我想从数组中的 payment_modes 获取所有图标网址。就像这样

216.70.96.219 \ / _媒体\ /图像\ / ICO \ /ico_pm_cod.gif

Answer 1

你想要使用NSJSONSerialization类。您的代码将如下所示：

    NSDictionary* json = [NSJSONSerialization
                          JSONObjectWithData:responseData
                          options:kNilOptions
                          error:&error];

    NSArray* commands = [json objectForKey:@"foo"];

请注意，我的JSON中有一个数组，但它可能很容易成为字典。

Answer 2

将json字符串转换为Foundation对象

NSString *jsonString = ...;
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:jsonString options:0 error:nil];
NSArray *payment_modes = [dict objectForKey:@"payment_modes"];

如何在iOS中获取json数据？
