的iOS RangeOfString NSRegularExpressionSearch

Question

我有一個小問題，我使用一個代碼片段從iOS的字符串中刪除的html代碼：

while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound) 
     s = [s stringByReplacingCharactersInRange:r withString:@""]; 

，現在我需要刪除一些塊，等等。爲什麼這段代碼不工作：

while ((r = [s rangeOfString:@"<style[^>]+style>" options:NSRegularExpressionSearch]).location != NSNotFound) 
    s = [s stringByReplacingCharactersInRange:r withString:@""]; 

感謝您的幫助！

試試這個：

while ((r = [s rangeOfString:@"<style[^>]+>[^>]+</style>" options:NSRegularExpressionSearch]).location != NSNotFound) { 
    s = [s stringByReplacingCharactersInRange:r withString:@""]; 

}
