下面是一个AFNetworking使用的小例子：
1.创建FKBooksController类 : UITableViewController
#import@interface FKBooksController : UITableViewController@property (nonatomic, strong) NSDictionary* selectedAuthor;@end
#import "FKBooksController.h"#import "FKAppDelegate.h"@interface FKBooksController (){ NSArray* books; FKAppDelegate* appDelegate;}@end@implementation FKBooksController- (void)viewDidLoad{ [super viewDidLoad]; appDelegate = [UIApplication sharedApplication].delegate; NSString* url = @"http://192.168.1.88:8888/AFNetworkingServer/books.json"; self.navigationItem.title = [NSString stringWithFormat:@"%@的图书" , [self.selectedAuthor objectForKey:@"name"]]; // 使用NSDictionary封装请求参数 NSDictionary *parameters = @{@"authorId": [self.selectedAuthor objectForKey:@"id"]}; // 使用AFHTTPRequestOperationManager发送GET请求 [appDelegate.manager POST:url parameters:parameters // 获取服务器响应成功时激发的代码块 success:^(AFHTTPRequestOperation *operation, id responseObject) { // 将服务器响应的JSON数据转换为Objective-C对象，赋值给books属性 books = responseObject; // 重新加载表格数据 [self.tableView reloadData]; } // 获取服务器响应失败时激发的代码块 failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"获取图书信息出现错误: %@", error); }];}- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return books.count;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ // 根据动态单元格原型的ID来获取可重用单元格 UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: @"bookCell" forIndexPath:indexPath]; // 获取当前行号在books中对应的数据 NSDictionary* book = [books objectAtIndex:indexPath.row]; // 获取单元格中3个控件，并为3个控件设置显示文本 UILabel* titleLable = (UILabel*)[cell viewWithTag:1]; titleLable.text = [book objectForKey:@"title"]; UILabel* authorLable = (UILabel*)[cell viewWithTag:2]; authorLable.text = [book objectForKey:@"author"]; UILabel* remarkLabel = (UILabel*)[cell viewWithTag:3]; remarkLabel.text = [book objectForKey:@"remark"]; return cell;}@end 2.创建FKAuthorsController类 : UITableViewController，导入FKBooksController和FKAppDelegate
#import "FKAuthorsController.h"#import "FKBooksController.h"#import "FKAppDelegate.h"@interface FKAuthorsController (){ NSArray* authors; FKAppDelegate* appDelegate;}@end@implementation FKAuthorsController- (void)viewDidLoad{ [super viewDidLoad]; appDelegate = [UIApplication sharedApplication].delegate; NSString* url = @"http://192.168.1.88:8888/AFNetworkingServer/authors.json"; // 使用AFHTTPRequestOperationManager发送GET请求 [appDelegate.manager GET:url parameters:nil // 获取服务器响应成功时激发的代码块 success:^(AFHTTPRequestOperation *operation, id responseObject) { // 将服务器响应的JSON数据转换为Objective-C对象，赋值给authors属性 authors = responseObject; // 重新加载表格数据 [self.tableView reloadData]; } // 获取服务器响应失败时激发的代码块 failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"获取作者信息出现错误: %@", error); }];}- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ UITableViewCell* cell = (UITableViewCell*)sender; // 获取激发跳转的单元格所在的NSIndexPath NSIndexPath* indexPath = [self.tableView indexPathForCell:cell]; // 获取即将跳转到的目标视图控制器 FKBooksController* booksController = (FKBooksController*) segue.destinationViewController; // 将用户选中的单元格的作者信息传给目标视图控制器 booksController.selectedAuthor = [authors objectAtIndex:indexPath.row];}// --------下面两个方法根据authors集合的元素来显示表格数据---------- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return authors.count;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: @"authorCell" forIndexPath:indexPath]; NSDictionary* dict = [authors objectAtIndex:indexPath.row]; cell.textLabel.text = [dict objectForKey:@"name"]; cell.detailTextLabel.text = [dict objectForKey:@"desc"]; return cell;}@end
