Rather than the long and confusing urls that you usually see, you can create App Store links that are much simpler and more logical. The iTunes Store has a hidden URL format that’s much more logical. Depending on what you’re linking to, you just need to build a URL in one of these formats:
- Artist’s name or App Store developer’s name: http://itunes.com/Artist_Or_Developer_Name
- Album name: http://itunes.com/Artist_Name/Album_Name
- Apps: http://itunes.com/app/App_Name
- Movies: http://itunes.com/movie/Movie_Title
- TV: http://itunes.com/tv/Show_Title
Just include a url of this format in the body of the email you create.
(Note that spaces might cause problems, but I found that omitting them entirely worked for me – http://itunes.com/app/FrootGroove redirects to the app called “Froot Groove”.)
(Also note that if this doesn’t work for you, the iTunes link maker is here)
Your code will be something like this (extracted from mine, anonymised and not tested)
NSString* body = [NSString stringWithFormat:@"Get my app here - %@.\n",myUrl];
#if __IPHONE_OS_VERSION_MIN_REQUIRED <= __IPHONE_2_2
[NSThread sleepForTimeInterval:1.0];
NSString* crlfBody = [body stringByReplacingOccurrencesOfString:@"\n" withString:@"\r\n"];
NSString* escapedBody = [(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)crlfBody, NULL, CFSTR("?=&+"), kCFStringEncodingUTF8) autorelease];
NSString *mailtoPrefix = [@"mailto:[email protected]?subject=Get my app&body=" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// Finally, combine to create the fully escaped URL string
NSString *mailtoStr = [mailtoPrefix stringByAppendingString:escapedBody];
// And let the application open the merged URL
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailtoStr]];
#endif
You can do better things in iPhone 3.0, but I can’t talk about those yet.
