iPhone App：触摸事件并将控制转移到其他对象

Question

在我的iPhone应用程序中，我想玩触摸事件。我的要求是：如图所示。

我正在Button 2 touch drag Exit事件中创建Button 1。这是代码

 -(IBAction)addView:(id)sender{

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.tag=count;
count++;
    [button addTarget:self action:@selector(imageTouch:withEvent:) forControlEvents:UIControlEventTouchDown];
    [button addTarget:self action:@selector(imageMoved:withEvent:) forControlEvents:UIControlEventTouchDragInside];
    [button addTarget:self action:@selector(imageTouchCancel:withEvent:) forControlEvents:UIControlEventTouchUpInside];

button.frame=CGRectMake(shape1.frame.origin.x-30,shape1.frame.origin.y-40, 100, 100);

   [button setImage:[UIImage imageNamed:imgname] forState:UIControlStateNormal];
   [button addSubview:close];
  [baseview addSubview:button];

 }

在这里我能够成功创建按钮2，但问题是我无法在单触式事件中拖动和移动按钮2，同时在按钮1上向外拖动它创建按钮2但是要移动按钮2我必须把手指从屏幕上移开，然后按下按钮2，我可以移动按钮2。

我的问题是如何创建button2并在单个触摸循环中将其移动到屏幕上？

请帮助和建议。

设置按钮UserInteraction禁用并使用以下代码..

[button2 setUserInteractionEnabled:NO];

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:touch.view];
button2.center = location;
}


-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchesBegan:touches withEvent:event];
 }
