Really quick question (I could test it myself but not on a computer with Xcode):
真的很快问题（我可以自己测试但不能在带Xcode的计算机上测试）：
If ARC sets a weak property to nil, will the property's setter run with the parameter being nil, or is the property setter bypassed in this case?
如果ARC将弱属性设置为nil，属性的setter是否会以参数nil运行，或者在这种情况下是否绕过属性setter？

No. ARC doesn't set properties to nil. It will set the backing ivar to nil, but that doesn't run your setter.
否.ARC不会将属性设置为nil。它会将支持ivar设置为nil，但这不会运行你的setter。
