I created an actionsheet that is called when a button on the navigation bar is pressed. It displays 3 buttons (send to email, print and cancel).
Now I don't know how to make the iPhone print the uiwebview when the "print" button in the actionsheet is pressed. Can anyone help me ? Or maybe has some sample code for me?
I am using the latest Xcode 4.3 with storyboard and programming for iphone.
Thanks in advance !
Use ActivitySheet instead...
UIImage *yourImage = [UIImage imageNamed:#"yourImage"]; //the image you want to print
NSArray *itemsToShare = #[yourImage];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil];
activityVC.excludedActivityTypes = #[ UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypeMail, UIActivityTypeMessage, UIActivityTypePostToFacebook, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo]; //or whichever you don't need >>> in this case we just have AirPrint
[self presentViewController:activityVC animated:YES completion:nil];

I am using UIActivityViewController in my new app for Facebook Share Option.
But if the user not login to the device, it dont working.. When select setting, Login page not appearing..
IActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityVC.excludedActivityTypes = #[UIActivityTypeAssignToContact, UIActivityTypePrint];
[self presentViewController:activityVC animated:TRUE completion:nil];
What can i do on this..? Is that the Problem of my code or a Common Error..?
iOS 6 introduced both the UIActivityViewController class and Social Framework, both of which may be used to integrate Twitter, Facebook and Sina Weibo functionality into iOS 6 applications. For general purpose requirements, the UIActivityViewController and SLComposeViewController classes provide an easy to implement path to social network integration.
UIActivityViewController *activityController =[[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
self presentViewController:activityController animated:YES completion:nil];
In order to use the SLComposeViewController class, a number of steps should be performed in sequence. Firstly, the application may optionally check to verify whether a message can be sent to the specified social network service. This essentially equates to checking if a valid social network account has been configured on the device and is achieved using the isAvailableForServiceType: class method, passing through as an argument the type of service required from the following options:
SLServiceTypeFacebook
SLServiceTypeTwitter
SLServiceTypeSinaWeibo
this is how you start ActivityIndicatorView with Loading lable
UIActivityIndicatorView *tempSpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
lable =[[UILabel alloc]init];
lable.center = self.view.center;
lable.text = #"Loading...";
lable.hidden=NO;
lable.backgroundColor = [UIColor clearColor];
lable.textColor = [UIColor blackColor];
[lable sizeToFit];
lable.center = CGPointMake(160, 255);
tempSpinner.center = self.view.center;
[self.view addSubview:tempSpinner];
[self.view addSubview:lable];
start where ever you want like this
[tempSpinner startAnimating];
stop it like this where ever you want
[tempSpinner stopAnimating];
hide unhide loading label as per requirement
Can I show this "Share Screen" in my own app using iOS 6? Somebody that knows how?
I'm afraid you are all wrong. I'm sorry for being this negative, but your wrong answers forced me to waste time in going for futile solutions.... instead you can use this code to achive this screen:
NSString* someText = self.textView.text;
NSArray* dataToShare = #[someText]; // ...or whatever pieces of data you want to share.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:^{}];
The code is from Social.framework.

