Except a genre, games have the form. It as art — is poems and even novels, and there are poems. Pushkin, for example, occasionally ten verses in a week in Appstore spread. And we plow sometimes not worse than the genius. Ouch yes we with Pushkin, ouch yes sons of a bitch!

Magic of IBDesignable or we expand functionality of Interface Builder in Xcode

1 year, 4 months ago


Interface Builder in Xcode since some time saves to me a lot of time in work on a standard layaut of elements of the interface and sometimes helps with a problem of prototyping. From version 6 in Xcode added a feature for a render of the custom work line racks marked with the IBDesignable attribute and also display in a bilder of the fields of a class marked with the IBInspectable attribute.

From the Xcode 7 version this feature became more or less possible to use therefore I wanted to check its opportunities.

Objective-C questions on the middle/senior level

1 year, 4 months ago
What the developer on the middle/senior level has to know objc?
Unfortunately, there is no accurate line on vertical development. Paradox, but that know what to study, it is necessary to know what you do not know.
I tried to remember the most interesting questions which to me were asked most on different interviews, and also expanded them with a set of questions (the same level) from myself.
There are no general questions it seems: IoC, design patterns, S.O.L.I.D., etc.

ATTENTION!!!
In addition to vertical development it is important also horizontal

ATTENTION!!! (2)
Do not write answers to questions to comments, it gives the chance to people independently to understand.
However, if you have interesting questions on a subject, I with pleasure will add them to the list.

Of course, it will not replace real-life communication, however will allow to be prepared for interviews not bad.
