IOS Reachability判斷所請求伺服器是否逾時？

開發Web等網路應用程式的時候，需要確認網路環境，串連情況等資訊。如果沒有處理它們，是不會通過Apple的審查的。

Apple 的 常式 Reachability 中介紹了取得/檢測網路狀態的方法。

1.在你的程式中使用 Reachability 只須將該常式中的 Reachability.h 和 Reachability.m 拷貝到你的工程中。

2.然後將 SystemConfiguration.framework 添加進工程。

 

我使用的版本為 : Version: 2.2

我為Apple的常式增加了一個全域 -- ReachabilityAutoChecker

.h

*

 

.m檔案

+ ( ReachabilityAutoChecker *staticChecker = (!===- ()reachabilityChanged:(NSNotification** curReach = [note ==

 

我為Apple的常式增加了一個Category -- Reachability (AutoChecker)

.h檔案:

+ ()startCheckWithReachability:(Reachability *+

 

.m檔案:

+ ()startCheckWithReachability:(Reachability **checker ===+*checker = (!=(networkStatus ==(networkStatus ==== kShouldPrintReachabilityFlags                

 

調用方式:

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *    Reachability *pReachability = [Reachability reachabilityWithHostName:=    self.viewController = [[ViewController alloc] initWithNibName:=

 

ViewController.m

- (IBAction)upInside_checkNetStatus:((!*alert = [[UIAlertView alloc] initWithTitle:                                                       

 

運行時提醒下 :  #error "此類需要在非arc環境下編譯，請添加-fno-objc-arc標記"
