iOS通過html模版實現富文字編輯
在iOS開發中，常常會遇到一些富文字編輯，如新聞，公告等，NSMutableAttributedString又有一定的侷限性，所以我想到用html 模版去載入富文字頁面，根據所需要的格式，去構建相應的html介面。一個簡單的html模版如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet"href="mystyle.css"type="text/css"
<style type="text/css">
.sourceAndTime{
width:100%;
font-size:12pt;
line-height:40px;
color:#1b6761;
padding-right:8px;
padding-left:8px;
}
#news_title{
font-weight:bold;
font-size:20pt!important;
padding-right:8px;
padding-left:8px;
color:#57918b
}
#container{
font-size:$contentfontsize;
text-indent:1em;
padding-right:8px
padding-left:8px;
}
</style>
</head>
<body style="margin-left:10px;border: 0;">
<div >
<div id="news_title">$title</div>
<div class='sourceAndTime'>
<span>
<span style="padding-right:10px; float: right" >$source</span>
</div>
</div>
<div style="width: 100%;margin: 0 auto;height: auto;" >
<p style="text-align: center">
<img src=$imgSrcstyle="width: 50%;height:auto" />
</p>
</div>
<div id="container">$content</div>
<br/><br/><br/><br/>
</body>
</html>
在模版中預留相應的唯一標誌符，如$imgSrc等，然後在iOS端將這個html模版轉換為一個字串，然後再去替代這個字串內的那些唯一標誌符，具體iOS程式碼如下：NSString *path = [[NSBundle mainBundle] pathForResource:@"news_detail" ofType:@"html"];
_webString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
_webString = [_webString stringByReplacingOccurrencesOfString:@"$title"withString:[_titleArray objectAtIndex:indexPath.row]];
_webString = [_webString stringByReplacingOccurrencesOfString:@"$time" withString:[CNotificationVC TimeformatFromSeconds:[[ _timeArray objectAtIndex:indexPath.row] longLongValue]]];
_webString = [_webString stringByReplacingOccurrencesOfString:@"$imgSrc"withString:[_imageArray objectAtIndex:indexPath.row]];
_webString = [_webString stringByReplacingOccurrencesOfString:@"$content"withString:[_contentArray objectAtIndex:indexPath.row]];
_webString = [_webString stringByReplacingOccurrencesOfString:@"$source" withString:[_adminArray objectAtIndex:indexPath.row]];
UIWebView *webView = [[UIWebViewalloc]initWithFrame:CGRectMake(0,64, self.view.frame.size.width,self.view.frame.size.height)];
webView.delegate =self;
[webView setBackgroundColor:[UIColorclearColor]];
[webView setOpaque:NO];
[webView loadHTMLString:_webStrbaseURL:[NSURLfileURLWithPath:[[NSBundlemainBundle] pathForResource:@"news_detail"ofType:@"html"]]];
[self.viewaddSubview:webView];
具體步驟就是如此，希望對大家有所幫助
