我有一个UITabBarController,我使用此代码来设置选择指标图像:
let selectedBG = UIImage(named:"tabbarbgtest.png")?.resizableImageWithCapInsets(UIEdgeInsetsMake(0, 0, 0, 0))
UITabBar.appearance().selectionIndicatorImage = selectedBG

但是图像并没有填满整个空间 - 见下图:
图像只是一个红色正方形,在82x49px上有一个解决方案,但是如果图像更宽,它仍然无法填满整个空间.希望你们能帮忙 - 谢谢.
Microsoft 是否将客户端机密的到期日期更改为最长 2 年?不能再选择“从不”了吗?
如何将图像对齐到UIButton的右边缘,因此它将保留在所有设备的右边缘.下图显示了带有图像的UIButton(圆三角形).图像是来自iPhone 6的屏幕截图,它符合我的要求.但是对于iPhone 6+,图像向左移动一点点,对于iPhone 5,它向右移动,图像显示在外面.的UIButton.我知道这个的原因,这是因为我将UIEdgeInsets的左边设置为300,这非常适合iPhone 6.所以我的问题是如何才能为所有iPhone设置这种外观.谢谢.

self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 300, bottom: 0, right: 0)

self.tintColor = UIColor(CGColor: "#616366".CGColor)
