OK. This is exactly what the autoDescribe category is meant for.
Sending it your way off line
In the debugger simply type this at a breakpoint:
po [myAwesomeObject autoDescribe]
And you’ll get something like this.
(lldb) po [indexPath autoDescribe]
2016-02-04 19:50:29.819 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] length
2016-02-04 19:50:29.819 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] row
2016-02-04 19:50:29.820 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] section
2016-02-04 19:50:29.820 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] item
2016-02-04 19:50:29.820 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] ab_item
2016-02-04 19:50:29.822 SWNDirect[76380:29705304] -[NSObject(AutoDescribe)
autoDescriptionForClassType:] [Line 90] ab_group
[NSIndexPath {length: Q = 2;
row: q = 0;
section: q = 2;
item: q = 0;
ab_item: q = 0;
ab_group: q = 2;
}]
Instead of something like this:
(lldb) po indexPath
<NSIndexPath: 0xc000000000000216> {length = 2, path = 2 - 0}
You can even use it in your log statements:
GeofenceControllerSingleton.m:1337: DLog(@" %@", [[_geofenceObjects
objectForKey:myKey] autoDescribe]);
All in all, I find it a major lack of consideration on Apple’s end to not have
something like this (and better written) in the Cocoa libs. Apple and
Objective-C tout object introspection, but Apple doesn’t hand you tools that
let you spit out your object’s guts. We shouldn’t have to write this stuff.
Really. It’s like selling a mechanic a car with no gauges.
Hope this helps.
