目标c是否具有带标签功能？ [英] Does objective c have a strip tags function?

问题描述

我正在寻找一个目标C函数（自定义或内置），用于从字符串中去除html标签，类似于PHP的版本，可以在这里找到：

http://php.net/manual/en/function.strip-tags .php

任何帮助将不胜感激！

解决方案

<这只是消除了< 和> 字符以及它们之间的所有内容，我认为这是足够的： p>

   - （NSString *）stripTags：（NSString *）str 
 {
 NSMutableString * ms = [NSMutableString stringWithCapacity ：[str length]]; 
 
 NSScanner * scanner = [NSScanner scannerWithString：str]; 
 [scanner setCharactersToBeSkipped：nil]; 
 NSString * s = nil; 
 while（！[scanner isAtEnd]）
 {
 [scanner scanUpToString：@< intoString：安培; S]; 
 if（s！= nil）
 [ms appendString：s]; 
 [scanner scanUpToString：@> intoString：NULL]; 
 if（！[scanner isAtEnd]）
 [scanner setScanLocation：[scanner scanLocation] +1]; 
 s = nil; 
} 
 
 return ms; 
} 
  

I am looking for an objective C function (custom or built-in) that strips html tags from a string, similar to PHP's version that can be found here:

http://php.net/manual/en/function.strip-tags.php

Any help would be appreciated!

解决方案

This just removes < and > characters and everything between them, which I suppose is sufficient:

- (NSString *) stripTags:(NSString *)str
{
    NSMutableString *ms = [NSMutableString stringWithCapacity:[str length]];

    NSScanner *scanner = [NSScanner scannerWithString:str];
    [scanner setCharactersToBeSkipped:nil];
    NSString *s = nil;
    while (![scanner isAtEnd])
    {
        [scanner scanUpToString:@"<" intoString:&s];
        if (s != nil)
            [ms appendString:s];
        [scanner scanUpToString:@">" intoString:NULL];
        if (![scanner isAtEnd])
            [scanner setScanLocation:[scanner scanLocation]+1];
        s = nil;
    }

    return ms;
}
