You can install it with the following command: 46 | 47 | ```bash 48 | $ gem install cocoapods 49 | ``` 50 | 51 | To integrate EasyTipView into your Xcode project using CocoaPods, specify it in your `Podfile`: 52 | 53 | 54 | ```ruby 55 | pod 'EasyTipView', '~> 2.1' 56 | ``` 57 | 58 | Then, run the following command: 59 | 60 | ```bash 61 | $ pod install 62 | ``` 63 | 64 | In case Xcode complains ("Cannot load underlying module for EasyTipView") go to Product and choose Clean (or simply press ⇧⌘K). 65 | 66 | 67 | ### Carthage 68 | 69 | [Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. 70 | 71 | You can install Carthage with [Homebrew](http://brew.sh/) using the following command: 72 | 73 | ```bash 74 | $ brew update 75 | $ brew install carthage 76 | ``` 77 | 78 | To integrate EasyTipView into your Xcode project using Carthage, specify it in your `Cartfile`: 79 | 80 | ```ogdl 81 | github "teodorpatras/EasyTipView" 82 | ``` 83 | 84 | Run `carthage update` to build the framework and drag the built `EasyTipView.framework` into your Xcode project. 85 | 86 | ### Manually 87 | 88 | If you prefer not to use either of the aforementioned dependency managers, you can integrate EasyTipView into your project manually. 89 | 90 | Supported OS & SDK Versions 91 | ----------------------------- 92 | 93 | * Supported build target - iOS 8+ (Xcode 8) 94 | 95 | Usage 96 | -------------- 97 | 98 | 1) First you should customize the preferences: 99 | ```swift 100 | 101 | var preferences = EasyTipView.Preferences() 102 | preferences.drawing.font = UIFont(name: "Futura-Medium", size: 13)! 103 | preferences.drawing.foregroundColor = UIColor.whiteColor() 104 | preferences.drawing.backgroundColor = UIColor(hue:0.46, saturation:0.99, brightness:0.6, alpha:1) 105 | preferences.drawing.arrowPosition = EasyTipView.ArrowPosition.top 106 | 107 | /* 108 | * Optionally you can make these preferences global for all future EasyTipViews 109 | */ 110 | EasyTipView.globalPreferences = preferences 111 | 112 | ``` 113 | 114 | 2) Secondly call the ``show(animated: forView: withinSuperview: text: preferences: delegate:)`` method: 115 | ```swift 116 | EasyTipView.show(forView: self.buttonB, 117 | withinSuperview: self.navigationController?.view, 118 | text: "Tip view inside the navigation controller's view. Tap to dismiss!", 119 | preferences: preferences, 120 | delegate: self) 121 | ``` 122 | 123 | **Note that if you set the** ```EasyTipView.globalPreferences```**, you can ommit the** ```preferences``` **parameter in all calls. Additionally, you can also ommit the** ``withinSuperview`` **parameter and the** ``EasyTipView`` **will be shown within the main application window**. 124 | 125 | *Alternatively, if you want to dismiss the ``EasyTipView`` programmatically later on, you can use one of the instance methods:* 126 | 127 | ```swift 128 | 129 | let tipView = EasyTipView(text: "Some text", preferences: preferences) 130 | tipView.show(forView: someView, withinSuperview: someSuperview) 131 | 132 | // later on you can dismiss it 133 | tipView.dismiss() 134 | ``` 135 | Customizing the appearance 136 | -------------- 137 | In order to customize the `EasyTipView` appearance and behavior, you can play with the `Preferences` structure which encapsulates all the customizable properties of the ``EasyTipView``. These preferences have been split into three structures: 138 | * ```Drawing``` - encapsulates customizable properties specifying how ```EastTipView``` will be drawn on screen. 139 | * ```Positioning``` - encapsulates customizable properties specifying where ```EasyTipView``` will be drawn within its own bounds. 140 | * ```Animating``` - encapsulates customizable properties specifying how ```EasyTipView``` will animate on and off screen. 141 | 142 | | `Drawing ` attribute | Description | 143 | |----------|-------------| 144 | |`cornerRadius`| The corner radius of the tip view bubble.| 145 | |`arrowHeight`| The height of the arrow positioned at the top or bottom of the bubble.| 146 | |`arrowWidth`| The width of the above mentioned arrow.| 147 | |`foregroundColor`| The text color.| 148 | |`backgroundColor`| The background color of the bubble.| 149 | |`arrowPosition`| The position of the arrow. This can be:
