UITextField анимация / UITextField animation
Каждому из нас очень часто приходится (например в окне ввода логина / пароля) сдвигать поля ввода чтобы клавиатура не перекрывала их и пользователь видел то что он вводит. Для сдвига с места обычно достаточно простой анимации, но мы как всегда - сделаем это красиво ;)
Представим что у нас на вьюхе есть три UITextField. Создадим массив и добавим эти UITextField в него. UITextField уже размещены в нужных нам местах. Теперь при тапе на один из них (любой) появится клавиатура которая естественно перекроет UITextField (во многих ситуациях именно так и есть, особенно на iPad при Landscape ориентации устройства. Сдвигаем:
CGAffineTransform textFieldTranslationTransform; textFieldTranslationTransform = CGAffineTransformMakeTranslation(0, -165);
Важно помнить, что место с которого будет передвигаться UITextField - центр равен 0. Когда элементы станут на новое место, центр каждого элемента станет опять 0. Чтобы опять поставить на место, вместо "-165" ставим "165". Т.е. цифры говорят о том, что мы передвинули не В координату, а НА определенное количество пунктов.
[_textFieldsArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { UITextField *tField = (UITextField *)obj; [UIView animateWithDuration:0.9 delay:0.05 * (double)idx usingSpringWithDamping:0.5 initialSpringVelocity:0 options:UIViewAnimationOptionCurveLinear animations:^{ tField.center = CGPointApplyAffineTransform(tField.center, textFieldTranslationTransform); } completion:nil]; }];

Penn J., Smith J. Build iOS Games with Sprite Kit: Unleash Your Imagination in Two Dimensions
Take your game ideas from paper to pixels using Sprite Kit, Apple's 2D game development engine. Build two exciting games using Sprite Kit and learn real-world, workshop-tested insights about game design, including cognitive complexity, paper prototyping, and levels of fun.
You'll learn how to implement sophisticated game features such as obstacles and weapons, power-ups and variable difficulty, physics, sound, special effects, and both single- and two-finger control. In no time, you'll be building your own thrilling iOS games.
Deitel P., Deitel H. Swift for Programmers
The Swift™ programming language was arguably the most significant announcement at Apple’s 2014 Worldwide Developers Conference. Although apps can still be developed in Objective-C®, Apple says that Swift is its applications programming and systems programming language of the future.
Swift is a contemporary language with simpler syntax than Objective-C. Because Swift is new, its designers were able to include popular programming language features from languages such as Objective-C, Java™, C#, Ruby, Python® and many others. These features include automatic reference counting (ARC), type inference, optionals, String interpolation, tuples, closures (lambdas), extensions, generics, operator overloading, functions with multiple return values, switch statement enhancements and more. We’ve been able to develop apps more quickly in Swift than with Objective-C and the code is shorter, clearer and runs faster on today’s multi-core architectures.
Swift also eliminates the possibility of many errors common in other languages, making your code more robust and secure. Some of these error-prevention features include no implicit conversions, ARC, no pointers, required braces around every control statement’s body, assignment operators that do not return values, requiring initialization of all variables and constants before they’re used, array bounds checking, automatic checking for overflow of integer calculations, and more. You can combine Swift and Objective-C in the same app to enhance existing Objective-C apps without having to rewrite all the code. Your apps will easily be able to interact with the Cocoa®/Cocoa Touch® frameworks, which are largely written in Objective-C.

You can also use the new Xcode playgrounds with Swift. A playground is an Xcode window in which you can enter Swift code that compiles and executes as you type it. This allows you to see and hear your code’s results as you write it, quickly find and fix errors, and conveniently experiment with features of Swift and the Cocoa/Cocoa Touch frameworks.

Classes, Objects, Methods, Properties
Initializers, Deinitializers, Bridging
Tuples, Array and Dictionary Collections
Structures, Enumerations, Closures, ARC
