in iOS 7 there is no problem for this method:
_rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
[_rootViewController presentViewController:self animated:NO completion:nil];
But in iOS 8 it did nothing.How to solve it? Is it a Bug for iOS 8？
My answer is more simple, below code. This works in iOS8 (XCode6 GM seed).
HogeViewController *vc = [[HogeViewController alloc] init];
vc.modalPresentationStyle = UIModalPresentationOverFullScreen;
[self presentViewController:vc animated:NO completion:nil];
Note this workaround was needed on xcode6_beta7. The lastest xcode6
has the UIModalPresentationOver* styles fixed. So, I'm just assigning them to myModalViewController.modalPresentationStyle and now it works ok.
Finally made it work in iOS 8 after reading the UIPresentationController help and this post
appDelegate.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
MyModalController *myModalController = [[MyModalController alloc] initWithNibName:#"MyModalController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myModalController];
navController.modalPresentationStyle = UIModalPresentationCustom;
navController.transitioningDelegate = myModalController;
[self.navigationController presentViewController:navController animated:YES completion:nil];
You can make the modal view controller inherit from UIViewControllerTransitioningDelegate
#interface MyModalController : UIViewController <UIViewControllerTransitioningDelegate>
and override presentationControllerForPresentedViewController:...
-(UIPresentationController *)presentationControllerForPresentedViewController:(UIViewController *)presented presentingViewController:(UIViewController *)presenting sourceViewController:(UIViewController *)source
{
if (presented == self) {
return [[TransparentPresentationController alloc] initWithPresentedViewController:presented presentingViewController:presenting];
} else {
return nil;
}
}
returning an instance of TransparentPresentationController which inherits from UIPresentationController
#interface TransparentPresentationController : UIPresentationController
and overrides shouldRemovePresentersView
- (BOOL) shouldRemovePresentersView {
return NO;
}

I am using xcode 7.3 and using following code to open MfMailComposeViewController and object of mail composer goes nil after alloc init it.
- (void)openMailComposer {
NSString *emailTitle = #"Invite for SpotFit";
MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
mailVC.mailComposeDelegate = self;
[mailVC setSubject:emailTitle];
[mailVC setMessageBody:AppLink isHTML:NO];
[self presentViewController:mailVC animated:NO completion:nil];
}
Please provide any solution for it.
In iOS 8, setting the preferredDisplayMode on a UISplitViewController to PrimaryOverlay is generating the following warning:
"Unbalanced calls to begin/end appearance transitions for UINavigationController"
There is no problem if I set preferredDisplayMode to AllVisible or don't set it at all. Problem occurs for all iPads and iPhones in the simulator that I've tried. Problem occurs whether the app starts up in portrait or landscape.
Here's some very simple code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITableViewController *tableViewController = [[UITableViewController alloc] init];
UIViewController *viewController = [[UIViewController alloc] init];
UINavigationController *masterNavController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
UINavigationController *detailNavController = [[UINavigationController alloc] initWithRootViewController:viewController];
UISplitViewController *svc = [[UISplitViewController alloc] init];
[svc addChildViewController:masterNavController];
[svc addChildViewController:detailNavController];
//svc.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible;
svc.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay;
self.window.rootViewController = svc;
[self.window makeKeyAndVisible];
return YES;
}
Wrap your display code in dispatch_async. Otherwise iOS seems to get confused with other animations running at the same time.
dispatch_async(dispatch_get_main_queue(), ^{
svc.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay;
});
or
dispatch_async(dispatch_get_main_queue()) {
svc.preferredDisplayMode = .PrimaryOverlay
}
Following are the main poins I have.
I'm new to IOS development
I need to support IOS 5 and IOS 6 in my IOS app
I have a UITabBarController in AppDeligate file as follows.
