i just solved using a new class #import <UIKit/UIKit.h> @interface ZoomScrollViewController : UIViewController <UIScrollViewDelegate> @property (nonatomic, strong) UIScrollView *zoomScrollView; @end #import "ZoomScrollViewController.h" #import <sys/utsname.h> @implementation ZoomScrollViewController - (void)viewDidLoad { [super viewDidLoad]; // Disabilita gli inset automatici su iOS 11+ if (@available(iOS 11.0, *)) { self.zoomScrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever; } else { self.automaticallyAdjustsScrollViewInsets = NO; } // Se stai usando Interface Builder, collega la scrollView via outlet. // Altrimenti: UIView *orig = self.view; UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:orig.frame]; scroll.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; scroll.delegate = self; scroll.backgroundColor = [UIColor blackColor]; self.zoomScrollView = scroll; [scroll addSubview:orig]; self.view = scroll; // Assicurati che lo scrollView non si veda “bianco” dove non c'è contenuto self.zoomScrollView.backgroundColor = self.view.backgroundColor; // Disabilita inset automatici su iOS 11+ if (@available(iOS 11.0, *)) { self.zoomScrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever; } else { self.automaticallyAdjustsScrollViewInsets = NO; } } // Helper per recuperare l’identificativo del device - (NSString*)deviceModelIdentifier { struct utsname systemInfo; uname(&systemInfo); return [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; } - (void)viewDidLayoutSubviews { [super viewDidLayoutSubviews]; UIView *content = self.zoomScrollView.subviews.firstObject; if (!content) return; // 1) Reset content.transform = CGAffineTransformIdentity; content.frame = CGRectMake(0, 0, 1024, 768); // 2) Dimensioni container CGSize cSize = self.zoomScrollView.bounds.size; CGFloat scaleX = cSize.width / 1024.0; CGFloat scaleY = cSize.height / 768.0; // 3) Controllo dispositivo NSString *modelID = [self deviceModelIdentifier]; NSLog(@"🔖 Device model: %@", modelID); NSLog(@"scaleX: %.3f, scaleY: %.3f", scaleX, scaleY); BOOL isiPadMiniOrA16 = NO; if ([modelID hasPrefix:@"iPad14,1"] || [modelID hasPrefix:@"iPad14,2"] || [modelID hasPrefix:@"iPad14,6"] || [modelID hasPrefix:@"iPad14,7"] || [modelID hasPrefix:@"iPad15,7"]) { isiPadMiniOrA16 = YES; } if (isiPadMiniOrA16) { scaleX = 1.152; // puoi mantenere scaleY come calcolato sopra, oppure settarlo fisso se necessario } NSLog(@"scaleX: %.3f, scaleY: %.3f", scaleX, scaleY); // 4) Applica trasformazione (stretch X) content.transform = CGAffineTransformMakeScale(scaleX, scaleY); // 4b) Centra il contenuto trasformato nella scrollView CGSize scaledSize = CGSizeMake(1024 * scaleX, 768 * scaleY); self.zoomScrollView.contentSize = scaledSize; CGFloat offsetX = (self.zoomScrollView.bounds.size.width - scaledSize.width) / 2.0; CGFloat offsetY = (self.zoomScrollView.bounds.size.height - scaledSize.height) / 2.0; // Assicura che gli offset siano >= 0 offsetX = MAX(0, offsetX); offsetY = MAX(0, offsetY); // Posiziona il contenuto al centro content.center = CGPointMake(scaledSize.width / 2.0 + offsetX, scaledSize.height / 2.0 + offsetY); // 5) Calcola nuova size del contenuto trasformato self.zoomScrollView.contentSize = scaledSize; // 6) Centra orizzontalmente solo se necessario CGFloat xOff = (scaledSize.width - cSize.width) / 2.0; [self.zoomScrollView setContentOffset:CGPointMake(xOff, 0) animated:NO]; // 7) Disattiva lo zoom dinamico della scrollView self.zoomScrollView.minimumZoomScale = 1.0; self.zoomScrollView.maximumZoomScale = 1.0; self.zoomScrollView.zoomScale = 1.0; } @end code-block with this tricks works in ios18.5 and 26

i found a UIDesignRequiresCompatibility for plist, but i don't understand if is temporary until beta or will works in the future

i have the same issue... my application have over 600 views objc + xib what the way for adapt the app fullscreen? we cannot rewrite all views

using a function for autoresizing works... in the future what do you suggest me? using swift and objc both, rewritter is too big project -(void)fixAutoResizingForSubviews:(UIView *)parent { // 19/06/2025 Simone per ios26 for (UIView *sub in parent.subviews) { if (sub == barMenu) { sub.autoresizingMask = UIViewAutoresizingFlexibleWidth; // No flexibleHeight } else { sub.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; } [self fixAutoResizingForSubviews:sub]; } }

i try to update using autolayout but another issue is the new 3 buttons (close, hide and fullscreen) are over the uibutton inside ma left bar, is it possible create a margin when are showed?

