ios - One protocol, used by many classes -


I understand how a class can be tailored to several protocols, but where and how do I define a protocol Which can be called in many sections, i.e. 

  _delegate.doStuff

can appear in many sections.

in encode,

file-> new file-> Objective-Protocol 

  @protocol myProtocolName - (zero) doStuff; @end

Then in the sections you want to implement this protocol 

  ... #import "myProtocol.h" @ interface aclass & lt; MyProtocolName & gt; ...

You can add it to any class.

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file.
