/*Signlton.h starts*/

#import <Foundation/Foundation.h>

void ALERT(NSString *title, NSString *message,NSString *canceBtnTitle,id delegate,NSString *otherButtonTitles, … );

@interface Signlton : NSObject

{

NSMutableArray *contentArray;

}

– (NSMutableArray *) getArray;

– (void) addArray:(NSMutableArray *)mutableArray;

+(id) instance;

+(id) sharedInstance;

+(id) singleton;

@end

/*Signlton.h ends*/

/*Signlton.m starts*/

#import “Signlton.h”

@implementation Signlton

static NSMutableDictionary* _children;

void ALERT(NSString *title, NSString *message,NSString *canceBtnTitle,id delegate,NSString *otherButtonTitles, … )

{

UIAlertView *alertView=[[UIAlertView alloc] initWithTitle:title

message:message

delegate:delegate

cancelButtonTitle:canceBtnTitle

otherButtonTitles:nil

];

va_list args;

va_start(args, otherButtonTitles);

[alertView addButtonWithTitle:obj];

va_end(args);

[alertView show];

[alertView release];

}

+(void) initialize //thread-safe

{

if(!_children) {

_children = [[NSMutableDictionary alloc] init];

}

[_children setObject:[[self alloc] init] forKey:NSStringFromClass([self class])];

}

+(id) alloc {

id c;

if((c = [self instance])) {

return c;

}

return [self allocWithZone:nil];

}

-(id) init {

id c;

if((c = [_children objectForKey:NSStringFromClass([self class])])) { //sic, unfactored

return c;

}

if(self = [super init]){

contentArray = [[NSMutableArray alloc] init];

}

return self;

}

+(id) instance {

return [_children objectForKey:NSStringFromClass([self class])];

}

+(id) sharedInstance { //alias for instance

return [self instance];

}

+(id) singleton {      //alias for instance

return [self instance];

}

– (NSMutableArray *) getArray{

return contentArray;

}

– (void) addArray:(NSMutableArray *)mutableArray{

[contentArray addObject:mutableArray];

}

//stop other creative stuff

+(id) new {

return [self instance];

}

+(id)copyWithZone:(NSZone *)zone {

return [self instance];

}

+(id)mutableCopyWithZone:(NSZone *)zone {

return [self instance];

}

@end

/*Signlton.m ends*/

/* Now How to use this in your class */

/*ViewController.m starts*/

#import “ViewController.h”

#import “Signlton.h”

@interface ViewController ()

@end

@implementation ViewController

– (void)viewDidLoad

{

[super viewDidLoad];

// if you want to deal with array then and then only use below code

Content *content = [Content sharedInstance];// this is not neccesory for UIAlertView method

[content addArray:mArray];

NSLog(@”contentArray: %@”, [content getArray]);

}

-(IBAction)CallAlert
