This is my code and it does not work on tap. This is how I see my code: The control style of the player is initially hidden. The player view has a tap gesture recogniser in it. When it taps, I want to show the Controls appear :
- (void)viewDidLoad {
_player = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[_player.view setFrame:CGRectMake(0, 0, 540, 250)];
[self.view addSubview:_player.view];
_player.view.center = self.view.center;
//Control style is None
_player.controlStyle = 0;
//Gesture
tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTap:)];
[_player.view addGestureRecognizer:tap];
tap.numberOfTapsRequired = 1;
_player.scalingMode = 2;
[_player prepareToPlay];
[_player shouldAutoplay];
}
- (void)handleTap:(UITapGestureRecognizer *)gesture {
// ControlStyle changed to ShowEmbedded
_player.controlStyle = 1;
}
I have added the tap recogniser in the view of the player area, it should show but sadly it does not. I have added the super viewDidLoad in my actual code. That is not the problem.
Make a button. When the button is tapped, the video should be paused. Then change the control style within. The user then has to click the to see the controls.
- (IBAction)showControls:(id)sender {
[_player pause];
_player.controlStyle = MPMovieControlStyleEmbedded;
}

I am having a difficult time getting a Swipe Gesture Recognizer to work on my app. Here is the Hierarchy of it all.
App's root view is a UINavigationController which has class ViewController as visible for the first view seen. I have a UIButton which will fire a movie that loops until I tap it twice which will have the navigation controller push a new ViewController that I have made called PUPPETS1 onto the screen. This VC has its own xib. The xib has a UIImageView. What I want to have happen is to start playing a movie once I swipe up on the screen, but that never happens, and the console never shows my NSLog from the 2nd VC's method.
- (void)loopVideo {
NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"warpspeed" withExtension:#"mov"];
UIView *patternView = [[UIView alloc] initWithFrame:self.view.bounds];
patternView.backgroundColor = [UIColor blackColor];
[self.moviePlayer2.backgroundView addSubview:patternView];
self.moviePlayer2 = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[self.moviePlayer2 setControlStyle:MPMovieControlStyleDefault];
self.moviePlayer2.controlStyle = MPMovieControlStyleNone;
self.moviePlayer2.scalingMode = MPMovieScalingModeAspectFill;
self.moviePlayer2.movieSourceType = MPMovieSourceTypeFile;
[self.moviePlayer2 setAllowsAirPlay:YES];
self.moviePlayer2.view.frame = self.view.frame;
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(puppetOne)];
tapGesture.numberOfTapsRequired = 2;
tapGesture.numberOfTouchesRequired = 1;
UIView *aView = [[UIView alloc] initWithFrame:self.moviePlayer2.backgroundView.bounds];
[aView addGestureRecognizer:tapGesture];
[self.view.window addSubview:aView];
[self.view addSubview:self.moviePlayer2.view];
self.moviePlayer2.repeatMode = MPMovieRepeatModeOne;
[self.moviePlayer2 play];
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
In the 2nd VC, the PUPPETS1 one:
- (void)viewDidLoad {
[super viewWillAppear:YES];
UISwipeGestureRecognizer * swipeRec = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(playPuppets)];
swipeRec.direction = UISwipeGestureRecognizerDirectionUp;
UIView *aView2 = [[UIView alloc] initWithFrame:self.view.bounds];
[aView2 addGestureRecognizer:swipeRec];
[self.view addSubview:aView2];
// Do any additional setup after loading the view from its nib.
}
-(void)playPuppets {
NSLog(#"PLAYING");
NSURL *videoURL = [[NSBundle mainBundle] URLForResource:#"SundayPuppets" withExtension:#"m4v"];
//filePath may be from the Bundle or from the Saved file Directory, it is just the path for the video
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
//[playerViewController.player play];//Used to Play On start
[self presentViewController:playerViewController animated:YES completion:nil];
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
The frame of the view to which you're attaching the gr depends on it's parent view's bounds, and those aren't initialized yet in viewDidLoad.
Move the setup to after layout is complete (and tweak it to run just once, on the first layout change), i.e.
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
UIView *swipeView = [self.view viewWithTag:999];
// only do this if we haven't done it already
if (!swipeView) {
// now that self.view.bounds is initialized...
swipeView = [[UIView alloc] initWithFrame:self.view.bounds];
swipeView.tag = 999;
// the rest of your OP setup code is fine, and goes here
UISwipeGestureRecognizer * swipeRec = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(playPuppets)];
swipeRec.direction = UISwipeGestureRecognizerDirectionUp;
[swipeView addGestureRecognizer:swipeRec];
[self.view addSubview:swipeView];
NSLog(#"%#", swipeView);
}
}
EDIT The code above attached the gesture recognizing view correctly, providing a fix in the second view controller. It turns out that the other problem was the previous view controller was not properly removing the (deprecated) MPMoviePlayer, resulting in touches not functioning on the pushed vc. The entire reworked ViewController.m can be found in the chat linked below, but the fix for the touches issue was here...
