我努力让所有优惠券(UIImage)出现。例如,我有3张优惠券,当我运行我的代码时,它会一直显示第3张优惠券的图像。怎么没有显示前两个?提前谢谢。
override func viewDidLoad() {
var i: Int = 0
super.viewDidLoad()
self.view.backgroundColor = UIColor.white
CouponsViewController.PopulateDataCoupons()
i=0
repeat {
let imageName = MyCoupons.siteCoupons[i]//"Coupons1.jpg"
let image = UIImage(named: imageName!)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 50, y: 50, width: 350, height: 300)
view.addSubview(imageView)
i += 1 }
while (i < MyCoupons.count-1)
}
答案 0 :(得分:0)
您将每个UIImageView
对象放在同一位置。看看这一行:
imageView.frame = CGRect(x: 50, y: 50, width: 350, height: 300)
尝试更改每次迭代的x
或y
坐标以查看每个图片,如下所示:
let height = 350
i = 0
repeat {
let imageName = MyCoupons.siteCoupons[i]//"Coupons1.jpg"
let image = UIImage(named: imageName!)
let imageView = UIImageView(image: image!)
imageView.frame = CGRect(x: 50, y: i * height, width: 350, height: height)
view.addSubview(imageView)
i += 1
}
while (i < MyCoupons.count - 1)

正如@Mick MacCallum指出的那样。您应该考虑UIImageView的高度。请参阅上面的更改。
