Am i write in right code?

VoodooBaba · June 2012

Hi, i am new in xcode. I learn it by myself so my knowledge is not much like you all. I hope you can share your knowledge and teach me to write with right one.

To the point, i'm writing code for flip animation between 2 view. This time my view can flip from main to other view and also can flip back to my main view. But the problem this time is, after flip to my main view, and i press again button, it can't flip to other view now, it flip only to my main view and so on and so on. please help.


#import \"FlipViewViewController.h\"

@interface FlipViewViewController ()

@end

@implementation FlipViewViewController
@synthesize yellowView;

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [self setYellowView:nil];
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

- (IBAction)gotoYellow:(id)sender {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1.0];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:[self view] cache:YES];
    yellowView.frame = [self view].bounds;
    [[self view] addSubview:yellowView];
    [UIView commitAnimations];
}

- (IBAction)gotoWhite:(id)sender {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1.0];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:[self view] cache:YES];
    [yellowView removeFromSuperview];
    [UIView commitAnimations];
}
@end

this is my .h file


#import <UIKit/UIKit.h>

@interface FlipViewViewController : UIViewController
@property (weak, nonatomic) IBOutlet UIView *yellowView;
- (IBAction)gotoYellow:(id)sender;
- (IBAction)gotoWhite:(id)sender;

@end

What do you mean that you found a solution but can't find the right one? What works, and what doesn't?

I would think you should be adding a new view and removing the old one in each of your button actions.
