UISegmentedControl截断段标题 [英] UISegmentedControl truncates segment titles

问题描述

我的iPhone应用程序中有一个分段控件，在ios6上效果很好，但在ios7上，段切片被截断（文本有足够的空间，但无论如何都会截断它们）

I have a segmented control in my iPhone app that works great on ios6 but on ios7 the segment tiles are truncated (there is enough space for the text, but it truncates them anyway)

    self.segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
self.segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
NSDictionary *defaultTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:defaultFont,
                                       UITextAttributeFont,
                                       defaultFontColor,
                                       UITextAttributeTextColor,
                                       nil];
[self.segmentedControl setTitleTextAttributes:defaultTextAttributes forState:UIControlStateNormal];

NSDictionary *selectedTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:selectedFont,
                                        UITextAttributeFont,
                                        selectedFontColor,
                                        UITextAttributeTextColor,
                                        nil];
[self.segmentedControl setTitleTextAttributes:selectedTextAttributes forState:UIControlStateHighlighted];

有关如何解决这个问题的任何消息？为什么它会在ios6上正常工作但截断ios7上的标题......

Any sugestions on how to fix this? Why would it work right on ios6 but truncate the titles on ios7...

这是导致问题的代码......

This is the code that causes the problem...

      UIImage *unselectedBackgroundImage = [[UIImage imageNamed:@"product_details_segmentBckg"] resizableImageWithCapInsets:UIEdgeInsetsMake(1, 1, 1, 1)];
    /* Selected background */
    UIImage *selectedBackgroundImage = [[UIImage imageNamed:@"product_details_segmentBckg"] resizableImageWithCapInsets:UIEdgeInsetsMake(1, 1, 1, 1)];
    /* Image between two unselected segments */
    UIImage *bothUnselectedImage = [[UIImage imageNamed:@"product_details_segmentBckg"] resizableImageWithCapInsets:UIEdgeInsetsMake(1, 0, 1, 0)];
     /* Image between segment selected on the left and unselected on the right */
    UIImage *leftSelectedImage = [[UIImage imageNamed:@"product_details_segmentBckg"] resizableImageWithCapInsets:UIEdgeInsetsMake(1, 0, 1, 0)];
    /* Image between segment selected on the right and unselected on the right */
    UIImage *rightSelectedImage = [[UIImage imageNamed:@"product_details_segmentBckg"] resizableImageWithCapInsets:UIEdgeInsetsMake(1, 0, 1, 0)];

    if ([UIImage instancesRespondToSelector:@selector(imageWithRenderingMode:)]) {
#ifdef __IPHONE_7_0
        unselectedBackgroundImage = [unselectedBackgroundImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        selectedBackgroundImage = [selectedBackgroundImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        bothUnselectedImage = [bothUnselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        leftSelectedImage = [leftSelectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        rightSelectedImage = [rightSelectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
#endif
    }


    [[UISegmentedControl appearance] setBackgroundImage:unselectedBackgroundImage
                                               forState:UIControlStateNormal
                                             barMetrics:UIBarMetricsDefault];

    [[UISegmentedControl appearance] setBackgroundImage:selectedBackgroundImage
                                               forState:UIControlStateSelected
                                             barMetrics:UIBarMetricsDefault];

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

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

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

如果我发表评论，标签显示正常......但我需要背景图片.. ..
那么如何保持ios6的兼容性，同时在ios7上有自定义的分段控件

If I comment this out the labels show up alright ... but I need the background images .... So how do I keep ios6 compatibility while also having the customized segmented control on ios7

推荐答案

根据每个标题中的标题更改分段控件的宽度细分？
该问题的接受答案也是此问题的解决方案

Change width of a segmented control based on titles in each segment? The accepted answer to that question is also the solution to this problem
