CRChecker

Objective-C Circular Reference Checker

How can we find out circular reference problem?

It's not a difficult issue.

We just swizzling Objective-C init and dealloc method, every object will execute these method at live cycle start and end.

If your instanced object has circular reference problem. These object may not be dealloc.

So, we set a counter, just make all classes init +1, dealloc -1.

You see, the dashBoard data source came here.

[CRChecker addCustomClassPrefix:@"Demo"];

Only Demo Prefix Classes will be record.
