cocoapods 配置文件添加：

#防止值为空导致的crash
pod 'LSSafeProtector'

appdelegate.m文件配置:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    ////开启防止奔溃
    //    IsDebug=YES代表开发环境  捕捉到崩溃 ，会打印崩溃信息，同时利用断言闪退，会回调block
    //    IsDebug=NO，代表线上环境，拦截到崩溃不打印崩溃信息，也不会断言闪退，会回调block
    [LSSafeProtector openSafeProtectorWithIsDebug:NO block:^(NSException *exception, LSSafeProtectorCrashType crashType) {
        //[Bugly reportException:exception];
        DEBUGLOG(@"%@",exception);
    }];
