Objective C: Send email without leaving app
提问by Chris
How do I send an email within an app without leaving the app.
如何在不离开应用程序的情况下在应用程序内发送电子邮件。
This works:
这有效：
-(void) sendEmailTo:(NSString *)to withSubject:(NSString *)subject withBody:(NSString *)body {
NSString *mailString = [NSString stringWithFormat:@"mailto:?to=%@&subject=%@&body=%@",
[to stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
[subject stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
[body stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];
}
but goes to the mail app to send. Is there a way to do this without leaving the app?
但转到邮件应用程序发送。有没有办法在不离开应用程序的情况下做到这一点？

Yes. Use the MFMailComposeViewController.
是的。使用MFMailComposeViewController。
// From within your active view controller
if([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
mailCont.mailComposeDelegate = self;
[mailCont setSubject:@"yo!"];
[mailCont setToRecipients:[NSArray arrayWithObject:@"[email protected]"]];
[mailCont setMessageBody:@"Don't ever want to give you up" isHTML:NO];
[self presentViewController:mailCont animated:YES completion:nil];
}
// Then implement the delegate method
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self dismissViewControllerAnimated:YES completion:nil];
}

Add MessageUI framework:
- Click on the project
- Select "Build Phases"
- Expand "Link Binary With Libraries"
- Click "+" and type "Message" to find "MessageUI" framework, then add.
In current view controller add import and implement a protocol:
#import <MessageUI/MessageUI.h> #import <MessageUI/MFMailComposeViewController.h> @interface MyViewController : UIViewController<MFMailComposeViewControllerDelegate>
添加 MessageUI 框架：
- 点击项目
- 选择“构建阶段”
- 展开“链接二进制与库”
- 点击“+”并输入“Message”找到“MessageUI”框架，然后添加。
在当前视图控制器中添加导入并实现一个协议：
#import <MessageUI/MessageUI.h> #import <MessageUI/MFMailComposeViewController.h> @interface MyViewController : UIViewController<MFMailComposeViewControllerDelegate>
Add methods:
添加方法：
-(void)sendEmail {
// From within your active view controller
if([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
mailCont.mailComposeDelegate = self; // Required to invoke mailComposeController when send
[mailCont setSubject:@"Email subject"];
[mailCont setToRecipients:[NSArray arrayWithObject:@"[email protected]"]];
[mailCont setMessageBody:@"Email message" isHTML:NO];
[self presentViewController:mailCont animated:YES completion:nil];
}
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[controller dismissViewControllerAnimated:YES completion:nil];
}

Updated for iOS 6. Please note that this uses ARC and does not use the deprecated modal view presentation:
为 iOS 6 更新。请注意，这使用 ARC 并且不使用已弃用的模态视图演示：
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
@interface MyViewController : UIViewController<MFMailComposeViewControllerDelegate>
And then the code to present the email screen:
然后是显示电子邮件屏幕的代码：
- (IBAction)emailButtonPushed:(id)sender {
if([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
mailCont.mailComposeDelegate = self;
[mailCont setSubject:@"Your email"];
[mailCont setMessageBody:[@"Your body for this message is " stringByAppendingString:@" this is awesome"] isHTML:NO];
[self presentViewController:mailCont animated:YES completion:nil];
}
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
//handle any error
[controller dismissViewControllerAnimated:YES completion:nil];
}
