, когда я запускаю приложение и поворачиваю iPhone в альбомной ориентации, я загружаю другое представление (представление справки).Теперь, если я перехожу в другой вид с помощью одной из кнопок, присутствующих на главном экране, и поворачиваю iPhone, открывается вид справки ... Я хотел бы знать, как выполнить загрузку вида справки только когдам в первом представлении.Вот мой код .m:
@implementation Home
@synthesize ruota;
@synthesize portraitView,landscapeView;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView
{
}
*/
- (void)viewDidLoad
{
[super viewDidLoad];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(orientationChanged:)name:@"UIDeviceOrientationDidChangeNotification"
object:nil];
[self performSelector:@selector (ritardo) withObject:nil afterDelay:5.0f];
}
-(void)orientationChanged:(NSNotification *)object{
UIDeviceOrientation deviceOrientation = [[object object] orientation];
if (deviceOrientation == UIInterfaceOrientationPortrait)
{
[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
self.view = self.portraitView;
[UIView commitAnimations];
[self dismissModalViewControllerAnimated:YES];
} else if (deviceOrientation == UIInterfaceOrientationLandscapeLeft ||
deviceOrientation == UIInterfaceOrientationLandscapeRight) {
[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
self.view = self.landscapeView;
[UIView commitAnimations];
[self dismissModalViewControllerAnimated:YES];
}
}
-(void) ritardo {
ruota.image = [UIImage imageNamed:@"RuotaPerAiuto.png"];
}
- (void)viewDidUnload
{
[self setPortraitView:nil];
[self setLandscapeView:nil];
[self setRuota:nil];
[super viewDidUnload];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
@end
РЕДАКТИРОВАТЬ:
-(void)orientationChanged:(NSNotification *)object{
UIDeviceOrientation deviceOrientation = [[object object] orientation];
if (deviceOrientation == UIInterfaceOrientationPortrait)
{
if (self.isViewLoaded && self.view.window)
{
[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
self.view = self.portraitView;
[UIView commitAnimations];
[self dismissModalViewControllerAnimated:YES];
}
}
else if (deviceOrientation == UIInterfaceOrientationLandscapeLeft || deviceOrientation
== UIInterfaceOrientationLandscapeRight)
{
if (self.isViewLoaded && self.view.window)
{
[UIView beginAnimations:@"View Flip" context:nil];
