Question

我正在使用（轻微修改过的）第三方软件包：https://github.com/adad184/MMPopupView

我已经有了一个视图控制器，其中显示了警报并按预期工作

Iv基本上制作了一个非常相似的新控制器，并试图显示相同的警报，所以我有复制粘贴。但是我收到了错误

'NSInternalInconsistencyException', reason: 'attempting to add unsupported attribute: (null)'

工作代码：

self.alertView = MMAlertView(inputTitle: "Message", detail: "Please enter..", placeholder: "Password", handler: alertCompletion)

                self.alertView?.attachedView = self.view
                self.alertView?.attachedView.mm_dimBackgroundBlurEnabled = false;
                self.alertView?.show(0-CGFloat(self.heightForOrientation(self.interfaceOrientation, withTopBanner: false)))

不工作：

                self.dAlertView = MMAlertView(inputTitle: "Message", detail: string, placeholder: "Password", handler: alertCompletion)

                self.dAlertView?.attachedView = self.view // this crashes when on self.view??? But it works with the encryption???
                self.dAlertView?.attachedView.mm_dimBackgroundBlurEnabled = false;
                self.dAlertView?.show(0-CGFloat(self.heightForOrientation(self.interfaceOrientation, withTopBanner: false)))

我修改过的show（）：

- (void)showWithBlock:(MMPopupCompletionBlock)block
{
    if ( block )
    {
        self.showCompletionBlock = block;
    }

    if ( !self.attachedView )
    {
        self.attachedView = [MMPopupWindow sharedWindow].attachView;
    }
    [self.attachedView mm_showDimBackground];

    MMPopupBlock showAnimation = self.showAnimation;

    NSAssert(showAnimation, @"show animation must be there");

    showAnimation(self);

    [self.attachedView.mm_dimBackgroundView mas_remakeConstraints:^(MASConstraintMaker *make) {

        make.top.equalTo(self.attachedView.superview.mas_top);
        make.left.equalTo(self.attachedView.superview.mas_left);
        make.right.equalTo(self.attachedView.superview.mas_right);

        make.bottom.equalTo(self.attachedView.superview.mas_bottom).with.offset(self.keyboardHeight);
    }];

    if ( self.withKeyboard )
    {
        [self showKeyboard];
    }
}

追溯显示触发它的砌体视图约束：

*** Assertion failure in -[MASViewConstraint setSecondViewAttribute:], /Users/Nic/Sync/iPGP/Pods/Masonry/Masonry/MASViewConstraint.m:130

我非常有信心它与我的主视图（self.view）有关，就像我在主视图中的编辑器中添加子视图一样，例如.. self.testview 我没有收到错误消息..

我无法理解为什么会发生这种情况，我已经检查过并且参考插座设置完全相同。静脉注视的一切都是一样的

我在添加更多子视图时遇到了一些其他问题，并且再次考虑代码是一样的我假设主要的self.view一定有问题吗？

'NSInternalInconsistencyException'，原因：'尝试添加不支持的属性：（null）'
