尽我所能,我无法解决iOS7 iPhone应用程序的UISegmentedControl错误.

当我创建分段控件时,我使用此代码:

NSArray *segmentedControlItemArray = [NSArray arrayWithObjects: @"Nominal:\n27 inch", @"Actual:\n700c x 23mm", @"Actual:\n700c x 20mm", nil];
_wheelDiameterSegmentedControl = [[UISegmentedControl alloc] initWithItems:segmentedControlItemArray];
_wheelDiameterSegmentedControl.frame = CGRectMake(0, 102, 290, 50);
_wheelDiameterSegmentedControl.selectedSegmentIndex = 0;
_wheelDiameterSegmentedControl.tintColor = [UIColor colorWithRed:0.35 green:0.4 blue:0.9 alpha:1.0];

for (id segment in [_wheelDiameterSegmentedControl subviews]) {
    for (id label in [segment subviews]) {
        if ([label isKindOfClass:[UILabel class]]) {
            UILabel *titleLabel = (UILabel *) label;
            titleLabel.numberOfLines = 0;   
        }   
    }  
}

[_wheelDiameterSegmentedControl addTarget:self
                     action:@selector(pickOne:)
           forControlEvents:UIControlEventValueChanged];

[_wheelDiameterMenuContainer addSubview:_wheelDiameterSegmentedControl];

可悲的是,我无法发布图像,或者我会向您展示我想要的控件:UISegmented Control中的每个段都有两行文本,换行符正是我要求它的位置.

但是,在旋转时,我想保持分段控件的全宽度,并且换行在宽段中看起来很傻.因此,在willAnimateRotationToInterfaceOrientation中,我包含了以下代码,字符串中没有换行符:

    [_wheelDiameterSegmentedControl setFrame:CGRectMake(0, …
