新建NetTool文件继承于NSObject在里面进行网络请求的封装
NetTool.h
-
定义两个枚举类型 然后重命名两个block
//get&post用枚举来展示数据类型 typedef NS_ENUM(NSUInteger, WSSResponseStyle) { WSSJSON, WSSDATA, WSSXML, }; //POST里body类型的枚举 typedef NS_ENUM(NSUInteger, WSSRequestStyle) { WSSBodyJSON, WSSBodyString, }; //重定义成功和失败的block typedef void(^blockofSuccess)(id result); typedef void(^blockofFailure)(NSError *error); @interface WSSNetTool : NSObject -
定义方法,分别是简单GET请求,简单POST请求,带加载小菊花的GET请求
//对AFN再进行GET封装,方便自己使用 + (void)GetNetByURL:(NSString *)urlString body:(id)body//GET的body体 headers:(NSDictionary *)headers//请求头 response:(WSSResponseStyle)response//枚举类型 success:(blockofSuccess)success//成功之后返回这个block failure:(blockofFailure)failure;//想要返回的数据类型(枚举类型的JSON/DATA/XML) //失败之后返回这个block,可以在里面打印error了解请求失败的原因 //对AFN再进行POST封装,方便自己使用 + (void)PostNetByURL:(NSString *)urlString body:(id)body//POST的body体 bodyStyle:(WSSRequestStyle)bodyStyle//body类型(枚举值) headers:(NSDictionary *)headers//请求头 response:(WSSResponseStyle)response success:(blockofSuccess)success failure:(blockofFailure)failure;//想要返回的数据类型(枚举类型的JSON/DATA/XML) //有小菊花的get封装 + (void)GetNet2ByURL:(NSString *)urlString body:(id)body//GET的body体 headers:(NSDictionary *)headers//请求头 response:(WSSResponseStyle)response success:(blockofSuccess)success failure:(blockofFailure)failure selfView:(UIView *)selfView;

- 带有加载小菊花的GET请求的实现
ps:这个方法的参数多了一个self.view是为了实现加载小菊花的添加以及加载结束小菊花的remove

//添加菊花
MBProgressHUD *mbView = [MBProgressHUD showHUDAddedTo:selfView animated:YES];
mbView.detailsLabelText = @"请耐心等待,网络加载中";
//6.发送请求

//取消菊花
