Answer 1

您需要创建一个自定义按钮并使用initWithCustomView初始化您的UIBarButtonItem。

如果使用自定义图片，则按照自己的意愿创建UIButton，然后：

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:yourUIButton];

Answer 2

制作标准的UIBarButtonItem受到限制。但你可以使用你选择的任何UIView来启动它，例如标准的UIButton，您可以根据自己的喜好进行着色。

UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame = CGRectMake(0, 0, 30, 20); // change as you like being constrained with navigation bar hieght
[myButton setTitle:@"My Button" forState:UIControlStateNormal];
[myButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
[myButton setImage:[UIImage imageNamed:@"Image for my button.png"] forState:UIControlStateNormal]; // <-- you can provide image instaed of title if you like
[myButton setBackgroundImage:[UIImage imageNamed:@"Background image for my button.png"] forState:UIControlStateNormal];
[myButton addTarget:self action:@selector(myAction) forControlEvents:UIControlEventTouchUpInside]; // <-- don't forget configure this!!! 
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myButton];
