用github导入EaseUI找不到这句话

文档上说导入成功后写入这句话：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [[EaseSDKHelper shareHelper] easemobApplication:application didFinishLaunchingWithOptions:launchOptions appkey:@"douser#istore" apnsCertName:@"istore_dev" otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}]; return YES; }
但是kSDKConfigEnableConsoleLogger没有找到，求解