UIViewController *viewController1 = [[[Grid1ViewController alloc] initWithNibName:#"Grid1ViewController" bundle:nil] autorelease];
UIViewController *viewController2 = [[[VideoListViewController alloc] initWithNibName:#"VideoListViewController" bundle:nil] autorelease];
UIViewController *viewController3 = [[[MusicViewController alloc] initWithNibName:#"MusicViewController" bundle:nil] autorelease];
UIViewController *viewController4 = [[[GalleryViewController alloc] initWithNibName:#"GalleryViewController" bundle:nil]autorelease];
UINavigationController *myNav1=[[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController *myNav2=[[UINavigationController alloc] initWithRootViewController:viewController2];
UINavigationController *myNav3=[[UINavigationController alloc] initWithRootViewController:viewController3];
UINavigationController *myNav4=[[UINavigationController alloc] initWithRootViewController:viewController4];
UIImage *navBackgroundImg = [UIImage imageNamed:#"aa.png"];
[myNav1.navigationBar setBackgroundImage:navBackgroundImg forBarMetrics:UIBarMetricsDefault];
[myNav2.navigationBar setBackgroundImage:navBackgroundImg forBarMetrics:UIBarMetricsDefault];
[myNav3.navigationBar setBackgroundImage:navBackgroundImg forBarMetrics:UIBarMetricsDefault];
[myNav4.navigationBar setBackgroundImage:navBackgroundImg forBarMetrics:UIBarMetricsDefault];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:myNav1, myNav2, myNav3,myNav4,nil];
4.I want to lock the rotation of every controller which is directly connected to tabBarController( ex - Grid1ViewController). But I need to rotate the some controller which are used in the app. Please refer the following drawing. A,B,C,D and E are controllers.
I tried implementing following method in controllers and AppDeligate file. But didn't work. When rotation are allowed the whole app start to rotate.
(BOOL)shouldAutorotateToInterfaceOrientation(UIInterfaceOrientation)toInterfaceOrientation{
NSLog(#"5 rotation");
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
// For IOS 6
-(BOOL)shouldAutorotate {
NSLog(#"shouldAutorotate");
return YES;
}
(NSUInteger)supportedInterfaceOrientations {
NSLog(#"6 rotation");
return UIInterfaceOrientationMaskPortrait;
}
How can I achieve this? Please help. Thank you in advance.
I am trying to make an actionsheet for another button but I get two errors: "No visible #interface for 'UIstoryboard' declares the selector 'InitiateViewControll:' and, "No visible #interface for SWViewController' declares the selector 'presentViewController:animated:' I was giving this code so is there any names that I need to name in this to make this code costomized for my code? I am trying to learn i am a noob sorry :( here is the code I have so far:
- (IBAction)OpenActionSheetButton:(id)sender {
UIActionSheet *actionsheet = [[UIActionSheet alloc]initWithTitle:#"There is no going back, are you sure???" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Continue" otherButtonTitles:nil, nil];
[actionsheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) {
UIViewController *controller = [self.storyboard instantiateViewControll:#"storyboardViewName"];
//Push
[self.navigationController pushViewController:controller animated:YES];
//Modal
[self presentViewController:controller animated:YES];
}
}
Please help guys?
Try out this code..And SWViewController must have a Navigation Controller
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == 0)
{
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"storyboardViewIdentifier"];
//storyboardViewIdentifier is the ViewController identifier you specify in the storyboard
//PUSH
[self.navigationController pushViewController:controller animated:YES];
//Modal
[self presentViewController:controller animated:YES completion:Nil];
}
}
Try this. It works for me:
if(buttonIndex == 0)
{
NSString * storyboardName = #"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
Paypal_ViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"Paypal_ViewController"];
[self presentViewController:vc animated:YES completion:nil];
}
I've subclassed the UINavigationController as follows:
-(NSUInteger)supportedInterfaceOrientations {
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate {
return self.topViewController.shouldAutorotate;
}
However I've come unstuck on pushing a view controller in an initial orientation differing to its' parent. In my case the parent view is portrait only:
-(BOOL)shouldAutorotate {
return NO;
}
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
But I wish the pushed view to be landscape only - it'll only behave as such after manually changing the orientation of the device.
-(BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
I'd much appreciate anyone pointing me in the right direction. (I've only got a hacky solution so far...)
EDIT:
Following shows how I'm initiating the subclassed UINavigationController
PortraitView *vc = [[PortraitView alloc] init];
SubClassedNav *navController = [[SubClassedNav alloc] initWithRootViewController:vc];
[navController setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self presentViewController:navController animated:YES completion:nil];
And how I subsequently push a new view:
LandscapeView *vc = [[LandscapeView alloc] init];
[[self navigationController] pushViewController:vc animated:YES];
Double check that you setup [window setRootViewController:controller] in your AppDelegate.
