Photos Application in iPhone

Sushant — Wed, 25 Jan 2012 09:41:24 +0000

In this application we will see how to multiple photos select from the photo gallery and we can display, rotate and swipe this photo in the view. So let see how it will worked.

Step 1: Open the Xcode, Create a new project using View Base application. Give the application “PhotosApp”.

Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory.

Step 3: Expand classes and notice Interface Builder created the ViewController class for you. Expand Resources and notice the template generated a separate nib, PhotosAppViewController.xib for the ImageClick application.

Step 4: We need to add the framework MobileCoreServices.framework

Step 5: Open the PhotosAppViewController.h file and make the following changes:

#import 

#import 

@interface PhotosAppViewController : UIViewController 
UIImagePickerControllerDelegate, UIPopoverControllerDelegate, UIGestureRecognizerDelegate>

{

CGFloat Scale;

CGFloat XPosition;

CGFloat YPosition;

}

-(IBAction)Photosadd:(id)sender;

@end

Step 6: Double click the PhotosAppViewController.xib file and open it to the interface Builder. Drag the Toolbar and Bar Button Item from the library and place it to the View window. Now select the button and bring up Connection Inspector and connect Touch Up Inside to the File’s Owner icon and select Photosadd: method and drag the label from library and place it to the view window and bring up Attribute Inspector change the text “Swipe Photos Here ” . Now Save the .xib file, close it and go back to the Xcode.

Step 7: Open the PhotosAppViewController.m file and make the following changes:

#import "PhotosAppViewController.h"

@implementation PhotosAppViewController

- (void)dealloc

{

[super dealloc];

}

- (void)didReceiveMemoryWarning

{

// Releases the view if it doesn’t have a superview.

[super didReceiveMemoryWarning];

// Release any cached data, images, etc that aren’t in use.

}

-(IBAction)Photosadd:(id)sender {

UIImagePickerController *controller = [[UIImagePickerController alloc] init];

[controller setMediaTypes:[NSArray arrayWithObject:kUTTypeImage]];

[controller setDelegate:self];

UIPopoverController *popover = [[UIPopoverController alloc]

initWithContentViewController:controller];

[popover setDelegate:self];

[popover presentPopoverFromBarButtonItem:sender

permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:

UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

UIView *holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, image.size.width,

image.size.height)];

UIImageView *imageview = [[UIImageView alloc] initWithFrame:[holderView frame]];

[imageview setImage:image];

[holderView addSubview:imageview];

UIPinchGestureRecognizer *pinchRecognizer = [[UIPinchGestureRecognizer alloc]

initWithTarget:self action:@selector(scale:)];

[pinchRecognizer setDelegate:self];

[holderView addGestureRecognizer:pinchRecognizer];

UIRotationGestureRecognizer *rotationRecognizer = [[UIRotationGestureRecognizer alloc]

initWithTarget:self action:@selector(rotate:)];

[rotationRecognizer setDelegate:self];

[holderView addGestureRecognizer:rotationRecognizer];

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc]

initWithTarget:self action:@selector(move:)];

[panRecognizer setMaximumNumberOfTouches:1];

[panRecognizer setDelegate:self];

[holderView addGestureRecognizer:panRecognizer];

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc]

initWithTarget:self action:@selector(tapped:)];

[tapRecognizer setNumberOfTapsRequired:1];

[tapRecognizer setDelegate:self];

[holderView addGestureRecognizer:tapRecognizer];

[self.view addSubview:holderView];

}

-(void)scale:(id)sender {

[self.view bringSubviewToFront:[(UIPinchGestureRecognizer*)sender view]];

if([(UIPinchGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded) {

Scale = 1.0;

return;

}

CGFloat scale = 1.0 - (Scale - [(UIPinchGestureRecognizer*)sender scale]);

CGAffineTransform currentTransform = [(UIPinchGestureRecognizer*)sender

view].transform;

CGAffineTransform newTransform = CGAffineTransformScale(currentTransform, scale,

scale);

[[(UIPinchGestureRecognizer*)sender view] setTransform:newTransform];

Scale = [(UIPinchGestureRecognizer*)sender scale];

}

-(void)move:(id)sender {

CGPoint translatedPoint = [(UIPanGestureRecognizer*)sender translationInView:self.view];

if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateBegan) {

XPosition = [[sender view] center].x;

YPosition = [[sender view] center].y;

}

translatedPoint = CGPointMake(XPosition+translatedPoint.x, YPosition+translatedPoint.y);

[[sender view] setCenter:translatedPoint];

if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded) {

CGFloat finalX = translatedPoint.x + (.35*[(UIPanGestureRecognizer*)sender

velocityInView:self.view].x);

CGFloat finalY = translatedPoint.y + (.35*[(UIPanGestureRecognizer*)sender

velocityInView:self.view].y);

if(UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation])) {

if(finalX < 0) {

finalX = 0;

}

else if(finalX > 768) {

}

}

[UIView beginAnimations:nil context:NULL];

[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

[[sender view] setCenter:CGPointMake(finalX, finalY)];

[UIView commitAnimations];

}

}

-(void)tapped:(id)sender {

[[[(UITapGestureRecognizer*)sender view] layer] removeAllAnimations];

}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer

shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer

ImageClick Application in iPhone

Sushant — Thu, 19 Jan 2012 10:30:55 +0000

In this application we will see how to image capture in iPhone without using camera. So let see how it will worked.

Step 1: Open the Xcode, Create a new project using View Base application. Give the application “ImageClick”.

Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory.

