SBJson 框架使用2 SBJson解析数据 解析字典，数组
|
先导入SBJSON框架 导入sbjson 头文件 #import "SBJson.h" @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; dataArray = [[NSMutableArray alloc] init]; NSString* str = [NSString stringWithFormat:@"http://192.168.88.8/sns/my/user_list.php"]; NSURL* url = [NSURL URLWithString:str]; //下载 str = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; //解析 NSDictionary* dic = [str JSONValue]; //得到用户数组 NSArray* usersArray = [dic objectForKey:@"users"];
for (NSDictionary* userDic in usersArray) { //取得用户昵称 NSString* username = [userDic objectForKey:@"username"]; //取得用户头像url NSString* headimage = [NSString stringWithFormat:@"http://192.168.88.8/sns%@",[userDic objectForKey:@"headimage"]]; //把用户昵称和头像url保存到字典中 NSMutableDictionary* tmpDic = [NSMutableDictionary dictionaryWithCapacity:0]; [tmpDic setObject:username forKey:@"username"]; [tmpDic setObject:headimage forKey:@"headimage"]; //把字典存到表格数据源的数组中 [dataArray addObject:tmpDic]; } _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0,320,460) style:UITableViewStylePlain]; _tableView.dataSource = self; _tableView.delegate = self; [self.view addSubview:_tableView]; [_tableView release]; }
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return dataArray.count; } - (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"ID"]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"ID"] autorelease]; } //取出对应行的用户信息 NSDictionary* dic = [dataArray objectAtIndex:indexPath.row]; //用户昵称 cell.textLabel.text = [dic objectForKey:@"username"]; //用户头像url NSString* imageUrl = [dic objectForKey:@"headimage"]; //下载用户头像 NSData* data = [NSData dataWithContentsOfURL:[NSURL URLWithString:imageUrl]]; //显示用户头像 cell.imageView.image = [UIImage imageWithData:data]; return cell; } - (void)dealloc{ [dataArray release]; [super dealloc]; } @end
