iPhone SDK录制视频然后通过电子邮件发送

Question

I was wondering if someone could show me how to record video and add it as attachment to mail composer in IOS. The more specific the better. Thanks.

Answer 1

Check this thread for capturing video programatically Basic description on how to record video in iOs 4

Check this tutorial about mail composer for iOS http://www.iostipsandtricks.com/using-apples-mail-composer/

Mail composer only supports images as direct attachments and other formats are needed to be added as nsdata

Send a file as attachment in objective c

PS : If you ask questions without googling people will probably down-vote it.

.h file

#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#import <MobileCoreServices/MobileCoreServices.h>

@interface ViewController : UIViewController <MFMailComposeViewControllerDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{
    UIImagePickerController *imagePicker;
    NSURL *videoURL;
}

-(IBAction)submitVideo;

.m file

- (void)viewDidLoad

    [super viewDidLoad];

    //set image picker
    imagePicker = [[UIImagePickerController alloc]init];
    NSArray *mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
    imagePicker.mediaTypes = [mediaTypes filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(SELF contains %@)", @"movie"]];
    imagePicker.delegate = self;
    imagePicker.videoMaximumDuration = 60.0;
    imagePicker.allowsEditing = YES;
    [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}

-(IBAction)submitVideo
{
    [self presentViewController:imagePicker animated:YES completion:nil];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

    videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
    NSLog(@"movie captured %@", info);

    [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(sendMail) userInfo:nil repeats:NO];

}


-(void)sendMail

    if ([MFMailComposeViewController canSendMail])
