how and where do I initialize an global NSMutableArray in Xcode 5

Question

I am trying to initialize a global NSMutableArray that I can add integers to later. I just need to know how and where I should initialize my array so that it can be accessed

Answer 1

You could create a singleton class and define a property for your array on that class.

for example:

// .h file
@interface SingletonClass : NSObject
@property (nonatomic,retain) NSMutableArray *yourArray; 
+(SingletonClass*) sharedInstance;
@end

// .m file

@implementation SingletonClass

+(SingletonClass*) sharedInstance{
    static SingletonClass* _shared = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _shared = [[self alloc] init];
        _shared.yourArray = [[NSMutableArray alloc] init];
     });
     return _shared;
  }

@end
