Question

我正在尝试使用UIImagePickerController录制两个视频。一切正常，但录制第二个视频时，它似乎覆盖了第一个录制视频的路径我需要将两个视频上传到服务器，但第一个视频路径在上传和应用程序崩溃时为零。有没有办法在不同的路径上录制第二个视频？

视频路径如下：

/private/var/mobile/Containers/Data/Application/1465EC90-4B57-41FF-996E-0CCB7713ECE7/tmp/50332801315__A883E4DB-ED72-4D31-9564-22FB363779BD.MOV
/private/var/mobile/Containers/Data/Application/1465EC90-4B57-41FF-996E-0CCB7713ECE7/tmp/50332802324__F11733AD-EB62-426D-BA1C-7E87D2BF66D0.MOV

这是我的imagePicker委托代码：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {
    NSURL *videoUrl = (NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
    NSString *moviePath = [videoUrl path];

    if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
        UISaveVideoAtPathToSavedPhotosAlbum (moviePath, nil, nil, nil);
    }

    NSLog(@"videoUrl: %@", videoUrl);
    NSLog(@"moviePath: %@", moviePath);

    // self.moviePath_1 = @"";
    // self.moviePath_2 = @"";

    NSLog(@"picker.title: %@", picker.title);
    if ([picker.title isEqualToString:@"Video_1"]) {
        self.moviePath_1 = moviePath;
        self.video_1 = YES;
        NSLog(@"self.moviePath_1: %@", self.moviePath_1);
        self.video_1_Data = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:self.moviePath_1]];
        NSLog(@"Video_1 Size: %@",[NSByteCountFormatter stringFromByteCount:self.video_1_Data.length countStyle:NSByteCountFormatterCountStyleFile]);

        [self setupAndPlayback:@"Video_1"];

    } else {
        self.moviePath_2 = moviePath;
        self.video_2 = YES;
        NSLog(@"self.moviePath_2: %@", self.moviePath_2);
        self.video_2_Data = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:self.moviePath_2]];
        NSLog(@"Video_2 Size: %@",[NSByteCountFormatter stringFromByteCount:self.video_2_Data.length countStyle:NSByteCountFormatterCountStyleFile]);

        [self setupAndPlayback:@"Video_2"];

    }
}

[self dismissViewControllerAnimated:YES completion:nil];
}

将视频保存在不同的路径上。你正在克服这个问题发生的原因。添加时间戳或使用路径增加数字并保存。

 self.moviePath_1 = [NSString stringWithFormat: @"%@-%d.png", moviePath, num] ;
 num += 1; // for next time

使用UIImagePickerController进行第二次视频录制会覆盖第一次视频录制的路径
