implementing Custom UIView Rendering and Hit Testing in Objective-C
I'm not sure how to approach I'm relatively new to this, so bear with me. I'm currently working with a question with a custom UIView subclass where the rendering seems to be fine, but the hit testing behaves unexpectedly. I've overridden the `hitTest:withEvent:` method to allow for certain touchable areas, but it's not behaving as expected. When I tap on a part of the view that should respond to touches, I sometimes get no response or the touches get passed to the parent view instead. Here's the relevant code for my custom view: ```objective-c @interface CustomView : UIView @end @implementation CustomView - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { // Define a custom touchable area CGRect touchableArea = CGRectMake(10, 10, 200, 200); if (CGRectContainsPoint(touchableArea, point)) { return self; // Return self if within the touchable area } return [super hitTest:point withEvent:event]; // Pass to super otherwise } - (void)drawRect:(CGRect)rect { [[UIColor blueColor] setFill]; UIRectFill(rect); } @end ``` The scenario arises particularly when the `CustomView` is added as a subview to another UIView. I noticed that touches are sometimes registered by the parent view instead, even when I tap within the defined `touchableArea`. I'm using iOS 15.0 and Xcode 13.0. I've also tried adding an explicit gesture recognizer to see if that resolves the scenario: ```objective-c UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; [self addGestureRecognizer:tapRecognizer]; ``` However, the recognizer doesn't seem to react when tapping in the custom area. Any insights on why the hit testing might not be working as expected? Are there specific cases in which hit testing does not behave as anticipated that I should be aware of? Thanks in advance for your help! I appreciate any insights! This issue appeared after updating to Objective-C latest. I appreciate any insights! This is part of a larger service I'm building. Is this even possible?
