How can i display the UIimagepickerController at the middle of the screen - iphone

I am developing one application.In that I am using the UIImagePickerController.That one will be opened total screen.But i need to open that picker at the middle of the screen(50,50,220,380).So please tell mw how can i do this one.

I ended up with a lovely miniature camera imagePicker floating in the middle of my screen using the following
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
// imagePickerController.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
// imagePickerController.cameraCaptureMode = UIImagePickerControllerSourceTypePhotoLibrary;
UIView *controllerView = imagePickerController.view;
controllerView.alpha = 0.0;
controllerView.transform = CGAffineTransformMakeScale(0.5, 0.5);
[[[[UIApplication sharedApplication] delegate] window] addSubview:controllerView];
[UIView animateWithDuration:0.3
delay:0.0
options:UIViewAnimationOptionCurveLinear
animations:^{
controllerView.alpha = 1.0;
}
completion:nil
];

Rectangle bringing on camera in ZBar scanner?

How can we bring rectangle on camera for barcode scanning like red laser with scanningound? is there any built in property?I tried following:
reader.readerView.tracksSymbols = YES;
reader.readerView.trackingColor = [UIColor redColor];
[reader setShowsZBarControls:NO];
reader.readerView.tracksSymbols = TRUE;
scanner.accessibilityFrame = CGRectMake(100, 100, 200, 300);
Add the rectange as an overlay on your camera view.Here is the code:
- (IBAction) scanButtonTapped
{
// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;
ZBarImageScanner *scanner = reader.scanner;
reader.showsZBarControls = NO;
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 0];
// present and release the controller
[self presentModalViewController: reader
animated: YES];
reader.cameraOverlayView = [self CommomOverlay];
[reader release];
}
-(UIView*)CommomOverlay{
UIView* view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,480)];
UIImageView *FrameImg = [[UIImageView alloc] initWithFrame:CGRectMake(70,160,203,180)];
[FrameImg setImage:[UIImage imageNamed:#"overlaygraphic.png"]];
[view addSubview:FrameImg];
return view;
}
hope this will help you..:)
Did you try
reader.cameraOverlayView = overLayView;
?? i.e cameraOverlayView property of UIImagePickerController.
There you can set what ever you want. Hope this is what you want.

Show camera on only half of the screen

I'd like to display the camera view on only half the screen on both iPhone and iPad. I've done a lot of searching, but haven't found a solution.
try with this .. if this is not help full for you or facing any problem, tell me i will provide you some other sample code ..
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
UIView *controllerView = imagePickerController.view;
controllerView.alpha = 0.0;
controllerView.transform = CGAffineTransformMakeScale(0.5, 0.5);
[[[[UIApplication sharedApplication] delegate] window] addSubview:controllerView];
[UIView animateWithDuration:0.3
delay:0.0
options:UIViewAnimationOptionCurveLinear
animations:^{
controllerView.alpha = 1.0;
}
completion:nil
];
[imagePickerController release];

UISplitView with SingleViewController

How do I add UISplitView after clicking on the SingleView application? Clearly when the user has successfully logged in then they will see splitView? How is it possible? Please give me guidelines or if possible then code for that because I'm new to iPhone development and I haven't more knowledge for it?
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration: 1.90];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.navigationController.view cache:YES];
MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:#"MasterViewController" bundle:nil];
if (!masternavigationController) {
masternavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
}
DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:nil];
if (!splitViewController) {
splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:masternavigationController, detailViewController, nil];
UIViewController *view_controller = (UIViewController *)[navigationController.viewControllers objectAtIndex:([navigationController.viewControllers count]-1)];
[masternavigationController.navigationBar setHidden:TRUE];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO];
[splitViewController.view setBounds:CGRectMake(0, 0, 1024, 748)];
[splitViewController.view setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
[view_controller.view setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
view_controller.view.tag = 17;
[UIView animateWithDuration:1.05 animations:^{navigationController.view.alpha = 0.0;} completion:^(BOOL finished){
[navigationController.view addSubview:splitViewController.view];
[UIView animateWithDuration:1.00 animations:^{navigationController.view.alpha = 1.0;} completion:nil];}];
rootview *rtview = [[rootview alloc] initWithNibName:#"rootview" bundle:nil];
rtview.delegate = detailViewController;
[detailViewController.view addSubview:rtview.view];
flag = YES;
[rtview release];
}
[UIView commitAnimations];
// [NSTimer scheduledTimerWithTimeInterval:0.3 target:self selector:#selector(doneAnimation) userInfo:nil repeats:NO];
[masterViewController release];
[detailViewController release];
This is how we have to add splitview controler you have to check the condition weather you are logged in or not and then call this in a method

