如何從JSONValue的NSDictionary中獲取pickerView的值？

Question

在我的代碼中，我使用JSONValue來獲取NSDictionary。

詞典是這樣的：

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

我想在下面的委託函數返回相應的ID名稱：

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

什麼是最有效的方式來做到這一點？

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) ]; 
}
