编辑AppDelegate.m

#pragma mark - iVersion

#ifdef GITHUB
+ (void)initialize
 {
	//configure iVersion. These paths are optional - if you don't set
	//them, iVersion will just get the release notes from iTunes directly (if your app is on the store)

	[iVersion sharedInstance].remoteVersionsPlistURL = @"https://gpxj.github.io/versions.plist";
	[iVersion sharedInstance].localVersionsPlistPath = @"versions.plist";
	NSString *updateUrl = @"itms-services:///?action=download-manifest&url=https://gpxj.github.io/gpxj.plist";

	[iVersion sharedInstance].updateURL = [NSURL URLWithString:updateUrl];
}
#endif
