iOS 自定义Navigation

 本人刚学习iOS个人笔记不喜请勿喷

 //设置navigationController的背景颜色

  [self.navigationController.navigationBarsetBarTintColor:[UIColororangeColor]];

  //自定义一个view为title（image）的载体

    UIImageView *imageView = [[UIImageViewalloc] initWithImage:[UIImageimageNamed:@"吉"]];

  //将自定义title（image）的载体添加到navigationItem上

    self.navigationItem.titleView = imageView;

    //设置文字

//    UILabel *textView1=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height)];

//    textView1.backgroundColor=[UIColor blackColor];

//    textView1.text = @"首页";

//    textView1.textColor = [UIColor whiteColor];

//    [self.navigationItem setTitleView:textView1];

    

//  自定义一个button 

    UIButton *LeftBtn = [[UIButtonalloc]init];

    LeftBtn.frame  = CGRectMake(0,0, self.navigationController.navigationBar.frame.size.height,self.navigationController.navigationBar.frame.size.height);

    LeftBtn.backgroundColor = [UIColor blueColor];

//  将自定义的button添加到系统的UIBarButtonItem上

    UIBarButtonItem *LeftBarBtn = [[UIBarButtonItemalloc]initWithCustomView:LeftBtn];

//将系统的UIBarButtonItem 添加到navigationItem的左侧

    self.navigationItem.leftBarButtonItem = LeftBarBtn;

    UIButton *RightBtn = [[UIButtonalloc]init];

    RightBtn.frame  = CGRectMake(0,0, self.navigationController.navigationBar.frame.size.height,self.navigationController.navigationBar.frame.size.height);

    RightBtn.backgroundColor = [UIColor blueColor];

    

    UIBarButtonItem *RightBarBtn = [[UIBarButtonItemalloc]initWithCustomView:RightBtn];

//将系统的UIBarButtonItem 添加到navigationItem的右侧

    self.navigationItem.rightBarButtonItem = RightBarBtn;
