如何在iOS的whatsapp上分享视频？

Question

我想在whatsapp上共享视频，但是我遇到savePath nil错误。

我使用以下代码：

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

我的错误在哪里？

Answer 1

这是Swift版本：

func sendVideo(videoName: String, senderView: UIView) {

    let path = NSBundle.mainBundle().pathForResource(videoName, ofType:"m4v")! 
    let fileUrl = NSURL(fileURLWithPath: path)! 

    docController = UIDocumentInteractionController(URL: fileUrl) 
    docController.UTI = "net.whatsapp.movie"
    docController.presentOpenInMenuFromRect(CGRectZero, inView: senderView, animated: true)

}

Answer 2

参考： 在iOS应用中通过WhatsApp共享图像/文本 // http://www.whatsapp.com/faq/zh/iphone/23559013

//---NEXT LINE OF CODE IS OPTIONAL AND NOT RECOMMENDED, BUT YOU CAN USE IT TO TEST TO SEE IF THEY HAVE THE WHATSAPP INSTALLED
//    if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){
NSString    * savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wam"];

savePath = [[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"m4v"];


_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
_documentInteractionController.UTI = @"net.whatsapp.movie";
_documentInteractionController.delegate = (id)self;

[_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];
