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 = http://www.mamicode.com/[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;
