UITextField+Shake

Setup with Cocoapods

  • Add pod 'UITextField+Shake' to your Podfile
  • Run pod install
  • Run open App.xcworkspace
  • Import UITextField+Shake.h in your controller's header file

Usage

// 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
             andSpeed:0.03 // 30ms per shake
];

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

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 andSpeed:(NSTimeInterval)interval shakeDirection:(ShakeDirection)shakeDirection completion:(void((^)()))handler;
