How to pass prepareForSegue: an object

Question

I have many annotations in a mapview (with rightCalloutAccessory buttons). The button will perform a segue from this mapview to a tableview

I've implemented a library with a category on UIViewController that simplifies this operation. Basically, you set the parameters you want to pass over in a NSDictionary associated to the UI item that is performing the segue. It works with manual segues too.

For example, you can do

[self performSegueWithIdentifier:@"yourIdentifier" parameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];

for a manual segue or create a button with a segue and use

[button setSegueParameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];

If destination view controller is not key-value coding compliant for a key, nothing happens. It works with key-values too (useful for unwind segues). Check it out here https://github.com/stefanomondino/SMQuickSegue
