HTML没有加载CSS文件

我完全不知道为什么这不起作用.由于某些原因,HTML文件似乎无法加载CSS,即使两者都在同一目录中.知道可能是什么问题吗？

的index.html

<!DOCTYPE html>
<html>
<head>
<title>Home Page</title>
<link rel="stylesheet" href="style.css" media="screen" />
<meta name="viewport" content="width=1100">
</head>
<body>
<div id="main"> Hello </div>
</body>
</html>

style.css文件

body{
    background-color: #F9F9F9;
    background-image: url(images/bg3.png);
    background-position: center top;
    background-repeat: repeat;
    text-shadow: #FFFFFF 0px 1px 0px;
    font-family: "Georgia", "Times", serif;
    -webkit-font-smoothing: antialiased;
}

a{
    text-decoration: none;
}

#main{
    margin: 50px auto 50px auto;
    width: 1000px;
    min-height: 500px;
    padding: 0px 20px 0px 20px;
}

以上不起作用.在index.html中添加内联的css工作正常

<!DOCTYPE html>
<html>
<head>
<title>Homepage</title>
<style type="text/css" media="screen">
    body {
        background-color: #F9F9F9; …

iOS6上的YouTube视频播放功能已损坏(在iOS5上正常运行)

在我的应用程序中,我有一个按钮,当按下该按钮时,可以让您观看YouTube视频(电影预告片).在应用程序内,没有启动safari.您可以在下面看到代码段.这个代码在iOS5下运行正常.但是,在iOS 6中,findButtonInView中的UIButton始终为nil.任何想法可能是什么原因？

youtubeWebView.delegate = self;
youtubeWebView.backgroundColor = [UIColor clearColor];

NSString* embedHTML = @" <html><head> <style type=\"text/css\"> body {background-color: transparent;  color: white; }</style></head><body style=\"margin:0\"><embed id=\"yt\" src=\"%@?version=3&app=youtube_gdata\" type=\"application/x-shockwave-flash\"width=\"%0.0f\" height=\"%0.0f\"></embed></body></html>";

NSURL *movieTrailer;

if(tmdbMovie) movieTrailer = tmdbMovie.trailer;

else movieTrailer = [NSURL URLWithString:movie.trailerURLString];

NSString *html = [NSString stringWithFormat:embedHTML,
                                            movieTrailer,
                                            youtubeWebView.frame.size.width,
                                            youtubeWebView.frame.size.height];

[youtubeWebView loadHTMLString:html baseURL:nil];

[self addSubview:youtubeWebView];


- (void)webViewDidFinishLoad:(UIWebView *)_webView {

    isWatchTrailerBusy = NO;

    [manager displayNetworkActivityIndicator:NO];

    //stop the activity indicator and enable the button

     UIButton *b = [self findButtonInView:_webView];

    //TODO this returns null in case of …

UIView的animateWithDuration延迟不延迟动画

我试图在翻转动画发生的标签上执行动画,在完成后和延迟之后,标签的文本会发生变化.

似乎延迟从未发生过.翻转完成后文本会立即更改,尽管我在完成块中使用 UIView animateWithDuration:0.5 延迟:4.0.如果相反,我performSelector在completion block(注释声明)中使用延迟,它按预期工作.知道为什么延迟值被忽略了吗？

- (void) flipShapeWithText:(NSString *)text {

    [UIView transitionWithView:someLabel duration:0.15 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
        someLabel.text = text;  
    }completion:^ (BOOL finished){
//        [self performSelector:@selector(updateLabelText:) withObject: @"New Text" afterDelay:4.0];
    [UIView animateWithDuration:0.5
                              delay:4.0
                            options: UIViewAnimationOptionTransitionCrossDissolve
                         animations:^{
                             currentShapeNameLabel.text =  @"New Text" ;}
                         completion:nil];
    }];
}

UISegmentedControl和UIAppearance的奇怪行为

我通过app委托中的这些语句设置分段控件的外观.

    [[UISegmentedControl appearance] setBackgroundImage:[[UIImage imageNamed:@"segmentation_normal.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0 , 0, 0)] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [[UISegmentedControl appearance] setBackgroundImage:[[UIImage imageNamed:@"segmentation_selected.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0 , 0, 0)] 
        forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

    [[UISegmentedControl appearance] setDividerImage:[UIImage imageNamed:@"segmentation_divider_NormalNormal.png"]   forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [[UISegmentedControl appearance] setDividerImage:[UIImage imageNamed:@"segmentation_divider_NormalSelected.png"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    [[UISegmentedControl appearance] setDividerImage:[UIImage imageNamed:@"segmentation_divider_SelectedNormal.png"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

结果很好.当我选择任何段时,背景和分隔线设置正确(当应用程序首次启动时,默认选择订单段).如下所示,当我选择Release段时,一切看起来都很好.