sorry, i just attached sample... this project was born in 2013 with objc and xib, at the moment is over 300 views and use xib with a scaled zoom for adapt to screen size like: CGFloat scale=[[UIScreen mainScreen] scale]; CGRect screenBounds = [[UIScreen mainScreen] bounds]; CGSize screenSize = CGSizeMake(screenBounds.size.width*scale,screenBounds.size.height*scale); // 2048 e 1536 sono le risoluzioni del retina CGFloat scalaX=screenSize.width/2048; CGFloat scalaY=screenSize.height/1536; if ((screenSize.width==1366) && (screenSize.height==1024)) { scalaX=1.34; scalaY=1.34; } if (scalaX<1) { scalaX=1; } if ((scalaY<1) && (!((screenBounds.size.width*scale==2266) && (screenBounds.size.height*scale==1488)))) { scalaY=1; } CGAffineTransform transform = CGAffineTransformMakeScale(scalaX,scalaY); self.view.transform = transform; code-block

solved with 17.7.8 today

mee too, any solutions for ipad 6th gen?

any ideas for can use webpush notification inside webpage like pwa?

with ios17.4 will be works fcm firebase webpush notification?

i found a possible solution: https://github.com/sumup/sumup-ios-sdk/issues/133 my issue will be solve removing sumup sdk (that i use inside a project)

i try to create programmatically but the error is the same: UIDatePicker *datePicker = [[UIDatePicker alloc] init]; datePicker.datePickerMode = UIDatePickerModeDateAndTime; if (@available(iOS 13.4, *)) { [datePicker setPreferredDatePickerStyle:UIDatePickerStyleWheels]; } else { // Fallback on earlier versions } datePicker.date = [NSDate date]; [self.view addSubview:datePicker]; datePicker.frame = CGRectMake(0, 0, self.view.frame.size.width, 216); // Puoi personalizzare queste dimensioni a tuo piacimento if (@available(iOS 15.0, *)) { datePicker.roundsToMinuteInterval=NO; } else { // Fallback on earlier versions } if i put datePicker.datePickerMode = UIDatePickerModeDate; works... the issue is when contant is time

the project is objectc project create on 2013, during the years will be updates but have over 200 views in xib mode, everything works but uipicker crash... is uikit project

the problem is that if i simply put a datapicker inside a new project works... if i put datepicker in a form already present (on xib) and i set time wheel, when i scroll the time crash, but in the class there isn't any event of datepicker, only scroll crash (inside the apple library).. the same with ios 17.0 works

