~~Title: Objective-C Style~~

Alle unsere Objective-C Klassen verwenden einen einheitlichen Style.

==== Protokolle ====

Für Protokolle verwenden wir folgenden Style:

<file objc ProtocolTemplate>

/*!
  @protocol Foo
  @abstract Protocol implemented by Bar.
  @discussion That's what they do. 
*/
@protocol Foo

#pragma mark -
#pragma mark Required

/*!
  @method requiredMethod:
  @abstract Validates the specified item.
  @param pItem The item to be validated.
*/
- (void)requiredMethod:(id) pItem;

/*!
  @method anotherRequiredMethod:
  @abstract Applies validation rules.
*/
- (void)anotherRequiredMethod;

#pragma mark -
#pragma mark Optional

@optional

/*!
  @method anOptionalMethod:
  @abstract Checks optional things.
*/
- (void)anOptionalMethod;

/*!
  @method anotherOptionalMethod:
  @abstract Checks another optional things.
*/
- (void)anotherOptionalMethod;

@end
</file>

Folgende Regeln werden durch diese Vorlage definiert:

  * Zuerst werden die erforderlichen Methoden definiert
  * danach alle optionalen Methoden
  * Gruppierung mit #pragma mark ...
  * Im Header erstellen wir bei wichtigen Änderungen einen Hinweis mit Zeitstempel und Autor
  * Dokumentation für die Protokoll Deklaration und alle Methoden

==== Interfaces ====

Für Interfaces (.h files) verwenden wir folgenden Style:

<file objc InterfaceTemplate>

#import "Bar.h"

/*!
  @class Foo
  @abstract Foo provides a UI element.
  @discussion A Foo object is a simple view that can do two things:  Jump, Run. 
*/
@interface Foo : Bar
{
    #pragma mark -
    #pragma mark Instance variable declarations
  
    @private 

    /*! @var value the value of foo. */
    float value;
}

#pragma mark -
#pragma mark Property declarations

/*! @property value the value property. */
@property float value;

#pragma mark -
#pragma mark Initialization

/*!
  @method initWithString:
  @abstract Creates a new foo with string representation of width and height.
  @param pString the width and height
  @result a new Foo instance.
*/
- (id)initWithString:(NSString *)pString;

#pragma mark -
#pragma mark Method declarations

/*!
  @method concatWidth:height:
  @abstract Concatenates the width and height.
  @param pWidth the width.
  @param pHeight the height.
  @result the string representation.
*/
+ (NSString *)concatWidth:(float)pWidth height:(float):pHeight;

/*!
  @method setWidth:height:
  @abstract Sets the foo width and height.
  @param pWidth the width.
  @param pHeight the height.
*/
- (void)setWidth:(float)pWidth height:(float)pHeight;

@end
</file>

Folgende Regeln werden durch diese Vorlage definiert:

  * Gruppierung mit #pragma mark ...
  * Im Header erstellen wir bei wichtigen Änderungen einen Hinweis mit Zeitstempel und Autor
  * Dokumentation für die Klassen Deklaration, ALLE Methoden, Properties und Variablen

==== Klassen ====

Für Klassen (.m files) verwenden wir folgenden Style:

<file objc ClassTemplate>
/*
 * Copyright 2018 SIB Visions GmbH
 * 
 * Licensed under the Apache License, Version 2.0 (the "License"); you may not
 * use this file except in compliance with the License. You may obtain a copy of

#import "Foo.h";


@implementation Foo

#pragma mark -
#pragma mark Properties

@synthesize value;

#pragma mark -
#pragma mark Initialization

- (id)initWithString:(NSString *)pString
{
    ...
}

#pragma mark -
#pragma mark Method declarations

+ (NSString *)concatWidth:(float)pWidth height:(float):pHeight
{
    ...
}

- (void)setWidth:(float)pWidth height:(float)pHeight
{
    ...
}

@end
</file>

Folgende Regeln werden durch diese Vorlage definiert:

  * Gruppierung mit #pragma mark ...
  * Im Header erstellen wir bei wichtigen Änderungen einen Hinweis mit Zeitstempel und Autor

==== Unit Tests ====

Als Testing Framework kommt OCUnit zum Einsatz.

Für Unit Tests verwenden wir folgenden Style:

<file objc TestTemplate>
/*
 * Copyright 2018 SIB Visions GmbH
 * 
 * Licensed under the Apache License, Version 2.0 (the "License"); you may not
 * use this file except in compliance with the License. You may obtain a copy of

 * 
 * Unless required by applicable law or agreed to in writing, software
 * distributed under the License is distributed on an "AS IS" BASIS, WITHOUT
 * WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the
 * License for the specific language governing permissions and limitations under
 * the License.
 *
 *
 * History
 * 
 * dd.MM.yyyy - [XX] - creation
 */

#import "Foo.h"


@implementation FooTest

#pragma mark -
#pragma mark Internal methods

#pragma mark -
#pragma mark Test methods

/*!
  @abstract Tests the init method.
*/
- (void)testInit
{
    ...
}

@end
</file>

Folgende Regeln werden durch diese Vorlage definiert:

  * Gruppierung mit #pragma mark ...
  * Jede Test Klasse endet mit "Test"
  * Jede Test Methode beginnt mit "test"
  * Im Header erstellen wir bei wichtigen Änderungen einen Hinweis mit Zeitstempel und Autor
  * Dokumentation für die Klassen Deklaration und alle Test Methoden
