iOS Question Verson Number,I need the version number so that I can set the correct speech rate:?

[John Woodsmall]

I need the version number so that I can set the correct speech rate:

#define SYSTEM_VERSION_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame) 02.#define SYSTEM_VERSION_GREATER_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending) 03.#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending) 04.#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending) 05.#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending) 06. 07. if (SYSTEM_VERSION_LESS_THAN(@"9.0")) 08. { 09. self.speechRate = 0.15; 10. } 11. 12. if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0")) 13. { 14. self.speechRate = 0.52; 15. } 16. 17. utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:self.speechLanguage]; 18. [utterance setRate:self.speechRate]; #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_LESS_THAN(@"9.0"))
{
self.speechRate = 0.15;
}

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0"))
{
self.speechRate = 0.52;
}

how do i do this is b4i?

you can use

App.OSVersion
