Swizzlean

Swizzlean is a quick and “lean” way to swizzle methods for your Objective-C development needs.

How To

Create an instance of swizzlean passing in the class of the methods you want to swizzle.

Call swizzleInstanceMethod:withReplacementImplementation: for an instance method passing in the selector of the method to be swizzled with the replacement implementation. When passing in the replacement implementation block, the first parameter is always id _self (pointer to the ‘Class’ being swizzled), and the followed by any other parameters for the method being swizzled.

Call swizzleClassMethod:withReplacementImplementation: for a class method passing in the selector of the method to be swizzled with the replacement implementation.

You can check the current instance/class method that is swizzled by using the currentInstanceMethodSwizzled and currentClassMethodSwizzled methods.

The status of the swizzled methods can be seen by calling isInstanceMethodSwizzled and isClassMethodSwizzled.

Use reset methods to unswizzle the instance/class methods that are currently being swizzled.

Methods are automatically reset when the Swizzlean object is deallocated. If you would like to keep the methods swizzled after dealloc is called, set the property resetWhenDeallocated = NO.
