Upgrading a Target from iPhone to iPad

14 abril 2010 • By

If you have an existing iPhone application that you want to upgrade to run on iPad devices you need to upgrade the target that builds your iPhone application into a target that can build both an iPhone and an iPad application, or add a target to your project for building the iPad application.

To upgrade an iPhone target for iPad development, select the target in the Groups & Files list and choose Project > Upgrade Current Target for iPad.

For details about iPad-application development, see iPad Programming Guide.

Little and fast-to-understand test for to know the language of iPhone device:

NSString* language    = [[NSLocale preferredLanguages] objectAtIndex:0];                // en  
NSString* countryCode = [[NSLocale currentLocale] objectForKey: NSLocaleCountryCode];   // US
// Console Log, only for debug...
BOOL result;
if ([countryCode isEqualToString:@"GB"] || [countryCode isEqualToString:@"US"] || [countryCode isEqualToString:@"CA"])
	result = YES;
	result = NO;
