如何在UIPickerView上获取文本？

Question

如果我使用带有自定义View的UIPickerView（3个组件）。如何从每个selectedRow获取UIPickerView上的每个文本？

感谢...

Answer 1

这取决于您决定如何将文本放入组件中。

例如，如果您使用myArray：

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    NSLog(@"%@",[myArray objectAtIndex:row]);
}

Answer 2

您可以使用选择器的委托方法

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component

{

    if(component==0)
    {
        int i=row;      //here i returns the row selected by you in picker component 0
    }
    else if(component==1)
    {
        int j=row;      //here j returns the row selected by you in picker component 1
    }
    else if(component==2)
    {
        int k=row;      //here k returns the row selected by you in picker component 2
    }

}