Step 3: Expand classes and notice Interface Builder created the ViewController class for you. Expand Resources and notice the template generated a separate nib, ImageClickViewController.xib for the ImageClick application.

Step 4: We need to add one image in the resource in the application. Give the name

Step 5: Open the ImageClickViewController.h file and make the following changes:

#import 

@interface ImageClickViewController : UIViewController {

UIImageView *image;

}

@property (nonatomic, retain) IBOutlet UIImageView *image;

-(IBAction)PhotoCapture:(id)sender;

@end

Step 6: Double click the ImageClickViewController.xib file and open it to the interface Builder. Drag the image view and round rect button from the library and place it to the View window. Now select the button and bring up Connection
Inspector and connect Touch Up Inside to the File’s Owner icon and select PhotoCapture: method and select the imageview and bring up Attribute Inspector and select the background image.Now Save the .xib file, close it and go back to the Xcode.

Step 7: Open the ImageClickViewController.m file and make the following changes:

#import "ImageClickViewController.h"

@implementation ImageClickViewController

@synthesize image;

- (void)dealloc

{

[super dealloc];

}

- (void)didReceiveMemoryWarning

{

// Releases the view if it doesn’t have a superview.

[super didReceiveMemoryWarning];

// Release any cached data, images, etc that aren’t in use.

}

-(IBAction)PhotoCapture:(id)sender

{

UIGraphicsBeginImageContext(image.frame.size);

[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

}

#pragma mark – View lifecycle

/*

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

- (void)viewDidLoad

{

[super viewDidLoad];

}

*/

- (void)viewDidUnload

{

[super viewDidUnload];

// Release any retained subviews of the main view.

// e.g. self.myOutlet = nil;

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

// Return YES for supported orientations

return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

@end

Step 8: Now Compile and run the application on the Simulator. Click the “Capture Snap” button, it will automatically capture the background image and save it in the photos.

EmailSend Application in iPhone

Sushant — Tue, 03 Jan 2012 10:40:08 +0000

In this application we will see how to Email Send in iPhone. So let see how it will
worked.

My last post you can find out from here (attached the previous post link)

Step 1: Open the Xcode, Create a new project using View Base application. Give the application “EmailSend”.

Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory.

Step 3: Expand classes and notice Interface Builder created the ViewController class for you. Expand Resources and notice the template generated a separate nib, EmailSendViewController.xib for the EmailSend application.

Step 4: We need to add MessageUI.framework in the application.

Step 5: Open the EmailSendViewController.h file and make the following changes:

#import 

#import 

@interface EmailSendViewController : UIViewController

{

}

- (IBAction)SendMail:(id)sender;

@end

Step 6: Double click the EmailSendViewController.xib file and open it to the interface Builder. Drag the round rect button from the library and place it to the View window. Now select the button and bring up Connection Inspector and connect Touch Up Inside to the File’s Owner icon and select SendMail: method. Now Save the .xib file, close it and go back to the Xcode.

Step 7: Open the AlertViewViewController.m file and make the following changes:

#import "EmailSendViewController.h"

@implementation EmailSendViewController

- (void)dealloc

{

[super dealloc];

}

- (void)didReceiveMemoryWarning

{

// Releases the view if it doesn’t have a superview.

return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

- (IBAction)SendMail:(id)sender

{

if ([MFMailComposeViewController canSendMail])

{

MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];

mailer.mailComposeDelegate = self;

[mailer setSubject:@"A Message from iPhone"];

NSArray *toRecipients = [NSArray arrayWithObjects:@"", @"", nil];

[mailer setToRecipients:toRecipients];

NSString *emailBody = @"Have you Nice Day";

[mailer setMessageBody:emailBody isHTML:NO];

// only for iPad

// mailer.modalPresentationStyle = UIModalPresentationPageSheet;

[self presentModalViewController:mailer animated:YES];

[mailer release];

}

else

{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Failure"

message:@"Your device doesn’t support the composer sheet"

delegate:nil

cancelButtonTitle:@"OK"

otherButtonTitles: nil];

[alert show];

[alert release];

}

}

#pragma mark – MFMailComposeController delegate

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:

(MFMailComposeResult)result error:(NSError*)error

{

switch (result)

{

case MFMailComposeResultCancelled:

NSLog(@"Mail cancelled");

break;

NSLog(@"Mail saved");

break;

case MFMailComposeResultSent:

NSLog(@"Mail send");

break;

case MFMailComposeResultFailed:

NSLog(@"Mail failed");

break;

default:

NSLog(@"Mail not sent");

break;

}

[self dismissModalViewControllerAnimated:YES];

}

@end

Step 8: Now Compile and run the application on the Simulator.

PhoneGap is an HTML5 app that allow you to author native applications with web technologies and get access to APIs. We need to installed PhoneGap in Xcode 4. For that follow the below requirment:

1. Installed PhoneGap 1.0.0 form here

2. Close the Xcode before you download the PhoneGap.

My Last post you can find out from here TextScroll

Step 1: Open the Xcode, Create a new project using PhoneGap based application. Give the application “iPhoneGap”(See the figure 1).

Figure 1

Step 2: Xcode automatically creates the directory structure and adds essential frameworks to it. You can explore the directory structure to check out the content of the directory (Image should be figure2).

Figure 2

Step 3: If you compile and run the application, you got the error in the simulator “ERROR: Start page at www/index.html was not found”.

Step 4: Select the Project and open it to the finder (See the figure 3). You can find out www folder (See figure 4).

Figure 3

Figure 4

Step 5: Drag the www folder in the project, but make sure you select the “Create folder references foe any added folders (See figure 5).
