Question

我使用以下代码将JSON数据（从SOAP服务）转换为NSDictionary。

-(void)retriveFromSYSoapTool:(NSMutableArray *)_data{
    NSLog(@"data: %@",_data);
    NSArray *value = [_data valueForKey:@"GetDemoDataResult"];
    NSError *error;
    NSData *objData = [value[0] dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objData options:NSJSONReadingMutableContainers error:&error];
    NSLog(@"%@",json);
}

输出

2017-04-04 13:03:51.085 SoapService[18444:588594] (
        {
        firstName = "1 Jhon";
        lastName = Macay;
    },
        {
        firstName = "2 William";
        lastName = Proter;
    },
        {
        firstName = "3 Joe";
        lastName = Root;
    },
        {
        firstName = "4 Brendon";
        lastName = Haejoy;
    },
        {
        firstName = "5 Jhon";
        lastName = Snow;
    },
        {
        firstName = "6 Theon";
        lastName = Greyjoy;
    }
)

我是否需要将此转换为其他？或者如何在UITable View中绑定上述输出？

Answer 1

要使用表格视图，您需要数组

Checkout this简单表格视图教程

Answer 2

选择一个NSMutuableArray并将dictionary添加到此array

NSMutableArray *array = [[NSMutableArray alloc] init];

[array addObject: json];

//Than Reload Tableview

Note: Declare array Globally to access in your class

tableview显示

等数据

cell.label.text = [[array objectAtIndex:indexPath.row]valueForKey:@"firstName"];

Answer 3

将 json 数据存储到全球声明NSArray 。

-(void)retriveFromSYSoapTool:(NSMutableArray *)_data{
    NSLog(@"data: %@",_data);
    NSArray *value = [_data valueForKey:@"GetDemoDataResult"];
    NSError *error;
    NSData *objData = [value[0] dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objData options:NSJSONReadingMutableContainers error:&error];
    NSLog(@"%@",json);
    DataArray = [NSArray arrayWithObjects:json, nil];
    [tableView reloadData];
}

此处 DataArray 是全局声明的NSArray对象;

现在编写UITableView数据源方法。

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return DataArray.count;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"jsoncell" forIndexPath:indexPath];
    NSDictionary *dict = DataArray[indexPath.row];
    NSString *output = [NSString stringWithFormat:@"%@ %@",dict[@"firstName"],dict[@"lastName"]];
    cell.textLabel.text = output;
    return cell;

}

Answer 4

应该是这样的

在.h文件中声明jsonArray

@property (strong, nonatomic)  NSMutableArray *jsonArray;

添加以下行viewDidLoad

self.jsonArray = [[NSMutableArray alloc]init];


 -(void)retriveFromSYSoapTool:(NSMutableArray *)_data{

    NSLog(@"data: %@",_data);

    NSArray *value = [_data valueForKey:@"GetDemoDataResult"];

    NSError *error;

    NSData *objData = [value[0] dataUsingEncoding:NSUTF8StringEncoding];

    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objData options:NSJSONReadingMutableContainers error:&error];

    NSLog(@"%@",son);

   [self.jsonArray addObject:[[json objectForKey:@"firstname"]stringByAppendingString:[json objectForKey:@"lastname"]];

   [tableViewName reloadData];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return self.jsonArray.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:  (NSIndexPath *)indexPath{

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];

if (cell == nil) {

    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault   reuseIdentifier:@"cell"];

}

cell.textLabel.text = [self.jsonArray objectAtIndex:indexPath.row];

    return cell;
}

如何将NSDictionary数据绑定到目标c中的表视图？
