问题描述

我想在我的应用中播放Youtube视频。所以,我写了下面的代码:

  NSString * embedHTML = @\ 
< html>< head> ; \
< style type = \text / css \> \
body {\
background-color:transparent; \
color :white; \
} \
< / style> \
< / head>< body style = \margin:0 \> \
width = \\ \\%0.0f \height = \%0.0f \>< / embed> \
< / body>< / html>;

NSString * html = [NSString stringWithFormat:embedHTML,videoURL,self.view.frame.size.width,self.view.frame.size.height];

[videoView loadHTMLString:html baseURL:nil];

videoView是一个UIWebView。这工作很好,直到后来,视图什么也没有显示。只是一个空白的白色视图。我得到这个日志:

  *** WebKit丢弃异常:< NSRangeException> ***  -  [__ NSCFString substringToIndex:]:范围或索引超出范围


解决方案

使用:



http://www.youtube.com/v/XXXXXXX



而不是:

http://www.youtube.com/watch?v = XXXXXXX

I want to play a Youtube video in my app. So, I wrote the following code

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, videoURL, self.view.frame.size.width, self.view.frame.size.height];

[videoView loadHTMLString:html baseURL:nil];

The videoView is a UIWebView. This was working just fine until later, the view shows nothing. Just a blank white view. And I got this log:

*** WebKit discarding exception: <NSRangeException> *** -[__NSCFString substringToIndex:]: Range or index out of bounds
解决方案

Use:

http://www.youtube.com/v/XXXXXXX

instead of:

http://www.youtube.com/watch?v=XXXXXXX
