In every method two very important variables can be found. One is already known by many iOS dev, and it is ‘self’. The other one is ‘_cmd’. This last one is the selector of the current method. This variable can useful for logging purposes. In the Silver Sparrow log framework, it is used inside a macro in order to add important information to a log entry.
For example:
NSLog(@"{ERROR} [%@ %@] %@", NSStringFromClass([self class]), NSStringFromSelector(_cmd), message);
In this line, the class name and the method name are added to NSLog.
You can download and use the log library, which is available at SSLoger on GitHub
