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.
