How can I check the software version of our application programmatically?

Question

I made an application and I installed it on my iphone, but I want to check the version of the application. How can I do that?

Answer 1

NSString *versionString = [[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*)kCFBundleVersionKey]; 

Answer 2

Here are some macros:

 #define BUNDLE_VERSION_EQUAL_TO(v) ([[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey] compare:v options:NSNumericSearch] == NSOrderedSame) #define BUNDLE_VERSION_GREATER_THAN(v) ([[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey] compare:v options:NSNumericSearch] == NSOrderedDescending) #define BUNDLE_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey] compare:v options:NSNumericSearch] != NSOrderedAscending) #define BUNDLE_VERSION_LESS_THAN(v) ([[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey] compare:v options:NSNumericSearch] == NSOrderedAscending) #define BUNDLE_VERSION_LESS_THAN_OR_EQUAL_TO(v) ([[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey] compare:v options:NSNumericSearch] != NSOrderedDescending)
