扩展介绍

目前内置的扩展实现有：
NJCSVCManager
NJCSViewAnimate
NJCSNotificationManager
NJCSUserDefaultManager
NJCSModelAdapter
其余的扩展都是接口层的实现，需要用户根据自己的情况具体实现,如：
NJCSHttp
NJCSAlert
NJCSLogComponent
等……

1:下面以NJCSHttp为例进行扩展接入介绍：
接口协议：

#import 
#import 

typedef void(^callbackBlock)(BOOL isSuccess, id resultData);

@protocol NJCSHttpInterfaceProtocol 
//
//  外部需要实现的http get请求
//
//  @param urlString   接口url 字符串
//  @param params      请求参数字典
//  @param resultBlock 请求结束后的block
//
- (void)Get:(NSString *)urlString params:(NSDictionary *)params resultBlock:(void(^)(BOOL isSuccess, id resultData))resultBlock;
//
//  外部需要实现的http post请求
//
//  @param urlString   接口url 字符串
//  @param params      请求参数字典
//  @param resultBlock 请求结束后的block
//
- (void)Post:(NSString *)urlString params:(NSDictionary *)params resultBlock:(void(^)(BOOL isSuccess, id resultData))resultBlock;

@end

@protocol NJCSHttpProtocol 

- (void)GetRequestWithURLString:(NSString *)urlString params:(NSDictionary *)params callbackConfig:(NSDictionary *)callbackConfig;
- (void)PostRequestWithURLString:(NSString *)urlString params:(NSDictionary *)params callbackConfig:(NSDictionary *)callbackConfig;

@end

说明：
协议NJCSHttpProtocol内部定义的方法是为了暴露给JS，NJCSHttp（接口层）必须实现该协议，而协议NJCSHttpInterfaceProtocol，是实现层必须要实现的（用户层），接口层源码如下：

#import "NJCSHttp.h"
#import "NJCSHttpInterfaceProtocol.h"
#import "NJCSBridge.h"

@interface NJCSHttp ()

@end

@implementation NJCSHttp

- (void)GetRequestWithURLString:(NSString *)urlString params:(NSDictionary *)params callbackConfig:(NSDictionary *)callbackConfig
{
    NSParameterAssert(urlString);
    NSParameterAssert(params);
    NSParameterAssert(callbackConfig);
    if ([_interface respondsToSelector:@selector(Get:params:resultBlock:)]) {
        NSMutableDictionary *tempParams = [params mutableCopy];
        if ([params objectForKey:@"runNative"]) {
            [tempParams removeObjectForKey:@"runNative"];
        }
        [_interface Get:urlString params:tempParams resultBlock:^(BOOL isSuccess, id resultData) {
            NSString *jsInstance = [callbackConfig objectForKey:@"instanceName"];
            NSString *methodName = [callbackConfig objectForKey:@"methodName"];
            NSParameterAssert(jsInstance);
            NSParameterAssert(methodName);
            NSMutableArray *params = [[NSMutableArray alloc] initWithCapacity:1];
            [params addObject:resultData];
            if (isSuccess) {
                [[NJCSBridge getInstance] runJSFunctionWithInstanceName:jsInstance methodName:methodName parameters:params];
            }else{
                //接口请求失败
            }
        }];
    }
}

- (void)PostRequestWithURLString:(NSString *)urlString params:(NSDictionary *)params callbackConfig:(NSDictionary *)callbackConfig
{
    NSParameterAssert(urlString);
    NSParameterAssert(params);
    NSParameterAssert(callbackConfig);
    if ([_interface respondsToSelector:@selector(Post:params:resultBlock:)]) {

        [_interface Post:urlString params:params resultBlock:^(BOOL isSuccess, id resultData) {
            NSString *jsInstance = [callbackConfig objectForKey:@"instanceName"];
            NSString *methodName = [callbackConfig objectForKey:@"methodName"];
            NSParameterAssert(jsInstance);
            NSParameterAssert(methodName);
            NSMutableArray *params = [[NSMutableArray alloc] initWithCapacity:1];
            [params addObject:resultData];
            if (isSuccess) {
                [[NJCSBridge getInstance] runJSFunctionWithInstanceName:jsInstance methodName:methodName parameters:params];
            }else{
                //接口请求失败
            }
        }];
    }
}

@end

在接口层的GetRequestWithURLString方法和PostRequestWithURLString方法中会各自调用实现层的Get和Post方法；
2：实现层代码如下：

#import "CommonHTTPTool.h"
#import "NJCSHttp.h"
#import "IMHTTPClient.h"

@implementation CommonHTTPTool

- (void)Get:(NSString *)urlString params:(NSDictionary *)params resultBlock:(void (^)(BOOL, id))resultBlock {

    IMHTTPClient *client = [[IMHTTPClient alloc] initWithURL:urlString parameters:params];

    [client imHTTPRequestOperationWithHTTPMethod:@"GET" success:^(IMHTTPRequestOperation *operation, id responseObject, id userInfo) {

        resultBlock(YES, responseObject);

    } failure:^(IMHTTPRequestOperation *operation, NSError *error, id userInfo) {

        resultBlock(NO, error);
    }];
}

- (void)Post:(NSString *)urlString params:(NSDictionary *)params resultBlock:(void (^)(BOOL, id))resultBlock {

    IMHTTPClient *client = [[IMHTTPClient alloc] initWithURL:urlString parameters:params];

    [client imHTTPRequestOperationWithHTTPMethod:@"POST" success:^(IMHTTPRequestOperation *operation, id responseObject, id userInfo) {

        resultBlock(YES, responseObject);

    } failure:^(IMHTTPRequestOperation *operation, NSError *error, id userInfo) {

        resultBlock(NO, error);
    }];
}

@end

说明：IMHTTPClient是实现层（用户层）自己封装的网络库。
