編譯器出錯的問題：
1.?Unsupported compiler 'com.apple.compilers.llvmgcc42' selected for architecture 'armv7'
解決方法：
Change your compiler for C/C++/ObjectiveC Go to Build Settings->Build OPtions->compiler for C/C++/ObjectiveC; select Default(Apple LLVM5.0)
2. Assertion failure in -[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3491.2.5/UIApplication.m:3173
報錯內(nèi)容
如果還有報錯在AppDelegate中
didFinishLaunchingWithOptions
定義一個空UIViewController即可，添加如下代碼解決：
UIViewController *emptyView = [[UIViewController alloc ]initWithNibName:nil bundle:nil];
self. window .rootViewController = emptyView;
