在友盟官網可以看到相應的步驟，申請appkey，導入SDK，然后在AppDelegate里面寫入相應的代碼，下面就是關鍵的代碼：
實現頁面的統計需要在每個UIViewController中配對調用如下方法：
- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [MobClick beginLogPageView:@"PageOne"];//("PageOne"為頁面名稱，可自定義) }- (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [MobClick endLogPageView:@"PageOne"]; }幾年之前做過這個，那時候才剛開始做iOS，就按照這個文檔在每一個UIViewController里面寫了這個方法，現在看來真是太low了。
這次又做這個友盟統計，就想起來用runtime解決這個問題。
在工程中創建一個UIViewController的Category，然后通過Runtime動態添加兩個方法，分別替代viewWillAppear和viewWillDisappear方法。這樣就不需要在每一個 UIViewController寫這段代碼了。
