有人能帮忙吗?

    UISegmentedControl *unitsPicker                     = [[UISegmentedControl alloc] initWithItems:@[@"About", @"Terms", @"Privacy Policy"]];
    unitsPicker.frame                   = CGRectMake(0, CGRectGetMaxY(unitsLabel.frame) + kBottomPaddingConstant, CGRectGetWidth(_unitsContainer.frame), segmentHeightConstant);
    unitsPicker.autoresizingMask        = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
    unitsPicker.selectedSegmentIndex    = ![TemperatureUtility unitIsCelsius];
    [unitsPicker addTarget:self action:@selector(onUnitPickerChanged:) forControlEvents:UIControlEventValueChanged];
    unitsPicker.layer.cornerRadius   = 5.0f;
    unitsPicker.layer.borderColor    = [UIColorFromRGB(0xE9E9E9) CGColor];
    unitsPicker.layer.borderWidth    = 1.0f;
    unitsPicker.layer.masksToBounds  = YES;
    unitsPicker.clipsToBounds        = YES;
    [_unitsContainer addSubview:unitsPicker];
