After upgrading to the 4.8.x SDK from 4.7.1 the DUXCameraSettingsController stopped displaying the actual settings panels, but continues to show the settings tab-bar, pressing the tabs does not make any settings appear. Is this a bug in the UXSDK or am I just using the controller wrong? I cannot find any example on the usage of that particular controller.
- (UIView *)view
{
UIView *view = [UIView new];
DUXCameraSettingsController *ctrl = [DUXCameraSettingsController cameraSettingsController];
ctrl.view.translatesAutoresizingMaskIntoConstraints = NO;
ctrl.view.frame = view.frame;
[view addSubview:ctrl.view];
[ctrl.view.topAnchor constraintEqualToAnchor:view.topAnchor].active = YES;
[ctrl.view.bottomAnchor constraintEqualToAnchor:view.bottomAnchor].active = YES;
[ctrl.view.leadingAnchor constraintEqualToAnchor:view.leadingAnchor].active = YES;
[ctrl.view.trailingAnchor constraintEqualToAnchor:view.trailingAnchor].active = YES;
[ctrl didMoveToParentViewController:nil];
return view;
}

So I had a full working solution in iOS7 that displays a LoginViewController via presentViewController in the AppDelegate's didFinishLaunching.
Basically I am doing something like this:
UIViewController *backgroundViewController = ...
self.window.rootViewController = backgroundViewController;
[self.window makeKeyAndVisible];
[self.window.rootViewController presentViewController:loginViewController
animated:NO ...]
In iOS8 I see a jump. First I see the backgroundViewController then after about 1 second or so the login appears.
So, how can I prevent this jump in iOS8?
I am seeing that are a ton of developers with this kind of problem but still didn't find a solution.
Also a hack (for now), but just one line of code
Add the view of the view controller you're presenting to the window before presentation
UIViewController *viewController = [[UIViewController alloc] init];
[viewController.view setBackgroundColor:[UIColor greenColor]];
// Temporary iOS8 fix for 'presentation lag' on launch
[self.window addSubview:viewController.view];
[self.window.rootViewController presentViewController:viewController animated:NO completion:nil];
If you are presenting a navigation controller than add the navigation controller's view instead of its top view controller.
I have a quick hacky fix:
//Make a screenshot of the ViewController first, or use a real image if you want
__block UIImageView *fakeImageView = [[UIImageView alloc] initWithImage:image];
fakeImageView.frame = vc.view.frame;
[self.view addSubview:fakeImageView];
[self presentViewController:vc animated:animated completion:^{
[fakeImageView removeFromSuperview];
fakeImageView = nil;
}];
It is not good for long term, but can quickly fix this issue without changing too much code.
Waiting for better solutions.
You can set the window to an instance of a temporary controller.
self.window.backgroundColor = [UIColor whiteColor]; //do some styling etc.
self.window.rootViewController = [LoginViewController new];
[self.window makeKeyAndVisible];
From the set controller (LoginViewController) you can push your real login controller with the desired transition. Once the login sequence is over you can make a transition from the login controller to the default application root view controller.
[UIView transitionWithView:[AppGlobal sharedApp].applicationWindow
duration:0.75
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[AppGlobal sharedApp].applicationWindow.rootViewController = [AppRootViewController new];
} completion:nil];
I have also faced the same problem in iOS8 and I found this solution:
ABCViewController *obj = [[ABCViewController alloc] initWithNibName:#"ABCViewController" bundle:nil];
CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromBottom;
transition.delegate = self;
[self.navigationControler.view.layer addAnimation:transition forKey:nil];
[appDelegate.navigationControler obj animated:NO];
obj = nil;
I hope this solution can help you!
This should work:
call [loginViewController view]
Before presenting it.
I have a UIViewController which contains a UICollectionView. On tapping any of the UICollectionViewCell I present a modal view controller.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
PopViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"DetailsView"];
vc.view.backgroundColor = [UIColor clearColor];
vc.transitioningDelegate = self;
vc.modalPresentationStyle = UIModalPresentationCustom;
[self presentViewController:vc animated:YES completion:nil];
The PopViewController shows up correctly. Now I want to restrict the device orientation when PopViewController is being presented. That is if PopViewController is presented in portrait mode then it should not change to landscape even if I switch to landscape mode (using Rotate Left or Right in simulator) until I dismiss the PopViewController.
I have used following code in PopViewController:
-(BOOL)shouldAutorotate {
return NO;
}
What else (or instead) is needed to lock the pop up view to the current orientation?
in your modal controller try to add this, also (iOS > 6)
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
to support iOS 5 or below you must additional add:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
I'm working with https://github.com/rsms/chromium-tabs in my project and I have created my app so the tabs are registered to a WebView. When I'm debugging I noticed that when I was viewing a Youtube video or any flash content and I switched tabs then switch back the content reloaded or the video restarted. Is there any reason this should hapen.
When a tab is selected it is set: [self becomeFirstResponder];
Other than that I have found no other connected way the flash would reset and the rest of the page would remain the same. I'm believing its a setting in WebView whenever it is not visible.
For the comment bellow:
I followed the examples on Github and used MyTabContents.mm to create the contents. Also used a custom webview.
