UIPickerView选择项目的框架

Question

有没有办法获取当前所选UIPickerView项目的框架？

我尝试了以下内容（如下所示），但我总是得到一个零回复：

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


    UIView *selected = [pickerView viewForRow:row forComponent:component];
}

Answer 1

UIView *view=[picker viewForRow:[picker selectedRowInComponent:1] forComponent:1];


CGRect viewframe=[view frame];
