我试图在按钮上显示一些文本和图像。我正在从这里使用代码
let btnSort = UIButton.buttonWithType(UIButtonType.System) as! UIButton btnSort.frame = CGRectMake(2, 74, 140, 26) btnSort.tintColor = UIColor.whiteColor() btnSort.setImage(UIImage(named:"immgg"), forState: UIControlState.Normal) btnSort.imageEdgeInsets = UIEdgeInsets(top: 6,left: 100,bottom: 6,right: 14) btnSort.titleEdgeInsets = UIEdgeInsets(top: 0,left: -30,bottom: 0,right: 34) btnSort.setTitle("SORT", forState: UIControlState.Normal) btnSort.layer.borderWidth = 1.0 btnSort.layer.borderColor = UIColor.whiteColor().CGColor btnSort.addTarget(self, action: Selector("showSortTbl"), forControlEvents: UIControlEvents.TouchUpInside) self.view.addSubview(btnSort)
我可以在正确的位置看到图像,但是文本没有出现。我认为titleEdgeInsets没有用。
titleEdgeInsets
我尝试的代码获得了输出U所遇到的问题。
btnSort.backgroundColor = UIColor.redColor()->设置背景颜色并检查
btnSort.backgroundColor = UIColor.redColor()->
let btnSort = UIButton(type: UIButtonType.System) as UIButton! //this is Swift2.0 in this place use your code btnSort.frame = CGRectMake(2, 74, 140, 40) btnSort.tintColor = UIColor.whiteColor() btnSort.setImage(UIImage(named:"youtube16x16.png"), forState: UIControlState.Normal) btnSort.imageEdgeInsets = UIEdgeInsets(top: 6,left: 100,bottom: 6,right: 14) btnSort.titleEdgeInsets = UIEdgeInsets(top: 0,left: -30,bottom: 0,right: 34) btnSort.setTitle("SORT", forState: UIControlState.Normal) btnSort.layer.borderWidth = 1.0 btnSort.backgroundColor = UIColor.redColor() --> set the background color and check btnSort.layer.borderColor = UIColor.whiteColor().CGColor btnSort.addTarget(self, action: Selector("showSortTbl"), forControlEvents: UIControlEvents.TouchUpInside) self.view.addSubview(btnSort)
Swift3
let btnSort = UIButton(type: .system) btnSort.frame = CGRect(x: 2, y: 74, width: 140, height: 40) btnSort.tintColor = UIColor.white btnSort.setImage(UIImage(named:"youtube16x16.png"), for: .normal) btnSort.imageEdgeInsets = UIEdgeInsets(top: 6,left: 100,bottom: 6,right: 14) btnSort.titleEdgeInsets = UIEdgeInsets(top: 0,left: -30,bottom: 0,right: 34) btnSort.setTitle("SORT", for: .normal) btnSort.layer.borderWidth = 1.0 btnSort.backgroundColor = UIColor.red //--> set the background color and check btnSort.layer.borderColor = UIColor.white.cgColor btnSort.addTarget(self, action: #selector(ViewController.showSortTbl), for: UIControlEvents.touchUpInside) self.view.addSubview(btnSort)
and handle the action as
func showSortTbl() { // do your stuff here }
