问题 This question already has answers here : UIButton's Selected State not working in iOS7 (3 answers) Closed 5 years ago . Today I upgraded my iPhone OS to iOS 7.1 . Everything looks good in the new iOS, but I have a critical issue regarding UIButtons in the app I'm working on. The selected state was gone in every button. For instance, Like button has title of "Liked" when selected but it's not shown at all when selected right now. Buttons have only text without background/image in every state.

Using PDFs for icon images in Xcode 7.2

由 情到浓时终转凉″ 提交于 2020-01-03 14:16:09
问题 I'm attempting to use PDF files as icons in an app I'm working on. The issue I'm encountering is I'm getting inconsistent tint colors. If I set a button image from interface builder, the icon image shows up black at runtime. Every time. Regardless of what I attempt to set from interface builder. I tried setting my button icon image via code and instead of showing up black , it's white : let myGraphicFile = UIImage(named: "myPDFImage") let myButtonImage = myGraphicFile?.imageWithRenderingMode

UIButton action is not triggered after constraint layouts changed

由 南楼画角 提交于 2020-01-03 08:42:13
问题 I have got an UIButton on a storyboard ViewController. When I load data into the form and the layout is significantly changing the button does not recognise the touch action. I have figured out that when button is visible on the scrollview right after it if filled with data, the touch action works. If the data too long and the button is not visible at first, just when it is scrolled into the display, the touch action does not work. I was checking if something is above the button, but nothing.

Cancel touch on UIButton on touch move (iOS)

由 拥有回忆 提交于 2020-01-03 05:37:08
问题 I have a view with button and touch-move gesture. When user touches button it becomes selected and keeps receiving touch-move events. I want to deselect the button on touch-move and pass moves to gesture. How to cancel touch receiving on button "elegantly"? 回答1: You need to implement the UIGestureRecognizerDelegate. Specifically this method. Then just build your logic for deciding if the gesture should receive the touch or not. If you return NO then the touch is up for grabs for the button.
