用对block对AFNetWorking 进行简单的封装

新建类HttpTool继承NSObject
@interface BAHttpTool : NSObject

一、封装用AFN发送GET请求

 /**


发送一个GET请求 用AFN
 
@param url 请求路径
@param params 请求参数
@param success 请求成功后的回调（请将请求成功后想做的事情写到这个block中）
@param failure 请求失败后的回调（请将请求失败后想做的事情写到这个block中）
 */


 
(void)Get:(NSString *)url params:(id)params success:(void (^)(id responseObj))success failure:(void (^)(NSError *error))failure;
 
 

实现代码

 
(void)Get:(NSString *)url params:(id)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
 {
 
// 1.获得请求管理者
 
AFHTTPRequestOperationManager *mar = [AFHTTPRequestOperationManager manager];
 // 设置请求格式
 [mar GET:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
 if (success) {
 success(responseObject);
 }
 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
 if (failure) {
 failure(error);
 }
 }];
 

}
 

使用方法

 [BAHttpTool Get:@"http:xxx.xx.xx" params:nil success:^(id responseObj) {

} failure:^(NSError *error) {
    
}]

二、封装用AFN发送POST请求

(void)Post:(NSString *)url params:(id)params success:(void (^)(id responseObj))success failure:(void (^)(NSError *error))failure;
 

实现代码

(void)Post:(NSString *)url params:(id)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
 {
 // 1.获得请求管理者
 // AFHTTPRequestOperationManager
 AFHTTPRequestOperationManager *mar = [AFHTTPRequestOperationManager manager];
 [mar POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
 if (success) {
 success(responseObject);
 }
 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
 if (failure) {
 failure(error);
 }
 }];

}

使用方法

 [BAHttpTool Post:@"http:xxx.xx.xx" params:nil success:^(id responseObj) {

} failure:^(NSError *error) {
    
}]

封装AFN网络加载指示器

 typedef NS_ENUM(NSInteger, NetworkReachabilityStatus) {
 NetworkReachabilityStatusUnknown = -1,
 NetworkReachabilityStatusNotReachable = 0,
 NetworkReachabilityStatusReachableViaWWAN = 1,
 NetworkReachabilityStatusReachableViaWiFi = 2,
 };
 +(void)setReachabilityStatusChangeBlock:(void(^)(NetworkReachabilityStatus status))block;
 +(void)stopMonitoring；
 

实现代码

+(void)setReachabilityStatusChangeBlock:(void(^)(NetworkReachabilityStatus status))block{
//监测网络状态
AFNetworkReachabilityManager *netMan = [AFNetworkReachabilityManager sharedManager];
[netMan setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    switch (status) {
            
        case AFNetworkReachabilityStatusUnknown: // 未知网络
            if (block) {
                block(NetworkReachabilityStatusUnknown);
            }
            
            break;
        case AFNetworkReachabilityStatusNotReachable: // 没有网络
            if (block) {
                block(NetworkReachabilityStatusNotReachable);
            }
            break;
            
        case AFNetworkReachabilityStatusReachableViaWWAN: // 手机自带网络
            if (block) {
                block(NetworkReachabilityStatusReachableViaWWAN);
            }
            break;
            
        case AFNetworkReachabilityStatusReachableViaWiFi: // WIFI
            if (block) {
                block(NetworkReachabilityStatusReachableViaWiFi);
            }
            
            break;
    }
}];

[netMan startMonitoring];

}
 

 +(void)stopMonitoring
 {

AFNetworkReachabilityManager *netMan = [AFNetworkReachabilityManager sharedManager];
[netMan stopMonitoring];

}
