我有三个不同的按钮。 当我单击这些按钮时, 它会显示一个拾取器视图。 我每次使用相同的拾取器视图, 但拾取器视图中的行应该不同, 取决于按下哪个按钮 。
我如何使拾取器视图显示我想要的行, 取决于按下哪个按钮?
I assume you use the UIPickerView and the delegate for that pickerView is the same viewController as where you buttons are.
I would create 4 arrays, 3 for each button with the values to show in the picker and 1 array that is used by – pickerView:titleForRow:forComponent:
NSArray *pickerData;
NSArray *button1Data;
NSArray *button2Data;
NSArray *button3Data;
然后在按钮的 IB 动作中( 或者您在代码中设置目标与选择器)
- (IBAction)button1Action:(id)sender {
[pickerData release];
pickerData = [button1Data retain];
}
- (IBAction)button2Action:(id)sender {
[pickerData release];
pickerData = [button2Data retain];
}
etc...
