我在iOS7中改变分段控件的边框颜色时遇到了问题。我在stackoverflow上找到了以下建议:
[[UISegmentedControl appearance] setTitleTextAttributes:@{
UITextAttributeTextColor: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
UITextAttributeTextShadowColor: [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0],
UITextAttributeFont: [UIFont fontWithName:@"Arial-Bold" size:0.0],
NSForegroundColorAttributeName : [UIColor redColor],
} forState:UIControlStateSelected];
[self.segmentedControl setTitleTextAttributes:@{
UITextAttributeTextColor: [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
UITextAttributeTextShadowColor: [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0],
UITextAttributeFont: [UIFont fontWithName:@"Arial-Bold" size:0.0],
NSForegroundColorAttributeName : [UIColor redColor],
} forState:UIControlStateNormal];
但无论哪种情况,我的边框仍然是蓝色的。我似乎无法通过settitleTextAttributes更改字体阴影、边框颜色或其他任何内容。
我该如何调整边框颜色?
