 Shake the view using the specified options.
 |shakeOptions| is an enum of options that can be activated by using the OR operator (like SCShakeOptionsDirectionRotate | SCShakeOptionsForceInterpolationNone).
 
 |force| is the coefficient of force to apply on each shake iteration (typically between 0 and 1 even though nothing prevents you for setting a higher value if you want).
 
 |duration| is the total duration of the shaking motion. This may be ignored depending of the options you set.
 iterationDuration is how long each shake iteration will last. You may want to set a very low value (like 0.02) if you want a proper shake effect.
 
 |completionHandler|, if not null, is the block that will be invoked when the shake finishes.