MyTabContents.mm:
-(id)initWithBaseTabContents:(CTTabContents*)baseContents {
if (!(self = [super initWithBaseTabContents:baseContents])) return nil;
ProgressWebView *wv = [[ProgressWebView alloc] initWithFrame:NSZeroRect];
[wv setProgressDelegate:self];
[[wv mainFrame] loadRequest:[[NSURLRequest alloc] initWithURL:[NSURL URLWithString:#"https://google.com"]]];
[wv setShouldUpdateWhileOffscreen:YES];
webView = wv;
// Create a NSScrollView to which we add the NSTextView
NSScrollView *sv = [[NSScrollView alloc] initWithFrame:NSZeroRect];
[sv setDocumentView:wv];
[sv setHasVerticalScroller:NO];
// Set the NSScrollView as our view
self.view = sv;
return self;
}
AppDelegate.mm:
- (void)applicationDidFinishLaunching:(NSNotification *)notification {
CTBrowserWindowController* windowController =
[[CTBrowserWindowController alloc] initWithBrowser:[MyBrowser browser]];
[windowController.browser addBlankTabInForeground:YES];
[windowController showWindow:self];
}
MyBrowser.mm:
-(CTTabContents*)createBlankTabBasedOn:(CTTabContents*)baseContents {
// Create a new instance of our tab type
MyTabContents *contents = [[MyTabContents alloc]
initWithBaseTabContents:baseContents];
[self changeLayout];
return [contents autorelease];
}
I see a lot of questions about this subject but am unable to find a solution to the problem I am experiencing. I have created an iPad app that should be Landscape only - it works fine when ran on any os prior to iOS6 but on iOS6 the app opens in portrait view. This screenshot shows what I mean (sorry not a great explanation) http://s1342.beta.photobucket.com/user/designedbyria/media/ScreenShot2012-11-02at122113.png.html
I'm guessing the problem is somewhere in the below code, but I can't be sure. I have set the supported Interface Orientations to Landscape Left and Landscape Right only - but this has not worked. I have also taken a look at the questions here with no luck..
I am using xcode and cordova/phonegap

I had the same problem (but not using cordova/phonegap).
You have to set your view controller as a RootViewController in your appDelegate instead of just adding as a subview.
Replace in you appdelegate:
[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];
By
[self.window setRootViewController:self.viewController];
[self.window makeKeyAndVisible];
You can use the delegate
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
Using this delegate and the application will be present in Landscape mode or any desired orientation mode.
Try it.
I'm trying to write an application that allows the user to drag files from the Finder and drop them onto an NSStatusItem. So far, I've created a custom view that implements the drag and drop interface. When I add this view as a subview of an NSWindow it all works correctly -- the mouse cursor gives appropriate feedback, and when dropped my code gets executed.
However, when I use the same view as an NSStatusItem's view it doesn't behave correctly. The mouse cursor gives appropriate feedback indicating that the file can be dropped, but when I drop the file my drop code never gets executed.
Is there something special I need to do to enable drag and drop with an NSStatusItem?
I finally got around to testing this and it works perfectly, so there's definitely something wrong with your code.
Here's a custom view that allows dragging:
#implementation DragStatusView
- (id)initWithFrame:(NSRect)frame
{
self = [super initWithFrame:frame];
if (self) {
//register for drags
[self registerForDraggedTypes:[NSArray arrayWithObjects: NSFilenamesPboardType, nil]];
}
return self;
}
- (void)drawRect:(NSRect)dirtyRect
{
//the status item will just be a yellow rectangle
[[NSColor yellowColor] set];
NSRectFill([self bounds]);
}
//we want to copy the files
- (NSDragOperation)draggingEntered:(id<NSDraggingInfo>)sender
{
return NSDragOperationCopy;
}
//perform the drag and log the files that are dropped
- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender
{
NSPasteboard *pboard;
NSDragOperation sourceDragMask;
sourceDragMask = [sender draggingSourceOperationMask];
pboard = [sender draggingPasteboard];
if ( [[pboard types] containsObject:NSFilenamesPboardType] ) {
NSArray *files = [pboard propertyListForType:NSFilenamesPboardType];
NSLog(#"Files: %#",files);
}
return YES;
}
#end
Here's how you'd create the status item:
NSStatusItem* item = [[[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength] retain];
DragStatusView* dragView = [[DragStatusView alloc] initWithFrame:NSMakeRect(0, 0, 24, 24)];
[item setView:dragView];
[dragView release];
Since Yosemite, the method for setting a view on NSStatusItem is deprecated but fortunately there is a much nicer way using the new NSStatusItemButton property on NSStatusItem:
- (void)applicationDidFinishLaunching: (NSNotification *)notification {
NSImage *icon = [NSImage imageNamed:#"iconName"];
//This is the only way to be compatible to all ~30 menu styles (e.g. dark mode) available in Yosemite
[normalImage setTemplate:YES];
statusItem.button.image = normalImage;
// register with an array of types you'd like to accept
[statusItem.button.window registerForDraggedTypes:#[NSFilenamesPboardType]];
statusItem.button.window.delegate = self;
}
- (NSDragOperation)draggingEntered:(id<NSDraggingInfo>)sender {
return NSDragOperationCopy;
}
- (BOOL)performDragOperation:(id<NSDraggingInfo>)sender {
//drag handling logic
}
Please be aware that the button property is only available starting in 10.10 and you might have to keep your old solution if you support 10.9 Mavericks or below.
