ScrollView在[textview resignFirstResponder]之后停止滚动

解释这个问题并不是很容易，但我会尝试：我有一个视图witch scrollview，里面有很多textview和textfield。ScrollView在[textview resignFirstResponder]之后停止滚动

我想，当有人didbegin编辑一个字段（或TextView的），以向上和向下滚动，所以我有：

- (void)keyboardDidShow:(NSNotification*)aNotification{ 
NSDictionary* info = [aNotification userInfo]; 
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size; 

UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0); 
o_scroolView.contentInset = contentInsets; 
o_scroolView.scrollIndicatorInsets = contentInsets; 

// If active text field is hidden by keyboard, scroll it so it's visible 
// Your application might not need or want this behavior. 
CGRect aRect = self.view.frame; 
aRect.size.height -= kbSize.height; 
if (!CGRectContainsPoint(aRect, activefield.frame.origin)) { 
    CGPoint scrollPoint = CGPointMake(0.0, activefield.frame.origin.y-kbSize.height); 
    [o_scroolView setContentOffset:scrollPoint animated:YES]; 
} 
} 
- (void)keyboardDidHide:(NSNotification*)aNotification 
{ 
UIEdgeInsets contentInsets = UIEdgeInsetsZero; 
o_scroolView.contentInset = contentInsets; 
o_scroolView.scrollIndicatorInsets = contentInsets; 
activefield=NULL; 
}

像苹果的文档说。 Offcourse activefield是一个UIView *通过

-(void)textFieldDidBeginEditing:(UITextField *)textField { 
NSLog(@"textFieldDidBeginEditing"); 
activefield=textField; 

} 

- (void)textViewDidBeginEditing:(UITextView *)textView{ 
NSLog(@"textViewDidBeginEditing"); 
activefield=textView; 
}

确定分配的一切，除了正常工作时

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
replacementText:(NSString *)text 
{ 

// Any new character added is passed in as the "text" parameter 
if ([text isEqualToString:@"\n"]) { 
    // Be sure to test for equality using the "isEqualToString" message 

    // [self EnablePrice:TRUE]; 
    [textView resignFirstResponder]; 
    // Return FALSE so that the final '\n' character doesn't get added 
    return FALSE; 
} 
// For any other character return TRUE so that the text gets added to the view 
return TRUE; 
}

的辞职滚动视图（_scrollview）后停止，当我我的手指移动上下移动。

Thx in advice。
