In my application i have three uiimageview which is moving randomly. on single tap on imageview it should hide. But my tapgesture is not working. on single tap it is not getting hide.
- (void)showAlert1:(UITapGestureRecognizer *)sender
{
if (image1.tag == 1)
{
image1.hidden = TRUE;
}
else
{
image1.hidden = FALSE;
}
}
- (void)showAlert2:(UITapGestureRecognizer *)sender
{
if (image1.hidden == TRUE && image3.hidden == FALSE)
{
image2.hidden = TRUE;
}
else
{
image2.hidden = FALSE;
}
}
- (void)showAlert3:(UITapGestureRecognizer *)sender
{
if (image1.hidden == TRUE && image2.hidden == TRUE)
{
image3.hidden = TRUE;
}
else
{
image3.hidden = FALSE;
}
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (image1.tag == 1)
{
image1.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(imageAlerts];
tap.numberOfTapsRequired = 1;
[image1 addGestureRecognizer:tap];
}
if (image2.tag == 2)
{
image2.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(showAlert2];
tap.numberOfTapsRequired = 1;
[image2 addGestureRecognizer:tap];
}
if (image3.tag == 3)
{
image3.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(showAlert3];
tap.numberOfTapsRequired = 1;
[image3 addGestureRecognizer:tap];
}
}
Can anyone help me?
Thanks in advance
Please checkmark the userInteractionEnabled and multipleTouch in xib file if you have added image in xib
or
image.userInteractionEnabled = YES;
image.multipleTouchEnabled = YES;
in ViewDidLoad
Did you implement UIGestureRecognizerDelegate and set in to self?
try this -
- (void)viewWillAppearBOOL:animated
{
[super viewWillAppear:animated];
if (image1.tag==1)
{
image1.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(showAlert1:];
tap.numberOfTapsRequired = 1;
[image1 addGestureRecognizer:tap];
}
if (image2.tag==2)
{
image2.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(showAlert2:];
tap.numberOfTapsRequired = 1;
[image2 addGestureRecognizer:tap];
}
if (image3.tag==3)
{
image3.userInteractionEnabled = YES;
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTargetelf actionselector(showAlert3:];
tap.numberOfTapsRequired = 1;
[image3 addGestureRecognizer:tap];
}
}
Also it has memory leak. UIGesture is not released after it adds to image.
Try this
- (void)showAlert1:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
// your handling code
if (image1.tag==1)
image1.hidden=TRUE;
else
image1.hidden=FALSE;
}
}

{
[self performSegueWithIdentifier:#"loginsegue" sender:self];
}
}
Enable userInteractionEnabled on the label
label.userInteractionEnabled = YES;
I want the user to be able to pan from each thumb simultaneously but I can't figure out how to detect it with uigesturerecognizer. I can detect a tap and a pan simultaneously no problem.
It appears that the second pan will block the first.
Any help is appreciated.
I solved it by defining shouldReceiveTouch like so:
-(BOOL) gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
if (gestureRecognizer == singleTap) {
return YES;
}
if (gestureRecognizer == pan1 && [touch locationInView:self].x > 160) {
return YES;
}
if (gestureRecognizer == pan2 && [touch locationInView:self].x <= 160) {
return YES;
}
return FALSE;
}
And initWithFrame has the following code:
self.userInteractionEnabled = YES;
singleTap = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(handleSingleTap:)];
singleTap.numberOfTapsRequired = 1;
[self addGestureRecognizer:singleTap];
[singleTap release];
NSLog(#"tap: %p", singleTap);
pan1 = [[UIPanGestureRecognizer alloc]
initWithTarget:self action:#selector(handlePan1:)];
[self addGestureRecognizer:pan1];
NSLog(#"pan1: %p", pan1);
pan2 = [[UIPanGestureRecognizer alloc]
initWithTarget:self action:#selector(handlePan2:)];
[self addGestureRecognizer:pan2];
for (UIGestureRecognizer *recognizer in self.gestureRecognizers) {
recognizer.delegate = self;
}
NSLog(#"pan2: %p", pan2);
good day.. I have this code.. and this two is for actionAnimating Button and stopAnimating Button..I just want to know if how to make those two button integrate in ONE button.. for example.. I click the button then it animates.. when I click again that actionAnimating Button, i want to cancel/stop the animation at the same time i want to play/animate again.. in short i want to cancel the animation when i click again the actionAnimating button..

