iOS 无法使用 UIDocumentInteractionController 将视频分享到 Whatsapp

Question

它成功重定向到 Whatsapp app.There 没有预览帧，点击发送时，弹出错误消息“无法发送此视频。请选择其他视频。

这是我的代码。

- (void)shareVideo {
NSLog(@"[WhatsAppShare] sharing video");
//NSString *nativePath = [[NSString alloc] initWithCString:path encoding:NSASCIIStringEncoding];
NSString *nativePath=[[NSBundle mainBundle] pathForResource:@"video" ofType:@"mp4"];

// Save video to path in documents directory
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wam"];

if([[NSFileManager defaultManager] fileExistsAtPath:savePath]){
    if([[NSFileManager defaultManager] removeItemAtPath:savePath error:nil]){
        [self shareVideoAtNativePath:nativePath SavePath:savePath];
    }
} else {
    [self shareVideoAtNativePath:nativePath SavePath:savePath];
}}

- (void)shareVideoAtNativePath:(NSString*)nativePath SavePath:(NSString*)savePath{
NSError*error;
BOOL isSuccess=[[NSFileManager defaultManager] copyItemAtPath:nativePath toPath:savePath error:&error];
if(isSuccess){
    // Create interaction controller
    self.documentInteractionController          = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
    self.documentInteractionController.UTI      = @"net.whatsapp.movie";
    self.documentInteractionController.delegate = self;

    [self.documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 1, 1)
                                                           inView:[self view]
                                                         animated:YES];
} else{
    NSLog(@"error %@", error);
}
}

Answer 1

我们观察到了完全相同的问题。一切正常，直到最近更新了 WhatsApp。这可能是 WhatsApp 方面的错误。

以下是解决此问题的方法：

不要使用wam文件，直接使用mp4文件。所以在你的情况下，只需调用
```
[self shareVideoAtNativePath:nativePath SavePath:nativePath];
```

将 UTI 更改为 public Mpeg4：

self.documentInteractionController.UTI = @"public.mpeg-4";

这似乎解决了我们的问题。但是，有一个缺点，共享对话框现在包含许多其他可以打开 mp4 文件的apps/services。

Answer 2

我们遇到了完全相同的问题。

官方 .wam 格式仅在分享对话框中显示 WhatsApp，但无法转发视频。

使用 .m4v 格式对我们有用。与 WhatsApp 一起显示了更多选项（Open in WhatsApp 是我们想要的选项）。在将用户发送到共享对话框之前，我们显示一条警告说 "Please select Whatsapp on the next screen"。

文件格式：m4v

尿路感染：net.whatsapp.movie

请参考下面的工作代码：

 UIDocumentInteractionController *documentInteractionController;
    -----
    -----
 - (void)shareVideoViaWhatsApp:(NSURL*)url{    
        // Creating temp video to share specifically on whatsapp.   
        NSString *cachesFolder = [NSTemporaryDirectory() stringByAppendingPathComponent: [NSString stringWithFormat:@"video.m4v"]];
        NSURL *file = [NSURL fileURLWithPath:cachesFolder];
        [[NSData dataWithContentsOfURL:url] writeToURL:file options:NSDataWritingAtomic error:nil];

        documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL: file ];
        documentInteractionController.UTI = @"net.whatsapp.movie";

        documentInteractionController.delegate = self;
        [documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
 }

Answer 3

// In code Use share GIF and Video for WhatsApp....

  NSString    *savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wam"];
savePath = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"m4v"];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:_videourl];
_documentInteractionController.UTI = @"net.whatsapp.movie";
_documentInteractionController.delegate = (id)self;
[_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];
