Question

我有一个UIImageView的网格。 5S的布局看起来很好，但是6或6+的网格位于左上角。我决定尝试测试屏幕大小，这在this问题中解释（测试工作）;然后根据屏幕尺寸，按照this帖子中的建议，使用UIImageView重新定位CGRectMake。这是代码：

if UIDevice().userInterfaceIdiom == .Phone {
                switch UIScreen.mainScreen().nativeBounds.height {
                case 480:
                    println("iPhone Classic")
                case 960:
                    println("iPhone 4 or 4S")
                case 1136:
                    println("Default Setup")
                    println("iPhone 5 or 5S or 5C")
                case 1334:
                    dieImage0.frame = CGRectMake(42, 61, 152, 152)
                    dieImage1.frame = CGRectMake(247, 61, 152, 152)
                    dieImage2.frame = CGRectMake(42, 218, 152, 152)
                    dieImage3.frame = CGRectMake(247, 218, 152, 152)
                    dieImage4.frame = CGRectMake(42, 376, 152, 152)
                    dieImage5.frame = CGRectMake(247, 376, 152, 152)
                    dieImage6.frame = CGRectMake(42, 533, 152, 152)
                    dieImage7.frame = CGRectMake(247, 533, 152, 152)
                    println("iPhone 6")
                case 2208:
                    dieImage0.frame = CGRectMake(141, 201, 228, 228)
                    dieImage1.frame = CGRectMake(819, 201, 228, 228)
                    dieImage2.frame = CGRectMake(141, 723, 228, 228)
                    dieImage3.frame = CGRectMake(819, 723, 228, 228)
                    dieImage4.frame = CGRectMake(141, 1242, 228, 228)
                    dieImage5.frame = CGRectMake(819, 1242, 228, 228)
                    dieImage6.frame = CGRectMake(141, 1764, 228, 228)
                    dieImage7.frame = CGRectMake(819, 1764, 228, 228)
                    println("iPhone 6+")
                default:
                    println("unknown")
                }
            }

我知道测试有效，因为正确打印手机型号的信息，但图像的位置不会改变。然后当我触发segue转到第二个视图控制器

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "showMenu" {
            println("You pressed the menu button")
        }

错误＆＃34;致命错误：在展开可选值时意外发现nil＆＃34;被打印到控制台和案例中的第一行，以更改我正在测试的设备的图像位置抛出此错误：Thread 1: EXC_BAD_INSTRUCTION (code=EXC_1386_INVOP, subcode=0x0)。任何想法为什么会这样？

试试这个，

1）检查imageview的插座连接

2）在viewWillAppear下添加此func，如下所示

override func viewWillAppear(animated: Bool) {

...
...
let screenSize: CGRect = UIScreen.mainScreen().bounds
    screenSize.origin
    let screenWidth = screenSize.width;
    let screenHeight = screenSize.height;
  if(screenHeight == 667)
  { 
   //do Something
  }
  else if(screenHeight == 667)
  {
   //do Something
  }


}

根据设备的大小更改UIImageViews的位置
