Usage

In Objective-C

// Shake
[[self.textField] shake];

// Shake with the default speed
[self.textField shake:10   // 10 times
            withDelta:5    // 5 points wide
];

// Shake with a custom speed
[self.textField shake:10   // 10 times
            withDelta:5    // 5 points wide
                speed:0.03 // 30ms per shake
];

// Shake with a custom speed and direction
[self.textField shake:10   // 10 times
            withDelta:5    // 5 points wide
                speed:0.03 // 30ms per shake
       shakeDirection:ShakeDirectionVertical
];

In Swift

// Shake
self.textField.shake()

// Shake with the default speed
self.textField.shake(10,              // 10 times
                     withDelta: 5.0   // 5 points wide
)

// Shake with a custom speed
self.textField.shake(10,              // 10 times
                     withDelta: 5.0,  // 5 points wide
                     speed: 0.03      // 30ms per shake
)

// Shake with a custom speed and direction
self.textField.shake(10,              // 10 times
                     withDelta: 5.0,  // 5 points wide
                     speed: 0.03,     // 30ms per shake
                     shakeDirection: ShakeDirection.Vertical
)

Completion Handler

You can also pass a completion block that will be performed as soon as the shake animation stops

- (void)shake:(int)times withDelta:(CGFloat)delta completion:(void((^)()))handler;
- (void)shake:(int)times withDelta:(CGFloat)delta speed:(NSTimeInterval)interval completion:(void((^)()))handler;
- (void)shake:(int)times withDelta:(CGFloat)delta speed:(NSTimeInterval)interval shakeDirection:(ShakeDirection)shakeDirection completion:(void((^)()))handler;

or in Swift using the trailing closure syntax:

textField.shake(10, withDelta: 5) {
    println("done")
}
