Is there any bug in Xcode's refactor?

Question

Today I want to change a name of a property,so I use refactor->rename to do this.The property is UIButton * favorites and I changed it to UIButton * collectButton; .After I finished rename I found some code interesting:

collectButton = [UIButton buttonWithType:UIButtonTypeCustom];
favorites.frame = CGRectMake(165, 10, 145, 35);
favorites.tag = 1;
[btnBgImgView addSubview:collectButton];

I am very confused and I don't know why the Xcode just rename part of the property name I appointed.Is it a bug of Xcode?Have you ever meet this bug?I am afraid that I can't use the rename function anymore.

By the way,my Xcode version is 8.0

在我重命名之前，我的代码中存在一些错误，然后我更正这些错误一切顺利。