try also with ios17.2 but crash always Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]' *** First throw call stack: ( 0 CoreFoundation 0x00007ff80049aa09 __exceptionPreprocess + 242 1 libobjc.A.dylib 0x00007ff8000638b4 objc_exception_throw + 48 2 CoreFoundation 0x00007ff800508c8d -[__NSPlaceholderDictionary initWithObjects:forKeys:count:] + 604 3 CoreFoundation 0x00007ff800499200 +[NSDictionary dictionaryWithObjects:forKeys:count:] + 49 4 UIKitCore 0x00007ff804ce4703 __59-[_UIDatePickerCalendarTimeLabel attributedTextWithRanges:]_block_invoke.150 + 156 5 UIKitCore 0x00007ff804ce3fd0 -[_UIDatePickerCalendarTimeLabel applyTextAttributesForState:inputScope:updater:] + 404 6 UIKitCore 0x00007ff804ce432f -[_UIDatePickerCalendarT *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]' *** First throw call stack: ( 0 CoreFoundation 0x00007ff80049aa09 __exceptionPreprocess + 242 1 libobjc.A.dylib 0x00007ff8000638b4 objc_exception_throw + 48 2 CoreFoundation 0x00007ff800508c8d -[__NSPlaceholderDictionary initWithObjects:forKeys:count:] + 604 3 CoreFoundation 0x00007ff800499200 +[NSDictionary dictionaryWithObjects:forKeys:count:] + 49 4 UIKitCore 0x00007ff804ce4703 __59-[_UIDatePickerCalendarTimeLabel attributedTextWithRanges:]_block_invoke.150 + 156 5 UIKitCore 0x00007ff804ce3fd0 -[_UIDatePickerCalendarTimeLabel applyTextAttributesForState:inputScope:updater:] + 404 6 UIKitCore 0x00007ff804ce432f -[_UIDatePickerCalendarTimeLabel attributedTextWithRanges:] + 667 7 UIKitCore 0x00007ff805ef44c6 -[_UIDatePickerWheelsTimeLabel pushCurrentStateIntoUI] + 77 8 UIKitCore 0x00007ff804ce4e3a -[_UIDatePickerCalendarTimeLabel stateMachineUpdateFromState:toState:] + 148 9 UIKitCore 0x00007ff805ef4c5c -[_UIDatePickerWheelsTimeLabel stateMachineUpdateFromState:toState:] + 47 10 UIKitCore 0x00007ff804ce3675 __68-[_UIDatePickerCalendarTimeLabel initWithTimeFormat:minuteInterval:]_block_invoke + 50 11 UIKitCore 0x00007ff805c61524 handleEvent + 298 12 UIKitCore 0x00007ff804ce4d8f -[_UIDatePickerCalendarTimeLabel _stateMachineSendEvent:] + 110 13 UIKitCore 0x00007ff805ef4cac -[_UIDatePickerWheelsTimeLabel beginEditingWheels] + 42 14 UIKitCore 0x00007ff805b53f64 -[_UIDatePickerView pickerTableView:didChangeSelectionBarRowFrom:to:] + 704 15 UIKitCore 0x00007ff805b5aa4c -[UIPickerColumnView pickerTableView:didChangeSelectionBarRowFrom:to:] + 171 16 UIKitCore 0x00007ff805b5ee1a -[UIPickerTableView _setSelectionBarRow:] + 223 17 UIKitCore 0x00007ff805b5e5a3 -[UIPickerTableView _setContentOffset:notify:] + 583 18 UIKitCore 0x00007ff8061ce25c -[UIScrollView _updatePanGesture] + 5091 19 UIKitCore 0x00007ff80551c3f9 -[UIGestureRecognizerTarget _sendActionWithGestureRecognizer:] + 71 20 UIKitCore 0x00007ff8055260a3 _UIGestureRecognizerSendTargetActions + 100 21 UIKitCore 0x00007ff805522dfb _UIGestureRecognizerSendActions + 303 22 UIKitCore 0x00007ff8055221a8 -[UIGestureRecognizer _updateGestureForActiveEvents] + 685 23 UIKitCore 0x00007ff80550f80d _UIGestureEnvironmentUpdate + 3935 24 UIKitCore 0x00007ff80550e449 -[UIGestureEnvironment _updateForEvent:window:] + 892 25 UIKitCore 0x00007ff805becceb -[UIWindow sendEvent:] + 5262 26 UIKitCore 0x00007ff805bc1cfc -[UIApplication sendEvent:] + 772 27 UIKitCore 0x00007ff805c700ef __dispatchPreprocessedEventFromEventQueue + 8406 28 UIKitCore 0x00007ff805c729ac __processEventQueue + 8415 29 UIKitCore 0x00007ff805c685f6 __eventFetcherSourceCallback + 163 30 CoreFoundation 0x00007ff8003f7487 CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION + 17 31 CoreFoundation 0x00007ff8003f73c9 __CFRunLoopDoSource0 + 157 32 CoreFoundation 0x00007ff8003f6bc6 __CFRunLoopDoSources0 + 215 33 CoreFoundation 0x00007ff8003f12fb __CFRunLoopRun + 919 34 CoreFoundation 0x00007ff8003f0b81 CFRunLoopRunSpecific + 557 35 GraphicsServices 0x00007ff8103b808f GSEventRunModal + 137 36 UIKitCore 0x00007ff805ba1229 -[UIApplication _run] + 972 37 UIKitCore 0x00007ff805ba5c97 UIApplicationMain + 123 38 simulatore 0x0000000108b5b488 main + 104 39 dyld 0x000000010a1023e0 start_sim + 10 40 ??? 0x000000010d3d83a6 0x0 + 4517102502 ) libc++abi: terminating due to uncaught exception of type NSException
