我通过在互联网上找到的代码片段,嵌入了一个来自YouTube的视频,这是我使用的代码:
@interface FirstViewController (Private)
- (void)embedYouTube:(NSString *)urlString frame:(CGRect)frame;
@end
@implementation FirstViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self embedYouTube:@"http://www.youtube.com/watch?v=l3Iwh5hqbyE" frame:CGRectMake(20, 20, 100, 100)];
}
- (void)embedYouTube:(NSString *)urlString 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, urlString, frame.size.width, frame.size.height];
UIWebView *videoView = [[UIWebView alloc] initWithFrame:frame];
[videoView loadHTMLString:html baseURL:nil];
[self.view addSubview:videoView];
[videoView release];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
它编译正确,但当我打开它时,我看到一个白色的框架位置不正确,这是代码创建的。我有两个问题:
我如何知道视频是否会播放,因为它只是一个纯白色的框,模拟器可以从YouTube播放视频吗?
我如何调整此框的位置?
