Launch Apple Mail App from within my own App?
提问by cschuff
What I already found is
我已经发现的是
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto:"]];
But I just want to open the Mail app not only a composer view. Just the mail app in its normal or last state.
但我只想打开邮件应用程序，而不仅仅是一个作曲家视图。只是处于正常或最后状态的邮件应用程序。
Any ideas?
有任何想法吗？

Apparently Mail application supports 2nd url scheme - message://which ( I suppose) allows to open specific message if it was fetched by the application. If you do not provide message url it will just open mail application:
显然邮件应用程序支持第二个 url 方案 -message://如果它被应用程序获取，它（我想）允许打开特定的消息。如果您不提供消息 url，它将只打开邮件应用程序：
NSURL* mailURL = [NSURL URLWithString:@"message://"];
if ([[UIApplication sharedApplication] canOpenURL:mailURL]) {
[[UIApplication sharedApplication] openURL:mailURL];
}

NSString *recipients = @"mailto:[email protected][email protected],[email protected]&subject=Hello from California!";
NSString *body = @"&body=It is raining in sunny California!";
NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];

func openMailApp() {
let toEmail = "[email protected]"
let subject = "Test email".stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet()
let body = "Just testing ...".stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet()
if let
urlString = ("mailto:\(toEmail)?subject=\(subject)&body=\(body)")),
url = NSURL(string:urlString) {
UIApplication.sharedApplication().openURL(url)
}
}

let subject = "Test email".addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
let body = "Just testing ...".addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
if let
urlString = "mailto:\(toEmail)?subject=\(subject)&body=\(body)",
url = URL(string:urlString) {
UIApplication.shared().openURL(url)
}
}

Since the only way to launch other applications is by using their URL schemes, the only way to open mail is by using the mailto: scheme. Which, unfortunately for your case, will always open the compose view.
由于启动其他应用程序的唯一方法是使用它们的 URL 方案，因此打开邮件的唯一方法是使用 mailto: 方案。不幸的是，对于您的情况，这将始终打开撰写视图。

You can open the mail app without using opening the compose view by using the url scheme message://
您可以使用 url 方案打开邮件应用程序，而无需打开撰写视图 message://

Run your app on a real device and call
在真实设备上运行您的应用程序并调用
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"[email protected]"]];
Note, that this line takes no effect on simulator.
请注意，此行对模拟器没有影响。

You can launch any app on iOS if you know its URL scheme. Don't know that the Mail app scheme is public, but you can be sneaky and try this:
如果您知道其 URL 方案，您可以在 iOS 上启动任何应用程序。不知道 Mail 应用程序方案是公开的，但你可以偷偷摸摸地试试这个：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"message:message-id"]];
Props to Farhad Noorzay for clueing me into this. It's some bit of reverse engineering the Mail app API. More info here: https://medium.com/@vijayssundaram/how-to-deep-link-to-ios-7-mail-6c212bc79bd9

Expanding on Amit's answer: This will launch the mail app, with a new email started. Just edit the strings to change how the new email begins.
扩展 Amit 的回答：这将启动邮件应用程序，并启动一封新电子邮件。只需编辑字符串即可更改新电子邮件的开始方式。
//put email info here:
NSString *toEmail=@"[email protected]";
NSString *subject=@"The subject!";
NSString *body = @"It is raining in sunny California!";
//opens mail app with new email started
NSString *email = [NSString stringWithFormat:@"mailto:%@?subject=%@&body=%@", toEmail,subject,body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];

If you are using Xamarin to developer an iOS application, here is the C# equivalent to open the mail application composer view:
如果您使用 Xamarin 开发 iOS 应用程序，这里是 C# 等效于打开邮件应用程序编辑器视图：
string email = "[email protected]";
NSUrl url = new NSUrl(string.Format(@"mailto:{0}", email));
UIApplication.SharedApplication.OpenUrl(url);

Swift 4 / 5 to open default Mail App without compose view. If Mail app is removed, it automatically shows UIAlert with options to redownload app :)
Swift 4 / 5 无需撰写视图即可打开默认邮件应用程序。如果邮件应用程序被删除，它会自动显示 UIAlert 和重新下载应用程序的选项:)
UIApplication.shared.open(URL(string: "message:")!, options: [:], completionHandler: nil)
