Swift显示图像UIImageview

让我们假装它叫做imageView.

以编程方式,您可以说：

imageView.image = UIImage(named: ("nameofasset"))

我实际上最终做的是创建一个静态函数,负责确定返回哪个图像：

class func GetImage(someValueWhichDrivesLogic: Int)->UIImage
{
    if (someValueWhichDrivesLogic == 1)
    { 
      assetName = "imageone" //note you don't add .png,you just give it the same name you have in your standard images folder in XCode6
    }
    else if (someValueWhichDrivesLogic == 2)
    {
      assetName = "imagetwo" //again,this is the actual name of my image
    }

    //Return an image constructed from what existed in my images folder based on logic above
    return UIImage(named: (assetName))

}

所以现在已经创建了上面的函数,你可以这样做：

imageView.image = GetImage(1) 
 imageView.image = GetImage(2)

这实际上会将图像动态分配给图像.你可以这样做,或者如果你真的做了一些简单的事情,就像点击按钮一样,你可以采取我上面指定的更简单的方法.

如果有任何问题,请告诉我！
