Modality currently has the following: 23 | 24 | * `MODTransitionAnimatorSlideModal` 25 | * `MODTransitionAnimatorFlipModal` 26 | * `MODTransitionAnimatorFade` 27 | * `MODTransitionAnimatorMask` 28 | * `MODTransitionAnimatorCarryOver` 29 | 30 | Then, for example, import: 31 | 32 | ```obj-c 33 | #import 34 | ``` 35 | 36 | Each animator will import the required headers to configure the transition. 37 | 38 | ###Creating the transition animator 39 | 40 | Create the transition animator using its factory method: 41 | 42 | ```obj-c 43 | MODTransitionAnimatorSlideModal *animator = [MODTransitionAnimatorSlideModal transitionAnimatorWithDirection:MODDirectionBottom destinationViewLength:200]; 44 | ``` 45 | 46 | ###Setting up the transition 47 | 48 | If you are presenting the view controller manually, do the following (this is a category method for UIViewController): 49 | 50 | ```obj-c 51 | [self MOD_presentViewController:modalController withTransitionAnimator:animator duration:MODDefaulTransitionDuration completion:nil]; 52 | ``` 53 | 54 | Else, if you are presenting through the Storyboard, do the following: 55 | 56 | ```obj-c 57 | - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 58 | ... 59 | UIViewController *destinationController = segue.destinationViewController; 60 | [destinationController MOD_animateWithTransitionAnimator:animator duration:MODDefaulTransitionDuration]; 61 | ``` 62 | 63 | ##Author 64 | 65 | Comments and suggestions much welcome 66 | 67 | Kevin Wong, [@kevinwl02](https://twitter.com/kevinwl02) 68 | 69 | ##License 70 | 71 | Code distributed under the [MIT license](LICENSE) -------------------------------------------------------------------------------- /Modality/Categories/UIViewController+Modality.m: -------------------------------------------------------------------------------- 1 | // 2 | // UIViewController+Modality.m 3 | // Modality 4 | // 5 | // Created by Kevin on 12/11/14. 6 | // Copyright (c) 2014 Kevin Wong.
