//定义UIToolBar m_pToolBar= [[UIToolbar alloc]initWithFrame:CGRectMake(0.0,self.view.frame.size.height- m_pActionButton.frame.size.height- 44.0,self.view.frame.size.width,44.0)]; [m_pToolBar setBarStyle:UIBarStyleBlackOpaque]; m_pToolBar.autoresizingMask=UIViewAutoresizingFlexibleTopMargin; //向uitoolbar添加控件   m_pTextField=[[UITextFieldalloc]initWithFrame:CGRectMake(12.0,7.0,264.0,31.0)]; m_pTextField.delegate= self; [m_pTextField setBorderStyle:UITextBorderStyleRoundedRect]; [m_pTextField setFont:[UIFont fontWithName:@"Helvetica" size:16.0]]; m_pButtonAdd= [UIButton buttonWithType:UIButtonTypeCustom]; [m_pButtonAdd setFrame:CGRectMake(286.0,8.0,29.0,29.0)]; [m_pButtonAdd addTarget:selfaction:@selector(addOpinion) forControlEvents:UIControlEventTouchUpInside]; [m_pButtonAdd setImage:[UIImage imageNamed:@"button_plus"] forState:UIControlStateNormal];   UIBarButtonItem *mBarButtonItemTextField =[[UIBarButtonItemalloc] initWithCustomView:m_pTextField]; UIBarButtonItem *mBarButtonItemButtonAdd =[[UIBarButtonItemalloc] initWithCustomView:m_pButtonAdd]; [m_pToolBarsetItems:[NSArrayarrayWithObjects:mBarButtonItemTextField,mBarButtonItemButtonAdd,nil]]; [mBarButtonItemTextFieldrelease]; [mBarButtonItemButtonAddrelease];
