是参考weather的，封装出一个单例，然后注册一个代理，当调用getdate的时 候，得到返回值result，然后在代理中调用返回方法。
*.h
#import "AFNetworking.h"
#import "EXConstants.h"
@protocol HttpClientDelegate;
@interface GamePlayerAPIClient : AFHTTPRequestOperationManager
+ (instancetype)sharedClient;
@property(weak) id<HttpClientDelegate> delegate;
-(void)getData:(NSString*)url withParameter:(NSDictionary*)parameters;
@end
@protocol HttpClientDelegate <NSObject>
-(void)GamePlayerAPIClient:(GamePlayerAPIClient *)client didUpdateWithData:(id)result;
-(void)GamePlayerAPIClient:(GamePlayerAPIClient *)client didFailWithError:(NSError *)error;
@end
*.m
#import "GamePlayerAPIClient.h"
@implementation GamePlayerAPIClient
+ (instancetype)sharedClient {
static GamePlayerAPIClient *_sharedClient = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_sharedClient = [[self alloc] initWithBaseURL:[NSURL URLWithString:SERVER]];
});
return _sharedClient;
}
/**
* 一个最基础的url
*/
- (id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
self.responseSerializer.acceptableContentTypes =[NSSet setWithObject:@"text/html"];
return self;
}
-(void)getData:(NSString*)url withParameter:(NSDictionary*)parameters{
NSLog(@"Url%@====",url);
[self POST:url parameters: parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"%@=====",responseObject);
id result=[self dealJsonDataWithUrlString:url withJson:responseObject];
if([self.delegate respondsToSelector:@selector(GamePlayerAPIClient:didUpdateWithData:)])
[self.delegate GamePlayerAPIClient:self didUpdateWithData:result];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%@===",error);
if ([self.delegate respondsToSelector:@selector(GamePlayerAPIClient:didFailWithError:)]) {
[self.delegate GamePlayerAPIClient:self didFailWithError:error];
}
}];
/**
* 返回当前的网络状态
*/
NSLog(@"net type=%d",[[self reachabilityManager] networkReachabilityStatus]);
}
/**
* 处理数据
*/
-(id)dealJsonDataWithUrlString:(NSString*) url withJson:(NSDictionary*)json
{
if ([json objectForKey:@"success"])
return [json objectForKey:@"result"];
else
return nil;
}
在掉用类中,继承HttpClientDelegate 接口然后实现getdate方法.
#pragma httpclient
/**getdate后的回掉方法.当请求错误时候,回调
*/
-(void)GamePlayerAPIClient:(GamePlayerAPIClient *)client didFailWithError:(NSError *)error
{
}
/**
* httpclientdelegate中的回调方法,当请求网络数据成功时回调该方法
*/
-(void)GamePlayerAPIClient:(GamePlayerAPIClient *)client didUpdateWithData:(id)result
{
NSLog(@"result:::::::::%@::::::::::::::",result);
NSArray *results=result;
NSLog(@"aa%@",[[results objectAtIndex:0] objectForKey:@"pageName"]);
}
/**
* 掉用httpclient的方法,然后将代理指向自己,到时候就回回调,该类中
* 的以上两种方法.
*/
-(void)getData
{
[GamePlayerAPIClient sharedClient].delegate=self;
[[GamePlayerAPIClient sharedClient] getData:@"/home" withParameter:nil];
}
当显示图片的时候:直接掉用
