How can I fix the "UIPopoverController is deprecated" warning?
(4 answers)
Closed 6 years ago.
I have developed a project that shows error :
'UIPopoverController' is deprecated: first deprecated in iOS 9.0 - UIPopoverController is deprecated. Popovers are now implemented as UIViewController presentations. Use a modal presentation style of UIModalPresentationPopover and UIPopoverPresentationController.
My codings are:
ViewController.h:
#import <UIKit/UIKit.h>
#import <Photos/Photos.h>
#import <MobileCoreServices/MobileCoreServices.h>
#interface ViewController : UIViewController
<UIImagePickerControllerDelegate, UINavigationControllerDelegate>
- (IBAction)touch:(id)sender;
#end
#interface SecondView : UIViewController
<UIImagePickerControllerDelegate, UINavigationControllerDelegate>
//video gallery
#property (strong,nonatomic) UIPopoverPresentationController *popOver;
#property (weak, nonatomic) IBOutlet UIView *studentView;
#property (strong, nonatomic) NSURL *videoURL;
#end
ViewController.m:
- (void)openGallery {
UIImagePickerController *Picker=[[UIImagePickerController alloc] init];
Picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
Picker.mediaTypes=[[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
Picker.delegate=self;
if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
UIPopoverController *popController=[[UIPopoverController alloc] initWithContentViewController:Picker];
[popController presentPopoverFromRect:CGRectMake(0, 600, 160, 300) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popOver=popController;
}
else
{
[self presentViewController:Picker animated:YES completion:nil];
}
}
#pragma mark - UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
if (self.studentView) {
self.videoURL = info[UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion:NULL];
[[NSUserDefaults standardUserDefaults] setObject:[self.videoURL absoluteString] forKey:#"url1"];
}
}
I could not proper reference for UiModalPresentationPopover. Can someone help me to solve this error. Any help is much appreciated. Thank you.
use UIModalPresentationPopover
In a horizontally regular environment, a
presentation style where the content is displayed in a popover view.
The background content is dimmed and taps outside the popover cause
the popover to be dismissed. If you do not want taps to dismiss the
popover, you can assign one or more views to the passthroughViews
property of the associated UIPopoverPresentationController object,
which you can get from the popoverPresentationController property.
In a horizontally compact environment, this option behaves the same as
UIModalPresentationFullScreen.
Available in iOS 8.0 and later.
Reference UIModalPresentationStyle Reference
for example
ModalViewController *modal = [[ModalViewController alloc] init];
modal.modalPresentationStyle = UIModalPresentationPopover;
modal.transitioningDelegate = self;
modal.popoverPresentationController.sourceView = self.view;
modal.popoverPresentationController.sourceRect = CGRectZero;
modal.popoverPresentationController.delegate = self;
[self presentViewController:modal animated:YES completion:nil];
else use UIPopoverPresentationController
for example
UIPopoverPresentationController *popController = [self. popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionAny;
popController.barButtonItem = self.leftButton;
popController.delegate = self;

I am seeing memory leaks in UIDatePicker when used in a popover on an iPad running IOS 8.3. I'm getting approx 5K in multiple memory leaks every time the date picker is popped up and then dismissed. The leaked object is NSDateComponents, and the responsible frame is [_UIDatePickerMode _yearlessYearForMonth:].
I have written a simple test app to demonstrate the problem (https://github.com/david-ape/datepickertest/). I've included both a UIPopoverController option and a UIPopoverPresentationController option, but it doesn't seem to matter which is used.
Am I doing something wrong, or is there a workaround, or do I need to wait for a fix from Apple? If the latter, then can anyone suggest a third party control that I could use in place of UIDatePicker?
Below is the code I'm using to pop up the date pickers.
