这是我的代码
var button = [UIButton?](count:3, repeatedValue: UIButton())
for i in 0...2{
button[i]!.tag = i
button[i]!.frame = CGRectMake(CGFloat(i) *(collectionViewLove?.frame.width)!/3,0,(collectionViewLove?.frame.width)!/3, 30)
button[i]!.setTitle(titleForButtonsOneSelected[i], forState: .Normal)
button[i]!.titleLabel?.adjustsFontSizeToFitWidth = true
button[i]!.layer.borderWidth = 1.0
button[i]!.layer.borderColor = UIColor.blueColor().CGColor
button[i]!.backgroundColor = UIColor.clearColor()
button[i]!.setTitleColor(UIColor.blackColor(), forState: .Normal)
view.addSubview(button[i]!)
}
问题是只显示添加到视图的最后一个按钮。如何在视图中显示所有按钮对象?
编辑: 我正在获取UIButton的帧值
(0.0,0.0,106.666666666667,30.0)
(106.666666666667,0.0,106.666666666667,30.0)
(213.333333333333,0.0,106.666666666667,30.0)
答案 0 :(得分:2)
let buttons = Array(0...2).map { number -> UIButton in
let button = UIButton(frame: CGRectMake(CGFloat(number) * collectionViewLove!.frame.width / 3, 0, collectionViewLove!.frame.width / 3, 30))
button.tag = number
button.setTitle(titleForButtonsOneSelected[number], forState: .Normal)
buttontitleLabel?.adjustsFontSizeToFitWidth = true
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.blueColor().CGColor
button.backgroundColor = UIColor.clearColor()
button.setTitleColor(UIColor.blackColor(), forState: .Normal)
view.addSubview(button)
return button
}
这样,buttons
中有3个不同的按钮。您也可以在那里自定义按钮。
编辑:
let buttons = Array(0...2).forEach {
let button = UIButton(frame: CGRectMake(CGFloat($0) * collectionViewLove!.frame.width / 3, 0, collectionViewLove!.frame.width / 3, 30))
button.tag = $0
button.setTitle(titleForButtonsOneSelected[$0], forState: .Normal)
buttontitleLabel?.adjustsFontSizeToFitWidth = true
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.blueColor().CGColor
button.backgroundColor = UIColor.clearColor()
button.setTitleColor(UIColor.blackColor(), forState: .Normal)
view.addSubview(button)
}

看起来button[i]!.frame = CGRectMake(CGFloat(i) *(collectionViewLove?.frame.width)!/3,0,(collectionViewLove?.frame.width)!/3, 30)
每次生成相同的帧,因此您的按钮将相互叠加。你需要在你的电话中有一些动态的东西让它们处于不同的位置并且可见。
