    Using this you can run youtube video in your view..

    UIWebView *videoView = [[UIWebView alloc] initWithFrame:self.view.bounds];

        NSString *strparse = [NSString stringWithFormat:@"http://www.youtube.com/watch?v=%@",youtubeVideoId];
        NSRange rng = [strparse rangeOfString: @"watch?v="];
        strparse = [strparse substringFromIndex:rng.location];
        rng = [strparse rangeOfString:@"&feature="];
    
    
        if (rng.length >0)
        {
            strparse = [strparse substringToIndex:rng.location];
        }
        strparse = [strparse stringByReplacingOccurrencesOfString:@"watch?v=" withString:@""];
        //http://www.youtube.com/embed/FJkiwbqlSy0
        NSString *youTubeVideoHTML =[NSString stringWithFormat:@"<!DOCTYPE html><html><head><style>body{margin:0px 0px 0px 0px; background:#1111}</style></head> <body> <div id=\"player\"></div> <script> var tag = document.createElement('script'); tag.src = \"http://www.youtube.com/player_api\"; var firstScriptTag = document.getElementsByTagName('script')[0]; firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); var player; function onYouTubePlayerAPIReady() { player = new YT.Player('player', { width:'%0.0f', height:'%0.0f', videoId:'%@', events: { 'onReady': onPlayerReady, 'onStateChange': onPlayerStateChange } });} function onPlayerReady(event) { event.target.playVideo(); } function onPlayerStateChange(event) {if(event.data === 0) {   event.target.destroy(); }}  </script> </body> </html>",0.0, 0.0,youtubeVideoId];
    
    
        videoView.scalesPageToFit=NO;
        videoView.mediaPlaybackRequiresUserAction=NO;
        videoView.backgroundColor = [UIColor clearColor];
        videoView.opaque= NO;
    
    
        [SharedObj showLoadingWithText:@""];
    
        [videoView loadHTMLString:youTubeVideoHTML baseURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.youtube.com/watch?v=%@",youtubeVideoId]]];
    
    
        [self.view addSubview:videoView];

    YouTube has made available a framework to save us from the hassle of using a web view directly. The framework is available at: https://github.com/youtube/youtube-ios-player-helper

    All you need to do is to create a YTPlayerView view, add it to the view hierarchy with the constraints you like and load the video. Like so:

        youTubePlayer = YTPlayerView()
        youTubePlayer!.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(youTubePlayer!)
        youTubePlayer!.pinAllAnchors(to: contentView)
        youTubePlayer!.load(withVideoId: url.youTubeVideoId()!)
    

    Note that pinAllAnchors and youTubeVideoId are helpers I created. They are not part of the framework.

    This is the tested code in IOS7 , its working fine

    [self embedYouTube:[self getYTUrlStr:@"https://www.youtube.com/watch?v=Zq4o_Ca14aw"] frame:CGRectMake(0,40,self.view.frame.size.width, self.view.frame.size.height-40)];
    
    
    - (NSString*)getYTUrlStr:(NSString*)url
    {
        if (url == nil)
            return nil;
    
        NSString *retVal = [url stringByReplacingOccurrencesOfString:@"watch?v=" withString:@"v/"];
    
        NSRange pos=[retVal rangeOfString:@"version"];
        if(pos.location == NSNotFound)
        {
            retVal = [retVal stringByAppendingString:@"?version=3&hl=en_EN"];
        }
        return retVal;
    }
    
    
    
    - (void)embedYouTube:(NSString*)url frame:(CGRect)frame {
    
        NSString* embedHTML = @"\
        <html><head>\
        <style type=\"text/css\">\
        body {\
        background-color: transparent;\
        color: white;\
        }\
        </style>\
        </head><body style=\"margin:0\">\
        <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \
        width=\"%0.0f\" height=\"%0.0f\"></embed>\
        </body></html>";
        NSString* html = [NSString stringWithFormat:embedHTML, url, frame.size.width, frame.size.height];
        if(videoView == nil) {
            videoView = [[UIWebView alloc] initWithFrame:frame];
            videoView.delegate=self;
            [self.view addSubview:videoView];
        }
    
    
        videoView.mediaPlaybackAllowsAirPlay=YES;
        videoView.allowsInlineMediaPlayback=YES;
        [videoView loadHTMLString:html baseURL:nil];
    
    }

    I used following way in my app and its working in both iOS6 and iOS 7. May be its works for you.

    NSString *youTubeID = [self extractYoutubeID:url];   // url is youtube url 
    NSString *embedHTML =[NSString stringWithFormat:@"\
                              <html><head>\
                              <style type=\"text/css\">\
                              body {\
                              background-color: #666666;\
                              padding:%f %f %f %f;\
                              color: blue;\
                              }\
                              </style>\
                              </head><body style=\"margin:0\">\
                              <iframe height=\"%f\" width=\"%f\" title=\"YouTube Video\" class=\"youtube-player\" src=\"http://www.youtube.com/embed/%@\" ></iframe>\
                              </body></html>",paddingTop,paddingRight,paddingBottom,paddingLeft,videoHeight,videoWidth,youTubeID];
    [self.webView loadHTMLString:embedHTML baseURL:nil];
    
    
    
    
    - (NSString *)extractYoutubeID:(NSString *)youtubeURL
        {
            //NSLog(@"youtube  %@",youtubeURL);
            NSError *error = NULL;
            NSString *regexString = @"(?<=v(=|/))([-a-zA-Z0-9_]+)|(?<=youtu.be/)([-a-zA-Z0-9_]+)";
            NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:regexString options:NSRegularExpressionCaseInsensitive error:&error];
            NSRange rangeOfFirstMatch = [regex rangeOfFirstMatchInString:youtubeURL options:0 range:NSMakeRange(0, [youtubeURL length])];
            if(!NSEqualRanges(rangeOfFirstMatch, NSMakeRange(NSNotFound, 0)))
            {
                NSString *substringForFirstMatch = [youtubeURL substringWithRange:rangeOfFirstMatch];
                return substringForFirstMatch;
            }
            return nil;
        }

    Try this:

    NSString* videoUrl = @"//www.youtube.com/embed/Of_hjbYCx4Y";
    if([videoUrl hasPrefix:@"//"]) {
        videoUrl = [NSString stringWithFormat:@"https:%@", videoUrl]; // or http
        // if its a local file add proper scheme like "file:///"
    }
    NSString* iframeWidth = @"100%";
    NSString* iframeHeight = @"240px";
    NSString *iframeHTML =[NSString stringWithFormat:@"<iframe width=\"%@\" height=\"%@\" src=\"%@\" frameborder=\"0\" allowfullscreen></iframe>", iframeWidth, iframeHeight, videoUrl];
    // you can directly use iframeHTML below or u can wrap it up in body and span tags and then use it if u need to add any extra stuff or customize the page itself
    [videoWebView loadHTMLString:htmlString baseURL:nil];
    

    Make sure of two things: Video url starts with http (proper scheme) and replace the /watch?v= with embed/ if u don't have it already in url. Check other answers given here to see how to do this. Hope it helps.