I want my app to only use the front facing camera. So I've implemented the following code.
if ([UIImagePickerControllerisCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront]) {
self.imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;
}
This works the first time I open up the camera (it is using the front facing camera). But if I cancel the photo and then re-enter into the camera it is using the rear facing camera.
With each cancel / re-enter into camera it switches between front and rear cameras...
Is there something I am missing?
Tr this code .I used this code and it is working fine .Use this code either in button action or viewwillappear or viewdidload and dismiss the camera view properly
imgPicker =[[UIImagePickerController alloc] init];
imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imgPicker.cameraDevice=UIImagePickerControllerCameraDeviceFront;
imgPicker.showsCameraControls = YES;
imgPicker.allowsEditing = YES;
imgPicker.delegate=self;
[self presentViewController:imgPicker
animated:NO completion:nil];
I was having the same problem and resolved the issue in my case by including autorelease on the call to allocate the UIImagePickerController as shown here
UIImagePickerController *cameraUI = [[[UIImagePickerController alloc] init] autorelease];
I am using the following function to activate either the device camera or the image picker depending on the result of a UIActionSheet. if fromCamera=YES then it works on both iPhone and iPad. if fromCamera=NO then it works on iPhone and the image picker appears. But it crashes on the iPad with the following error: UIStatusBarStyleBlackTranslucent is not available on this device. I already know that the iPad can't display the UIStatusBarStyleBlackTranslucent statusBar, but how do I avoid this crash?
-(void)addPhotoFromCamera:(BOOL)fromCamera{
if(fromCamera){
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
else{
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentModalViewController:picker animated:YES];
}
If you set the picker to UIImagePickerControllerSourceTypePhotoLibrary on the iPad, then you must(!) present it in a popoverview, otherwise you get exceptions. I do it like this, to atleast control the size of the popover (the standard size is too small in my opinion):
-(void)openPhotoPicker
{
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.navigationBar.opaque = true;
//put the image picker in its own container controller, to control its size
UIViewController *containerController = [[UIViewController alloc] init];
containerController.contentSizeForViewInPopover = rightPane.frame.size;
[containerController.view addSubview:imagePicker.view];
//then, put the container controller in the popover
popover = [[UIPopoverController alloc] initWithContentViewController:containerController];
//Actually, I would like to do the following, but iOS doesn't let me:
//[rightPane addSubview:imagePicker.view];
//So, put the popover over my rightPane. You might want to change the parameters to suit your needs.
[popover presentPopoverFromRect:CGRectMake(0.0, 0.0, 10.0,0.0)
inView:rightPane
permittedArrowDirections:UIPopoverArrowDirectionLeft
animated:YES];
//There seems to be some nasty bug because of the added layer (the container controller), so you need to call this now and each time the view rotates (see below)
[imagePicker.view setFrame:containerController.view.frame];
}
I also have the following, to counter a rotation bug:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
if(imagePicker!=nil && rightPane.frame.size.width>0)
[imagePicker.view setFrame:imagePicker.view.superview.frame];
}
It ain't perfect, but it is ok for my testing purposes at the moment. I consider writing my own Imagepicker, because I don't like being forced to use the popoverview... but well, that's a different story.
I suspect the UIImagePicker is inheriting the translucent status bar from your Info.plist file or from the currently displayed view controller.
What happens if you make the app not have a translucent status bar?
I was having a similar issue, take a look at my answer here:

Can I programmatically turn on the camera flash on a new iPhone 4 device, before taking a picture with -takePicture?
I'm developing a photo taking app for iOS 4 and want to power on the flash light before the user takes a picture, so they can see the effect of the flash in advance.
The problem seems to be that for the flash light to stay on, you'll need to set the torchMode on and this is only possible in 'video mode' (UIImagePickerControllerCameraCaptureModeVideo), while you can only ask the UIImagePickerController to takePicture when it is on 'photo mode' (UIImagePickerControllerCameraCaptureModePhoto).
So, the following works, but only shows the flash light when taking a picture:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.mediaTypes = [NSArray arrayWithObjects:#"public.image", nil];
picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
[self presentModalViewController:picker animated:YES];
And this also works (shows the torch the whole time), but then I cannot take a picture.
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, nil];
picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
[self presentModalViewController:picker animated:YES];
When I try the toggleTorch code found here: Turn on torch/flash on iPhone there seems to not be any live video feed in the UIImagePickerController.
Are these UIImagePickerController and AVCaptureSession compatible with each other? or are you supposed to choose for either one or the other?
And does anybody know a workaround to get both the flash mode on (or torchMode) and to be able to takePicture?
Have a look at the WWDC 2010 sessions (specifically 409) where they go into functionality like the one you're looking for.
Essentially you need to move away from UIImagePickerController if you're looking to perform these custom camera functions and move towards AVFoundation classes.
