Creating Switch, Web and Scroll views in iPhone

Switching views :-

. h file:-

[1. Using Present model view Controller]

# import <UIKIT/UIKIT. H>

# import   “SecondviewController. h”

@ interface Switching view Controller: UIViewController

{

}

-(IBAction) next clicked;

 @ end

.m file:-

# import “Switching viewController .h”

@ implementation Switchingview Controller

-( IBAction)  nextClicked

{

SecondviewController    * second = [[ SecondviewController alloc]

InitwithNibName:  @  “SecondViewController” bundle :nil];

[ self PresentModelviewController : Second animated: YES];

}

Second view controller. M:-

-(IBAction) backClicked

{

[ self dismissModel  viewControllerAnimated : YES];

}

Second viewController:-

# import <UIKIT/UIKIT .h>

@ interface Second view Controller : UIviewController

{

}

-(IBAction) backclicked;

@ end

[ 2: by using adding sub views ]

[  self view add subview.v1];

[ self view removesubview:v1];

WEB VIEW:-

-(void) viewDidLoad

{

UIWebView  *webView=  [[UIWebView  alloc]

InitWithFrame  : CGRectMake  (0,44,320,436)];

NSURL       *url   =   [ NSURL URLWithString  :@

                                     .http :// www.google.com”];

NSURLRequest     * request  =   [NSURL Request

                                                           RequestWithURL: url];

[web view loadRequest: request];

Webview: delegate  =  Self;

[  self. View  addSub view:  web view];

[ web view release];

// Loading Previous:

If (web view canGoBack)

   [webview  goBack];

// loading forward action:

If ( web view . canGoForward)

   [ web view go forward];

// is web view in loading:

If (webview. Loading)

{

// in loading.

}

[ super viewDidLoad];

}

# Program Mark UI Web View Delegate Methods:

-(void)  webviewDidStartLoad  :  (UIwebview   *)  webview

{

NSLog (@   “ webviewDidstartLoad called”);

}

-(void) webviewDidFinishload:  (UIwebview   *) webview

{

NSLog (@  “  webviewFinishload   called”);

}

-(void) webview  :  (UIwebview     *)   webview.

DidfailloadwithError: (NSError     *)  error

{

NSLog (@   “did fail load  with error called”);

}

Scroll view:-

Scroll views are created as any other view is, either programmatically or in Interface Builder. Only a small amount of additional configuration is required to achieve basic scrolling capabilities.

1. Scroll for image
2. Scroll for views

1. Scroll for images:-

. h file:-

# import   <UIKIT/UIKIT . h>

@ interface  ScrollView Viewcontroller  :   UIViewController

{

IBoutlet     UIScrollview        *Scroll;

IBoutlet      UIImageview    * imageView;

}

@ end

.m file:-

-(void) viewDidLoad

{

UIImage     *img  =  [ UIImage Named.

                     @  “photo  on 2011-07-03 at 10.28.jpg”];

CGSize Size =  img.  Size;

Img view. Frame  =  CGRectMake  (0,0 size. Width,  size. Height);

Img  view. Image    =   img;

[ Scroll    addSubview: imgview];

[ scroll setContentSize: img. Size];

}

Xib file:-

Dynamically Adding img view to Scroll View :-

-(void) viewDidLoad

{

UIScrollview       *Scroll  =  [[ UIScroll view alloc ]

InitWithFrame  :  [  UIScreenmainScreen]. application Frame];

UI image   *img  =  [UI image image named:@ “1.jpg”];

CG size   size  =  img .size;

UI image view   * img view  =[[UI image  view  alloc]

Init with frame : CG rect make (0,0 size width , size height)];

Img view image   = img;

[  Scroll addSub view: img view];

// Setting Content Size

Scroll. ContentSize   =   imgview. frame. Size;

[  Self . view  addSub view :Scroll];

[  img view        release];

[  Scroll             release];

[ Super              view did load];

}              

2. Scroll for view:-

.h file:-

# import <UIKIT/UIKIT .h>

@ interface  Scrollview viewController: UIviewController

{

IBoutlet   UIScroll view  * Scroll;

IBoutlet    UIView     *     Signupview;

}

.m file:-

-(void) viewDidLoad

{

[scroll    addSubview: Signupview];

Scroll. Contentsize   =   Signupview .frame .Size;

}
