UINavigationItem:添加按钮

CSDN移动问答

如何在navigationItem中添加新按钮?需要在右侧按钮附近:

左右按钮:

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_cancelButton];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_shareButton];

再添加一个?

    有很多方法可以实现在右侧添加一个按钮,我认为最简单的方法:

    UIView *buttonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
    
    UIButton *exampleButton1 = [UIButton buttonWithType:UIButtonTypeCustom];
    exampleButton1.frame = CGRectMake(0, 2, 30, 40);
    [exampleButton1 addTarget:self action:@selector(FirstMethod) forControlEvents:UIControlEventTouchUpInside];
    [exampleButton1 setImage:[UIImage imageNamed:@"image1.png"] forState:UIControlStateNormal];
    [buttonView addSubview:exampleButton1];
    UIButton *exampleButton2 = [UIButton buttonWithType:UIButtonTypeCustom];
    exampleButton2.frame = CGRectMake(70, 2, 30, 40);
    [exampleButton2 addTarget:self action:@selector(Second method) forControlEvents:UIControlEventTouchUpInside];
    [exampleButton2 setImage:[UIImage imageNamed:@"image2.png"] forState:UIControlStateNormal];
    
    [buttonView addSubview:exampleButton2];
    
     self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonView];
