Question

我在xml中声明了一个故事板，

当我将xml cpoy /粘贴到实际的sotryboard中时，我的一些视图将被移动，因此元素的x，y宽度和高度将会不同。

该设计旨在符合iphone6标准。处理自动布局。但是，看起来像这样

<view contentMode="scaleAspectFit" fixedFrame="YES" insetsLayoutMarginsFromSafeArea="NO" translatesAutoresizingMaskIntoConstraints="NO" id="cz19r018cejc92w3fw">
<rect key="frame" x="0" y="600" width="375" height="66"/>
<autoresizingMask key="autoresizingMask" flexibleMinX="YES" widthSizable="YES" flexibleMaxX="YES" flexibleMinY="YES" heightSizable="YES" flexibleMaxY="YES"/>

将更改为

<view contentMode="scaleToFill" fixedFrame="YES" insetsLayoutMarginsFromSafeArea="NO" translatesAutoresizingMaskIntoConstraints="NO" id="cz19r018cejc92w3fw">
<rect key="frame" x="0.0" y="596" width="375" height="65"/>
<autoresizingMask key="autoresizingMask" flexibleMinX="YES" widthSizable="YES" flexibleMaxX="YES" flexibleMinY="YES" heightSizable="YES" flexibleMaxY="YES"/>

注意Y从600变为596，高度从66变为65.

知道如何避免这种行为吗？

编辑：

我正在使用Xcode 9.2，故事板被设置为View as: iPhone8 我正在生成完整的故事板本身，而不仅仅是一个视图。这是一个产生行为的故事板。

完整xml中的第21行是错误的：

updateChildren()

它应该是：

FirebaseUser user=FirebaseAuth.getInstance().getCurrentUser();
String useruid=user.getUid();
DatabaseReference ref=FirebaseDatabase.getInstance().getReference().child("Accounts").child("user").child(useruid);
Map<String, Object> updates = new HashMap<String,Object>();

updates.put("date", newdate);
updates.put("email", newemail);
updates.put("name", newname);
updates.put("type", newtype);

ref.updateChildren(updates);

<rect key="frame" x="0.0" y="0.0" width="375" height="672"/>代替<rect key="frame" x="0.0" y="0.0" width="375" height="667"/>
