问题 I am creating multiple custom UIView's in a custom UIView . The creation of the custom sub-views is ok. They look like this: The draw method is quite straightforward: [[UIColor brownColor] set]; CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(ctx, 5.0f); CGContextBeginPath(ctx); CGContextMoveToPoint(ctx, 0.0f, 0.0f); CGContextAddLineToPoint(ctx, 100.0f, 0.0); CGContextAddLineToPoint(ctx, 130.0f, 25.0f); CGContextAddLineToPoint(ctx, 100.0f, 50.0f);

UIScrollView does not work with EXC_BAD_ACCESS

问题 I have a scrollview that is subview of view, and has the subviews. The problem is this: the scrollView came with the black background (as I have set transparent) and also does not work. The scrollView is connected with an IBOutlet . I redid the XIB 2 times, what needs fixing? When I add the scrollView as subview of view: [self.view addSubview:self.scrollView]; I get this error during runtime: 0x132b61: calll 0x132b66; CA::Layer::ensure_transaction_recursively(CA::Transaction*) + 14 EXC_BAD

How to disable “highlight subviews” message for UIView/UIViewController in iOS SDK?

由 痴心易碎 提交于 2019-12-04 08:31:32

However, I do not want custom subviews (and their subviews) to receive the message to update their highlighted states and therefore disrupt the backgroundColor property. Edit By "subview" I mean any UIView subclass, not just UITableViewCell s. Perhaps this hypothetical situation will better articulate what I'm looking for : I have one UITableViewCell . Call it c . I then add one UIView (call it v ) as a subview of c .

问题 How do I remove all of the subviews from a UIScrollview? 回答1: Let scrollView be an instance of UIScrollView . In Objective-C, it's pretty easy. Just call makeObjectsPerformSelector: , like so: Objective-C: [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; In Swift, you don't get that runtime access, so you have to actually handle the iteration yourself.
