It was achieved in the end by adding these two lines to this section - (void)drawRect:(CGRect)rect { [[UIColor redColor]setStroke]; // Added these [[UIColor redColor]setFill]; // two lines [incrementalImage drawInRect:rect]; [path stroke]; } ...
UITouch is not working with ios8
ios,uigesturerecognizer,uitouch,xcode6.1,ios8.1
Thanks for all your answers. I got solution by moving irate code from +initialize method of AppDelegate to didFinishLaunchingWithOptions method. My iRate get initialized and configure but don't show popup. May be that's why i was not able to perform any touch on screen.
iOS do not forward touches to views below
You can subclass UIScrollView and add this method to the new class - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView *result = [super hitTest:point withEvent:event] ; self.scrollEnabled = ![result isKindOfClass:[UISlider class]] ; return result ; } ...

New in iOS 8.0 is the majorRadius property of UITouch that should give you the data you need: Use the value in this property to determine the size of the touch that was reported by the hardware. This value is an approximation of the size and can vary by the...
iOS: How to Detect subview position around view
ios,objective-c,uiview,uilabel,uitouch
I believe you want to use this method: [self.view convertRect:self.label.frame fromView:self.view.subview]; from this post: How to get the frame of a view inside another view? This will give you the adjusted position of the label form your list of 1000+ labels. You can then compare that to the label of...
How to allow users to draw throughout my app?
I modified your code a little, because I was getting that same error that you mention in your comment. This code worked for me. @interface RDImageView () @property (nonatomic) CGPoint pointCurrent; @end @implementation RDImageView -(instancetype)initWithCoder:(NSCoder *)aDecoder { if (self = [super initWithCoder:aDecoder]) { self.userInteractionEnabled = YES; self.backgroundColor = [UIColor blueColor];...
Ignore gestures on parent view
objective-c,subview,uitouch,superview
If you are looking for a better solution, you can use gestureRecognizer:shouldReceiveTouch: delegate method to ignore the touch for the parent view recognizer. - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{ UIView* swipeableSubview = ...; //set to the subview that can be swiped CGPoint locationInSubview = [touch locationInView:swipeableSubview]; BOOL touchIsInSubview = [swipeableSubview pointInside:locationInSubview...
UIPanGestureRecognizer: detect touch location at end of swipe
ios,uitouch,uipangesturerecognizer,uiswipegesturerecognizer
Have a look at UIGestureRecognizerState. That is what you need. Sample code (assumption here being, you only need the touch point when the user finishes panning i.e. lifts his finger): -(void)swipedRight:(UIPanGestureRecognizer *)panGesture { if ([panGesture state] == UIGestureRecognizerStateEnded) { //User touch has ended CGPoint touchUpPoint = [panGesture translationInView:self.view]; // or...

Getting the pointer from a touch event
I assume you have that long list of pointers and information in string format, so to obtain just the "0x7b657920" you could just do something like: var str = descriptionString //The info from the touch event let rangeOfPointer = Range(start: advance(str.startIndex, 10), end: advance(str.startIndex, 20)) let pointerStr = str.substringWithRange(rangeOfPointer) Hope...
Forward/pass through UIGesture (swipe) to sibling view
objective-c,uiscrollview,uigesturerecognizer,uitouch,uiswipegesturerecognizer
I've found a solution for this issue. While I was unable to forward the swipe up/down gestures to the image views behind the scrollview, I've now added gesture recognisers with direction up/down to the scrollview. In the gesture recognisers actions, I determine the point of the gesture within the window...
Is there a pointer for each touch point in ios
Not really for each point, but for each touch. To access them requires your own touch handling, for example in the UIView where the touches occur or its ViewController. This simply requires you to write your own methods for touchesBegan:withEvent:, touchesMoved:withEvent: and touchesEnded:withEvent:. When touchesBegan:withEvent:, touchesMoved:withEvent: and touchesEnded:withEvent: are called...
