iphone 自定义导航栏按钮

通常使用的NavigationItem中有backBarButtonItem/leftBarButtonItem/rightBarButtonItem三个按键,其中backBarButtonItem为只读,不能修改,其他两个都可以自由修改.不但可以防止button,还可以用自定义的view来填充,比方说想在导航栏右侧防止两个按钮,

如图所示

代码如下：

UIView *rightBarView = [[UIView alloc]initWithFrame:CGRectMake(618,0, 150, 44)];

UIButton *editBtn = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

[editBtn setFrame:CGRectMake(10, 10, 50, 25)];

[editBtn addTarget:self action:@selector(editAction:)forControlEvents:UIControlEventTouchUpInside];

[editBtn setTitle:@"编辑" forState:UIControlStateNormal]; [editBtnsetTag:11];

[rightBarView addSubview:editBtn];

 

UIButton *submitBtn = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

[submitBtn setFrame:CGRectMake(80, 10, 70, 25)];

[submitBtn addTarget:self action:@selector(submitAction:)forControlEvents:UIControlEventTouchUpInside];

[submitBtn setTitle:@"提交订单" forState:UIControlStateNormal];[submitBtn setTag:12];

[rightBarView addSubview:submitBtn];

UIBarButtonItem *rightBtn = [[UIBarButtonItemalloc]initWithCustomView:rightBarView];

self.navigationItem.rightBarButtonItem = rightBtn;
