Question

我正在使用CPJoystick，可在此处找到。 https://github.com/Wense/CPJoystick

我正在使用Xcode 4.6，断点在那里停止。

@property (nonatomic, weak,   readwrite) id<CPJoystickDelegate> delegate;

所以我做了一些改变。我已经下载了数百名代表，甚至尝试过这个代理：Custom delegate not working

我尝试了很多：

@property (nonatomic, strong, readwrite) id<CPJoystickDelegate> delegate;
@property (nonatomic, strong) id<CPJoystickDelegate> delegate;
@property (nonatomic, retain) id<CPJoystickDelegate> delegate;
@property(nonatomic,assign)id delegate;

我不明白我在做什么。我困住了五个星期，感到很困惑。

CPJoystick.h

@protocol CPJoystickDelegate <NSObject>
@required
- (void) ShowthisNumbers:(NSString*)text;
@optional
// - (void) ShowthisNumbers:(NSString*)text;
-(void)cpJoystick:(CPJoystick *)aJoystick didUpdate:(CGPoint)movement;
@end

CPJoystick.m

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
     ...
     [delegate ControlPosition:@"Touched"];

}

我甚至无法让这件事在UIViewController上与UILabel进行通信＆lt; CPJoystickDelegate＆gt; 操纵杆似乎工作正常，但UILabel无法正常工作。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    CPJoystick *joystick = [[CPJoystick alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
    [joystick setThumbImage:[UIImage imageNamed:@"handleImage.png"] andBGImage:[UIImage imageNamed:@"bgImage.png"]];

    [joystick setMovementUpdateInterval:1.0/30];
    [self.iSneaky addSubview:joystick];
    [joystick setMoveViscosity:4 andSmallestValue:0.09]; //defaults are 7 and 0.09


}
-(void)ControlPosition:(NSString*)text;
{

    amountLabel.text = text;
}

-(void)cpJoystick:(CPJoystick *)aJoystick didUpdate:(CGPoint)movement                                
{
NSLog(@"x = %f",movement.x);
NSLog(@"y = %f",movement.y);                                                                                                    
    character.center = CGPointMake(character.center.x + movement.x, character.center.y +     movement.y);
}

任何人都可以帮助我....我需要一些新鲜空气。

您的viewDidLoad方法似乎没有设置代表。

CPJoystick *joystick = [[CPJoystick alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
[joystick setThumbImage:[UIImage imageNamed:@"handleImage.png"] andBGImage:[UIImage imageNamed:@"bgImage.png"]];

[joystick setMovementUpdateInterval:1.0/30];
[self.iSneaky addSubview:joystick];
[joystick setMoveViscosity:4 andSmallestValue:0.09]; //defaults are 7 and 0.09
joystick.delegate = self;

操纵杆无法与UILabel沟通（强大，保留，弱势等......）
