1.导入AFNetworking 3.0的框架
手动下载，并且拖动文件夹到工程
或者用pod工具
2.封装get方式、post方式请求数据
3.新建一个类CJNetworking
CJNetworking.h
#import
typedef enum{
StatusUnknown = -1, //未知网络
StatusNotReachable = 0, //没有网络
StatusReachableViaWWAN = 1, //手机自带网络2G,3G,4G
StatusReachableViaWiFi = 2 //wifi
}NetworkStatus;
typedef void( ^ CJResponseSuccess)(id response);
typedef void( ^ CJResponseFail)(NSError *error);
/**
* 方便管理请求任务。执行取消，暂停，继续等任务.
*/
typedef NSURLSessionTask CJURLSessionTask;
@interface CJNetworking : NSObject
/**
* 获取网络状态
*/
@property (nonatomic,assign)NetworkStatus networkStats;
/**
* 网络共享的单例对象
*/
+ (CJNetworking *)sharedCJNetworking;
/**
* 网络监测
*/
+ (void)startMonitoring;
/**
* get请求方法,block回调
*
* @param url 请求连接，根路径
* @param params 参数
* @param success 请求成功返回数据
* @param fail 请求失败
* @param showHUD 是否显示HUD
*/
+(CJURLSessionTask *)getWithUrl:(NSString *)url
params:(NSDictionary *)params
success:(CJResponseSuccess)success
fail:(CJResponseFail)fail
showHUD:(BOOL)showHUD;
/**
* post请求方法,block回调
*
* @param url 请求连接，根路径
* @param params 参数
* @param success 请求成功返回数据
* @param fail 请求失败
* @param showHUD 是否显示HUD
*/
+(CJURLSessionTask *)postWithUrl:(NSString *)url
params:(NSDictionary *)params
success:(CJResponseSuccess)success
fail:(CJResponseFail)fail
showHUD:(BOOL)showHUD;
@end
CJNetworking.m文件
pragma mark 类似懒加载
//单例
+(CJNetworking *)sharedCJNetworking{
static CJNetworking *handler = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
handler = [[CJNetworking alloc]init];
});
return handler;
}
+(NSMutableArray *)tasks{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
tasks = [[NSMutableArray alloc]init];
});
return tasks;
}
网络监控
+ (void)startMonitoring
{
// 1.获得网络监控的管理者
AFNetworkReachabilityManager *mgr = [AFNetworkReachabilityManager sharedManager];
// 2.设置网络状态改变后的处理
[mgr setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
// 当网络状态改变了, 就会调用这个block
switch (status)
{
case AFNetworkReachabilityStatusUnknown: // 未知网络
DLog(@"未知网络");
[CJNetworking sharedCJNetworking].networkStats=StatusUnknown;
break;
case AFNetworkReachabilityStatusNotReachable: // 没有网络(断网)
DLog(@"没有网络");
[CJNetworking sharedCJNetworking].networkStats=StatusNotReachable;
break;
case AFNetworkReachabilityStatusReachableViaWWAN: // 手机自带网络
DLog(@"手机自带网络");
[CJNetworking sharedCJNetworking].networkStats=StatusReachableViaWWAN;
break;
case AFNetworkReachabilityStatusReachableViaWiFi: // WIFI
[CJNetworking sharedCJNetworking].networkStats=StatusReachableViaWiFi;
DLog(@"WIFI--%d",[CJNetworking sharedCJNetworking].networkStats);
break;
}
}];
[mgr startMonitoring];
}
AFNetworking管理者
