Am presenting
[window addSubview:navigationController.view];
[window makeKeyAndVisible];
LicenceAgreementViewController *licenceAgreementViewController = [[LicenceAgreementViewController alloc] initWithNibName:#"LicenceAgreementViewController" bundle:nil];
[self.navigationController presentViewController :licenceAgreementViewController animated:YES completion:nil];
[licenceAgreementViewController release];
And also did some changes in .plist itself
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskAll;
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
// orientations = [presentedViewController supportedInterfaceOrientations];
}

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
}
I get this error on Xcode 5:

If you are using storyboard click on the project name in project navigator in Xcode. Then look for deployment info. Select Main Interface as your storyboard name. In app delegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// // Override point for customization after application launch.
// self.window.backgroundColor = [UIColor whiteColor];
// [self.window makeKeyAndVisible];
return YES;
}
And now try it.
I want to implement the functionality of pan gesture to a imageview, this imageview is a subview of a scroll view. the problem is when i try to scroll the scrollview the pan gesture of the imageview gets recognized, and the scrollview does not scroll.
please help me with this.
this is the code for initializing the pan to the uiimageview:
UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(move:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
[panRecognizer setDelegate:self];
[[[scrollView subviews] objectAtIndex:i] addGestureRecognizer:panRecognizer];
the imageview has the user set to "YES"
and the action for it
-(void)move:(UIPanGestureRecognizer *)sender
{
[[[[[sender view] superview] superview] superview] bringSubviewToFront:sender.view];
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateBegan) {
if ([[[sender view] superview] superview] == itemView) // adds the imageview in the item scroll
{
int tag = [[sender view] tag] / 100;
UIScrollView *tempScroll = (UIScrollView *)[itemView viewWithTag:-tag];
CGRect frame = CGRectFromString([itemFrameDict objectForKey:[NSString stringWithFormat:#"%i",[[sender view] tag]]]);
CGAffineTransform transform = temp.transform;
UIImageView *tempImageView = [[UIImageView alloc] initWithImage: [(UIImageView *) [sender view] image]];
tempImageView.tag = [[sender view] tag];
//NSLog(#"[sender view] superview] : %#", [[sender view] superview]);
tempImageView.frame = frame;
[tempImageView setTransform:transform];
[tempImageView setFrame:frame];
[tempImageView setUserInteractionEnabled:YES];
[tempScroll addSubview:tempImageView];
UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(move:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
[panRecognizer setDelegate:self];
[tempImageView addGestureRecognizer:panRecognizer];
UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleSingleTap:)];
[singleTapGestureRecognizer setNumberOfTapsRequired:1];
[tempImageView addGestureRecognizer:singleTapGestureRecognizer];
}
}
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateChanged)
{
CGPoint translatedPoint = [sender locationInView:[[sender view] superview]] ;
newTranslatedPoint = [[[sender view] superview] convertPoint:translatedPoint toView:self.view];
if ([sender view].frame.size.width == 35 && [sender view].frame.size.height == 35)
[[sender view] sizeToFit];
[sender view].center = CGPointMake(newTranslatedPoint.x, newTranslatedPoint.y); //startFrame;
[self.view addSubview:[sender view]];
}
if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded)
{
CGPoint newPoint = [[[sender view] superview] convertPoint:newTranslatedPoint toView:itemView];
if (newPoint.y < 0)// || !viewUp)
{
//NSLog(#" baseView");
[baseView addSubview:[sender view]];
UITapGestureRecognizer *doubleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleDoubleTap:)];
[doubleTapGestureRecognizer setNumberOfTapsRequired:2];
[[sender view] addGestureRecognizer:doubleTapGestureRecognizer];
UIPinchGestureRecognizer *pinchRecognizer = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:#selector(scale:)];
[pinchRecognizer setDelegate:self];
[[sender view] addGestureRecognizer:pinchRecognizer];
UIRotationGestureRecognizer *rotationRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:#selector(rotate:)];
[rotationRecognizer setDelegate:self];
[[sender view] addGestureRecognizer:rotationRecognizer];
}
else if (newPoint.y > 0)// && viewUp )
{
//NSLog(#" itemView");
int tag = [[sender view] tag] / 100;
UIScrollView *tempScroll = (UIScrollView *)[itemView viewWithTag:-tag];
CGRect frame = CGRectFromString([itemFrameDict objectForKey:[NSString stringWithFormat:#"%i",[[sender view] tag]]]);
CGAffineTransform transform = temp.transform;
[[sender view] setTransform:transform];
[[sender view] setFrame:frame];
[tempScroll addSubview:[sender view]];
}
}
}
I'm not sure I understand what you're trying to achieve exactly by using a UIPanGestureRecognizer on a UIImageView that is already in a UIScrollView. But from your description, it sounds like you want the UIScrollView to do it's thing and for the UIPanGestureRecognizer to not block that. I believe you need to implement this delegate method for your UIPanGestureRecognizer:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
return YES;
}
Please read the UIGestureRecognizerDelegate Protocol reference in regards to allowing simultaneous gesture recognition. According to the documentation:
The default implementation returns NO—no two gestures can be
recognized simultaneously.
