ITNDescription

A category on NSObject, that automatically generates debugging description.

An example at the beginning. Printing instance of MYSomething class that has no special code for description:

po [something itn_longDescription]

<MYSomething: 0x10923d4b0> {
    _UUID = <__NSConcreteUUID 0x109235250> D1972A0F-FADC-48A9-907E-5EF954FB51AE,
    _owner = <MYSomeone: 0x109205fc0> {
        _UUID = <__NSConcreteUUID 0x109404420> D5B9F54D-A5E1-4880-A93F-44A36ABF1CBF,
        _displayName = “Someone”,
    },
    _displayName = “Something”,
    _passcode = 2376,
    _isActive = No,
    _thatThing = <MYThing: 0x10923da50> {
        _something = <MYSomething: 0x10923d4b0>,
        _member = <MYSomeone: 0x109205fc0>,
        _isThere = Yes,
        _isBusy = No,
    },
    _moreThings = 3 objects (
        <MYThing: 0x1092eda56>,
        <MYThing: 0x60ef3dcd0>,
        <MYThing: 0x90925da53>,
    ),
    _manager = <MYManager: 0x10923def0> {
        _something = <MYSomething: 0x10923d4b0>,
        _competency = nil,
    },
}

Prints all properties that have ivars. Optionally recursively and with whitespace padding.
If the receiver overrides -description or -debugDescription, that implementation is called. This is important for existing framework classes, that don't have ivars.
Custom description for NSString, boolean NSNumbers, NSArray, NSDictionary (and more in future, maybe). Provides easily readable descriptions for those types.

Methods

itn_shortDescription – Prints short one-line description, usually in format <MYClass: 0x90925da53>.
itn_longDescription – Prints longer description of the receiver up to 2nd depth level as seen in the example.
itn_descriptionWithDepth: – Prints description recursively with custom depth level. Zero depth prints short description.
itn_descriptionWithIndentation:depth: – This is the core method to do recursion. Recursively decrements depth by one, until it reaches zero.
