UISegment控件外观导致问题 [英] UISegmentcontrol appearances causing issues

问题描述

我需要帮助我的UISegment外观，我在我的应用程序委托中设置一切正常。

i need help on my UISegment appearances, i set this in my app delegate everything works fine.

直到我添加此代码来更改我选择的分段颜色，它导致了一个问题。

till i add in this code to change my selected segment color, it caused an issues.

我在viewDidLoad时调用了IBAction。

i called the IBAction when viewDidLoad.

它应该显示这个

但相反它显示了这个，我知道是外观问题，但现在不确定修复它...当我评论外观代码时它将是第一张图片。

but instead it show this, i know is the appearance issues but not sure now to fix it...when i commented the appearances codes it will the first picture.

appdelegate

appdelegate

   //normal segment
    [[UISegmentedControl appearance] setTitleTextAttributes:
     [NSDictionary dictionaryWithObjectsAndKeys:
      [UIFont fontWithName:@"Rokkitt" size:20.0],UITextAttributeFont,
      [UIColor colorWithRed:75.0/255.0 green:75.0/255.0 blue:75.0/255.0 alpha:1.0], UITextAttributeTextColor, 
      [UIColor clearColor], UITextAttributeTextShadowColor,
      [NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
      nil] forState:UIControlStateNormal];


    //selected segment
    [[UISegmentedControl appearance] setTitleTextAttributes:
     [NSDictionary dictionaryWithObjectsAndKeys:
      [UIFont fontWithName:@"Rokkitt" size:20.0],UITextAttributeFont,
      [UIColor whiteColor], UITextAttributeTextColor, 
      [UIColor clearColor], UITextAttributeTextShadowColor,
      [NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
      nil] forState:UIControlStateHighlighted];

IBAction电话

IBAction call

// Get number of segments
    int numSegments = [infoSegment.subviews count];

    // Reset segment's color (non selected color)
    for( int i = 0; i < numSegments; i++ ) {
        // reset color
        [[infoSegment.subviews objectAtIndex:i] setTintColor:[UIColor colorWithRed:196.0/255.0 green:223.0/255.0 blue:155.0/255.0 alpha:1]];
    }

    // Sort segments from left to right
    NSArray *sortedViews = [infoSegment.subviews sortedArrayUsingFunction:compareViewsByOrigin context:NULL];

    // Change color of selected segment
    [[sortedViews objectAtIndex:infoSegment.selectedSegmentIndex] setTintColor:[UIColor colorWithRed:51.0/255.0 green:166.0/255.0 blue:85.0/255.0 alpha:1]];
        // Remove all original segments from the control
    for (id view in infoSegment.subviews) {
        [view removeFromSuperview];
    }

    // Append sorted and colored segments to the control
    for (id view in sortedViews) {
        [infoSegment addSubview:view];
    }

推荐答案

看起来像上面的代码只设置 UIControlStateNormal 的外观，还需要设置 UIControlStateSelected 的外观。

It looks like the code above is only setting appearance for UIControlStateNormal, you also need to set the appearance for UIControlStateSelected.
