由 允我心安 提交于 2019-12-10 11:39:53
问题 I need to add some tapGestures to some part of a text, thats in a UILabel. It seems to be able to make a hyperlink - so I guess its possible to make a functioncall as well, but I'm just not sure how to do it. Heres my code: let regularFont = UIFont(name: Constants.robotoRegular, size: 13)! let att1 = [NSFontAttributeName: regularFont] let turqoiseFont = UIFont(name: Constants.robotoBold, size: 13)! let att2 = [NSFontAttributeName: turqoiseFont] let attString1 = NSMutableAttributedString

问题 I am trying to handle tableViewCell's being tapped, but the problem is that this is a "temporary tableView". I have it coded so that it will appear while the user is editing a UITextField, but then I set up a gesture recognizer to set the tableview to hidden as soon as the user clicks somewhere away from the UITextField. I have the gesture recognizer set up as follows: UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)]; [tap

touchesBegan with delay

由 梦想的初衷 提交于 2019-12-08 20:08:48
问题 I have a subclass of UIView , and added the touchesBegan and touchesEnd methods... In touchesBegan , I set the backgroundColor from white to green by using self.backgroundColor = [UIColor greenColor] ... in the touchesEnd I reset the color to white. It works but very slowly. By tapping the view, it takes 0.5 - 1.0 sec until I see the green color. Selecting a cell in a UITableView it's much faster. 回答1: Try this: self.view.userInteractionEnabled = YES; UILongPressGestureRecognizer *recognizer

Losing tap recognition after adding a UIScrollView under a UIButton

问题 I have two adjacent UIScrollViews, both partially covered by a UIButton with a tap gesture recognizer. They are added to the view in this order: Scrollview #1 Button Scrollview #2 (added by user interaction) Both scrollviews are z-positioned "behind" the button, but the button does not receive taps where it overlaps with the newer scrollview. Is there a way I can declare "keep this button the topmost receiver of taps"? EDIT: Below is a mockup of the views. The red part of the button is the

how to add double tap gesture to UITextView

由 一世执手 提交于 2019-12-07 07:30:36
问题 currently I want to let UITextView to have a double tap gesture. It seems UITableView has its own double tap gesture, when we double tapped, some text will be selected. So I want to remove this default double tap gesture to my own gesture recognizer. I tried many methods, and all failed. It seems there's no way to remove the default recognizer of UITextView. I also want to add a transparent view on this UITextView to do double tap event, but this subview will block other gestures on
