Programming iOS 8 Dive Deep into Views, View Controllers, and Frameworks

Programming iOS 8



Start building apps for iOS 8 with Apple’s Swift programming language. If you’re grounded in the basics of Xcode and the Cocoa framework, this book provides a structured explanation of all essential real-world iOS app components. Through deep exploration and copious code examples, you’ll learn how to create views, manipulate view controllers, and use iOS frameworks for adding features such as audio and video, access to user calendars and photos, and tracking the device’s location.

Example code is available on GitHub in the form of full projects that you can download, study, and run.
-Build iOS apps with Swift
-Create, arrange, draw, layer, and animate views that respond to touch
-Use view controllers to manage multiple screens in a way that’s understandable to users
-Explore UIKit interface objects, such as scroll views, table views, popovers, web views, and maps
-Work with Cocoa frameworks for sensors, location, sound, and video
-Access user libraries: music, photos, address book, and calendar
-Examine additional topics including data storage, file sharing, networking, and threading

Topics new to iOS 8 include:
-Major changes in app coordinate space and interface rotation
-Trait collections and size classes
-View margins, visual effect views, and major animation changes
-Changes to presented view controllers, popovers and split view controllers, alert and action sheet architecture
-Table view automatic variable row heights and sliding cells
-Classes for search results display, web view, video display, and audio mixing and effects

Анимация UITextField, проверка на число / UITextField not number animation

Проверка UITextField на числовой тип (float) и простая анимация если введенные данные не являются таковыми.

// Проверка введенных данных на числовую форму

- (void)textIsValidValue:(NSString *)text textField:(UITextField *)textField {

    

    BOOL result = NO;

    NSScanner *scanner = [NSScanner scannerWithString:text];

    

    if (!(result = [scanner scanFloat:NULL] && [scanner isAtEnd])) {

        

        _isWrongText = YES;

        [self animateTextFieldOnError:textField];

    

    } else { _isWrongText = NO; }

}

// Анимация поля и смена цвета текста если обнаружена ошибка

- (void)animateTextFieldOnError:(UITextField *)textField {

    

    CAKeyframeAnimation * anim = [CAKeyframeAnimation animationWithKeyPath:@"transform"];

    anim.values = @[[NSValue valueWithCATransform3D:CATransform3DMakeTranslation(-10.0f, 0.0f, 0.0f)],

                    [NSValue valueWithCATransform3D:CATransform3DMakeTranslation(10.0f, 0.0f, 0.0f)]];

    anim.autoreverses = YES;

    anim.repeatCount = 2.0f;

    anim.duration = 0.1f;

    

    [textField.layer addAnimation:anim forKey:nil];

    textField.textColor = [UIColor redColor];

Удаление / замена ненужных символов в строке

Иногда нам нужно избавиться от ненужных символов в строке, так как они могут помешать нам что либо реализовать. Например ответ от сервера с не отформатированным JSON`ом, ключи и значения которого просто разделены запятыми. По запятым мы строку разбить можем, а дальше у нас в подстроках присутствует JSON`овский мусор ( {[ключ:значение] ).
Почистить строку довольно просто (например я использую данную функцию чтобы преобразовать запятую в точку, когда пользователь вводит число с плавающей точкой с русской раскладкой):

// Смена запятой в числе на точку

- (NSString *)replacePriceCountToDotCharacter:(NSString *)string {

    

    NSCharacterSet *charactersToRemove = [NSCharacterSet characterSetWithCharactersInString:@","];

    NSString *trimmedReplacement = [[string componentsSeparatedByCharactersInSet:charactersToRemove]

                                    componentsJoinedByString:@"."];

    

    return trimmedReplacement;

}

Вместо запятой можно прописать любые символы (не разделяя никакими пробелами или запятыми) которые нужно удалить или заменить (вместо точки) на другие. Для простого удаления достаточно убрать точку и оставить строку пустой ( @"" ).
