iOS Youtube Embedded video playlists

I'm having an issue embedding youtube videos into my iOS 6.0+ app in a UIWebView. Some of my playlist URLs work while others don't. The ones that don't work simply show a black box in the UIWebView with the appropriate title..but I can't hit play in the UIWebView to start the video.

Example of one that works: http://www.youtube.com/embed/videoseries?list=PLaLpP50ifUEi3z0IXMuc5EbxChfjj0YCX

Doesn't work: http://www.youtube.com/embed/videoseries?list=PLaLpP50ifUEhBzltdYTk63BNyVXx53bvj

However, both load properly in a browser.

My embedded NSString is

    NSString *embedHTML =[NSString stringWithFormat:@"\
                          <html><head>\
                          <style type=\"text/css\">\
                          body {\
                          background-color: transparent;\
                          color: blue;\
                          }\
                          </style>\
                          </head><body style=\"margin:0\">\
                          <iframe height=\"200\" width=\"300\" src=\"%@\"></iframe>\
                          </body></html>", url];

which I populate with the URL using:

[self.webView loadHTMLString:self.embedHTML baseURL:nil];

Why does this work for some playlist videos and not others?

Thanks!

Solution

Not shure if its exactly the same issue but since last week no playlist will work on iOS (iPhone,iPad) (embedded on a normal webpage) occurs with both iOS6 and iOS7.

see my post:

Playlist (embedded ) broken on iOS

They still work in all desktop-browsers.

Single videos will work...maybe that is why your 1st example still works cause its not a real playlist (?)...since it has only one video in it.

Its a bug @ youtube ... their only reply till now (@google api groups) was "its filed" which ofcourse is nothing ...they could just as well have said "its not filed" since "filed" means nothing ..they should for a start confirm that this is a bug ...next they should mention if and when its going to be solved.

Not shure but you may want to add/change a tag ( youtube-api ) not just "youtube" to your first post (if you still can).
