调用摄像头拍照或者摄像,把获得的数据写入到文件
获取视频：
UIImagePickerController *picker = [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
委托代码：
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if([mediaType isEqualToString:@"public.movie"])
{
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSLog(@"found a video");
NSData *videoData = nil;
videoData = [NSData dataWithContentsOfURL:videoURL];
webData = [[NSMutableData alloc] init];
[webData appendData:videoData];
if (webData != nil) {
NSLog(@"SUCCESS!");
}
}
}
