ios - iOS 11 UIBarButtonItem ImageView大小错误

Question

您好，今天早上在iOS 11上，我发现了许多iOS 10所没有的错误。我纠正了除两个错误以外的大多数错误，此处的配置文件图像位于右上方

代码按钮:

UIImageView* v = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 35, 35)];
    v.image = img;
    v.layer.masksToBounds = YES;
    v.layer.cornerRadius = 17.5;

    UIBarButtonItem* rightBtn = [[UIBarButtonItem alloc] initWithCustomView:v];
    self.navigationItem.rightBarButtonItem = rightBtn;

///// iOS 10 /////



///// iOS 11 /////

Answer 1

在iOS 11中，您必须需要我们自动布局而不是框架

像下面

    myButton.widthAnchor.constraint(equalToConstant: customViewButton.width).isActive = true
    myButton.heightAnchor.constraint(equalToConstant: customViewButton.height).isActive = true