Hm...
you want to start/stop in one button?
BOOL isAnimating = NO;

if (!isAnimating) {
isAnimating = YES
// start animation
} else {

This is the error i am getting now:
-[CUETutorialSixteenClusterRootController handleSwipeFrom:]: unrecognized selector sent to instance 0x79b71b0
2012-03-28 13:25:55.724 CUETrainer[1788:11f03] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CUETutorialSixteenClusterRootController handleSwipeFrom:]: unrecognized selector sent to instance 0x79b71b0'
But its not actually doing anything.
Please help!!!!
The error says unrecognized selector sent to instance 0x79b71b0' most probably the names in .h and .m are different..
The target of the gesture recognizer needs to be the object that implements the selector. What's happening now when a swipe happens is that the gesture recognizer is doing [self.gestureReceiverButton handleSwipeFrom:recognizer]
You probably want this:
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(handleSwipeFrom:)];
Change every instance of:
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(handleSwipeFrom:)];
to
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(handleSwipe:)];
Problem solved. Be very careful with your #selectors, what you place in this macro is NOT validated by the compiler. Code complete will help you with this.
Also you are adding four gesture recognizers to one view, while you can accomplish the same task with one. You can combine the valid directions using the bitwise OR operator, like so:
[recognizer setDirection:(UISwipeGestureRecognizerDirectionUp | UISwipeGestureRecognizerDirectionDown)];
Hey, guys, I met a problem when trying to removeGestureRecognizer: from a view,
what i want to do is doubleTap one of the imageViews, and remove the tapped imageView's singleTap Gesture, without remove other imageViews singleTap Gesture.
here is how i generate views, gestures and the mechanisms:
.h
UITapGestureRecognizer *singleTap;
.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSInteger i;
for (i = 1; i <= 3; i++)
{
UIImageView *imageView = [[UIImageView alloc] init];
imageView.frame = CGRectMake(110, 70+80*(i-1), 100, 60);
imageView.backgroundColor = [UIColor whiteColor];
imageView.tag = i;
imageView.userInteractionEnabled = YES;
[self.view addSubview:imageView];
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(doubleMethod:)];
doubleTap.numberOfTapsRequired = 2;
singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(singleMethod:)];
[singleTap requireGestureRecognizerToFail:doubleTap];
[imageView addGestureRecognizer:doubleTap];
[imageView addGestureRecognizer:singleTap];
}
}
- (void)singleMethod: (id)sender
{
NSLog(#"SingleTap");
}
- (void)doubleMethod: (id)sender
{
NSLog(#"%d",[((UITapGestureRecognizer *)sender).view.gestureRecognizers count]);
UIImageView *imageView = nil;
NSArray *tryToFindYou = [self.view subviews];
for (imageView in tryToFindYou)
{
if ([imageView isKindOfClass:[UIImageView class]] && imageView.tag == ((UITapGestureRecognizer *)sender).view.tag)
{
[imageView removeGestureRecognizer:singleTap];
}
}
NSLog(#"%d",[((UITapGestureRecognizer *)sender).view.gestureRecognizers count]);
}
but these lines I wrote can't find exactly the singleTap Gesture attached to the double-tapped imageView.
when NSLog the .gestureRecognizers count, it still 2, what it removed is the last imageView's singleTap Gesture, it became 1, which is correct.
I can't locate the first and second one, any ideas to locate them? thank you for reading :)
You should cycle through gestureRecognizers property of the UIView class, where the gestures are added, something like this:
for (imageView in tryToFindYou)
{
if ([imageView isKindOfClass:[UIImageView class]] && imageView.tag == ((UITapGestureRecognizer *)sender).view.tag)
{
for(UIGestureRecognizer *gesture in [imageView gestureRecognizers])
{
if([gesture isKindOfClass:[UITapGestureRecognizer class]])
{
if (gesture.numberOfTapsRequired == 1)
[imageView removeGestureRecognizer:gesture];
}
}
}
}