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.moviePlayer stop];
[self.moviePlayer.view removeFromSuperview];
self.moviePlayer = nil;
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
My scenario is that there will be many sub views in the main view and tapping on each sub view should generate different result.
My approach is for each sub view to implement its own tap recognizer, instead of for the main view to have one single tap recognizer and calculate the which sub view's area the user has tapped in. Is this a correct and viable approach?
I have tried this approach but it doesn't seem to work. The tap method never gets called. I read lots of articles on stackoverflow but they didn't seem to help.
For example, although the sub view is not an image view I still manually set its userInteractionEnabled property to YES, as some posts suggested. But that didn't help.
Below is the main code of the sub view:
- (void) handleOneTap:(UITapGestureRecognizer*)paramSender{
// *** Never gets called
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));
}
}
- (void)viewDidLoad {
[super viewDidLoad];
_container = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 280, 300)];
[self.view addSubview:_container];
_container.backgroundColor = [UIColor redColor];
_container.opaque = YES;
// setup tap recognizer
self.tapGestureRecognizer = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(handleOneTap:)];
self.tapGestureRecognizer.numberOfTouchesRequired = 1;
self.tapGestureRecognizer.numberOfTapsRequired = 1;
self.view.userInteractionEnabled = YES;
self.container.userInteractionEnabled = YES;
[self.view addGestureRecognizer:self.tapGestureRecognizer];
}
Any help will be appreciated.
If you want to add UIGestureRecognizer to your subview, you should do it like that:
_container = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 280, 300)];
[self.view addSubview:_container];
_container.backgroundColor = [UIColor redColor];
_container.opaque = YES;
_container.userInteractionEnabled = YES;
self.tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleOneTap:)];
self.tapGestureRecognizer.numberOfTouchesRequired = 1;
self.tapGestureRecognizer.numberOfTapsRequired = 1;
self.view.userInteractionEnabled = YES;
[_container addGestureRecognizer:self.tapGestureRecognizer];
It looks like that problem is not in UITapGestureRecognizer, but in case how you add Subview from ViewController.
Right way to add subviewcontoller is:
SSubViewController *pvc = [SSubViewController controllerWithSubViewID:0];
[self.view addSubview:pvc.view];
[self addChildViewController:pvc];
Do it in your ViewController and it should solve your problem
I have code like this..
in loadView()
I have created the scrollview like this with no.of taps and max value
self.scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
self.scrollView.delegate = self;
self.scrollView.maximumZoomScale = 2;
self.scrollView.autoresizingMask = self.view.autoresizingMask;
[self.view addSubview:self.scrollView];
UITapGestureRecognizer *tapOnce = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleDoubleTap:)];
[tapOnce setNumberOfTouchesRequired:1];
[doubleTap setNumberOfTapsRequired:2];
[tapOnce requireGestureRecognizerToFail:doubleTap];
[self.scrollView addGestureRecognizer:tapOnce];
[self.scrollView addGestureRecognizer:doubleTap];
Method implementation:
- (void) handleSingleTap:(UIGestureRecognizer *)gestureRecognizer
{
//single tap in full screen mode it will dismiss the view
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer
{
//double tap will zoom the view to scrollview max value
[self.scrollView setZoomScale:self.scrollView.maximumZoomScale animated:NO];
}
Now I am able to "zoom" on tapping to full screen image and it will go in maxZoom value, but how to come back from zoomed to min value on double tap on the same, because I have functionality to dismiss the view on single tap. I need to handle one more double tap in the "handledoubleTap" method itself.
- (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer
{
if ( flag == 1 ){
flag = 0;
[self.scrollView setZoomScale:self.scrollView.maximumZoomScale animated:NO];
}
else {
flag = 1;
[self.scrollView setZoomScale:self.scrollView.minimumZoomScale animated:NO];
}
}
In the above method just set flag according to your need. Hope this helps.. :)
I have a UIScrollView and inside this I have UILabels. I need to detect touch events for the UILabels. At the moment, it is detecting the touch inside the second label only. It ignores the first.
