导入头文件
#import "Reachability.h"
创建三个按钮
// 按钮1
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setTitle:@"检测站点是否可连接" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(didClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
// 按钮2
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn1.frame = CGRectMake(100, 300, 300, 30);
[btn1 setTitle:@"检测234G是否可连接" forState:UIControlStateNormal];
[btn1 addTarget:self action:@selector(didClick234G) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn1];
// 按钮3
UIButton *btn3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn3.frame = CGRectMake(100, 400, 300, 30);
[btn3 setTitle:@"检测wifi是否可连接" forState:UIControlStateNormal];
[btn3 addTarget:self action:@selector(didClickwifi) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn3];
第一个按钮的点击事件 --- 检测站点是否可连接
// 检测站点是否可连接
-(void)didClick
{
// 检测站点，通过 Reachability 检测
Reachability *reach = [Reachability reachabilityWithHostName:@"https://www.taobao.com"];
// 开始检测
// 检测reach当前网络状态
switch ([reach currentReachabilityStatus]) {
case NotReachable:{ // 无网络状态
NSLog(@"该站点无法连接。");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"该站点无法连接" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];
[self presentViewController:alert animated:YES completion:^{
}];
}
break;
case ReachableViaWiFi:{
NSLog(@"通过wifi连接站点");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"通过wifi连接站点" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];

}];
[alert addAction:action];
[self presentViewController:alert animated:YES completion:^{
}];
}
break;
default:
break;
}
}
第二个按钮的点击事件 --- 检测234G是否可连接
// 检测234G是否可连接
-(void)didClick234G
{
Reachability *reach = [Reachability reachabilityForInternetConnection];
// 判断 234G 的状态
if ([reach currentReachabilityStatus] != NotReachable) {
NSLog(@"234G已连接");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"234G已连接" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];
[self presentViewController:alert animated:YES completion:^{
}];
}else{
NSLog(@"234G已断开");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"234G已断开" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];
[self presentViewController:alert animated:YES completion:^{
}];
}
}
第三个按钮的点击事件 -- 检测wifi是否可连接
// 检测wifi是否可连接
-(void)didClickwifi
{
Reachability *reach = [Reachability reachabilityForLocalWiFi];
// 判断
if ([reach currentReachabilityStatus] != NotReachable) {
NSLog(@"wifi已连接");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"wifi已连接" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];

}];
}else{
NSLog(@"wifi已断开");
// 提示框
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"wifi已断开" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];
[self presentViewController:alert animated:YES completion:^{
}];
}
}
wifi状态发生改变时弹出提示框
在 AppDelegate.h 中
// 定义成员变量
{
Reachability *_reach;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 注册通知，检测wifi状态的改变
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(TongZhi) name:kReachabilityChangedNotification object:nil];
// 初始化rearch
_reach = [Reachability reachabilityForLocalWiFi];
// 开始监听
[_reach startNotifier];
return YES;
}
点击事件
// 注册通知方法
-(void)TongZhi
{
if ([_reach currentReachabilityStatus] == NotReachable) {
NSLog(@"wifi已经断开");
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"已断开" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alert addAction:action];
[self.window.rootViewController presentViewController:alert animated:YES completion:^{
}];
}else{
NSLog(@"wifi已连接");
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"已连接" message:@"" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *action = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