/* EDIT */
From UIPanGestureRecognizer - Only vertical or horizontal:
Implement just one direction for a UIPanGestureRecognizer. This is for a vertical pan:
- (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)panGestureRecognizer {
CGPoint translation = [panGestureRecognizer translationInView:someView];
return fabs(translation.y) > fabs(translation.x);
}
After picking image from UIImagePickerController I want to Tweet it but there is error!
Warning: Attempt to present <SLTwitterComposeViewController: 0x210d84b0> on <UITabBarController: 0x1fd67650> while a presentation is in progress!
P.S
This is tabbar application (4 tabbars)
All code:
-(void)useCamera:(id)sender
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
UIImagePickerController *imagePicker =[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = #[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = NO;
[self presentViewController:imagePicker animated:YES completion:nil];
_newMedia = YES;
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSString *mediaType = info[UIImagePickerControllerMediaType];
[self dismissViewControllerAnimated:YES completion:nil];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}
- (IBAction)buttonTweet:(id)sender {
SLComposeViewController *composeController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[composeController setInitialText:[NSString stringWithFormat:#"#this is tweet text"]];
[composeController addImage:sender];
[composeController addURL: [NSURL URLWithString:#"http://www.abc.com"]];
[self presentViewController:composeController animated:YES completion:nil];
}
You are presenting a new view controller while the old one is still disappearing. You can present the new one upon completion of the other animation by doing it like this:
[self dismissViewControllerAnimated:YES completion:^{
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
[self buttonTweet:info[UIImagePickerControllerOriginalImage]];
}
}];
I have animation code in my AppDelegate file thats making the Default.png splashscreen to fade
out to the first controller of the app.
Since I implemented TabBar in my code, the animation stopped working.
Any idea why?
- (void) splashFade
{
splashView = [[UIImageView alloc]
initWithFrame:CGRectMake(0,0, 320, 480)];
splashView.image = [UIImage imageNamed:#"Default.png"];
[_window addSubview:splashView];
[_window bringSubviewToFront:splashView];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView
setAnimationTransition:UIViewAnimationTransitionNone
forView:_window cache:YES];
[UIView setAnimationDelegate:self];
[UIView
setAnimationDidStopSelector:
#selector(startupAnimationDone:finished:context:)];
splashView.alpha = 0.0;
[UIView commitAnimations];
}
- (void)startupAnimationDone:(NSString *)animationID
finished:(NSNumber *)finished
context:(void *)context
{
[splashView removeFromSuperview];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
sleep(2);
[self splashFade];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[RootViewController alloc] initWithNibName:#"RootViewController" bundle:nil];
UIViewController *viewController2 = [[TableViewController alloc] initWithNibName:#"TableViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;
[self.window addSubview:self.rootViewController.view];
[self.window addSubview:self.navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
Try using
[self performSelector:#selector(splashFade) withObject:nil afterDelay:2];
better than sleep(2);
