问题描述

我正在将此通知用于NSComboBox.唯一的问题是，当我在下拉列表中选择其他项目时，它始终会在组合框中显示以前选择的值.如何获得当前选择的值.我需要根据值使一些控件启用/禁用.

I am using this notification for NSComboBox. Only problem is when I select a different item in the dropdown it always show previously selected value in the combo box. How can I get the currently selected value. I need to make some controls enable/disable based on the value.

- (void)comboBoxSelectionDidChange:(NSNotification *)notification {
        NSComboBox *comboBox = (NSComboBox *)[notification object];

        NSLog(@"[comboBox stringValue] : %@", [salaryBy stringValue] );
}
