我正在開發一個iOS應用程序,它將一個CSS樣式表的HTML字符串的內容加載到UIWebView中,但是當我使用百分比'%'來定義圖像的寬度。它只是不起作用!iOS UIWebView,CSS&和百分比
- (void) loadHTMLContent {
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
textFontSize = 120;
NSString *imggt;
if (item.imggt)
imggt = [NSString stringWithFormat:@"<br /><img src='%@' />",item.imggt];
else
imggt = @"";
NSString *cssCode = [NSString stringWithFormat:@" \n"
"body{ font-family: Georgia; color: #333; margin: 0; padding: 0; line-height: 1.2em; } \n"
"h4, h3, h5{ margin: 0 0 5px 0; padding: 0em; text-shadow: 2px 2px 2px rgba(255, 255, 255, 0.8); } \n"
"h3{ font-family: Helvetica; font-size: 1.2em; letter-spacing: -1px; } \n"
"h3, #autor { color: #00365B; } \n"
"h4,h5{ font-weight: normal; font-size: 0.75em; }\n"
"h4{ color: #0069AA; } \n"
"h5{ text-align:justify; } \n"
"#zigzag { height:15px; background-image:url('zigzag.png');background-repeat:repeat-x; }\n"
"#destacados, #cuerpo{ padding: 0 10px; } \n"
"#destacados{ background-image:url('fndNoticia.png'); padding-bottom: 29px; margin-bottom: 0px; } \n"
"#destacados img { width: 97%; text-align:center; margin: 0 auto; border: 8px solid #FFF; } \n"
"#fecha_autor{ font-size: 0.75em; border-bottom: 1px solid #D7D7D7; height: 20px; padding-bottom: 8px; margin: 13px 0; } \n"
"#fecha{ color: #666;} \n"
"#autor{ float: right; } \n"
"#texto{ font-size: 0.80em; line-height: 1.2em; text-align:justify; } \n"];
NSString *htmlCode = [NSString stringWithFormat:@" \n"
"<html> \n"
" <head> \n"
" <title></title> \n"
" <style>%@</style></head> \n" //CSS
" <body> \n"
" <div id='destacados'> \n"
" <br /><h4>%@</h4> \n" //Category
" <h3>%@</h3> \n" //Title
" <h5>%@</h5>%@ \n" //Subtitle & Imggt in HTML
" </div> \n"
" <div id='zigzag'> </div> \n"
" <div id='cuerpo'> \n"
" <div id='fecha_autor'> \n"
" <span id='fecha'>%@</span> \n" //Date
" <span id='author'>%@</span> \n" //Author
" </div> \n"
" <div id='texto'>%@</div> \n"
" </div> \n"
" %@ \n" //Nielsen code
" </body> \n"
"</html> \n",cssCode,item.category,item.title,item.subtitle,imggt,item.pubDate,item.author,[item.text stringByReplacingOccurrencesOfString:@"[br]" withString:@"<br />"],[AppStaticData getNielsenSiteCensusHTMLImageOfArticle:item.url]];
[webView loadHTMLString:htmlCode baseURL:baseURL];
}
上的瀏覽器測試的CSS & HTML代碼的工作:
這個問題似乎是在這裏:
"#destacados img { width: 97%; text-align:center; margin: 0 auto; border: 8px solid #FFF; } \n"
看來,我不能用百分比來設置圖像的值。爲什麼?還有其他方法可以將原始圖像相對於容器大小進行縮放嗎?
'你必須在你的css代碼中跳過'%' - 這是我錯過的部分。謝謝。 – kaczor1984
