I am new in twitter implementation, in my application there is one login screen, I want to give an option of twitter login also ,means user can also login from his twitter account.
please give some useful tips, How to do this.
You can use TwitterShare files.
TwitterShare.h
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#import <Twitter/Twitter.h>
#import <Accounts/Accounts.h>
#interface TwitterShare : UIViewController
{
TWTweetComposeViewController *_tweetSheet;
}
#property (nonatomic, retain) TWTweetComposeViewController *_tweetSheet;
- (void)buildTweetSheet:(UIView*) viewOnWhichToShow;
-(void)share:(UIImage*)imageToUpload viewOnWhichToShow:(UIView*) viewOnWhichToShow;
#end
TwitterShare.m
#import <MobileCoreServices/UTCoreTypes.h>
#import "TwitterShare.h"
#import "ProgressIndicator.h"
#implementation TwitterShare
#synthesize _tweetSheet;
#pragma mark -
#pragma mark View methods
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
#pragma mark -
#pragma mark Showing Tweet Sheet
- (void)buildTweetSheet:(UIView*) viewOnWhichToShow
{
/* make instance of tweet sheet */
_tweetSheet = [[TWTweetComposeViewController alloc] init];
/* Specify the completion handler */
TWTweetComposeViewControllerCompletionHandler completionHandler = ^(TWTweetComposeViewControllerResult result)
{
[self dismissModalViewControllerAnimated:YES];
NSString *info;
if(result == TWTweetComposeViewControllerResultDone)
{
info = [NSString stringWithFormat:#"Saved"];
ProgressIndicator *indicator = [[ProgressIndicator alloc]init];
[indicator tweetSuccessOrFail:info view:viewOnWhichToShow];
[indicator release];
indicator = nil;
}
else if(result == TWTweetComposeViewControllerResultCancelled)
{
// statements if tweet sheet cancelled.
}
[_tweetSheet release];
_tweetSheet = nil;
};
[_tweetSheet setCompletionHandler:completionHandler];
}
#pragma mark -
#pragma mark Share to Twitter
-(void)share:(UIImage*)imageToUpload viewOnWhichToShow:(UIView *)viewOnWhichToShow
{
[self setView:viewOnWhichToShow];
[self buildTweetSheet:viewOnWhichToShow];

Making the iPhone vibrate
I have two buttons. One button adds up, one button adds down. The question is when I certain number such as lets say 22 is in the text area, the phone vibrates for a certain mount of time. Here is my code for it:
What I am trying to say is IF Label Displays "22" THEN VIBRATE PHONE... The question is how do i go about writing this.. I'm still learning so any help regarding this would be much appreciated! Here is my code so far:
#import "StartCountViewController.h"
#import "AudioToolbox/AudioServices.h"
#implementation StartCountViewController
int Count=0;
-(void)awakeFromNib {
startCount.text = #"0";
}
- (IBAction)addNumber {
if(Count >= 999) return;
NSString *numValue = [[NSString alloc] initWithFormat:#"%d", Count++];
startCount.text = numValue;
[numValue release];
}
- (IBAction)vibrate {
}
- (IBAction)subtractNumber {
if(Count <= -35) return;
NSString *numValue = [[NSString alloc] initWithFormat:#"%d", Count--];
startCount.text = numValue;
[numValue release];
}
- (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.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
#end
This is basically a duplicate of Programmatically make the iPhone vibrate
Having said that, I think your code is still going to have errors, and the syntax seems deprecated.
Here's an example. I didn't try this on an actual iphone which would be required to test the vibration, but it should work provided you add the AudioToolbox framework to your project, and of course your XIB file has the necessary connections:
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
#property (retain, nonatomic) IBOutlet UILabel *numberLabel;
- (IBAction)addNumber:(id)sender;
- (IBAction)subtractNumber:(id)sender;
#end
ViewController.m
#import "ViewController.h"
#import "AudioToolbox/AudioServices.h"
#interface ViewController ()
{
int count;
}
#end
#implementation ViewController
#synthesize numberLabel;
- (void)viewDidLoad
{
count = 0;
[self updateCount];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[self setNumberLabel:nil];
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
- (void)dealloc
{
[numberLabel release];
[super dealloc];
}
- (IBAction)addNumber:(id)sender
{
if(count >= 999) {
return [self vibrate];
}; // ignore numbers larger than 999
count++;
[self updateCount];
}
- (IBAction)subtractNumber:(id)sender
{
if(count <= -35) {
return [self vibrate];
}; // ignore numbers less than -35
count--;
[self updateCount];
}
-(void)updateCount
{
NSString *countStr = [[NSString alloc] initWithFormat:#"%d",count];
[self.numberLabel setText:countStr];
[countStr release];
}
-(void)vibrate
{
NSLog(#"I'm vibrating");
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
#end

Are you sure your leaderboard category id is correct?
Do you get any error messages in your request blocks?
If you get no response to your asynchronous request blocks, it means gamecenter is not ready to handle your request. You need to wait for a few hours if you just created the leaderboard.
I have followed many tutorials and my links in my web view are still not opening up in safari.
I am a noob, this is my first IPhone App, so I hope I'm just missing something simple.

And here is my Header File

Does the shouldStartLoadWithRequest method fire? It may be that you haven't connected the delegate in your nib file. Usually this will be connected to your view controller, or whatever file the shouldStartLoadWithRequest method is found in.
Hi i am designing a basic iPhone/iPad app that has a UINavigationController. The user clicks on the table row and it opens up a video in full screen. This works well and plays the video. however when you click on the navigation bar to go back to the table on the rootViewController the video keeps playing the audio in the background. Any ideas?

Apple explains that video playback may be set to use "your application’s audio session by default, but can be configured to use a system-supplied audio session."
If you check the audio documentation, you will find you can setup behavior to stop or keep playing music if application goes to background (typically, to obtain the iPod player behavior). That's where you should set the proper application variable.
I'm implementing Mobclix in my app, and when following the instructions, it tells us to properly release and dealloc the adview. It also tells us that when the view appears, you should call refreshAds and when it disappears you should pause refresh ads:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.adView resumeAdAutoRefresh];
}

- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.adView pauseAdAutoRefresh];
}
#implementation RootViewController
- (void)viewDidUnload {
[self.adView cancelAd];
self.adView.delegate = nil;
self.adView = nil;
}
- (void)dealloc {
[self.adView cancelAd];
self.adView.delegate = nil;
self.adView = nil;
[super dealloc];
}
#end
My question is that I have a lot of view controllers, so it would be inconvenient to implement these things on each view. Is there anyway I can call these methods in one place and have it work for all views?
What you can do is subclass UIViewController and have all your viewControllers to inherit these things.
So basically you could have AdsViewController.h wich will look like
#import <Foundation/Foundation.h?
#interface AdsViewController: UIViewController {
}
#property (nonatomic, retain) <#AdsViewType#> *adsView;
#end
and your AdsViewController.m will have to look pretty much like this
#import "AdsViewController.h"
#implementation AdsViewController
#synthesize adsView = _adsView;
- (id)init {
self = [super init];
if (self) {
_adsView = [[<#AdsViewType#> alloc] init];
_adsView.delegate = self;
}
return self;
}
- (void)viewDidUnload {
[self.adView cancelAd];
self.adView = nil;
[super viewDidUnload];
}
- (void)dealloc {
[self.adView cancelAd];
self.adsView = nil;
[super dealloc];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.adView resumeAdAutoRefresh];
}

- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.adView pauseAdAutoRefresh];
}
#end
After this have all your viewControllers to subclass this instead of UIViewController. Hope this helps.
