问题 I have an ipad application that I would like to run on iPad pro, but when I run it, it only occupies one corner of the screen like so: Now, another stackoverflow question asked the same question and the response was to remove the launch screen file and not to give the OS any hardcoded information about the device size it's going to run on.

问题 I am having trouble getting Xcode 8 with Swift 3 to auto-complete common initialization methods, and was wondering if there is anything I could do to fix the situation. Specifically, take something like: let jsonString = String(data: jsonData, encoding: .utf8) The initialization method String(data:, encoding:) will not populate. Demo Video 回答1: I find it useful to type the actual word .init before asking for code completion. Then later, I take it back out again. Note that Xcode is very choosy

In situations where it is necessary to capture a dynamic string, you may explicitly

问题 I just updated my Xcode ver from 7.3 to 8.0 and some buttons borders disappeared. The code looks fine, so I really don't know what happened to the layers. btw - in some other controllers I can see the layers borders. self.button.layer.borderColor = borderColor.CGColor; self.button.layer.borderWidth = 2; self.button.layer.cornerRadius = CGRectGetHeight(self.button.frame) / 2; before: (The image is only for example - the borders looks different at real time) now: 回答1: The reason is that XCode 8
