The Code
Play the video to get a step by step walkthrough and all code can be copy and pasted |
1.新建立一个项目,view based application(with storyboard.ARC)
2.需要引入UIMessage Library (Build Phases => Link Binary With Libraries => +(添加) => MessageUI.framework(可以搜索查找))
3.编辑ViewController.h文件
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
@interface ViewController : UIViewController <MFMailComposeViewControllerDelegate>
-(IBAction)sendMail:(id)sender;
@end
4.在MainStoryboard.storyboard文件中添加一个Round Rect Button ，关联到sendMail 函数。
5.在ViewController.m文件中添加如下方法
-(IBAction)sendMail:(id)sender
{
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
mail.mailComposeDelegate = self;
[mail setSubject:@"Hi here is Subject!"];
NSArray *toRecipients = [NSArray arrayWithObjects:@"[email protected]", nil];
[mail setToRecipients:toRecipients];
[mail setCcRecipients:toRecipients];
NSString *emailBody = @"This is a test email !";
[mail setMessageBody:emailBody isHTML:NO];
mail.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:mail animated:YES];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"ERROR" message:@"Email is not supported on your device" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: nil];
[alert show];
}
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(@"Cancelled");
break;
case MFMailComposeResultSaved:
NSLog(@"Message saved in drafts folder");
break;
case MFMailComposeResultSent:
NSLog(@"Message is sent");
break;
case MFMailComposeResultFailed:
NSLog(@"Message not sent due to error");
break;
default:
NSLog(@"Mail not sent");
break;
}
[self dismissModalViewControllerAnimated:YES];
}
