UISegmentedControl错误的dividerImage

Question

我在我的应用程序中使用下面的code.Initially自定义所有分段的控件，我将选定的分段设置为索引2。

当我在IOS5上测试这个应用程序时，我意识到分段控制的初始设置在选中和未选中状态之间有一个bug.The分隔图像，而不是将right.Due设置为如下所示。

如果我通过点击segmentedcontrol行为来更改选定的段，normal.It非常weird.What等，我应该做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];


}

在尝试了所有相关方法后，在Customizing UISegmentedControl in iOS 5中进行了解释

我发现这个问题与分割line.The教程的宽度有关，在http://www.raywenderlich.com/4344/user-interface-customization-in-ios-5中，假设分割图像的宽度大于2px (在视网膜中)。我把它们做得恰好2px宽，问题就解决了。

我认为这是一个已知的bug。这是与这里相同的变通办法，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惫。我解决了那段代码

  UIImage *segmentSelected =
[[UIImage imageNamed:@"ikisiSecildiKirmizi.png"]
 resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 5, 15)];
UIImage *segmentUnselected =
[[UIImage imageNamed:@"ikisiSecilmediGri.png"]
 resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 5, 15)];
UIImage *segmentSelectedUnselected =
[[UIImage imageNamed:@"solSecili.png"]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 5, 15)];
UIImage *segUnselectedSelected =
[[UIImage imageNamed:@"sagSecili.png"]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 15, 5, 15)];

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

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

[fiyatSaat setDividerImage:segmentUnselectedUnselected
       forLeftSegmentState:UIControlStateNormal
         rightSegmentState:UIControlStateNormal
                barMetrics:UIBarMetricsDefault];

[fiyatSaat setDividerImage:segmentSelectedUnselected
       forLeftSegmentState:UIControlStateSelected
         rightSegmentState:UIControlStateNormal
                barMetrics:UIBarMetricsDefault];

[fiyatSaat setDividerImage:segUnselectedSelected
       forLeftSegmentState:UIControlStateNormal
         rightSegmentState:UIControlStateSelected
                barMetrics:UIBarMetricsDefault];

NSDictionary *attributes = [NSDictionary dictionaryWithObject:[UIColor blackColor]
                                                       forKey:UITextAttributeTextColor];
[fiyatSaat setTitleTextAttributes:attributes
                         forState:UIControlStateNormal];
NSDictionary *attributes2 = [NSDictionary dictionaryWithObject:[UIColor whiteColor]
                                                       forKey:UITextAttributeTextColor];
[fiyatSaat setTitleTextAttributes:attributes2
                         forState:UIControlStateHighlighted];
