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];

return;

}

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

}

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

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

{

// 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.

UIButton Example in iPhone

Sushant — Tue, 22 Nov 2011 05:09:08 +0000

In this example we will see how to display DatePicker view after pressing button. So let see how it will worked.

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

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, Button_FunViewController.xib for the Button_Fun.

Step 4: We need to add one UIViewController class in the application. So select New File -> Cocoa Touch ->
UIViewController subclass, and give the class name “Date Picker”.

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

#import 

@class DatePicker;

@interface Button_FunViewController : UIViewController {

DatePicker *datePicker;

IBOutlet UIButton *button;

}

@property (nonatomic, retain) IBOutlet UIButton *button;

-(IBAction) nextview:(id)sender;

@end

Step 6: Double click the Button_FunViewController.xib file and open it to the Interface Builder. Drag the Round Rect
button from the library and place it to the view window. Select the button and bring up Connection Inspector connect Touch Up Inside to the File’s owner icon and select nextview: method. Now save the .xib file , close it and go back to the Xcode.

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

#import "Button_FunViewController.h"

#import "DatePicker.h"

@implementation Button_FunViewController

@synthesize button;

-(IBAction) nextview:(id)sender

{

datePicker = [[DatePicker alloc]

initWithNibName:@"DatePicker"

bundle:nil];

[self.view addSubview:datePicker.view];

}

- (void)dealloc

{

[super dealloc];

[datePicker release];

}

- (void)didReceiveMemoryWarning

{

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

[super didReceiveMemoryWarning];

}

- (void)viewDidUnload

{

[super viewDidUnload];

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

// Return YES for supported orientations

return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

@end

Step 8: Open the DatePicker.h file and make the following change:

#import 

@interface DatePicker : UIViewController {

IBOutlet UIDatePicker *datePicker;

}

-(IBAction) previousview:(id)sender;

@end

Step 9: Double click the DatePicker.xib file and open it to the Interface Builder. First drag the date picker from library and
place it to the view window. Connect File’s Owner icon to the DatePicker and select datePicker. Now drag the Round Rect
Button and place it to the view window. Select the button and bring up connection inspector and connect Touch Up Inside to the File’s owner icon and select previousview: method. Now save the .xib file, close it and go back to the Xcode.

Step 10: Open the DatePicker.m file and make the following changes:

#import "DatePicker.h"

@implementation DatePicker

-(IBAction) previousview:(id)sender;

{

[self.view removeFromSuperview];

}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

}

return self;

}

Now connect File’s Owner icon to the TextField and select text, select the button and bring up Connection Inspector and connect Touch Up Inside to the File’s Owner icon and select AlertView: method. Now Save the .xib file, close it and go back to the Xcode.

Step 6: Open the AlertViewViewController.m file and make the following changes:

#import "AlertViewViewController.h"

@implementation AlertViewViewController

- (IBAction)AlertView:(id)sender

{

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

{

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

message:@"Enter Your Name"

delegate:self

cancelButtonTitle:@"OK"

otherButtonTitles: nil];

[alert show];

}[

text resignFirstResponder];

}

- (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.

}

#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;

}
