This is my code for giving a crossdissolve effect for an image

- (void)viewDidLoad
{
    [super viewDidLoad];
    typedef enum
    {
        UIViewAnimationOptionTransitionCrossDissolve,
        UIViewAnimationOptionTransitionCurlDown,
        UIViewAnimationOptionTransitionCurlUp,
        UIViewAnimationOptionTransitionFlipFromBottom,
        UIViewAnimationOptionTransitionFlipFromLeft
} UIViewAnimationOptions;


    [UIView animateWithDuration:1.0 animations:^(void){

    [UIView setAnimationTransition: UIViewAnimationOptionTransitionCrossDissolve forView:img cache: YES];

    } completion:^(BOOL finished){
        [UIView animateWithDuration:1.0 animations:^(void){
            [UIView setAnimationTransition: UIViewAnimationOptionTransitionCrossDissolve forView:img cache: YES];
        } completion:^(BOOL finished){

        }];
    }];
}

But i am getting a warning implicit conversion from enumeration type 'enum UIViewAnimationOption to different enumeration type uiviewanimation transition.

But if i give UIViewAnimationTransitionFlipFromRight,UIViewAnimationTransitionCurlUp ..... it is working,but animatewithoptions is giving warning.

can anyone help me?

why are you typedef-ing the UIViewAnimationOptions enum? - wattson12
Removing typedef will solve your issue. - Mark Kryzhanouski
@wattson12 i add typedef inorder to remove that warning - Vork
the warning is there for a reason, it was telling you something is wrong - wattson12

You are using the enum of UIViewAnimationOption.

The enum defined for UIViewAnimationTransition is:

typedef enum {
   UIViewAnimationTransitionNone,
   UIViewAnimationTransitionFlipFromLeft,
   UIViewAnimationTransitionFlipFromRight,
   UIViewAnimationTransitionCurlUp,
   UIViewAnimationTransitionCurlDown,
} UIViewAnimationTransition;

Please check UIView Class for reference.

Also remove the enum defined by you, there is no need of it. The iOS already have the enum for UIView class.

You don't need to typedef the animation options enum, its already been done

The error is telling you what is wrong, you are passing in a type UIViewAnimationOption when the method expects a UIViewAnimationTransition

the valid options for animation transition are:

typedef enum {    
    UIViewAnimationTransitionNone,    
    UIViewAnimationTransitionFlipFromLeft,   
    UIViewAnimationTransitionFlipFromRight,    
    UIViewAnimationTransitionCurlUp,    
    UIViewAnimationTransitionCurlDown, 
} UIViewAnimationTransition;
