使用UIButton创建按钮，并设置一个动作（法）为将被调用。

-(void) buttonPressed:(id) sender 
{ 
    //First get the cell (We know we have the only one cell). 

    // Create an NSIndexPath to access the cell from UITableView. 
    NSIndexPath *myIndexPath = [NSIndexPath indexPathForRow:0 inSection:0]; 

    //Now We can access the cell using UITableView instance. 
    UITableViewCell *myCell = [myTabelView cellForRowAtIndexPath:myIndexPath]; 

    //Now access the instance of UITextView using viewWithTag property of UIView. 
    UITextView* myTextView = (UITextView*) [myCell viewWithTag:1]; 


    //Now you could get the text. :) 
    NSString* myTextViewText = myTextView.text ; 


}
