如何从JSONValue的NSDictionary中获取pickerView的值？

Question

在我的代码中，我使用JSONValue来获取NSDictionary。

字典看起来像这样：

{
   {ID = 0, NAME = "Patrick"},
   {ID = 1, NAME = "Ted"},
   {ID = 2, NAME = "John"},
   {ID = 3, NAME = "Allen"},
   {ID = 4, NAME = "David"}
}

我想在以下委托函数中返回相应ID的名称：

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

最有效的方法是什么？

Answer 1

例如：

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    // Assuming that you have just one component
    return [jsonDict[row] objectForKey: @(row) ];
}
