Question

如何用从UIPicker视图中选择的值填充UITextView ?用户从UIPickerView中选择一个类别值显示在UITextView中

Answer 1

需要实现UIPickerView的委托

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
 // Write your code here
 // yourTextField.text = [yourArray objectAtIndex:row];
}

Answer 2

请使用以下代码:

- (void)pickerView:(UIPickerView *)thepickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
switch (thepickerView.tag) {
    case PICKER_TYPE_A:{
        txtField.text = [arrayA objectAtIndex:row];
    }
        break;
    case PICKER_TYPE_B:{
        txtField.text = [arrayB objectAtIndex:row];
    }
        break;
    default:
        break;
}

}
