iOS- UITapGestureRecognizer Gives EXC_BAD_ACCESS - ios

Question

I want to add click event in my custom header class.
Following is my code. When I click on Header area it gives EXC_BAD_ACCESS.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
UITapGestureRecognizer *singleFingerTap =
[[UITapGestureRecognizer alloc] initWithTarget:self
action:#selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleFingerTap];
}
return self;
}
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer {
CGPoint location = [recognizer locationInView:[recognizer.view superview]];
//Do stuff here...
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

Answer 1

//At View did load
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapDetected:)];
tapRecognizer.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tapRecognizer];
- (void)tapDetected:(UITapGestureRecognizer *)tapRecognizer
{
//addcodehere
}

If your custom header class is subclass of UIView means then use self instead of self.view
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
tapRecognizer.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tapRecognizer];
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer {
CGPoint location = [recognizer locationInView:[recognizer.view superview]];
//Do stuff here...
}

May be this will helpful for you......
{
UITapGestureRecognizer *tapGestureRecognizer;
self.view.backgroundColor = [UIColor whiteColor];
/* Create the Tap Gesture Recognizer */
self.tapGestureRecognizer = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(handleTaps:)];
self.tapGestureRecognizer.numberOfTouchesRequired = 2;
self.tapGestureRecognizer.numberOfTapsRequired = 3;
[self.view addGestureRecognizer:self.tapGestureRecognizer];
}
- (void) handleTaps:(UITapGestureRecognizer*)paramSender
{
NSUInteger touchCounter = 0; for (touchCounter = 0;
touchCounter < paramSender.numberOfTouchesRequired;
touchCounter++)
{
CGPoint touchPoint =
[paramSender locationOfTouch:touchCounter inView:paramSender.view];
NSLog(#"Touch #%lu: %#",(unsigned long)touchCounter+1, NSStringFromCGPoint(touchPoint));
}
}

Instead of doing in init method try to do in ViewDidLoad.
- (void)viewDidLoad
{
[super viewDidLoad];
UITapGestureRecognizer *singleFingerTap =
[[UITapGestureRecognizer alloc] initWithTarget:self
action:#selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleFingerTap];
// Do any additional setup after loading the view from its nib.
}
And include this method in class extension as,
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer ;
Or write it before viewDidLoad.
