34 
35     [topView setBarStyle:UIBarStyleDefault];
36 
37     //定义两个flexibleSpace的button，放在toolBar上，这样完成按钮就会在最右边
38 
39     UIBarButtonItem * button1 =[[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:self action:nil];
40 
41     UIBarButtonItem * button2 = [[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:self action:nil];

45     UIBarButtonItem * doneButton = [[UIBarButtonItem alloc]initWithTitle:@"完成" style:UIBarButtonItemStyleDone target:self action:@selector(resignKeyboard)];
46 
47     //在toolBar上加上这些按钮
48 
49     NSArray * buttonsArray = [NSArray arrayWithObjects:button1,button2,doneButton,nil]; [topView setItems:buttonsArray];
50 
51     [_feedBackTextView setInputAccessoryView:topView];
