问题 I'm using UITapGestureRecognizer because I'm using a UIScrollView that acts as a container for my UILabel s. Basically I'm trying to use an action method with arguments so I can e.g. send myLabel.tag value to the action method to know what action to take depending on what UILabel has has been triggered by a tap. One way of doing it is having as many action methods as UILabel s but that isn't very "pretty" codewise. What I would like to achieve is just having one action method with switch

问题 I'm trying to add in my app the possibility to dismiss the keyboard when the user taps somewhere else out of the text fields. I'm implementing this functionality using UITapGestureRecognizer. I create a new UITapGestureRecognizer object using the Unrecognized selector with UITapGestureRecognizer(target: Any?, action: Selector?) and set the action parameter to a function that resigns the first responder of both the text fields I'm using in this view.

问题 In my class I have 11 UITapGestureRecognizers in an array textViewRecognizer attached to 11 out of 100 UITextFields in an array boxArray. When a Textfield is tapped containing a UIGestureRecognizer it runs tappedTextView where I try to get the index of the first responder. However, due to some weird ordering in how things are executed, the action function only gives me the first responder of the previous first responder to the one that was just tapped. Also, I have to double tap to even

问题 Could someone please help me recognise a tap when a user taps on the Title in the Navigation Bar ? I would like to recognise this tap and then animate the tableHeaderView appearing. Possibly sliding the TableView down. The idea being that the user can then select a quick option (from the tableViewHeader) to re-populate the TableView. However I cannot recognise any taps.
