 6 | `UIViewController` extension to present view / view controller as bottom-half modal. 
 7 | 
 8 | <p align="center">
 9 |   <img src="Demo.gif" width="30%">
10 | </p>
11 | 
12 | ## Installation
13 | 
14 | ### CocoaPods
15 | 
16 | ```ruby
17 | pod 'SemiModalViewController'
18 | ```
19 | 
20 | ### Swift Package Manager
21 | 
22 | ```swift
23 | dependencies: [
24 |     .Package(url: "https://github.com/muyexi/SemiModalViewController.git", majorVersion: 0)
25 | ]
26 | ```
27 | 
28 | ## Usage
29 | 
30 | Present a view controller:
31 | 
32 | ```swift
33 | let options = [
34 |     SemiModalOption.pushParentBack: true
35 | ]
36 | 
37 | let controller = UIViewController()
38 | 
39 | controller.view.height = 200
40 | controller.view.backgroundColor = UIColor.redColor()
41 | 
42 | presentSemiViewController(controller, options: options, completion: {
43 |     print("Completed!")
44 | }, dismissBlock: {
45 |     print("Dismissed!")
46 | })
47 | ```
48 | 
49 | Or view:
50 | 
51 | ```swift
52 | let view = UIView(frame: UIScreen.mainScreen().bounds)
53 | view.height = 300
54 | view.backgroundColor = UIColor.redColor()
55 | 
56 | presentSemiView(view, options: options) {
57 |     print("Completed!")
58 | }
59 | ```
60 | 
61 | Dismiss a presented view / view controller:
62 | 
63 | ```swift
64 | dismissSemiModalView()
65 | ```
66 | 
67 | Default options:
68 | 
69 | ```swift
70 | SemiModalOption.traverseParentHierarchy : true,
71 | SemiModalOption.pushParentBack          : false,
72 | SemiModalOption.animationDuration       : 0.5,
73 | SemiModalOption.parentAlpha             : 0.5,
74 | SemiModalOption.parentScale             : 0.8,
75 | SemiModalOption.shadowOpacity           : 0.5,
76 | SemiModalOption.transitionStyle         : .slideUp,
77 | SemiModalOption.disableCancel           : true
78 | ```
