使用方法：
先导入头文件 #import "ZJLAFRequest.h"
以post请求为例子：NSString *hostString = @"xxxxx"; NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"22",@"userid",nil]; ZJLAFRequest *httpReauest = [ZJLAFRequest sharedInstance]; [httpReauest POST:hostString dict:dic progressFloat:^(float progressFloat){ }succeed:^(id responseObject) { //请求成功以后 } failure:^(NSError *error) { //请求失败 NSLog(@"%@", error); }];
