我希望我的应用程序可以有一个功能,让用户通过电子邮件向朋友发送我的应用程序的iTunes链接。如何实现?
谢谢。
谢谢。
请注意,如果此方法对您不起作用,则可以使用iTunes链接生成器此处。
您的代码将类似于以下内容(从我的代码中提取,已匿名化且未经测试)
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:xxx@wibble.com?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
iPhone 3.0 可以做更好的事情,但我现在还不能谈论那些。
在 OS 3.0 中,您可以使用 MessageUI 框架来实现此操作,而无需离开应用程序(对于早期版本的设备,使用 Jane 的代码作为后备):
- (void)sendEmail
{
NSString* body = [NSString stringWithFormat:@"Get my app here - %@.\n",myUrl];
#if __IPHONE_OS_VERSION_MIN_REQUIRED <= __IPHONE_2_2
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil && [mailClass canSendMail])
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
picker.subject = @"Get my app";
[picker setToRecipients:[NSArray arrayWithObject:@"xxx@wibble.com"];
[picker setMessageBody:body isHTML:NO];
[self presentModalViewController:picker animated:NO];
[picker release];
} else {
[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:xxx@wibble.com?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
}
#pragma mark -
#pragma mark Mail Composer Delegate
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
if (result == MFMailComposeResultFailed) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[error localizedDescription] message:[error localizedFailureReason] delegate:nil cancelButtonTitle:NSLocalizedString(@"OK", @"OK") otherButtonTitles:nil];
[alert show];
[alert release];
}
[self dismissModalViewControllerAnimated:YES];
}

协议。您还可以包含附件,在正文中使用HTML等。NSCharacterSet *trimSet = [[NSCharacterSet characterSetWithCharactersInString:@"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLKMNOPQRSTUVWXYZ0123456789"] invertedSet];
NSArray *trimmedAppname = [[NSString stringWithString:[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleName"]] componentsSeparatedByCharactersInSet:trimSet];
NSString *appStoreLink = @"http://itunes.com/app/";
for (NSString *part in trimmedAppname) appStoreLink = [NSString stringWithFormat:@"%@%@",appStoreLink,part];
NSLog(@"App store URL:%@",appStoreLink);
它会给你一个链接,像这样 http://itunes.com/app/angrybirds
顺便提一下,通过访问应用商店并点击“告诉朋友”按钮,您可以找到应用程序的ID链接,然后将电子邮件发送给自己。我发现这非常有用。