Header file
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController <UIPopoverControllerDelegate,
UIPopoverPresentationControllerDelegate>
#end
Implementation file
#import "ViewController.h"
#interface ViewController ()
#property (nonatomic, strong) UIPopoverController *ios7Popover;

+ (UIViewController *)buildDatePickerViewController
{
CGRect frame = CGRectMake(0, 0, 350, 216);
UIViewController *viewController = [[UIViewController alloc]init];
viewController.preferredContentSize = frame.size;
UIDatePicker *datepicker = [[UIDatePicker alloc]initWithFrame:frame];
datepicker.datePickerMode = UIDatePickerModeDate;
datepicker.hidden = NO;
datepicker.date = [NSDate date];
[viewController.view addSubview:datepicker];
return viewController;
}
// popup date picker using UIPopoverController (IOS7 compatible)
- (IBAction)datePickerPopupIOS7:(UIButton *)sender
{
UIViewController *viewController = [ViewController buildDatePickerViewController];
self.ios7Popover = [[UIPopoverController alloc]initWithContentViewController:viewController];
self.ios7Popover.delegate = self;
[self.ios7Popover presentPopoverFromRect:sender.frame
inView:self.view
permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown| UIPopoverArrowDirectionLeft|UIPopoverArrowDirectionRight)
animated:YES];
}
// popup date picker using UIPopoverPresentationController (IOS8 or later required)
// Thanks to http://stackoverflow.com/a/26944036/1764243 for how to do this
- (IBAction)datePickerPopupIOS8:(UIButton *)sender
{
if ([UIPopoverPresentationController class])
{
UIViewController *viewController = [ViewController buildDatePickerViewController];
UINavigationController *destNav = [[UINavigationController alloc] initWithRootViewController:viewController];
destNav.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = destNav.popoverPresentationController;
popover.delegate = self;
popover.sourceView = self.view;
popover.sourceRect = [sender frame];
destNav.navigationBarHidden = YES;
[self presentViewController:destNav animated:YES completion:nil];
}

I got this error in using iPad. But iPhone is worked. Please share the solution. My code is given below.
-(void)pickImageFromLibrary
{
UIImagePickerController *picker10 = [[UIImagePickerController alloc] init];
picker10.delegate = self;
picker10.allowsEditing = YES;
picker10.view.tag=100;
picker10.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker10 animated:YES completion:NULL];
}
you should try this code!
[self.presentedViewController dismissViewControllerAnimated:NO completion:nil];
UIImagePickerCopntroller must be presented in popover in iPad. take a look at the following code for iPad:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:self.selectedImageView.bounds inView:self.selectedImageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popOver = popover;
} else {
[self presentModalViewController:picker animated:YES];
}
don't forget to add a strong property for the popover:
#property (nonatomic, strong) UIPopoverController *popOver;
here are the delegate methods for dismissing it:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
here is the link to the class reference for more info: Class Refference
I have a UIButton and when the user clicks it, I want to start the image picker controller
I already configure what I think it is enough but I couldn't know what is the message that I have to pass to that image picker to start working
This is my code
#import "ImagePickerViewController.h"
#interface ImagePickerViewController ()
#property (weak, nonatomic) IBOutlet UIImageView *image;
#end
#implementation ImagePickerViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (IBAction)SelectImage:(id)sender {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
#end
I have already set the correct protocols:
#interface ImagePickerViewController : UIViewController < UINavigationControllerDelegate,UIImagePickerControllerDelegate>
#end
You need to present the UIImagePicker
- (IBAction)SelectImage:(id)sender
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:NO completion:nil];
}
You can show the picker with:
[self presentViewController:imagePicker animated:YES completion:NULL];
And then in your delegate callback imagePickerController:didFinishPickingMediaWithInfo you get the image and dismiss the picker again:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image = info[UIImagePickerControllerEditedImage];
[picker dismissViewControllerAnimated:YES completion:NULL];
}
You have to tell your view controller class to show the UIImagePickerController.
Simply use
[self presentViewController:imagePicker animated:YES completion:nil];
This will present it modally. If you are running on an iPad, you instead have to present it in a popover controller, as follows:
Declare a new property in the #interface:
#property (nonatomic, strong) UIPopoverController* imagePickerPopover;
Present the popover controller e.g:
UIButton* button = sender;
self.imagePickerPopover = [[UIPopoverController alloc] initWithContentViewController:self.imagePicker];
[self.imagePickerPopover presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
I have replaced the nave bar in my iOS7 app in Xcode 5 using the following code (also removed the status bar if that matters):
AppDelegate.M
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"navBar"] forBarMetrics:UIBarMetricsDefault];
In one of my image view controllers I am using a UIImagePicker to pick a profile pic. The problem is when it goes to the photo gallery it uses the main "navBar" image which hides some controls and basically stacks 2 of the same nav bars on top. Can I have a different nav bar for the photogallery? Here is the View controllers:
FirstView.H
#import <UIKit/UIKit.h>
#interface IBFirstViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
#property (weak, nonatomic) IBOutlet UILabel *userName;
#property (weak, nonatomic) IBOutlet UILabel *userEmail;
#property (weak, nonatomic) IBOutlet UIImageView *backgroundImage;
- (IBAction)logout:(id)sender;
- (IBAction)edit:(id)sender;
#end
FirstView.M
- (IBAction)edit:(id)sender {
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:NO completion:Nil];
}
I have similar problem when using [UINavigationBar appearance] to custom navigation bar on iOS7. If we do that, all iOS native controller which is subclass of UINavigationController, is effected too, ex: UIImagePickerController, MFMessageComposeViewController...
