How get auto rotate in iPad? - xcode

In my application i added UITabBarController *rootController;
in didFinishLaunchingWithOptions i done this code.
for that i wrote
WaylistController *waylistNavigationControllerTemp = [[WaylistNavigationController alloc] initWithNibName:#"WaylistNavigationController" bundle:nil];
self.waylisyViewController = waylistNavigationControllerTemp;
UINavigationController * waylistNavigationController = [[UINavigationController alloc] initWithRootViewController:waylisyViewController];
[waylistNavigationControllerTemp release];
WayRoomController *wayRoomNavigationControllerrTemp = [[WayRoomNavigationController alloc] initWithNibName:#"WayRoomNavigationController" bundle:nil];
self.WayRoomViewController = wayRoomNavigationControllerrTemp;
UINavigationController * wayRoomNavigationController = [[UINavigationController alloc] initWithRootViewController:WayRoomViewController];
[wayRoomNavigationControllerrTemp release];
rootController.viewControllers = [NSArray arrayWithObjects: WaylistNavigationController,//0
WayRoomNavigationController,//1
nil]
[rootController setSelectedIndex:0];
for this i am not getting auto orient always getting patriot only. any one please help me?

Put this in your controller class to which you need the orientations.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) || (interfaceOrientation == UIInterfaceOrientationLanscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight))
return YES;
}
Also make sure that in your project setting you have enabled all the orientations.
In your .xib file use the autosizing to scale for both orientations.

Check Settings in .plist file for Supported interface orientation..

How to present a semi-transparent (half-cut) viewcontroller in iOS 8

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;
}

Lock screen orientation for a single controller when there's a UITabBar in IOS 5 & 6

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.

Manage memory allocation issue on Map iOS

In my iPhone app I have a map view. In this I am displaying a number of pin views depends on the data from a web server. Here is the method I used for it.
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
NSString *identifier = #"myPin";
self.pinView = (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (self.pinView == nil) {
self.pinView= [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier]autorelease]; //11.1%
} else {
self.pinView.annotation = annotation;
}
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; //20.4%
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
self.pinView.rightCalloutAccessoryView = rightButton; //2.7%
MyAnnotation *annot = (MyAnnotation*)annotation;
UIImageView *egoimageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"defaultPerson"]]; //17.5%
NSString *imageUrl = [NSString stringWithFormat:#"%#%#", CommonImageURL, [friendsProfileImageArray objectAtIndex:annot.tag]]; //9.4%
if ([[UIScreen mainScreen] respondsToSelector:#selector(displayLinkWithTarget:selector:)] &&
([UIScreen mainScreen].scale == 2.0)) {
// Retina display
[egoimageView setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:#"defaultPerson#2x.png"]]; //2.6%
egoimageView.image = [UIImage imageWithCGImage:egoimageView.image.CGImage scale:egoimageView.image.size.width/25 orientation:egoimageView.image.imageOrientation];
} else {
// non-Retina display
[egoimageView setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage imageNamed:#"defaultPerson.png"]]; //14.6%
egoimageView.image = [UIImage imageWithCGImage:egoimageView.image.CGImage scale:egoimageView.image.size.width/25 orientation:egoimageView.image.imageOrientation]; //1.6%
}
[egoimageView sizeToFit];
self.pinView.leftCalloutAccessoryView = egoimageView; //3.1%
[egoimageView release];
self.pinView.canShowCallout=YES;
self.pinView.animatesDrop=YES;
//pin color based on status.....
if ([annot.relationshipStatus intValue]==2 )
self.pinView.pinColor=MKPinAnnotationColorGreen;
else
self.pinView.pinColor=MKPinAnnotationColorPurple; //17.1%
return self.pinView;
}
In this I have mentioned the percentage of memory allocations. If I continuously load the map, the total memory usage increases and the app crashes. How can I properly fix this? I have tried to fix it, but I don't know what more I can do.
Please help, thanks in advance.

How To Provide Search-As-You-Type Filtering With UICollectionView?

I have a UICollectionView added to a ViewController. The UICollectionView displays a grid of items with peoples names on each cell.
I would like to add search as you type functionality that will filter the UICollectionView as the user types in their name to a searchbar or UITextField on the ViewController so that it doesn't scroll with the content in the UICollectionView.
Even though a few places I have read that UICollectionView is similar to UITableView I don't see that implementing this filter/search functionality is the same in UICollectionView as it is with UITableView and need some help with it.
Does anyone have a good example of doing this search/filter as you type functionality with UICollectionView?
I solved it by doing the following (hope it helps somebody else):
I populate my UICollectionView from CoreData into an NSArray:
self.allCVData = [context executeFetchRequest:fetchRequest error:&error];
then add my NSArray to an NSMutableArray so that I can use that for filtering on the UICollection:
self.filteredCVData = [[NSMutableArray alloc] initWithArray:allCVData];
Added a UITextField and called it searchField.
Added a selector in viewDidLoad:
[mytextfield addTarget:self action:#selector(textDidChange:) forControlEvents:UIControlEventEditingChanged];
Added a method to accept changes in the UITextField:
-(void) textDidChange:(id)sender
{
UITextField* searchField = (UITextField *) sender;
if(searchField.text.length == 0)
{
self.isFiltered = FALSE;
[self.filteredCVData removeAllObjects];
[self.filteredCVData addObjectsFromArray:self.allCVData];
}
else
{
self.isFiltered = true;
[self.filteredCVData removeAllObjects];
self.filteredCVData = [[NSMutableArray alloc] init];
LogInfo(#"Before Looping in allCVData Array.");
for (OLPerson* person in allCVData)
{
NSRange firstnameRange = [person.firstname rangeOfString:searchField.text options:NSCaseInsensitiveSearch];
NSRange surnameRange = [person.surname rangeOfString:searchField.text options:NSCaseInsensitiveSearch];
if(firstnameRange.location != NSNotFound || surnameRange.location != NSNotFound)
{
[self.filteredCVData addObject:person];
}
}
}
[self.collectionView reloadData];
}

xcode iOS6 orientation landscape

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.
