先用Storyboard拖四个按钮，与对应的controller类关联属性和方法

---------------------------------------------------------------------------------------------------------------发送邮件：--------------------------------------------------------------------------------------------------

导入MessageUI.framework

遵循MFMailComposeViewControllerDelegate协议

//发送邮件- (IBAction)mailDelivery:(id)sender {    //  判断设备是否是否可以发送邮件    //  NSClassFromString简单介绍http://blog.csdn.net/cml_cml/article/details/37659421    Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));    NSString * feedbackMsg;    //判断当前版本是否支持邮件发送    if (!mailClass) {             feedbackMsg = @"当前系统版本不支持应用内发送邮件功能";        UIAlertView *alertView =        [[UIAlertView alloc] initWithTitle:@"提示"                                   message:feedbackMsg                                  delegate:nil                         cancelButtonTitle:@"确定"                         otherButtonTitles:nil];        [alertView show];       }else if(![mailClass canSendMail])    {        //  判断是否设置邮件账户        feedbackMsg = @"您没有设置邮件账户";        UIAlertView *alertView =        [[UIAlertView alloc] initWithTitle:@"提示"                                   message:feedbackMsg                                  delegate:nil                         cancelButtonTitle:@"确定"                         otherButtonTitles:nil];               [alertView show];          }else{// 发送邮件        [self sendFeedBackMail];    }}-(void)sendFeedBackMail{    //是否创建邮件    BOOL judge = [MFMailComposeViewController canSendMail];    if (judge) {        //创建邮件        MFMailComposeViewController *pick = [[MFMailComposeViewController alloc]init];        //标题        [pick setSubject:@"意见反馈"];        //邮件地址        NSArray *address = [NSArray arrayWithObject:@"请填上自己的邮箱"];        [pick setToRecipients:address];        //内容        NSString *message = @"你好!";//  设置代理        pick.mailComposeDelegate = self;        [pick setMessageBody:message isHTML:NO];        //返回        [self presentViewController:pick animated:YES completion:NULL];    }}//代理方法-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{    NSString *title = @"邮件发送提醒";    NSString *msg;    switch (result) {        case MFMailComposeResultCancelled:            msg = @"邮件取消!";            [self alertWithTitle:title msg:msg];            break;        case MFMailComposeResultSaved:            msg = @"邮件保存成功!";            [self alertWithTitle:title msg:msg];            break;        case MFMailComposeResultSent:            msg = @"邮件发送成功!";            [self alertWithTitle:title msg:msg];            break;                    case MFMailComposeResultFailed:            msg =@"邮件发送失败!";            [self alertWithTitle:title msg:msg];            break;    }    [self dismissViewControllerAnimated:YES completion:NULL];}- (void)alertWithTitle:(NSString *)_title_ msg:(NSString *)msg{    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:_title_                                                    message:msg                                                   delegate:nil                                          cancelButtonTitle:@"好"                                          otherButtonTitles:nil];    [alert show];}

---------------------------------------------------------------------------------------------------------------发送短信------------------------------------------------------------------------------------------------------

导入MessageUI.framework

遵循MFMessageComposeViewControllerDelegate协议

//发送短信- (IBAction)noteDelivery:(id)sender {    BOOL judge = [MFMessageComposeViewController canSendText];    if (judge) {        MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc]init];        picker.messageComposeDelegate = self;        //收件人        picker.recipients = @[@"186*******"];        //内容        picker.body = @"很高兴见到你!";        [self presentViewController:picker animated:YES completion:nil];    }else    {               UIAlertView *alertView =        [[UIAlertView alloc] initWithTitle:@"提示"                                   message:@"系统不具备此项功能!"                                  delegate:nil                         cancelButtonTitle:@"确定"                         otherButtonTitles:nil];                [alertView show];            }}#pragma mark--------------发送短信代理方法-----------------(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{    NSString *title = @"邮件发送提醒";    NSString *msg;    switch (result) {        case MessageComposeResultCancelled:            msg = @"短信取消!";            [self alertWithTitle:title msg:msg];            break;        case MessageComposeResultSent:            msg = @"短信成功发送!";            [self alertWithTitle:title msg:msg];            break;        case MessageComposeResultFailed:            msg = @"短信发送失败!";            [self alertWithTitle:title msg:msg];            break;           }    [self dismissViewControllerAnimated:YES completion:nil];}

//  alertWithTitle：msg：方法与邮箱的一样

---------------------------------------------------------------------------------------------------------------相机使用------------------------------------------------------------------------------------------------------

导入UIImagePickerControllerDelegate

//使用相机功能- (IBAction)useTheCamera:(id)sender {        // UIImagePickerControllerCameraDeviceRear 后置摄像头    // UIImagePickerControllerCameraDeviceFront 前置摄像头    BOOL isCamera = [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear];    if (!isCamera) {        NSLog(@"没有摄像头");        return ;    }        UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;    imagePicker.delegate = self;    // 编辑模式    imagePicker.allowsEditing = YES;    [self  presentViewController:imagePicker animated:YES completion:nil];}//使用图库- (IBAction)galleryUse:(id)sender {    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;    imagePicker.delegate = self;    [self  presentViewController:imagePicker animated:YES completion:^{    }];}使用UIImagePickerControllerDelegateUINavigationControllerDelegate代理方法#pragma mark--------------使用相机----------------// 选中照片- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{    NSLog(@"%@", info);    UIImageView  *imageView = (UIImageView *)[self.view viewWithTag:101];    // UIImagePickerControllerOriginalImage 原始图片    // UIImagePickerControllerEditedImage 编辑后图片    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];    imageView.image = image;    [picker dismissViewControllerAnimated:YES completion:NULL];    }// 取消相册- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {    [picker dismissViewControllerAnimated:YES completion:NULL];   }
