 {
    [UIView animateKeyframesWithDuration:0.3 delay:0  
         options:UIViewAnimationCurveEaseOut 
         animations:^{
                              CGRect frame = self.toplayer.frame;
                              frame.origin.x = x;
                              self.toplayer.frame = frame;
                          }
                          completion:^(BOOL finished){

                          }];

   }

use this option instead:

 UIViewAnimationOptionCurveEaseOut

That's really all you need to change to make the warning to away.

Use of this method is discouraged in iOS 4.0 and later. Instead, you should use theanimateWithDuration:delay:options:animations:completion: method to specify your animations and the animation curve options.

You need to use: UIViewKeyframeAnimationOptions enum for fixing the issue.

animateKeyframesWithDuration: takes UIViewKeyframeAnimationOptions option as it's 3rd argument. You are passing the UIViewAnimationCurve enum instead of UIViewKeyframeAnimationOptions.

Reference:

animateKeyframesWithDuration:delay:options:animations:completion:

Creates an animation block object that can be used to set up keyframe-based animations for the current view.

+ (void)animateKeyframesWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewKeyframeAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion

Parameters

duration

The duration of the overall animation, measured in seconds. If you specify a negative value or 0, changes are made immediately and without animations.

delay

Specifies the time (in seconds) to wait before starting the animation.

options

A mask of options indicating how you want to perform the animations. For a list of valid constants, see “UIViewKeyframeAnimationOptions”.

animations

A block object containing the changes to commit to the views. Typically, you call the addKeyframeWithRelativeStartTime:relativeDuration:animations: method one or more times from inside this block. You may also change view values directly if you want those changes to animate over the full duration. This block takes no parameters and has no return value. Do not use a nil value for this parameter. completion

A block object to be executed when the animation sequence ends. This block has no return value and takes a single Boolean argument that indicates whether or not the animations finished before the completion handler was called. If the duration of the animation is 0, this block is performed at the beginning of the next run loop cycle. You can use a nil value for this parameter.

According to apples docs, the options should be.

UIViewKeyframeAnimationOptions Key frame animation options used with the animateKeyframesWithDuration:delay:options:animations:completion: method. So your Options should be as below.

typedef enum {
   UIViewKeyframeAnimationOptionLayoutSubviews            = UIViewAnimationOptionLayoutSubviews,
   UIViewKeyframeAnimationOptionAllowUserInteraction      = UIViewAnimationOptionAllowUserInteraction,
   UIViewKeyframeAnimationOptionBeginFromCurrentState     = UIViewAnimationOptionBeginFromCurrentState,
   UIViewKeyframeAnimationOptionRepeat                    = UIViewAnimationOptionRepeat,
   UIViewKeyframeAnimationOptionAutoreverse               = UIViewAnimationOptionAutoreverse,
   UIViewKeyframeAnimationOptionOverrideInheritedDuration = UIViewAnimationOptionOverrideInheritedDuration,
   UIViewKeyframeAnimationOptionOverrideInheritedOptions  = UIViewAnimationOptionOverrideInheritedOptions,

   UIViewKeyframeAnimationOptionCalculationModeLinear     = 0 << 9,
   UIViewKeyframeAnimationOptionCalculationModeDiscrete   = 1 << 9,
   UIViewKeyframeAnimationOptionCalculationModePaced      = 2 << 9,
   UIViewKeyframeAnimationOptionCalculationModeCubic      = 3 << 9,
   UIViewKeyframeAnimationOptionCalculationModeCubicPaced = 4 << 9
} UIViewKeyframeAnimationOptions;

Otherwise It will show warning and in 64-bit application, it may lead to serious issue.
