how to make custom segmented control?

Hi,
Many of you want to make custom controls in their own projects but sometime they need some guidance or the way to customize those controls. So, here is the way for everyone who wants to make his/her own custom segmented control in iPhone, iPad projects. Please follow the below steps :

Step 1 : Import these two files in your projects . ("CustomsegmentControl.h","CustomsegmentControl.m")

#import <UIKit/UIKit.h>

@interface CustomSegmentControl : UISegmentedControl
{
    UIColor *unselectedColor,*selectedColor;
}
@property (nonatomic,retain) UIColor *unselectedColor,*selectedColor;
-(id)initWithItems:(NSArray *)items unselectedColor:(UIColor*)unselectedColor selectedColor:(UIColor*)selectedColor;
@end


#import "CustomSegmentControl.h"

@interface CustomSegmentControl(private)
-(void)setupInitialMode;
-(void)switchHighlightColors;
@end

@implementation CustomSegmentControl

@synthesize unselectedColor,selectedColor;

-(id)initWithItems:(NSArray *)items unselectedColor:(UIColor*)unselectedColor selectedColor:(UIColor*)selectedColor {
    if (self = [super initWithItems:items])
    {
        // Initialization code
        self.unselectedColor = unselectedColor;
        self.selectedColor = selectedColor;
        [self setInitialMode];
        [self setSelectedSegmentIndex:0];
    }
    return self;
}
- (void)awakeFromNib
{
    self.unselectedColor = [UIColor colorWithWhite:0.7 alpha:1];
    self.selectedColor = self.tintColor;
    [self setInitialMode];
   
    [self setSelectedSegmentIndex:0];
}

-(void)setupInitialMode
{
    [self setBackgroundColor:[UIColor clearColor]];
    [self setSegmentedControlStyle:UISegmentedControlStyleBar];
   
    for( int i = 0; i < [self.subviews count]; i++ )
    {
        [[self.subviews objectAtIndex:i] setTintColor:nil];
        [[self.subviews objectAtIndex:i] setTintColor:unselectedColor];
    }
    [self addTarget:self action:@selector(switchHighlightColors) forControlEvents:UIControlEventValueChanged];
}


-(void)switchHighlightColors
{
    for (id view in self.subviews) {
        if ([view isSelected]) [view setTintColor:selectedColor];
        else [view setTintColor:unselectedColor];
    }
}

- (void)setSelectedSegmentIndex:(NSInteger)selectedSegmentIndex
{
    [super setSelectedSegmentIndex:selectedSegmentIndex];
    [self switchHighlightColors];
}
@end

Step 2 :  Now make your new custom segment control in the class file wherever you want to use that custom control. 

For example : CustomSegmentControl *obj_customsegment;

obj_customsegment = [[CustomSegmentControl alloc]initWithItems:[NSArray arrayWithObjects:@"One",@"Two",nil] unselectedColor:[UIColor blackColor] selectedColor:[UIColor blueColor]];


Now, you can easily use above custom segment control object in your project.

how to change the selected segment button color ?

Hi all,
Please use the below code if you want to change the color of UISegmentedControl's component after the selection of that rather showing the default color.

For example : 

UISegmentedControl *segmentedControl; // You can use your own segmented control rather using this one...

UIColor *selectedColor = [UIColor colorWithRed: 0.0f/255.0 green:0.0f/255.0 blue:255.0f/255.0 alpha:1.0];
         UIColor *deselectedColor = [UIColor colorWithRed: 0.0f/255.0 green: 0.0f/255.0 blue: 255.0/255.0 alpha:0.2];

for (id subview in [segmentedControl subviews]) {
    if ([subview isSelected])
       [subview setTintColor:selectedColor];
    else
       [subview setTintColor:deselectedColor];
}

how to add gradient effect to button in iphone?

Hi friends,
If anyone, of you, want to add gradient effect to custom button then here is the way to add that effect.

