将HTML内容写入NSString并显示在iPhone上 [英] write html content to NSString and display on iphone

问题描述

我有一个webveiw，可以显示较小的html值，但有问题

i have a webveiw where i can show small html value but i have a issue

如果是这样

NSString *HTMLData =@"<h3><span style=font-family:Helvetica-Bold > <strong> Information</strong> </span></h3>";


    HTMLData= [HTMLData stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];


    [web loadHTMLString:HTMLData baseURL:nil];

然后可以正常工作

但是如果我的NSString有换行符，可以说

but if my NSString has a break line lets say

    NSString *HTMLData =@"<h3><span style=font-family:Helvetica-Bold >
 <strong> Information</strong>
 </span></h3>";

然后我遇到错误了如何避免此错误??? 我的错误缺少终止符

then i am getting error how to avoid this error??? my error is missing terminator charcter

推荐答案

要将多行中的长NSString分隔开，需要在每行的末尾加上双引号:

To break long NSStrings across multiple lines, you need to put double quotes at the end and beginning of each line:

NSString *HTMLData =@"<h3><span style=font-family:Helvetica-Bold >"
    "<strong> Information</strong>"
    "</span></h3>";

修改:
NSMutableString的示例:

An example with NSMutableString:

NSMutableString *HTMLData = [[NSMutableString alloc] initWithCapacity:100];
[HTMLData appendString:@"<h3><span style=font-family:Helvetica-Bold >"];
[HTMLData appendString:@"<strong> Information</strong>"];
[HTMLData appendString:@"</span></h3>"];
//more appends...

//do something with HTMLData here

[HTMLData release];

initWithCapacity只是告诉您最初要分配多少个字符(这不是限制).

The initWithCapacity just tells how many characters to allocate space for initially (it's not a limit).

NSMutableString也具有appendFormat:方法，其作用类似于stringWithFormat:.

NSMutableString also has the appendFormat: method which works like stringWithFormat:.
