iOS Singleton Class

To set values, use the below code.

YourSingletonClass *sharedManager = [YourtSingletonClass sharedManager];

sharedManager.nameString =@"name";

sharedManager.emailString =@"name@domain.com";

For getting values, use the below code

YourSingletonClass *sharedManager = [YourtSingletonClass sharedManager];

NSString *nameVal=sharedManager.nameString;

NSString *emailVal=sharedManager.emailString;

/////YourSingletonClass.h class

#import

@interface YourSingletonClass : NSObject{

    NSString *nameString;

    NSString *emailString;

}

@property (nonatomic, strong) NSString *nameString;

@property (nonatomic, strong) NSString *emailString;

+ (id)sharedManager;

@end

/////YourSingletonClass.m class

#import "YourSingletonClass.h"

@implementation YourSingletonClass

@synthesize nameString;

@synthesize emailString;

+ (id)sharedManager {

    static YourSingletonClass *sharedMyManager = nil;

    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{

        sharedMyManager = [[self alloc] init];

    });

    return sharedMyManager;

}

- (id)init {

    if (self = [super init]) {

        self.nameString = @"";

        self.emailString = @"";

    }

    return self;

}

- (void)dealloc {

    // Should never be called, but just here for clarity really.

}