Example :

        // Add Border to button
        CALayer *layer = btnCalender.layer;
        layer.cornerRadius = 5.0f;
        layer.masksToBounds = YES;
        layer.borderWidth = 1.0f;
        layer.borderColor = [UIColor colorWithWhite:0.3f alpha:0.2f].CGColor;
       
        // Add Shine to button
        CAGradientLayer *Layer = [CAGradientLayer layer];
        Layer = layer.bounds;
        Layer.colors = [NSArray arrayWithObjects:
                             (id)[UIColor colorWithWhite:1.0f alpha:0.4f].CGColor,
                             (id)[UIColor colorWithWhite:1.0f alpha:0.2f].CGColor,
                             (id)[UIColor colorWithWhite:0.75f alpha:0.2f].CGColor,
                             (id)[UIColor colorWithWhite:0.4f alpha:0.2f].CGColor,
                             (id)[UIColor colorWithWhite:1.0f alpha:0.4f].CGColor,
                             nil];
        Layer.locations = [NSArray arrayWithObjects:
                                [NSNumber numberWithFloat:0.0f],
                                [NSNumber numberWithFloat:0.2f],
                                [NSNumber numberWithFloat:0.3f],
                                [NSNumber numberWithFloat:0.0f],
                                [NSNumber numberWithFloat:1.0f],
                                nil];
        [layer addSublayer: Layer];

    [webViewVideo setBackgroundColor:[UIColor redColor]];
   
    UIButton* b=(UIButton*)sender;
   
    NSString* urlString=[array_Youtube objectAtIndex:b.tag];
   
    NSString *embedHTML = @"\
    <html><head>\
    <style type=\"text/css\">\
    body {\
    background-color: transparent;\
    color: white;\
    }\
    </style>\
    </head><body style=\"margin:0\">\
    <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" allowscriptaccess=\"always\" allowfullscreen=\"true\" \
    width=\"%0.0f\" height=\"%0.0f\"></embed>\
    </body></html>";
    NSString *html;
    html = [NSString stringWithFormat:embedHTML, urlString, 768.0, 500.0];
       
    [webViewVideo loadHTMLString:html  baseURL:nil];

How to integrate live audio streaming in iPhone?

Hi everyone,
I think, all of you heard about live audio/video streaming. I'm going to share "Live Audio Streaming" example with you.
Please check this :

Step 1: First of all, you have to download these two files(AudioStreamer.h, AudioStreamer.m) from http://code.google.com/p/audiostreamer-meta/source/browse/trunk/Classes

Step 2: Add necessary frameworks and above two files into your project.

Step 3: Implement below code to your project file.

@class AudioStreamer;

@interface CallerTuneListViewController : UIViewController
{
    AudioStreamer *streamer;
}

#import "CallerTuneListViewController.h"

#import "AudioStreamer.h"
#import <QuartzCore/CoreAnimation.h>
#import <MediaPlayer/MediaPlayer.h>
#import <CFNetwork/CFNetwork.h>
#import <AudioToolbox/AudioToolbox.h>

@implementation CallerTuneListViewController

#pragma mark ---------------------------------
#pragma mark View LifeCycle

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    if ([streamer isPlaying]) {
        [self destroyStreamer];
    }
}

#pragma mark ---------------------------------
#pragma mark Memory Management

            if (![streamer isPlaying])
                {
                    [self createStreamer:AudioFilePath];
                    [streamer start];
                }
                else
                {
                    [streamer stop];
                }
}


#pragma mark ---------------------------------
#pragma mark AudioStreamer Methods

// Removes the streamer, the UI update timer and the change notification

How to add custom fonts to iPhone application?

Hi,

As of iOS 4.0 and later iOS version came, it has become very easy to add custom fonts to your iPhone/iPad/iPod applications. Here, some steps you have to follow in order to add custom fonts:

    1.    Add your custom font files into your project using XCode as a resource
    2.    Add a key to your info.plist file called UIAppFonts.
    3.    Make this key an array
    4.    For each font you have, enter the full name of your font file (including the extension) as items
           to the UIAppFonts array.
    5.    Save info.plist
    6.    Now in your application you can simply call
           [UIFont  fontWithName:@"CustomFontName" size:FontSize]
           to get the custom font to use with your UILabels and UITextViews, etc…

It’s very simple to integrate!

How to move an object using touch event in iPhone?

