推荐答案

您可以将图像用作按钮图像

your can use image as button image as

UIImage *buttonImage = [UIImage imageNamed:@"image.png"];

//create the button and assign the image
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];


//create a UIBarButtonItem with the button as a custom view
//UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

[button addTarget:self action:@selector(clickActionItem:) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button ];




self.navigationItem.rightBarButtonItem = rightBarButtonItem;
