iOS中的webView加载HTML_html/css_WEB-ITnose
在日常开发中,我们为了效率会用到很多很多的 WebView,比如在做某个明细页面的时候我们返回给你的可能是一个 html字符串,我们就需要将当前字符串展示到 webView上面,所以我们对 HTML标签需要有一定的认识,下面我们来一起用 html标签和 JS写一个打地鼠游戏 ,这里我们主要讲解 HTML标签的书写,只要如何和 webView适配涉及到响应式布局我们下次讲解:
1、首先我们先新建一个 html文件
2 完整 html标签并且设置编码格式为 UTF-8
3 在 body里面增加十只老鼠图片,并且增加点击事件,当点击老鼠后触发 JS函数 onclick="addScore(this);",代码如下:
<img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <img src='http://pic1.nipic.com/2008-10-16/200810169229387_2.jpg' style="max-width:90%" onclick="addScore(this);"/ alt="iOS中的webView加载HTML_html/css_WEB-ITnose" >
4 先将所有的老鼠图片放入数组中,然后开启定时器,每秒调用两次该方法,并且随机显示八个老鼠图片
//展示老鼠 function showMouse(){ //隐藏所有的老鼠 hideAll(); //控制点击次数 times++; //超过20此结束点击 if(times>20){ window.clearInterval(timer); alert("游戏结束,得分"+score+"分"); return; } //获取所有的老鼠 var imgs=document.getElementsByTagName("img"); //随机的显示八只老鼠 for(var i=0;i<8;i++){ var tem=Math.random()*10; tem= Math.round(tem); var node=imgs[tem] node.style.display=""; } } //隐藏所有老鼠 function hideAll(){ var imgs=document.getElementsByTagName("img"); for(var i=0 ;i<img s.length;i++){ var tem=imgs[i]; tem.style.display="none"; } }</pre alt="iOS中的webView加载HTML_html/css_WEB-ITnose" > <p>5 每次点击我们需要隐藏当前的图片,并且增加分数,每点击一次老鼠增加一分</p> <pre class='brush:php;toolbar:false;'> //增加分数 function addScore(cell){ cell.style.display="none"; score++; document.getElementById("label").innerHTML=score+"分数"; }
6 html加载到 webView中显示
UIWebView * web=[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 375, 667)]; NSString * path=[[NSBundle mainBundle] pathForResource:@"mouse.html" ofType:nil]; NSData * data=[NSData dataWithContentsOfFile:path]; NSString * str=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; web.scalesPageToFit=YES; [web loadHTMLString:str baseURL:nil]; [self.view addSubview:web];
