Swift – UIDevice orientations using iOS12
In iOS12 Apple introduced a new way to check if your device is in “flat” mode, or better is on your desk.
Let’s take a look at the reference:
iOS version?
Just a simple memo!
[[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch]
#define SYSTEM_VERSION_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame) #define SYSTEM_VERSION_GREATER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending) #define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending) #define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending) #define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)
if ( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0") )
{
// do something cool
}
Stupid trick, but useful!
