监听网络连接状态
使用AFNetWorking框架中的AFNetworkReachabilityManager实现。
使用下面的代码，可以监听设备的网络连接状态。
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager manager];
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
// do something
}];
[manager startMonitoring];
使用下面的代码，可以监听设备针对特定域名或者ip的连接状态。
//AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager managerForDomain:@"www.xxx.com"];
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager managerForAddress:@"xx.xx.xx.xx"];
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
// do something
}];
[manager startMonitoring];
判断蜂窝数据类型
CTTelephonyNetworkInfo *current = [[CTTelephonyNetworkInfo alloc] init];
NSString *tempst = current.currentRadioAccessTechnology;
CTCarrier *tempca = current.subscriberCellularProvider;
NSLog(@"\n%@\n%@", tempst, tempca);
//我的电信手机输出为：
CTRadioAccessTechnologyLTE
CTCarrier (0x170058300) {
Carrier name: [中国电信]
Mobile Country Code: [460]
Mobile Network Code:[11]
ISO Country Code:[cn]
Allows VOIP? [YES]
}
