一个页面能定义多个UIPickerView吗

-(NSInteger)pickerView:(UIPickerView *)pickerView
numberOfRowsInComponent:(NSInteger)component
{
if(pickerView==agePicker)
{
return [agePickerData count];
}

else
{
return [monthPickerData count];
}
}

#pragma mark picker Delegate Methods
-(NSString *)pickerView:(UIPickerView *)pickerView
titleForRow:(NSInteger)row
forComponent:(NSInteger)component
{
if(pickerView==agePicker)
{
return [agePickerData objectAtIndex:row];
}
else
{
return [monthPickerData objectAtIndex:row];
}
}

这样就OK 了

我也不确定，还是看看专业人士怎么说。
