推荐答案
而不是漫长和混乱的网址，你通常会看到，你可以创建更简单，更合乎逻辑的应用程序商店的链接。 iTunes在线商店有一个隐藏URL格式这更合乎逻辑。根据您链接到什么，你只需要在这些格式之一创建一个URL：
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:
- 歌手的名字或App Store，开发者的名字：http://itunes.com/Artist_Or_Developer_Name
- 专辑名称：
- 应用程序：
- 电影：
- 电视：
- 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
只是包含这个格式创建的电子邮件的正文中的URL。
Just include a url of this format in the body of the email you create.
（注意空格可能导致问题，但是我发现他们忽略完全为我工作 - 重定向到被称为Froot沟的应用程序。）
(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".)
（另请注意，如果这并不为你工作，iTunes的链接制造商是here)
(Also note that if this doesn't work for you, the iTunes link maker is here)
您code会是这样的（从矿中提取，匿名和未测试）
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
您可以在iPhone 3.0做的更好的东西，但我不能谈论这些呢。
You can do better things in iPhone 3.0, but I can't talk about those yet.
