By completing image puzzle game, TTGPuzzleVerify is a more user-friendly verification tool on iOS, which is highly customizable and easy to use. It supports square, circle, classic or custom puzzle shape. User can complete the verification by sliding horizontally, vertically or directly dragging the puzzle block.

Features

  • More user-friendly
  • Highly Customizable
  • Classic, square, circle or custom puzzle shape
  • Slide horizontally or vertically or drag the puzzle directly

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

iOS 7 and later.

Installation

TTGPuzzleVerify is available through CocoaPods. To install it, simply add the following line to your Podfile:

Usage

TTGPuzzleVerifyView

Basic use

// Import
#import <TTGPuzzleVerify/TTGPuzzleVerifyView.h>

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // Create TTGPuzzleVerifyView instance
    _puzzleVerifyView = [[TTGPuzzleVerifyView alloc] initWithFrame:CGRectMake(20, 20, 320, 200)];
    [self.view addSubview:_puzzleVerifyView];
    
    // Set image
    _puzzleVerifyView.image = [UIImage imageNamed:@"pic"];
    
    // Set the puzzle blank position
    _puzzleVerifyView.puzzleBlankPosition = CGPointMake(200, 40);
    
    // Set init puzzle position
    _puzzleVerifyView.puzzlePosition = CGPointMake(10, 40);
    
    // Callback
    [_puzzleVerifyView setVerificationChangeBlock:^(TTGPuzzleVerifyView *view, BOOL isVerified) {
        if (isVerified) {
            // User complete the verification
        }
    }];
}

// On slide changed
- (IBAction)onSliderChange:(UISlider *)sender {
    // Update position
    _puzzleVerifyView.puzzleXPercentage = sender.value;
}

API

Puzzle pattern types

/**
 * TTGPuzzleVerifyView pattern type
 */
typedef NS_ENUM(NSInteger, TTGPuzzleVerifyPattern) {
    TTGPuzzleVerifyClassicPattern = 0, // Default
    TTGPuzzleVerifySquarePattern,
    TTGPuzzleVerifyCirclePattern,
    TTGPuzzleVerifyCustomPattern
};

// Puzzle pattern, default is TTGPuzzleVerifyClassicPattern
@property (nonatomic, assign) TTGPuzzleVerifyPattern puzzlePattern;

// Custom path for puzzle shape. Only work when puzzlePattern is TTGPuzzleVerifyCustomPattern
@property (nonatomic, strong) UIBezierPath *customPuzzlePatternPath;

Complete the puzzle with animation

/**
 Complete verification. Call this with set the puzzle to its original position and fill the blank.

 @param withAnimation if show animation
 */
- (void)completeVerificationWithAnimation:(BOOL)withAnimation;

Callback

/**
 * Verification changed callback delegate
 */
@protocol TTGPuzzleVerifyViewDelegate <NSObject>
@optional
- (void)puzzleVerifyView:(TTGPuzzleVerifyView *)puzzleVerifyView didChangedVerification:(BOOL)isVerified;

- (void)puzzleVerifyView:(TTGPuzzleVerifyView *)puzzleVerifyView didChangedPuzzlePosition:(CGPoint)newPosition
             xPercentage:(CGFloat)xPercentage yPercentage:(CGFloat)yPercentage;
@end

// Callback block and delegate
@property (nonatomic, weak) id <TTGPuzzleVerifyViewDelegate> delegate; // Callback delegate
@property (nonatomic, copy) void (^verificationChangeBlock)(TTGPuzzleVerifyView *puzzleVerifyView, BOOL isVerified); // verification changed callback block

Puzzle image

@property (nonatomic, strong) UIImage *image; // Image for verification

Puzzle size and position

// Puzzle rect size,not for TTGPuzzleVerifyCustomPattern pattern
@property (nonatomic, assign) CGSize puzzleSize;

// Puzzle current position
@property (nonatomic, assign) CGPoint puzzlePosition;

// Puzzle current X and Y position percentage, range: [0, 1]
@property (nonatomic, assign) CGFloat puzzleXPercentage;
@property (nonatomic, assign) CGFloat puzzleYPercentage;

Puzzle verification

// Verification
@property (nonatomic, assign) CGFloat verificationTolerance; // Verification tolerance, default is 8
@property (nonatomic, assign, readonly) BOOL isVerified; // Verification boolean

Style

/**
