没有互联网连接时禁用按钮

Question

如果在iOS中没有连接到网络/互联网时，如何禁用按钮？

Answer 1

查看Apple的可访问性代码。

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

并像这样使用它：

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

Answer 2

您可以随时隐藏按钮

[button setHidden:YES];
