    [helper addTextField:self.txt1];

    [helper addTextField:self.txt3];

    [helper addTextField:self.txt2];

//  Here tab order is txt1 --> txt3 --> txt2 . You can change it.

    [helper addButtonWithTitle:@"Next" forEvent:MoveToNext];

// Two methods are provided. MoveToNext and MoveToBack

//  MoveToNext method is used to move cursor from one text field to next field.

//  MoveToBack method is used to move cursor from one text field to previous field.

   [helper addButtonWithTitle:@"Test" forCustomHandler:@selector(testtask)];

// You can also make your custom handler. Here we have made a method named testtask. We need to implement this method later.

// You can also set the image instead of giving title as 

 [helper addButtonWithImage:[UIImage imageNamed:@"imageName.png"] forEvent:MoveToNext];

   

// Finally call the method to set your custom key board.

        [scrollView addSubview:imageView];

        

        // adding image view to the scroll view

    }

    

    CGSize scrollViewSize=CGSizeMake(scrollView.frame.size.width*[imageArray count], scrollView.frame.size.height);

    

    // getting the content size of scroll view

    

    [scrollView setContentSize:scrollViewSize];

    // setting content size of scroll view

    

    [self.view addSubview:scrollView];

    

    // finally add scroll view to your view

}

How to store values in keychain of ios

How to store values in keychain of ios

Tutorial for: Key chain, user defaults, values, KeychainItemWrapper, iphone, ios

What is keyChain -

Key chain is the place where we can store the values which will be retain even after deleting application. Generally we store username and password in it.

Difference between KeyChain and userDefaults

The values which are store in userDeafults are deleted when we delete the app from our device but the values stored in KeyChain will not.


Apple provides helper classes, for that you can refer to this link
htps://developer.apple.com/library/ios/#samplecode/GenericKeychain/Introduction/Intro.html#//apple_ref/doc/uid/DTS40007797

Or you can download it from here

Initialise the class

KeychainItemWrapper *wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"Your application name" accessGroup:nil];

How to save the values

[wrapper setObject:@"PASSWORD" forKey:@"KEYPASS"];
[wrapper setObject:@"USERNAME" forKey:@"KEYUSER"];

how to retrive the values

NSString *pwd = [wrapper objectForKey:@"KEYPASS"];
NSString *user = [wrapperobjectForKey:@"KEYUSER"];

How to delete the values

[wrapper resetKeychainItem];

       How to implement hot search on tableView in iPhone

You can download the source code from here

1)   Take a new project named TableSearch

2)  Add Table in viewController.xib named tbl;

3) Add a search bar named searchBar

4) Set UITableViewDataSource,UITableViewDelegate and UISearchBarDelegate to support Delegate methods.

4) Modify the code of ViewController.h (Modified code is in different color - brown )

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDataSource,UITableViewDelegate,UISearchBarDelegate,UITextFieldDelegate>

{

    NSMutableArray *tableArray; // stores all data

    NSMutableArray *displayArray; // shows data on table

}

@property (retain, nonatomic) IBOutlet UISearchBar *serchBar;

@property (retain, nonatomic) IBOutlet UITableView *tbl;

@end

4)Now modify the code of ViewController.m (Modified code is in different color - brown )

How To Use shouldAutoRotate With Tab Bar controller in iOS6

To Support tabBarController auto Rotation in iOS6. You need to make category for that.

Add new file in you project named UITabBarController+autoRotate. File should be subclass of NSObject.

Modified the code of  UITabBarController+autoRotate.h as 

#import <UIKit/UIKit.h>

@interface UITabBarController (autoRotate)<UITabBarControllerDelegate>

-(BOOL)shouldAutorotate;

- (NSUInteger)supportedInterfaceOrientations;

@end

And Modified the code of  UITabBarController+autoRotate.m as 

#import "UITabBarController+autoRotate.h"

#import "AppDelegate.h"// 

@implementation UITabBarController (autoRotate)

-(BOOL)shouldAutorotate {

    

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

    return [delegate.tabBarController.selectedViewController shouldAutorotate];

}

- (NSUInteger)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskAll;

}

@end

Thats it.

Note: you may have to change name of AppDelegate With your Project AppDelegate name.
