问题 Just wondering how you are supposed to stretch the iAdBannerView across the full width of the Adaptive Layout Storyboard that exists in Xcode 6. When I try and stretch it to the corners (so I can set auto layout values), it does allow it to be stretched. 回答1: Your ADBannerView will know which device it is on and set its dimensions correctly. You should just let auto layout know where you want the ad to be. For example, if you wanted the ADBannerView to be at the bottom of the screen then pin

iOS 8 presentationController determine if really is popover

阅读更多关于 iOS 8 presentationController determine if really is popover

问题 I'm using the new adaptive "Present As Popover" capability of iOS 8. I wired up a simple segue in the StoryBoard to do the presentation. It works great on an iPhone 6 Plus as it presents the view as a popover and on an iPhone 4s it shows as a full screen view (sheet style). The problem is when shown as a full screen view, I need to add a "Done" button to the view so dismissViewControllerAnimated can be called. And I don't want to show the "done" button when it's shown as a popover. I tried

iOS Prevent timer UILabel 'shaking' when numbers change

阅读更多关于 iOS Prevent timer UILabel 'shaking' when numbers change

问题 I have a UILabel which shows the output of a timer in the format MM:ss:SS (minutes, seconds, centiseconds), however it "shakes" from left to right as the width of the centiseconds changes - "11" is narrower than "33" for example. Is there any way I can mitigate this? I've tried centring it, giving it a fixed width but they haven't seemed to help. 回答1: Since iOS 9.0, the system font uses proportional digits. If you want monospaced digits, there's a variant font which you can obtain using +
