AFNetworking 是 iOS 一個使用很方便的網路開發框架。今天我們就簡單介紹如何在我們的專案中使用它。

1、從官網下載最新的AFNetworking程式碼。

2、將AFNetWorking和UIKit+AFNetworking資料夾匯入專案
3、新增類庫 Security.framework、MobileCoreServices.framework、SystemConfiguration.framework
4、在使用的地方匯入

#import "AFNetworking.h"

#import"UIKit+AFNetworking.h"

5、網路url訪問測試。

    NSString

NSString *URLTmp1 = [URLTmpstringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

//轉碼成UTF-8 否則可能會出現錯誤

URLTmp = URLTmp1;

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: URLTmp]];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

        NSLog(@"Success: %@", operation.responseString);

        NSString *requestTmp = [NSString stringWithString:operation.responseString];

        NSData *resData = [[NSData alloc] initWithData:[requestTmp dataUsingEncoding:NSUTF8StringEncoding]];

        //系統自帶JSON解析

        NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:resData options:NSJSONReadingMutableLeaves error:nil];

        NSLog(@"success:%@",resultDic);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        NSLog(@"Failure: %@", error);

        //[SVProgressHUD dismissWithError:@"提交失敗，請重試"];

    }];

    [operation start];

6、如何獲取一張網路圖片

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10.0f, 150.0f, 200.0f, 200.0f)];

    [imageView setImageWithURL:[NSURL URLWithString:url]];

    [self.view addSubview:imageView];
