Question

I tried to create a singleton to set and get a string between different views:

globalVar.h:

@interface globalVar : NSObject
{
    NSString *storeID;
}

+ (globalVar *)sharedInstance;
@property  (nonatomic, copy) NSString *storeID;
@end

globalVar.m:

#import "globalVar.h"

@implementation globalVar
@synthesize storeID;

+ (globalVar *)sharedInstance
{
       static globalVar *myInstance = nil;    

    if (nil == myInstance) {
        myInstance  = [[[self class] alloc] init];        
    }
    return myInstance;
}
@end

Now how do I actually use the string? Say I want to set it to “asdf” in one view and load the “asdf” in another view.

Answer 1

To set it, do something like:

[globalVar sharedInstance].storeID = @"asdf";

And to use it:

NSString *myString = [globalVar sharedInstance].storeID;
