 'id')
Why is that? I clearly have -specifyStartLevel
defined in the header and implementation of my AppDelegate...
Edit: Declaration of specifyStartLevel
#import <UIKit/UIKit.h>
@class RootViewController;
@interface AppDelegate : NSObject <UIApplicationDelegate,UITextFieldDelegate> {
UIWindow *window;
UITextField *levelEntryTextField;
RootViewController *viewController;
}
- (void)specifyStartLevel;
@property (nonatomic, retain) UIWindow *window;
@end
And implementation:
- (void)specifyStartLevel
{
[levelEntryTextField setText:@""];
[window addSubview:levelEntryTextField];
[levelEntryTextField becomeFirstResponder];
}