Hello friends,
Here is the example regarding moving an object in Objective C or iPhone/iPad/iPod development.


#import <UIKit/UIKit.h>

@interface ImageMoveViewController : UIViewController
{
    IBOutlet UIImageView *photo;
}

@end


#import "ImageMoveViewController.h"

@implementation ImageMoveViewController

/*
 Implement viewDidLoad if you need to do additional setup after loading the view.
 - (void)viewDidLoad {
 [super viewDidLoad];
 }
 */

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    // get touch event
    UITouch *touch = [[event allTouches] anyObject];
    CGPoint touchLocation = [touch locationInView:self.view];
   
    if ([touch view] == photo) {
        // move the image view
        photo.center = touchLocation;
    }
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

UIPanGestureRecognizer scrolling example for iOS

Hi everyone,

Today, I'm giving you the source code of UIPanGestureRecognizer for iPhone.

Follow 2-3 simple steps as given below:

1) Put below code into your .header file of any viewcontroller class.

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UIGestureRecognizerDelegate>
{
    IBOutlet UIView *viewOrange;
    IBOutlet UIView *viewBrown;
    IBOutlet UIView *viewPurple;
}
@property(nonatomic,retain) IBOutlet UIView *viewOrange;
@property(nonatomic,retain) IBOutlet UIView *viewBrown;
@property(nonatomic,retain) IBOutlet UIView *viewPurple;

@end

2) Put below code into your .m file of same viewcontroller class.

#import "ViewController.h"

@implementation ViewController
@synthesize viewOrange;
@synthesize viewBrown;
@synthesize viewPurple;

CGPoint translatedPoint;
NSInteger _firstX;
NSInteger _firstY;
NSInteger numberofView;
CGSize viewSize;
float currentView;

BOOL isBegan;


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
  
    numberofView = 3;
    viewSize = CGSizeMake(320.0, 480.0);
   
    viewOrange.frame = CGRectMake(0.0, 0.0, 320.0, 480.0);
    viewPurple.frame = CGRectMake(320.0, 0.0, 320.0, 480.0);
    viewBrown.frame = CGRectMake(640.0, 0.0, 320.0, 480.0);
   
    UISwipeGestureRecognizer *swipegestureRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipe:)];
    [swipegestureRecognizer setDelegate:self];
    [self.view addGestureRecognizer:swipegestureRecognizer];
    [swipegestureRecognizer release];

}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;

how to detect link in UIWebview?

Hi friends,
Again I'm here to share something new with you.. If you want to do some operations on URL click in UIWebview of iPhone/iPod/iPad then you need to use the below delegate method of UIWebview. You have to set WebViewDelegate in header file of your class.


#pragma mark-------------------------
#pragma mark WebView Delegate Method

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSURL *url = request.URL;
    NSString *urlString = url.relativeString;
    NSLog(@"%@",urlString);
    NSLog(@"%@",[request.URL lastPathComponent]);
    if (navigationType == UIWebViewNavigationTypeLinkClicked)
    {
        if([[urlString substringToIndex:5] isEqualToString:@"https"] || [[urlString substringToIndex:5] isEqualToString:@"http:"])
        {
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString: urlString]];
        }
        else
        {
               // do your operation within Application
        }
        return NO;
    }
    return YES;
}

In-App Purchase Tutorial in iPhone

Hi,
Everyone, 

Here, I'm going to start the explanation for In-App Purchase for non-consumable product in iPhone/iPad. 

 You have to follow the below steps before you implement the code given below:

 After Creating new APP Id and making In-App Purchase Enabled , You have to create product identifier for non-consumable purchase and need to fill all required information .

After completion all process to itunesconnect.apple.com, you can implement the below code into you project file.

#import <StoreKit/StoreKit.h>
#define kMyFeatureIdentifier @"" //Product Identifier in In-App Purchase

@interface AppDelegate : UIResponder <UIApplicationDelegate,SKPaymentTransactionObserver ,SKRequestDelegate, SKProductsRequestDelegate>
{
    NSArray *arrPurchaseProducts;
    SKProduct *product;
}



#import "AppDelegate.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if([SKPaymentQueue canMakePayments])
    {
