推荐答案

在您的 didFinishLaunchingWithOptions 方法的第一行

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 [YourSingletonClass class]; // ADD THIS LINE

它将触发初始化在您的单例类中进行方法初始化

it will trigger initialize method initialization in your singleton class

+ (void) initialize {
     _innerInstance = [[YourSingletonClass alloc] init];
}