I have the code -
Creating the UIScrollView
backGroundView = [[UIScrollView alloc] init];
backGroundView.frame= self.view.frame;
backGroundView.userInteractionEnabled = YES;
[backGroundView setScrollEnabled:YES];
backGroundView.showsVerticalScrollIndicator = YES;
backGroundView.contentSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height);
backGroundView.delegate = self;
[self.view addSubview:backGroundView];
Creating the UILabel
UILabel *OneDay = [[UILabel alloc] initWithFrame:CGRectMake(15, stockChart.bounds.origin.y + stockChart.bounds.size.height + 35, 40, 30)];
OneDay.text = #"1d";
OneDay.tag = 1;
OneDay.userInteractionEnabled = YES;
OneDay.layer.borderColor = [UIColor grayColor].CGColor;
OneDay.layer.borderWidth = 1.0f;
OneDay.textAlignment = UITextAlignmentCenter;
[OneDay addGestureRecognizer:detectTimeFrameChange];
[backGroundView addSubview:OneDay];
UILabel *FiveDay = [[UILabel alloc] initWithFrame:CGRectMake(45, stockChart.bounds.origin.y + stockChart.bounds.size.height + 35, 40, 30)];
FiveDay.text = #"5d";
FiveDay.tag = 2;
FiveDay.userInteractionEnabled = YES;
FiveDay.layer.borderColor = [UIColor grayColor].CGColor;
FiveDay.layer.borderWidth = 1.0f;
FiveDay.textAlignment = UITextAlignmentCenter;
[FiveDay addGestureRecognizer:detectTimeFrameChange];
[backGroundView addSubview:FiveDay];
Creating the gesturerecognizer
UITapGestureRecognizer *detectTimeFrameChange = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(timeFrameLabelTapped:)];
detectTimeFrameChange.numberOfTapsRequired = 1;
[backGroundView addGestureRecognizer:detectTimeFrameChange];
Handling gesture
-(void)timeFrameLabelTapped:(UITapGestureRecognizer*)recognizer{
if (recognizer.view.tag == 1) {
NSLog(#"One pressed");
}
else if (recognizer.view.tag == 2){
NSLog(#"2 pressed");
}
}
You can use this :
UITapGestureRecognizer *labelTap=[[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(labelTapped)];
labelTap.numberOfTapsRequired=1;
[yourLabel addGestureRecognizer:labelTap];
handle the touch tap event inside labelTapped method:
-(void)labelTapped
{
//your code to handle tap
}
Touch events are not detected on UIScrollview for getting your requirement add tap gestures to your label.
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(singleTapGestureCaptured)];
[OneDay addGestureRecognizer:singleTap];
-(void)singleTapGestureCaptured{
NSLog(#"touch detected");
}
You can find using tapgesturerecogniser like that...
UITapGestureRecognizer *singleFingerTap =
[[UITapGestureRecognizer alloc] initWithTarget:self
action:#selector(handleSingleTap:)];
[self.scrollview addGestureRecognizer:singleFingerTap];
//The event handling method
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
if(recognizer.view.tag == 1){}
//Do stuff here...
}
Where have you written the touchesBegan?
If you want to detect the touches in the label you'll have to create a subclass of label and write your touchesBegan there to detect the touch events
The problem here is that you are trying to use the same gesture recognizer for multiple views. A gesture recognizer can only be attached to a single view at once. You are only receiving events from the last view, because that is the view the recognizer is currently attached to. To fix the issue, simply create a gesture recognizer for each view you want to detect touches in.
I´m trying to use UITapGestureRecognizer in order to handle the taps on my fullscreen video. If I omit [self.player setFullscreen:YES animated:NO]; it works, but then my video won't scale to fit the screen.
From my .m:
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *videoPath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"mov"];
player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:videoPath]];
player.shouldAutoplay = NO;
player.view.frame = self.view.bounds;
player.scalingMode = MPMovieScalingModeAspectFit;
player.controlStyle = MPMovieControlStyleNone;
player.fullscreen = YES;
self.player = player;
[self.player prepareToPlay];
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTap:)];
UIView *aView = [[UIView alloc] initWithFrame:player.view.bounds];
[aView addGestureRecognizer:tapGesture];
[self.player.view addSubview:aView];
}
- (IBAction)playMovie:(id)sender {
//add the MPMoviePlayerViewController to this view (as subview)
//Play movie
[self.view addSubview:self.player.view];
[self.player setFullscreen:YES animated:NO]; //commenting out this will make it work
[self.player play];
}
- (void)handleTap:(UITapGestureRecognizer *)recognizer {
NSLog(#"tap tap");
}
From my .h:
#property (retain, nonatomic) MPMoviePlayerController *player;
- (void)handleTap:(UITapGestureRecognizer *)recognizer;
You can try this:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willEnterFullScreen:)
name:MPMoviePlayerWillEnterFullscreenNotification
object:nil];
- (void)willEnterFullScreen:(NSNotification*)notification
{
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTap:)];
UIView *aView = [[UIView alloc] initWithFrame:self.player.backgroundView.bounds];
[aView addGestureRecognizer:tapGesture];
[self.view.window addSubview:aView];
}
and then remove your subview when MPMoviePlayerWillExitFullscreenNotification is posted
In my comment, I drafted how to get that covered when using proper fullscreen ([self.player setFullscreen:YES animated:NO];).
I would suggest that instead you simply resize the player view to cover the entire screen by setting its frame accordingly.
You initialising code would have to get rid of that player.fullscreen = YES;, but that I guess is obvious by now.