If you want to use custom navigation style within your controllers, you have to apply with your UINavigationController instance instead of using [UINavigationBar appearance] singleton.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
UINavigationController *navigationController = (UINavigationController*)self.window.rootViewController;
[navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"navBar"] forBarMetrics:UIBarMetricsDefault];
...
}
Or in my case, I create subclass of UINavigationController
- (void)viewDidLoad
{
[super viewDidLoad];
[self setupAppearance];
...
}
- (void)setupAppearance
{
[self.navigationBar setBackgroundImage:[UIImage imageNamed:#"navBar"]
}
Then, when you create UIImagePickerController instance, just custom its navigation bar
- (IBAction)edit:(id)sender {
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.delegate = self;
// Custom another navigation style
[imagePickerController.navigationBar setBackgroundImage:[UIImage imageNamed:#"NEW-NAV-BAR-IMAGE"];
[self presentViewController:imagePickerController animated:NO completion:Nil];
}
Something strange is happening with my code.
Scenario: Open camera->Take picture->Pass the image taken to a viewcontroller(from a storyboard.
The thing is that my UIimage variable from the destination view is not available, not recognized!
My code
postviewController.h
#import <UIKit/UIKit.h>
#interface postAlertViewController : UIViewController
#property (nonatomic, retain) UIImage *cameraImage;
#end
postviewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
UIImageView *aImageview=[[UIImageView alloc]initWithFrame:CGRectMake(0, 60, self.view.frame.size.width,150 )];
aImageview.image=cameraImage;
[self.view addSubview:amageview];
}
Take picture and pass it to the view controller above
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:NULL];
ViewController *postView = [self.storyboard instantiateViewControllerWithIdentifier:#"postview"];
postView.cameraImage=(UIImage *)[info objectForKey:UIImagePickerControllerEditedImage];
[self.navigationController pushViewController:postView animated:YES];
}
The stroryboard ID is set to "postview".
What i am getting is:
Property 'cameraImage' not found on object of type 'ViewController *'
Why cameraImage is not available from the origin view although is declared in destination's .h file?
In another situation where i needed to pass a string between views, in same manner as above
[yourViewController setValue:mysc.title forKey:#"sendAlertTitle"];
worked ok.
Any help?
Thank you.
try this
postAlertViewController *postView = [self.storyboard instantiateViewControllerWithIdentifier:#"postview"];
and always use class and interface name start with capital
you can use this one for more ease.
- (IBAction)captureImage:(id)sender
{
if (! [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *deviceNotFoundAlert = [[UIAlertView alloc] initWithTitle:#"No Device" message:#"Camera is not available"
delegate:nil
cancelButtonTitle:#"Okay"
otherButtonTitles:nil];
[deviceNotFoundAlert show];
} else {
UIImagePickerController *cameraPicker = [[UIImagePickerController alloc] init];
cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
cameraPicker.delegate =self;
// Show image picker
[self presentViewController:cameraPicker animated:YES completion:nil];
}
}
-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
UIImage *selectedImage =[info objectForKey:UIImagePickerControllerOriginalImage];
ViewControllerName *Vc=[self.storyboard instantiateViewControllerWithIdentifier:#"captioEdit"];
Vc.postImgStr=[self scaleAndRotateImage:selectedImage];
[picker dismissViewControllerAnimated:YES completion:nil];
[self.navigationController pushViewController:captioViewEdit animated:YES];
}
//Delegate method of UIImagePickerController for image picker model cancel
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
Thanks
