IOS发送电子邮件
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;@end
5、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
