IOS xib View width and height cannot be changed, and iosxibview height cannot
IOS-xib (Interface Builder, view)-can't change view size (view cannot change the size)

I am trying to write a demo in swift today. I have encountered this problem. Let's share it.

When we customize the cell of tableview and collectionview, and sometimes we want to customize the window xib, but after the xib is created, its height and width cannot be modified.

Then the problem arises. How can we modify the custom xib width and height:

Create xib in the project,

Method:

Size: inferred (inferred) in Simulated metric by default, the height and width of the view cannot be changed;

Change to Size: Freeform. Now we can modify the xib view width and height.

I did not really care about this problem before. Today I know it! Hope to continue learning
