用谷歌API显示地图，然后有一些HTML方向字符串，包含了HTML标签。
现在我想在普通文本中显示这些字符，不知道应该怎么实现？字符串如下：
Head <b>southwest</b> toward <b>GH Rd</b>
Exit the roundabout onto <b>GH Rd</b><div style="font-size:0.9em">Go through 1 roundabout</div>
At the roundabout, take the <b>1st</b> exit onto <b>Road Number 2</b><div style="font-size:0.9em">Pass by myonlinesearch.blogspot.com (on the left in 600 m)</div>
At the roundabout, take the <b>3rd</b> exit onto <b>CH Rd</b>
At <b>Indroda Cir</b>, take the <b>2nd</b> exit onto <b>Gandhinagar Ahmedabad Rd/SH 71</b><div style="font-size:0.9em">Continue to follow Gandhinagar Ahmedabad Rd</div><div style="font-size:0.9em">Go through 1 roundabout</div>
At the roundabout, take the <b>1st</b> exit onto <b>Sardar Patel Ring Rd</b>
At <b>Ranasan Cir</b>, take the <b>3rd</b> exit onto <b>NH 8</b><div style="font-size:0.9em">Pass by Galaxy Restaurant (on the left in 4.3 km)</div>
Turn <b>left</b> onto <b>Galaxy Rd</b><div style="font-size:0.9em">Pass by Shiv Shakti Food Fort (on the left)</div>
Turn <b>left</b> onto <b>NH 59</b>
Turn <b>right</b><div style="font-size:0.9em">Go through 1 roundabout</div>
Turn <b>right</b>
Turn <b>left</b><div style="font-size:0.9em">Destination will be on the right</div>
可以用RegularExpression/Predicates移除< & >内所有的内容
不过如果文本也包含 <> 也会被移除
NSRange range;
NSString *string;
while ((range = [string rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound){
string=[string stringByReplacingCharactersInRange:range withString:@""];
}
NSLog(@"Un block string : %@",string);
你需要转义<、>、 "和'。用正则替换就行了。
如果你只是直接显示的话，直接用UIWebView就可以了 。
[self.webView loadHTMLString:htmlString baseURL:nil];
你可以参考官方例子TransWeb。将含有标签的xml文件显示出来。