UIImagePickerController using addSubView leaves white margin at the top of view

I need to add UIImagePickerController in camera mode using addSubView. I have written code for it but it leaves white space at the top of the view.
-(void)viewDidAppear:(BOOL)animated{
NSLog(#"ViewDidAppear");
OverlayView *overlay = [[OverlayView alloc]
initWithFrame:CGRectMake(0,0,SCREEN_WIDTH,SCREEN_HEIGTH)];
//create a new image picker instance
picker = [[UIImagePickerController alloc]init];
self.picker.delegate = self;
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
//set source to video!
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
//hide all controls
picker.showsCameraControls = NO;
picker.navigationBarHidden = NO;
picker.toolbarHidden = YES;
picker.editing = NO;
//make the video preview full size
picker.wantsFullScreenLayout = YES;
slider.value = 1;
picker.cameraViewTransform = CGAffineTransformScale(picker.cameraViewTransform,slider.value, slider.value);
//set our custom overlay view
picker.cameraOverlayView = overlay;
[picker.view addSubview:slider];
//show picker
[picker.view addSubview:capture];
[picker.view addSubview:library];
//[picker.view addSubview:multicapture];
[capture addTarget:self action:#selector(takepicture) forControlEvents:UIControlEventTouchUpInside];
[library addTarget:self action:#selector(goToLibrary) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:picker.view];
[picker viewWillAppear:YES];
[picker viewDidAppear:YES];
}else{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Test Text" message:#"Camera is Not Availble" delegate:self cancelButtonTitle:#"ok" otherButtonTitles:nil];
[alert show];
[alert release];
}
[overlay release];
}
Can anyone please help me.
Thanks.
As kante0 says, that white margin is the status bar disappeared. If you want to show the status bar, use kante0's solution:
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
[self.view addSubview:picker.view];
If you don't want to show the status bar (typically when you show the camera preview), use this piece of code:
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
[self.view setFrame: [[UIScreen mainScreen] bounds]];
// Place your overlay view here
[self.view addSubview:picker.view];
But you have to remember that when the pickerview is removed, if you want to show again the status bar, you'll need to do this:
[picker.view removeFromSuperview];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
[self.view setFrame: [[UIScreen mainScreen] applicationFrame]];
// If you need to place elements programmatically, do it here
Look into NSScreen for getting accurate dimensions. Double check that you have the height value correct. For example, you could do this:
int width = [[NSScreen mainScreen] frame].size.width;
int height = [[NSScreen mainScreen] frame].size.height;
Is not a white margin, is status bar disappearing.
I solved the problem with:
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];

Iphone web view during use of Camera

Is it possible to open webview during use of camera in app.if it is possible plz let me know.
You could try:
- (BOOL)startCameraPickerFromViewController:(UIViewController*)controller usingDelegate:(id<UIImagePickerControllerDelegate>)delegateObject
{
//NSLog(#"008 ::Create Postcard :: start photo camera");
if ((![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) || (delegateObject == nil) || (controller == nil)) {
return NO;
}
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
UIView *overlay = [[UIView alloc]initWithFrame:CGRectMake(x, y, w, h)];
// overlay.transform = CGAffineTransformMakeRotation(M_PI / 2.0);
// overlay.backgroundColor = [UIColor redColor];
{create your webview here}
[overlay addSubview:webview];
[webview release];
[picker.cameraOverlayView = overlay;
[controller presentModalViewController:picker animated:YES];
return YES;
}
If you have enough recources on the phone it might could work i guess
