简介
我们可以使用IOS设备中的电子邮件应用程序发送电子邮件。
实例步骤
1、创建一个简单的View based application
2、选择项目文件，然后选择目标，然后添加MessageUI.framework
3、在ViewController.xib中添加一个按钮，创建用于发送电子邮件的操作（action）
4、更新ViewController.h,如下所示
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
@interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>
{
MFMailComposeViewController *mailComposer;
}
-(IBAction)sendMail:(id)sender;
@end5、如下所示，更新ViewController.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)sendMail:(id)sender{
mailComposer = [[MFMailComposeViewController alloc]init];
mailComposer.mailComposeDelegate = self;
[mailComposer setSubject:@"Test mail"];
[mailComposer setMessageBody:@"Testing message
for the test mail" isHTML:NO];
[self presentModalViewController:mailComposer animated:YES];
}
#pragma mark - mail compose delegate
-(void)mailComposeController:(MFMailComposeViewController *)controller
didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
if (result) {
NSLog(@"Result : %d",result);
}
if (error) {
NSLog(@"Error : %@",error);
}
[self dismissModalViewControllerAnimated:YES];
}
@end输出
当运行该应用程序，会看如下的输出结果
当点击send email发送按钮后，可以看到如下结果：
