今天上午把iPad mini升级到了iOS 8.0，升级提示需要6.7G空间，无奈只好把一些大的App删掉腾冲空间，然后开始升级，3小时后终于升级成功了。
下午试着把我们的App通过xcode 5 安装到升级到iOS8.0的iPad，结果不能识别设备了，于是到开发者中心下载最新的xcode6.0.1, 针对OS X 10.9.4系统的。注意：
Xcode 6 introduces a radically new way to design and build software. Swift is an innovative new programming language for Cocoa and Cocoa Touch and, when combined with Xcode tools, makes programming a delightfully live experience. This same live experience permeates throughout Xcode 6. Live rendering within Interface Builder displays your hand-written UI code within the design canvas, instantly reflecting changes you type in code. And the new view debugger explodes all the UI layers into a 3D visualization, making it easy to understand how your interface is composed, and identify overlapping or clipping views.
