ios MKNetworkKit 的使用
常用框架比如：AFNetworking，ASIHttpRequest,SDWebImage,MKNetWorKit等。
iOS5已出来这么久了，而ASIHttpRequest的作者已经申明不更新了，在iOS5环境下，其实还是有些问题的。
现在MKNetWorkKi吸取了ASIHttpRequest与AFNetWorking的优点，并加入了自己特有的功能。
下载：
gitHub地址：https://github.com/MugunthKumar/MKNetworkKit.git
官方使用说明：http://blog.mugunthkumar.com/products/ios-framework-introducing-mknetworkkit/
github下载了该项目后，如果想运行其demo，一定要打开MKNetworkKit.xcworkspace该文件，若单独打开，则编译时会提示缺少libMKNetworkKit-iOS.a文件！！！
安装：
克隆下来之后把其中的 MKNetworkKit文件夹拖入项目，然后引入3个framework：
CFNetwork.Framework , SystemConfiguration.framework , Security.framework
注意：由于MKNetworkKit支持ARC，我们在项目中要开启ARC，不然会报错
开启ARC自动内存控制机制：(开启ARC之后项目中所有的dealloc 、release 、autorelease都得注释掉)
使用方法：
在需要使用的地方导入：#import"MKNetworkKit.h"
http方式：
GET请求：
[cpp] view plaincopy
-
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
-
MKNetworkOperation *op = [engine operationWithPath:@"/index" params:nil httpMethod:@"GET" ssl:NO];
-
[op addCompletionHandler:^(MKNetworkOperation *operation) {
-
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
-
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
-
NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
-
}];
-
[engine enqueueOperation:op];
POST请求：
[cpp] view plaincopy
-
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
