禁用互聯網連接時的按鈕

Question

當iOS中沒有連接到網絡/互聯網時，如何禁用按鈕？

Answer 1

檢查Apple的可訪問性代碼。

http://developer.apple.com/library/ios/#samplecode/Reachability/Introduction/Intro.html

，並使用它像這樣：

Reachability *reachabilityInstance = [[Reachability reachabilityForInternetConnection] retain]; 
[reachabilityInstance startNotifier]; 
NetworkStatus networkStatus = [reachabilityInstance currentReachabilityStatus]; 
BOOL connected = (networkStatus==ReachableViaWiFi || networkStatus==ReachableViaWWAN); 

Answer 2

你可以簡單地隱藏按鈕，每當你需要

[button setHidden:YES];
