1.在工程中添加
#import "AHReach.h"头文件
2.创建
AHReach *defAHReach reachForDefaultHost];
[defaultHostReach startUpdatingWithBlock:^(AHReach *reach) {
[self updateAvilabilityWithReach:reach];
}];
[self updateAvilabilityWithReach:defaultHostReach];
self.reaches = [NSArray arrayWithObjects:defaultHostReach, nil];
3.创建方法
- (void)updateAvilabilityWithReach:(AHReach *)reach{
if (![reach isReachable]) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"友情提示" message:@"没有网络" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
[alert show];
}
