如何從UIScrollView中獲取抽頭位置是覆蓋的UITextView

大家好......如何從UIScrollView中獲取抽頭位置是覆蓋的UITextView

我有一個TextView作爲滾動視圖的子視圖，TextView的是覆蓋所有的滾動型區域。我想要得到的位置水龍頭，滾動型，但是TextView的沒有通過它的情況下，如果我挖掘的TextView，水龍頭也滾動型檢測。我可以做到這一點？

這是我實現：

-(void)viewWillAppear:(BOOL)animated{ 
UIGestureRecognizer *tapScroll = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; 
//tapScroll.numberOfTapsRequired = 2; 
[self.scrollView addGestureRecognizer:tapScroll]; 

self.tapGesture = (UITapGestureRecognizer *)tapScroll; 
tapScroll.delegate = self; 

[tapScroll release];

}

-(void)handleTap:(UITapGestureRecognizer *)recognizer{ 
NSLog(@"handle tap"); 
location = [recognizer locationInView:self.scrollView]; 

[self.textView becomeFirstResponder]; 

NSLog(@"location tap x : %f, y : %f", location.x, location.y); 


if (location.y < self.view.frame.size.height - keyBoardBounds.size.height) { 
    NSLog(@"HEIGHT : %f", self.view.frame.size.height - keyBoardBounds.size.height); 
    [self.scrollView setContentOffset:CGPointZero animated:YES];  
}else { 
    [self.scrollView setContentOffset:CGPointMake(0, location.y/2) animated:YES]; 
}

}

我不能讓抽頭位置，因爲TextView的沒有通過它，能有人幫助我，請嗎？
