ios实现发邮件
1.首先添加 MessageUI.framework 框架
2. 引入框架
在类的头部
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
3. 实现接口
<MFMailComposeViewControllerDelegate>
4. 当点击一个button 跳转到发邮件的页面 调用我们发邮件
发邮件是有两种方式 :
1. 当你的设备支持的时候 the current device is configured for sending emails
我们使用一下的tool methods 中的displayComposerSheet 方法来发送邮件(其中使用了apple 集成好的 邮件picker -- MFMailComposeViewController) 在这里 我们将这个picker 看做是一个 模式视图 ModalViewController 推出了
2. 当设备不支持的时候 我们采用
launchMailAppOnDevice 方法发送 ( 采用打开一个url地址的 方式来发) ok..
-----点击按钮出发的方法
- (IBAction)contactBtnPressed:(id)sender {
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
// We must always check whether the current device is configured for sending emails
if ([mailClass canSendMail])
{
[self displayComposerSheet];
}
else
{
[selflaunchMailAppOnDevice];
}
}
else
{
[selflaunchMailAppOnDevice];
}
}
----- tool Methods 工具方法
// 1. Launches the Mail application on the device.
-(void)launchMailAppOnDevice
{
NSString *recipients = @"mailto:maxwellsoftware@gmail.com&subject=Pocket Truth or Dare Support";
NSString *body = @"&body=email body!";
NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplicationsharedApplication] openURL:[NSURLURLWithString:email]];
}
// 2. Displays an email composition interface inside the application. Populates all the Mail fields.
-(void)displayComposerSheet
{
MFMailComposeViewController *picker = [[MFMailComposeViewControlleralloc] init];/*MFMailComposeViewController邮件发送选择器*/
picker.mailComposeDelegate = self;
[picker setSubject:@"Pocket Truth or Dare Support"];/*emailpicker标题主题行*/
// Custom NavgationBar background And set the backgroup picture
picker.navigationBar.tintColor = [UIColorcolorWithRed:209.0/255green:183.0/255blue:126.0/255alpha:1.0];
// picker.navigationBar.tintColor = [UIColor colorWithRed:178.0/255 green:173.0/255 blue:170.0/255 alpha:1.0];
if ([[[UIDevicecurrentDevice] systemVersion] floatValue] >= 5.0) {
[picker.navigationBarsetBackgroundImage:[UIImageimageNamed:@"nav_bg.png"] forBarMetrics:UIBarMetricsDefault];
}
// Set up recipients
NSArray *toRecipients = [NSArrayarrayWithObject:@"maxwellsoftware@gmail.com"];
[picker setToRecipients:toRecipients];
// Fill out the email body text
struct utsname device_info;
uname(&device_info);
NSString *emailBody = [NSString
stringWithFormat:@"Model: %s\nVersion: %@\nApp: %@\nFeedback here:\n",device_info.machine,
[[UIDevicecurrentDevice] systemVersion],/*设备系统环境*/
[[[NSBundlemainBundle] infoDictionary]
objectForKey:@"CFBundleShortVersionString"]];/**/
NSLog(@"ios 应用发布后 .app 应用文件路径::%@",[NSBundle mainBundle] );
NSLog(@"ios 应用发布后 .app 应用文件内 ::%@",[[NSBundle mainBundle] infoDictionary]);
[picker setMessageBody:emailBody isHTML:NO];
[selfpresentModalViewController:picker animated:YES];
[picker release];
}
// 3. 一个备用的方法
//- (void) alertWithTitle: (NSString *)_title_ msg: (NSString *)msg
//{
// UIAlertView *alert = [[UIAlertView alloc] initWithTitle:_title_
// message:msg
// delegate:nil
// cancelButtonTitle:@"Sure"
// otherButtonTitles:nil];
// [alert show];
// [alert release];
//}
----协议的委托方法
// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the message field with the result of the operation.
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
// NSString *title = @"Mail";
// NSString *msg;
// switch (result)
// {
// case MFMailComposeResultCancelled:
// msg = @"Mail canceled";//@"邮件发送取消";
// break;
// case MFMailComposeResultSaved:
// msg = @"Mail saved";//@"邮件保存成功";
// [self alertWithTitle:title msg:msg];
// break;
// case MFMailComposeResultSent:
// msg = @"Mail sent";//@"邮件发送成功";
// [self alertWithTitle:title msg:msg];
// break;
// case MFMailComposeResultFailed:
// msg = @"Mail failed";//@"邮件发送失败";
// [self alertWithTitle:title msg:msg];
// break;
// default:
// msg = @"Mail not sent";
// [self alertWithTitle:title msg:msg];
// break;
// }
[self dismissModalViewControllerAnimated:YES];
