Handling Touch Events For UIButton in IOS

I recently used this code for handling touch events like touchesBegan,touchesMoved,touchesEnded  on UIButton in my project.

STEP 1:Create  UIButton Programmatically like this

1.UIButton *touchButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];

2.    touchButton.frame=CGRectMake(30, 30, 260, 50);

    [touchButton setTitle:@"TOUCH BUTTON" forState:UIControlStateNormal];

 3.   [touchButton addTarget:self action:@selector(touchBegan:withEvent:) forControlEvents: UIControlEventTouchDown];

 4.   [touchButton addTarget:self action:@selector(touchMoving:withEvent:) forControlEvents: UIControlEventTouchDragInside | UIControlEventTouchDragOutside];

  5.  [touchButton addTarget:self action:@selector(touchEnded:withEvent:) forControlEvents: UIControlEventTouchUpInside | UIControlEventTouchUpOutside];

6. [self.view addSubview:touchButton];

In the above code  adding selectors for different control events is important.

if you want to recognize touchBegan Method on UIButton,you have to write the selector method like this 

[touchButton addTarget:self action:@selector(touchBegan:withEvent:) forControlEvents: UIControlEventTouchDown];

if you want to recognize touchMoving Method on UIButton,you have to write the selector method like this 

[touchButton addTarget:self action:@selector(touchMoving:withEvent:) forControlEvents: UIControlEventTouchDragInside | UIControlEventTouchDragOutside];

if you want to recognize touchEnded Method on UIButton,you have to write the selector method like this 

[touchButton addTarget:self action:@selector(touchEnded:withEvent:) forControlEvents: UIControlEventTouchUpInside | UIControlEventTouchUpOutside];

STEP 2: Implement The Selector Methods For Touch Events Like this.

// this method calls whenever you touchDown on button

- (void)touchBegan:(UIButton *)control withEvent:event {

    NSLog(@"touchBegan called......");

    UITouch *touch = [[event allTouches] anyObject];

    CGPoint touchPoint = [touch locationInView:self.view];

    NSLog(@"In Touch Began: Touch x : %f y : %f", touchPoint.x, touchPoint.y);

    

}

// this method calls whenever you touchDragInside or touchDragOutside on button

- (void)touchMoving:(UIButton *)control withEvent:event {

    NSLog(@"touchMoving called......");

    UITouch *touch = [[event allTouches] anyObject];

    CGPoint touchPoint = [touch locationInView:self.view];

     NSLog(@"In Touch Moving  :Touch x : %f y : %f", touchPoint.x, touchPoint.y);

   }

// this method calls whenever you touchUp inside or touchUp outside on button

- (void)touchEnded:(UIButton *)addOnButton withEvent:event {

    NSLog(@"touchEnded called......");

    UITouch *touch = [[event allTouches] anyObject];

    CGPoint touchPoint = [touch locationInView:self.view];

    NSLog(@" In Touch Ended : touchpoint.x and y is %f,%f",touchPoint.x,touchPoint.y);

}

Thank You.....
