MFMailComposeViewController发送邮件

1.iPhone API已经提供了系统写邮件界面的接口,使用MFMailComposeViewController，用来显示界面.

2.项目中需要添加MessageUi.framework。头文件加入MFMailComposeViewControllerDelegate。#import <MessageUI/MessageUI.h>

- (void)viewDidLoad

{

　　// 实例化按钮用来调用邮箱

　　UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];

　　button.frame = CGRectMake(0, 40, 320, 50);

　　[button setTitle: @"Mail" forState: UIControlStateNormal];

　　[button addTarget: self action: @selector(sendEmailAction) forControlEvents: UIControlEventTouchUpInside];

　　[self.view addSubview: button];

}

- (void)sendEmailAction

{

　　 Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));

if (mailClass != nil)

{

if ([mailClass canSendMail])

{

[self displayComposerSheet ];

}else{

[self launchMailAppOnDevice];

}

}else {

[self launchMailAppOnDevice];

}

}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result

{

// [self dismissModalViewControllerAnimated:YES];

[self dismissViewControllerAnimated:YES completion:nil];

　　NSString*msg;

　　switch (result) {

　　case MessageComposeResultCancelled:

　　　　msg = @"发送取消";

　　　　break;

　　case MessageComposeResultSent:

　　　　msg = @"发送成功";

　　　　break;

　　case MessageComposeResultFailed:

　　　　msg = @"发送失败";

　　　　break;

　　　　default:

　　　　break;

}

UIAlertView*alert = [[UIAlertView alloc] initWithTitle:nil

message:msg

delegate:nil

cancelButtonTitle:@"关闭"

otherButtonTitles:nil];

[alert show];

}

//email界面,界面添加于window上

-(void)displayComposerSheet

{

　　　　MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];

　　　　 [picker setAccessibilityLanguage:@"Chinese"];

if (!picker) {

　　 // 在设备还没有添加邮件账户的时候mailViewController为空，下面的present view controller会导致程序崩溃，这里要作出判断

　　  NSLog(@"设备还没有添加邮件账户");

　　return;

}

　　 picker.mailComposeDelegate = self;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 5.0) {

UIView *barBgV = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 44)];

barBgV.backgroundColor = [UIColor colorWithRed:55/255.0 green:60/255.0 blue:100/255.0 alpha:1.0];

UIImage *barBgImg = [Tool convertViewToImage:barBgV];

[[picker navigationBar] setBackgroundImage:barBgImg forBarMetrics:UIBarMetricsDefault];

}

// Set up recipients

　　　　　　NSArray *toRecipients = [NSArray arrayWithObject:staff.email];

　　　　　　[picker setToRecipients:toRecipients];

//    NSString *path = [[NSBundle mainBundle] pathForResource:@"Icon@2x.png"

//                                                     ofType:nil

//                                                inDirectory:nil];

//    　　　　NSData *myData = [NSData dataWithContentsOfFile:path];

//    　　　　[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"icon"];

　　　　[picker setMessageBody:nil isHTML:YES];

　　  [self presentViewController:picker animated:YES completion:^{

　　 picker.accessibilityElementsHidden = YES;

}];

　　// [self presentModalViewController:picker animated:YES];

}

//跳转到系统email界面

-(void)launchMailAppOnDevice

{

　　　　NSString *recipients = [NSString stringWithFormat:@"mailto:%@?&subject=",staff.email];

　　　　NSString *email = recipients;

　　　　email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

　　　　[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];

}

#pragma mark - 代理

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error

{

　　 //关闭邮件发送窗口

　　 [self dismissViewControllerAnimated:YES completion:nil];

　　 NSString *msg;

　　　　switch (result)

　　　　{

　　case MFMailComposeResultCancelled:

msg = @"用户取消编辑邮件";

　　　　break;

　　case MFMailComposeResultSaved:

msg = @"用户成功保存邮件";

　　　　break;

　　case MFMailComposeResultSent:

　　 msg = @"发送成功";

　　　　　　break;

　　case MFMailComposeResultFailed:

msg = @"用户试图保存或者发送邮件失败";

　　　　break;

　　　　default:

　　　　break;

}

[[[UIAlertView alloc]initWithTitle:nil message:msg delegate:nil cancelButtonTitle:@"关闭" otherButtonTitles:nil, nil]show];

}

设置中文：

1.可以在项目的list属性文件中设置Localization native development region的属性值  为：China；

2.可以在调用MFMailComposeViewController的xib中设置Localization(方法如下:找到对应xib文件,右击该文件选择Get Infoà [General选项卡下单击{add Localization}])如中文简体{zh_CN}

3.或者在自己手机：设置-->通用--->多语言环境-->语言--->简体中文；

General--->International-->Language--->简体中文;
