Hello all, I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the but...
I know that this is a very commonly asked question, but all of the answers on every website don't work! If you still don't know what I mean, then maybe this line of code will help you understand. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location...
I am trying to recreate the selection behaviour as seen in the built in iPhone Voice Memo App. That is, in the voice memo list view, when the user selects an item, and there is already another item selected, the touch down doesn't select the cell immediately, but on touch up the previously selected cell is deselected and the new cell is...
Hi Everyone, Is there a way to increase the frequency calls of touchesMoved than the default? I need more calls of it to draw a smooth circle. It gets called not too frequent by default and so I get an edgy circle. Is there a way to tweek the frequency of touchesMoved calls? Thanks ...
If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Update It has som...
I am trying to create a new method within my TapDetectingImageView file and it's giving me a warning that it cannot find the method even though I have it declared in the .h file. The specific three warnings all point to the @end line in the .m file when I build it and they say: "Incomplete implementation of class 'TapDetectingImageView'...
I have created a few UIImageViews programmatically, but I have a feeling that even though I setMultipleTouchEnabled to YES during the setup, it is not getting set properly and it's leading to multi-touch issues. My question is, within touchesBegan how do I go about asking the UIImageView that was touched if it has MultipleTouchEnabled o...
I'm developing a multitouch application. One touch is expected to move, and I need to track its position. For all other touches, I need to track their beginnings and endings, but their movement is less critical. Sometimes, when 3 or more touches are active, my UIView does not receive touchesMoved: events for the moving touch. This probl...
Hey Guys! Thanks so much for reading! - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; CGPoint location = [[CCDirector sharedDirector] convertToGL: [touch locationInView:touch.view]]; CGRect myRect = CGRectMake(100, 120, 75, 113); int tjx = sprite.position.x; ...
I'm working on my first iPhone application, and I'm getting some very strange behavior when I try to implement touch events. I set up touchesBegan:withEvent: and its sister methods under a subclass of UIViewController, but they aren't registering. What's even weirder is that when I try using touches on the simulator while running the c...
Hi, I have a UIView (mainview), including 50 UIImageViews (image1 .. 50)) (all are set to clickable (UIVIEW and also UIImageViews) Now to test if one of my images is touched I do in 'touchesbegan': touch = [[event allTouches] anyObject]; if ([touch view] == image1) { NSLog (@"image1 clicked"); } But when i test on if my "mainview...
This question is a follow on from the following: http://stackoverflow.com/questions/3235967/uitouch-event-not-responding I done more research and I know what the problem is, but I don't know how to solve it or even if it can be solved. I may have to take a new approach. I have a RootViewController and from this I load a second ViewCon...

Im having a little problem on handling touches in my apps. I set my touchesBegan like this: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *currentTouch = [[event allTouches] anyObject]; touchPoint = [currentTouch locationInView:self.view]; if (CGRectContainsPoint(image1.frame, touchPoint)) { ...
Hi, Is there a way to know if the hitTest:withEvent: method is being thrown because of a touchesBegan, touchesMoved or touchesEnded event? by now I only do: if([event type]==UIEventTypeTouches) { } but this is not exclusive enough ...
I have a UIView subclass with several subviews and I want to handle these events in the class: touchesBegan:withEvent: touchesMoved:withEvent: touchesEnded:withEvent: but I also want these event to be called at the subviews. How can I accomplish that? (I have already tried with hitTest, but I only get the touchesBegan event and no t...
Hello, i want to receive the changed distance of two touches in my program after "pinching". First, i start with the touchesBegan: - (CGFloat)distanceBetweenTwoPoints:(CGPoint)fromPoint toPoint:(CGPoint)toPoint { float x = toPoint.x - fromPoint.x; float y = toPoint.y - fromPoint.y; return sqrt(x * x + y * y); } - (void)touchesBe...
