将一个 xib 粘贴到另一个 xib 上

Question

我想将蓝色视图粘贴到黄色视图上。

但是，无论我如何更改蓝色的自动布局，都存在冲突。

按下中间的按钮，然后显示视图。

将此行添加到您的文件 maned UIViewController+testAlert.m

containerFrame.size.width = view.frame.size.width;

就在

之后

containerFrame.size.height = view.frame.size.height;

所以你的 showAlertViewB 函数代码会像

if (show) {
    NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"AlertViewB" owner:self options:nil];
    alertViewB = (AlertViewB*)[nibViews objectAtIndex:0];
//        [alertViewB removeConstraint:alertViewB.containerHeightConstraint];
//        NSLayoutConstraint *newContainerHeightConstraint = [NSLayoutConstraint constraintWithItem:alertViewB attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeHeight multiplier:1.0 constant:view.frame.size.height];
//        [alertViewB addConstraint:newContainerHeightConstraint];
    CGRect containerFrame = alertViewB.container.frame;
    containerFrame.size.height = view.frame.size.height;
    containerFrame.size.width = view.frame.size.width;
    [alertViewB.container setFrame:containerFrame];

    [alertViewB setTranslatesAutoresizingMaskIntoConstraints:YES];
    alertViewB.delegate =self;
    [alertViewB showWithView:view];
} else {
    [alertViewB removeFromSuperview];
    alertViewB = nil;
}
