如何在iOS7中更改UISegmentedControl边框的颜色？

Question

如何在不更改文本颜色的情况下更改iOS7中分段控制器的边框颜色？

如果我可以按原样保持线段之间的线（即与文本颜色相同），那将是理想的，但如果边框颜色更改意味着更改此线，那么也可以。

另请注意，文本（以及段之间的线条）具有设置的颜色
[segmCtrl setTintColor:choosenTintColor]

链接的答案确实回答了你的问题，但你必须在两行之间阅读。 以下是更改应用程序中所有分段控件样式的更清晰示例：

// Sets the tint color which typically sets the color of the segment images, text, dividers,
// borders, and selected segment. A translucent version of this color is also used to tint a
// segment when it is pressed and transitioning to being selected, as shown on the first
// segment below.
[[UISegmentedControl appearance] setTintColor:[UIColor blackColor]];

// The attributes dictionary can specify the font, text color, text shadow color, and text
// shadow offset for the title in the text attributes dictionary
[[UISegmentedControl appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor redColor]} forState:UIControlStateNormal];

对于app中的一个控件：

// Sets the tint color which typically sets the color of the segment images, text, dividers,
// borders, and selected segment. A translucent version of this color is also used to tint a
// segment when it is pressed and transitioning to being selected, as shown on the first
// segment below.
self.segControl.tintColor = [UIColor blackColor];

// The attributes dictionary can specify the font, text color, text shadow color, and text
// shadow offset for the title in the text attributes dictionary
[self.segControl setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor redColor]} forState:UIControlStateNormal];

所以我自己解决了这个问题。 我的解决方案为分段控件的边框提供了另一种颜色，没有别的。

为了只更改分段控件的边框颜色，我将另一个分段控件放在旧的控件之上。 我禁用了这个新用户的用户交互，我将所选段的图像设置为nil 。

UIView *header = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 40)];
// Header view for my main view

UISegmentedControl *subCat = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Segm 1", @"Segm 2", @"Segm 3", @"Segm 4", nil]]; 
// The UISegmentedController which I want to change color for

[subCat setFrame:CGRectMake(5, 5, [UIScreen mainScreen].bounds.size.width - 10, 30)];
[subCat setSelectedSegmentIndex:0];

UISegmentedControl *bcg = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@" ", @" ", @" ", @" ", nil]]; 
// The UISegmentedController I put on top of the other one

UIColor *subColor = [UIColor redColor];
[subCat setTintColor:subColor];
[bcg setFrame:CGRectMake(5, 5, [UIScreen mainScreen].bounds.size.width - 10, 30)];
[bcg setTintColor:[UIColor greenColor]];
[bcg setUserInteractionEnabled:NO];
[bcg setSelectedSegmentIndex:0];
[bcg setImage:nil forSegmentAtIndex:0]; // Removing highlight color


[header addSubview:subCat];
[header addSubview:bcg];

[[self view] addSubview:header];

我决定为所有项目放入viewWillAppear mySegmentControl.selectedIndex。 因此，所有段都会显示色调颜色。 当然，选择所有项目后，再次选择您的默认项目。
