如何在使用" fill"时删除标签栏项目之间的间距值"项目位置"选项?
我尝试过以下方法:
let tabBarController = window!.rootViewController as! UITabBarController
tabBarController.tabBar.itemSpacing = 0
let numberOfItems = CGFloat(tabBarController.tabBar.items!.count)
let tabBarItemSize = CGSize(width: tabBarController.tabBar.frame.width / numberOfItems, height: tabBarController.tabBar.frame.height)
tabBarController.tabBar.selectionIndicatorImage = UIImage.imageWithColor(color: UIColor.secondaryHighlight(), size: tabBarItemSize).resizableImage(withCapInsets: UIEdgeInsets.zero)
for item in tabBarController.tabBar.items! {
item.imageInsets = UIEdgeInsetsMake(0, 0, 0, 0)
}
extension UIImage {
class func imageWithColor(color: UIColor, size: CGSize) -> UIImage {
let rect: CGRect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
UIGraphicsBeginImageContextWithOptions(size, false, 0)
color.setFill()
UIRectFill(rect)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
return image
}
}
此结果始终如此(请注意第一个标签栏项左侧的绿线):

您也可以使用影响图像的标题偏移:
tabBar.items!.first?.titlePositionAdjustment = UIOffsetMake(30.0, 0.0);
tabBar.items!.last?.titlePositionAdjustment = UIOffsetMake(-30.0, 0.0);
在这种情况下,结果将是:
如何使用三个项目:

tabBarController?.tabBar.frame.origin.x = -2
tabBarController?.tabBar.frame.size.width += 2

对不起,迟到了。希望这有帮助!
tabBar.frame.size.width = self.view.frame.width + 4
tabBar.frame.origin.x = -2

能够控制所有标签栏项目的位置“不仅是第一个和最后一个”你可以像这样使用items数组索引:
tabBar.items?[1].titlePositionAdjustment = UIOffsetMake(-15.0 , 0.0)
tabBar.items?[2].titlePositionAdjustment = UIOffsetMake(15.0 , 0.0)
