iPhone：如何在 UIPickerView 中隐藏滚动指示器
我在 UIPickerView 中使用 UITextField 来显示图片和文本。在选择器中滚动时，会显示垂直滚动指示器。我怎样才能让它消失？
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view{
UITextField *field = (UITextField*) view;
if (view == nil) {
field = [[[UITextField alloc] initWithFrame:CGRectMake(0, 0, 280, 44)]autorelease];
field.backgroundColor = [UIColor clearColor]; // overriding highlighted selection
field.delegate = self;
}

field.delegate = self;
