Question

帮助newby！我的应用程序有3个视图控制器。 VC＃3（*赞助商）将用户带到我的网站＆amp;所以我正在尝试为这个VC实现Reachability。我添加了系统配置框架＆amp;苹果可达性.H＆amp; .M文件到项目。已禁用ARC for Reachability .M文件＆amp; VC＃3 .M文件。项目B＆amp; R很好，但是当我断开网络连接时，我仍然没有得到弹出警报。我还将Reachability.h导入VC＃3。我错过了什么？请帮忙。

VC＃3（*赞助商）.M

     if (internetStats == NotReachable) {
         UIAlertView *alertOne = [[UIAlertView alloc] initWithTitle:@"Error"     
 message:@"Check Your Internet Connection" delegate:self cancelButtonTitle:@"Okay"   
 otherButtonTitles:nil];

Answer 1

对于有同样问题的人。我在.M文件中遗漏了这段代码。一旦我添加它，我的弹出警报就会很好。

`
 -(void)viewDidLoad {

     {

         [super viewDidLoad];
         [self hasInternet];

     }
