iphone - UIPickerView 中的行分隔符

Question

如何在选取器 View 中隐藏分隔符。这是屏幕截图 .

这是我的自定义 UIPickerView 的代码。

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {

UILabel *label=[[UILabel alloc]init];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.textAlignment=NSTextAlignmentCenter;

switch (component) {
    case 0:
        label.text=[_hourArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:70];
        break;

    case 1:
        label.text=[_minutesArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:70];
        break;

    case 2:
        label.text=[_ampmArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:15];

        break;

    default:
        break;
}
return label;
}

-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 3;
}

请帮帮我。谢谢

隐藏 UIPickerView 的选择指示器:

_pickerView.showsSelectionIndicator = FALSE;

您可以使用代码(如上所述)或 Interface Builder 来实现:

根据Apple documentation :

On iOS 7 and later you cannot customzie the picker view’s selection indicator. The selection indicator is always shown, so setting this property to NO has no effect.
