A hotfix library based on flex/yacc. You can call any Objective-C class and method using DynamicOC. DynamicOC is functionally similar to JSPath, but it only needs to write native OC syntax to implement hotfix.
- dynamically execute Objective-C code
- dynamically execute C function and block
- dynamically add property
- dynamically replace method
- dynamically add method
- Completed and detailed unit test
- powerful OC syntax parser based on flex/yacc
- support CGRect/CGSize/CGPoint/NSRange/UIEdgeInsets/CGAffineTransform C-struct ...
