什麼是你想要結束的確切字符串？你想從整個文本中刪除尖括號內的所有內容嗎？ – 2009-08-15 21:30:02

你是否設法解決這個問題？ – 2009-08-28 13:08:53

你希望刪除所有的你的字符串中的HTML內容？如果是這樣，你可以通過以下方式來處理它：

- (void)removeHtml:(NSString *) yourString 
{ 
    NSString *identifiedHtml = nil; 

    //Create a new scanner object using your string to parse 
    NSScanner *scanner = [NSScanner scannerWithString: yourString]; 

    while (NO == [scanner isAtEnd]) 
    { 

     // find opening html tag 
     [scanner scanUpToString: @"<" intoString:NULL] ; 

     // find closing html tag - store html tag in identifiedHtml variable 
     [scanner scanUpToString: @">" intoString: &identifiedHtml] ; 

     // use identifiedHtml variable to search and replace with a space 
     NSString yourString = 
       [yourString stringByReplacingOccurrencesOfString: 
          [ NSString stringWithFormat: @"%@>", identifiedHtml] 
          withString: @" "]; 

    } 
    //Log your html-less string 
    NSLog(@"%@", yourString); 
}

我不知道這是否會在iPhone上運行（因爲initWithHTML：documentAttributes：是AppKit的加法），但我測試過它的Cocoa程序

NSString *text = "your posted html string here";   
NSData *data = [text dataUsingEncoding: NSUnicodeStringEncoding]; 
NSAttributedString *str = 
    [[[NSAttributedString alloc] initWithHTML: data documentAttributes: nil] autorelease]; 
NSString *strippedString = [str string];
