Create a Global access for variable and array instead of AppDelegate declaration:

1. Create a NSObject class

Ex:

Globalclass.h

#import <Foundation/Foundation.h>

@class Globalclass; //create a global class name

extern Globalclass *Global; // create a instance for global class

@interface Globalclass : NSObject

{

NSMutableArray *Pointarray1; // global array declaration

}

@property(nonatomic,readwrite) NSMutableArray *Pointarray1;

+(void)globalaccess; // create a class method

@end

Globalclass.m

#import "Globalclass.h"

Globalclass *Global; // create a instance for global class

@implementation Globalclass

@synthesize Pointarray1;

+(void)globalaccess

{

Global=[[Globalclass alloc]init]; // allocate global class

}

@end

ViewController.m

#import "ViewController.h"

#import "Tableview.h"

#import "Globalclass.h" // import Global class

@interface ViewController ()

@end

@implementation ViewController

@synthesize btn;

- (void)viewDidLoad

{

[Globalclass globalaccess]; // To call global class method

Global.Pointarray1=[[NSMutableArray alloc]init]; // initate the created global array

[super viewDidLoad];

}

-

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

UITouch *touch ;

touch = [[event allTouches] anyObject];

if ([touch view] == self.view){

CGPoint location = [touch locationInView:touch.view];

UIImageView *img1=[[UIImageView alloc]init];

[img1 setImage:[UIImage imageNamed:@"bluedot.gif"]];

img1.frame=CGRectMake(2, 2,location.x,location.y);

[self.view addSubview:img1];

NSLog(@"point........ %f .. %f",location.x,location.y);

[Global.Pointarray1 addObject:[NSString stringWithFormat:@"X=%f,Y=%f",location.x,location.y]];

// To access the created array

NSLog(@"point array==>%@",Global.Pointarray1);

}

}

Tableview.m

#import "Tableview.h"

#import "Globalclass.h" // import Global class

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

// Return the number of rows in the section.

return [Global.Pointarray1 count];

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {

cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

}

// Configure the cell...

NSString *cellValue = [Global.Pointarray1 objectAtIndex:indexPath.row]; // display the array value in table view.

cell.textLabel.text = cellValue;

return cell;

}

To Create the appDelegate variable and Access for Xcode 4.5

AppDelegate.h

@interface AppDelegate : UIResponder <UIApplicationDelegate>

{

NSMutableArray *testArray;

}

@property(nonatomic,retain)NSMutableArray *testArray;

AppDelegate.m

@synthesize testArrayName;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

testArrayName = [[NSMutableArray alloc]init];

}

ViewController.h

#import <UIKit/UIKit.h>

@class appDelegate;

@interface ViewController : UIViewController

{

appDelegate *appdelegate;

}

ViewController.m

#import "ViewController.h"

#import “ appDelegate.h”

- (void)viewDidLoad

{

appdelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];

}

To access the appdelegate varaable

Ex:

NSString *Desp=[appdelegate.arrayDescList objectAtIndex:appdelegate.objid1];

Simple NavigationController one Xib to another Xib for iOS 6.0 Simulator

AppDelegate.h

#import <UIKit/UIKit.h>

@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

{

UIWindow *window;

ViewController *viewController;

UINavigationController *navi;

}

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;

@end

AppDelegate.m

#import "AppDelegate.h"

#import "ViewController.h"

@implementation AppDelegate

@synthesize window,viewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

// Override point for customization after application launch.

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil];

} else {

self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil];

}

navi=[[UINavigationController alloc]initWithRootViewController:viewController];

[navi setNavigationBarHidden:YES animated:YES];

[window addSubview:navi.view];

[self.window makeKeyAndVisible];

return YES;

}

ViewController.m

#import "ViewController.h"

#import "TableViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize btn;

- (void)viewDidLoad

{

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

-(IBAction)btn_Clicked:(id)sender

{

NSLog(@"clicked");

TableViewController *nextView=[[TableViewController alloc]init]; // Which xib want to push

[self.navigationController pushViewController:nextView animated:YES];

}

3.Use one UIAlertView to pass the string parameter to display multiple way Alert Message//.

-(void)Show_Alert:(NSString*)strMessage

{

    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:strMessage delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

    [alertView show];

}

// some method here

     if ([txtSchDate.text length]==0)

        {

            [self Show_Alert:@"Please select schedule date"];return;

        }

        if ([txtSchStartTime.text length]==0)

        {

            [self Show_Alert:@"Please select Start Time"];return;

        }

        if ([txtSchEndTime.text length]==0)

        {

            [self Show_Alert:@"Please select End Time"];return;

        }

2.Type casting UIText field using tag values assign the border color…[ Use custom UIView class]

 UITextField *txtAddressLine1Ref = (UITextField*)[self viewWithTag:4]; //txtAddressLine1

        

        txtAddressLine1Ref.layer.borderColor = [[UIColor colorWithRed:197.0f/255.0f green:215.0f/255.0f blue:224.0f/255.0f alpha:1]CGColor];

        txtAddressLine1Ref.layer.borderWidth = 1.0f;

1.How to get the subview from parent view To accès thé subview control Ex UITextview hère code

for (UIView *viewTemp in [viewContentToMoveBottom subviews]) // [self subviews]

    {

        if ([viewTemp isKindOfClass:[UITextView class]]) // which control going to check

        {

          NSLog(@"loop enter 3 ");   

            

            UITextView *txtView = (UITextView*)viewTemp;

            

            if (txtView.tag==700)

            {

                NSLog(@"loop enter1 ");

                

                txtView.layer.borderColor = [[UIColor redColor]CGColor];

                txtView.layer.borderWidth = 1.0f;

                

                

            }

            

            else

            {

                txtView.layer.borderColor = [[UIColor colorWithRed:197.0f/255.0f green:215.0f/255.0f blue:224.0f/255.0f alpha:1]CGColor];

                        txtView.layer.borderWidth = 1.0f;

            }

        }

    }

Flash Screen:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

CGRect appFrame = CGRectMake(0, 0, 320, 460);

UIView *view = [[UIView alloc] initWithFrame:appFrame];

myView = view;

view.backgroundColor = [UIColor redColor];

view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;

splashImgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Default.png"]];

splashImgView.frame=myView.frame;

//timer = [NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(fadeScreen) userInfo:nil repeats:NO];

[myView addSubview:splashImgView];

[self.window addSubview:myView];

}

- (void)fadeScreen

{

NSLog(@"fadeScreen");

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:0.75];

[UIView setAnimationDelegate:self];

//[UIView setAnimationDidStopSelector:@selector(finishedFading)];

myView.alpha = 2.0;

[UIView commitAnimations];

}
