ios - How to create an NSMutableArray and assign a specific object to it? -

i getting obj c, , looking create array of mkannotations.

i have created mkannotation class called trucklocation contains name, description, latitude, , longitude.

here have far array:

nsmutablearray* trucksarray =[nsmutablearray arraywithobjects: @[<#objects, ...#>]  nil];

yore trying combine 2 different syntaxes similar different things. don't seem have instances of annotations.

create instances

trucklocation *a1 = ...; trucklocation *a2 = ...;

then can add them

nsmutablearray *trucksarray = [nsmutablearray arraywithobjects:a1, a2, nil];

nsmutablearray *trucksarray = [@[a1, a2] mutablecopy]

this shorter , more modern form need make mutable create immutable instance.
