iOS AFNetworking

1. 先用Pods 把第三方原件 加入進來

platform :ios, '5.0'
pod 'AFNetworking', '~> 1.2'

2.

將AFNetworking 加入參考

#import <AFNetworking.h>

可以到Xcode資料夾底下 Supporting Files
的 .pch 檔案的裡面

#import <Availability.h>

#ifndef __IPHONE_5_0

#warning "This project uses features only available in iOS SDK 5.0 and later."

#endif

#ifdef __OBJC__

    #import <UIKit/UIKit.h>

    #import <Foundation/Foundation.h>

    #import <AFNetworking.h>

#endif

3.
簡單範例

    static NSString *const BaseURLString = @"http://140.131.95.60/TESTAPI/";

    

    NSString *weatherUrl = [NSString stringWithFormat:@"%@api/product", BaseURLString];

    

    NSURL *url = [NSURL URLWithString:weatherUrl];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    AFJSONRequestOperation *operation =

    [AFJSONRequestOperation JSONRequestOperationWithRequest:request

    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {

//                                                        self.weather  = (NSDictionary *)JSON;

//                                                        self.title = @"JSON Retrieved";

//                                                        [self.tableView reloadData];

        NSLog(@"%@",response);

        NSLog(@"%@",JSON);

                                                    }

failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather"

        message:[NSString stringWithFormat:@"%@",error]delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

            [av show];

    }];

    

    [operation start];

4.接下來要解出json的封包

        NSDictionary *JSONdata = (NSDictionary *)JSON;

        

        for (NSDictionary *carDict in JSONdata) {

            

            NSString * email = [carDict valueForKey:@"email"];

                    NSLog(@"%@",email);

             }
