ICPatternLock is a screen lock for your app access. It's familiar to most people and intuitively clear, because a pattern is much more easy to remember. What is more, it's also convenient for developers to use, of course, and to extend.

Example

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

Requirements

Installation

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

pod "ICPatternLock"

Convenience Usage

If you don't care much about the view display and some interactions, just use the ICPatternLockManager to present the pattern lock and receive the result. Of cource you can cusomize your GUI(e.g. color & text & preference) in this way. All what you need to do is just run your logic in the callback block. Check out the Demo Project to experience this.

To configure your pattern at the first time

if ([ICPatternLockManager isPatternSetted])
  {
      UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Hint"
                                                      message:@"Pattern already setted"
                                                     delegate:nil
                                            cancelButtonTitle:@"OK"
                                            otherButtonTitles:nil];
      [alert show];
  }
  else
  {
      [ICPatternLockManager showSettingPatternLock:self
                                          animated:YES
                                      successBlock:^(ICPatternLockViewController *controller){
          
                                          dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                                              
                                              [controller dismissViewControllerAnimated:YES completion:nil];
                                          });
                                      }];
  }

Verify the pattern you previously set

[ICPatternLockManager showVerifyPatternLock:self
                                         animated:YES
                                   forgetPwdBlock:^(ICPatternLockViewController *controller){
                                       
                                       NSLog(@"OMG~ forgot my pattern!~");
                                   }
                                     successBlock:^(ICPatternLockViewController *controller){
                                         
                                         dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                                             
                                             [controller dismissViewControllerAnimated:YES completion:nil];
                                         });
                                     }];

Modify the pattern

      [ICPatternLockManager showModifyPatternLock:self
                                         animated:YES
                                     successBlock:^(ICPatternLockViewController *controller) {
                                         
                                         dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                                             
                                             [controller dismissViewControllerAnimated:YES completion:nil];
                                         });
                                         
                                     }];

Customize Resource & Preference

Use api below to custom your own resource (text display & color) & preference (e.g. node size, key table) All key is defined in PLPreferencesKeyDef.h PLResourceTextKeyDef.h PLResourceColorKeyDef.h Change all the value or maybe just one of them if you like.

#pragma mark - Resource Bridge
+ (void)loadTextResource:(NSDictionary *)textInfo;
+ (void)loadColorResource:(NSDictionary *)colorInfo;

#pragma mark - Preferences
- (void)setPreferencesValue:(id)value forKey:(NSString *)key;

#pragma mark - PatternHandler
+ (void)setCustomizedPatternHandler:(id<ICPatternHandlerProtocol>)handler;

Flexible Usage

If you want to assemble this to your own logic, using ICPatternLockViewController directly, it has enough api for user. What's more, you can use ICPatternLockView to achive other goal if you like, imagination has no end！
