问题 I've encountered a coding error for my flappy bird project, in Xcode 6.1. The code is to allow rotation of the bird, and it reads: bird.zRotation = self.acotarMinMax(-1, max: 0.3, valor: bird.physicsBody?.velocity.dy * (bird.physicsBody?.velocity.dy < 0 ? 0.003 : 0.001)) the error occurs under dy , it reads: value of optional type 'CGFloat?' not unwrapped; did you mean to use '!' or '?'?

Edit1: Edit2: Here is what I did to get things to display correctly: I had to drag the edges of the WebView all the way

问题 This is an extension of this thread regarding displaying status bar for iOS8. Unfortunately, I needed to enable my apps to display the status bar on landscape orientation regardless of fixed or rotated. With my answer on this thread, the behaviour on the iPhone6 Simulator (not sure on actual device for now) the status bar doesn't get displayed. Yet when the application is resumed from other application or home screen it gets displayed. Is this normal? 回答1: No that is not normal, however you
