Very nice! Thank you!
what's meaning of "GBDeviceInfo"
I get two errors during compile.
static let version = UIDevice.currentDevice().systemVersion.floatValue
error: "Value of type 'String' has no member 'floatValue'"
return GBDeviceInfo.deviceInfo().modelString
error: "Use of unresolved identifier 'GBDeviceInfo'"
@KimBin and @oddmagne:
replace
static let version = UIDevice.currentDevice().systemVersion.floatValue
with
static let version = (UIDevice.currentDevice().systemVersion as NSString).floatValue
Also add https://github.com/lmirosevic/GBDeviceInfo to your project.
@imkevinxu: very cool utility! Thanks a lot :)
Very handy. Love this. Thanks.
Works great, except from what I can see deviceHeight only works if the device is in portrait; otherwise in landscape, you'll get the height of the display (which is the width of the device).
static var TheCurrentDeviceHeight: CGFloat {
struct Singleton {
static let height = max(UIScreen.mainScreen().bounds.size.height, UIScreen.mainScreen().bounds.size.width)
}
return Singleton.height
}
... should do it
Very useful utility .. Thank you
Great. very useful...
i love it!
Ported it to Swift4: https://gist.github.com/RodrigoLGuimaraes/90086a28107809f58a0133e3e11419d3
