某些屏幕尺寸的Swift ios隐藏按钮

Question

I wonder how I can hide a button on certain screen sizes. What I am trying to do is to show a button when the app is running on a iphone

Right now I have setup size classes, setting a width/height to 0 on a certain size class (ipads). This works, but is there any other way to do it?

Thanks

Answer 1

The best way is actually to use size classes, as it is only dependant on the actual screen size. It would be bad if the size of the app is like an iPhone, but runs on an iPad in split view mode

Answer 2

You can use UIDevice.currentDevice().model , which is equal to "iPhone" if the app is running on an iPhone or "iPad" if the app is running on an iPad.

Code snippet:

var model = UIDevice.currentDevice().model
if model == "iPhone" {
thatbutton.hidden = false
} else {
thatbutton.hidden = true
}
