我这里做判断网络使用的是一个第三方库：Reachability
大家可以直接在gitHup搜索下载；
下载之后添加到你所需要的工程中就可以了
下面上代码：
我的ViewController.h什么也没有声明
#import "ViewController.h"
#import "Reachability.h"
@interface ViewController ()
@property(nonatomic,strong)Reachability *reach;
@property(nonatomic,strong)UILabel *lable;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
_lable = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 300, 100)];
_lable.center = self.view.center;
_lable.font = [UIFont systemFontOfSize:50];
_lable.textColor = [UIColor blackColor];
[self.view addSubview:_lable];
_reach = [Reachability reachabilityForInternetConnection];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(netInter) name:kReachabilityChangedNotification object:nil];
[_reach startNotifier];
[self panduan];
}
-(void)panduan{
Reachability *reachable = [Reachability reachabilityForInternetConnection];
if ([reachable currentReachabilityStatus] == ReachableViaWiFi) {
NSLog(@"wifi - 已连接");
_lable.text = @"wifi - 已连接";
} else if ([reachable currentReachabilityStatus] == ReachableViaWWAN) {
NSLog(@"数据 - 已连接");
_lable.text = @"数据 - 已连接";
} else {
NSLog(@"无网络连接");
_lable.text = @"无网络连接";
}
}
-(void)netInter{
if (self.reach.currentReachabilityStatus == ReachableViaWiFi) {
_lable.text = @"123Wifi";
}else if (self.reach.currentReachabilityStatus == ReachableViaWWAN){
_lable.text = @"数据";
}else{
_lable.text = @"无网络";
}
}
-(void)dealloc{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
