Today’s post is actually going to be a really short one. There isn’t too much to really show, however its something that I had to look up a few times when I started working with Objective-C, so I figured its a good topic to cover anyways.
C#:public enum Orientation{ Vertical = 0, Horizontal} Objective-C:typedef enum{ OrientationVertical = 0, OrientationHorizontal}Orientation;As in C#, it is optional to set the integer value of an enumeration object.
You should include your enum declaration in a header (.h) file as opposed to the implementation(.m) file.
Now lets take a look at consuming the enumeration we just created.
C#:public Orientation LabelOrientation{get;set;}; this.LabelOrientation = Orientation.Horizontal; Objective-C:@property(nonatomic, assign) Orientation labelOrientation; self.labelOrientation = OrientationHorizontal;Note the differences. When you access an enum value in C#, you use dot notation to obtain a value. Where as in Objective-C you use the value straight up. Which is why its good practice to include the enumeration's name in each of your enum values.
And thats a quick look at Enumerations in Objective-C.
