Ios UI分段控制错误分区

我正在用下面的代码自定义应用程序中的所有分段控件。最初，我将所选分段设置为索引2

在IOS 6中，一切都很完美。当我在IOS 5上测试应用程序时，我意识到分段控件的初始设置有一个bug。选定和未选定状态之间的分离图像设置不正确。因此，它看起来像这样

如果我通过点击segmentedcontrol来更改所选的段，则其行为正常。这非常奇怪。我应该做些什么来防止这种奇怪的行为

     UISegmentedControl *localSegmentedControl = [[UISegmentedControl alloc] init];

     if ([localSegmentedControl respondsToSelector:@selector(setBackgroundImage:forState:barMetrics:)]) {

    UIImage *segmentUnselectedSelectedDivider       = [UIImage imageNamed:@"segmentedControlSeperatorNS.png"];
    UIImage *segmentSelectedUnselectedDivider       = [UIImage imageNamed:@"segmentedControlSeperatorSN.png"];
    UIImage *segmentUnselectedUnselectedDivider     = [UIImage imageNamed:@"segmentedControlSeperatorNN.png"];

    UIImage *segmentUnselected = [[UIImage imageNamed:@"barButtonPlain.png"] stretchableImageWithLeftCapWidth:7 topCapHeight:0];
    UIImage *segmentSelected = [[UIImage imageNamed:@"doneButton.png"] stretchableImageWithLeftCapWidth:7 topCapHeight:0];


    [[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
                                               forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [[UISegmentedControl appearance] setBackgroundImage:segmentSelected
                                               forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];


    [[UISegmentedControl appearance] setDividerImage:segmentUnselectedUnselectedDivider
                                 forLeftSegmentState:UIControlStateNormal
                                   rightSegmentState:UIControlStateNormal
                                          barMetrics:UIBarMetricsDefault];

    [[UISegmentedControl appearance] setDividerImage:segmentSelectedUnselectedDivider
                                 forLeftSegmentState:UIControlStateSelected
                                   rightSegmentState:UIControlStateNormal
                                          barMetrics:UIBarMetricsDefault];

    [[UISegmentedControl appearance] setDividerImage:segmentUnselectedSelectedDivider
                                 forLeftSegmentState:UIControlStateNormal
                                   rightSegmentState:UIControlStateSelected
                                          barMetrics:UIBarMetricsDefault];


}

我认为这是一个已知的错误。 这里也是一样，有一个变通办法，可能对你有用

当我使用段控制时，我对同样的问题感到非常疲倦。我破解了那个密码

  UIImage *segmentSelected =
[[UIImage imageNamed:@"ikisiSecildiKirmizi.png"]
 resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 5, 15)];

                         forState:UIControlStateHighlighted];

在尝试了所有相关的方法后，在

我发现问题与分离线的宽度有关。中关于分段控制自定义的教程假设分离图像的宽度大于2px（在视网膜中）。

我把它们精确地做成了2倍宽，问题就解决了。

你的分段背景和分隔线的大小是多少？分段背景和分隔线的大小是相同的33x34，用于视网膜显示-我的答案有一个可行的解决办法。
