    NSLog(@"single tap"); 

CGPoint touchPoint = [gestureRecognizer locationInView:wbCont]; 

//NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).toString()", touchPoint.x, touchPoint.y]; 

    NSString *js = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).innerHTML", touchPoint.x, touchPoint.y]; 

NSString * tagName = [wbCont stringByEvaluatingJavaScriptFromString:js]; 

NSLog(@"Selected Name: %@",tagName); 

} 

Answer 1

我得到的答案從stringByReplacingOccurrencesOfString:功能。我在下面的代碼中使用。它工作正常。

tagName=[tagName stringByReplacingOccurrencesOfString:@" " withString:@""];