**+** `.top`: on top of the bubble
**+** `.bottom`: at the bottom of the bubble.
**+** `.left`: on the left of the bubble
**+** `.right`: on the right of the bubble
**+** `.any`: use this option to let the `EasyTipView` automatically find the best arrow position.
**If the passed in arrow cannot be applied due to layout restrictions, a different arrow position will be automatically assigned.**| 150 | |`textAlignment`| The alignment of the text.| 151 | |`borderWidth`| Width of the optional border to be applied on the bubble.| 152 | |`borderColor`| Color of the optional border to be applied on the bubble. **In order for the border to be applied, `borderColor` needs to be different that `UIColor.clear` and `borderWidth` > 0**| 153 | |`font`| Font to be applied on the text. | 154 | |`shadowColor`| The color of the shadow (default `UIColor.clearcolor`).| 155 | |`shadowOpacity`| The opacity of the shadow (default `0`). **For the shadow to be drawn, both** `shadowColor` **and** `shadowOpacity` **must be set to a valid value.**| 156 | |`shadowRadius`| The radius of the shadow (default `0`).| 157 | |`shadowOffset` | The offset of the shadow. | 158 | 159 | | `Positioning ` attribute | Description | 160 | |----------|-------------| 161 | |`bubbleHInset`| Horizontal bubble inset within its container.| 162 | |`bubbleVInset`| Vertical bubble inset within its container.| 163 | |`contentHInset`| Content horizontal inset within the bubble.| 164 | |`contentVInset`| Content vertical inset within the bubble.| 165 | |`maxWidth`| Max bubble width.| 166 | 167 | | `Animating ` attribute | Description | 168 | |----------|-------------| 169 | |`dismissTransform`| `CGAffineTransform` specifying how the bubble will be dismissed. | 170 | |`showInitialTransform`| `CGAffineTransform` specifying the initial transform to be applied on the bubble before it is animated on screen. | 171 | |`showFinalTransform`| `CGAffineTransform` specifying how the bubble will be animated on screen. | 172 | |`springDamping`| Spring animation damping.| 173 | |`springVelocity`| Spring animation velocity.| 174 | |`showInitialAlpha`|Initial alpha to be applied on the tip view before it is animated on screen.| 175 | |`dismissFinalAlpha`|The alpha to be applied on the tip view when it is animating off screen.| 176 | |`showDuration`|Show animation duration.| 177 | |`dismissDuration`|Dismiss animation duration.| 178 | |`dismissOnTap`|Prevents view from dismissing on tap if it is set to false. (Default value is true.)| 179 | 180 | Customising the presentation or dismissal animations 181 | -------------- 182 | 183 | The default animations for showing or dismissing are scale up and down. If you want to change the default behavior, you need to change the attributes of the ``animating`` property within the preferences. An example could be: 184 | 185 | ```swift 186 | preferences.animating.dismissTransform = CGAffineTransform(translationX: 0, y: -15) 187 | preferences.animating.showInitialTransform = CGAffineTransform(translationX: 0, y: -15) 188 | preferences.animating.showInitialAlpha = 0 189 | preferences.animating.showDuration = 1.5 190 | preferences.animating.dismissDuration = 1.5 191 | ``` 192 | 193 | This produces the following animations: 194 |

195 | 196 | For more animations, checkout the example project. 197 | *Once you configured the animations, a good idea would be to __make these preferences global__, for all future instances of `EasyTipView` by assigning it to ```EasyTipView.globalPreferences```.* 198 | 199 | 200 | License 201 | -------------- 202 | 203 | ```EasyTipView``` is developed by [Teodor Patraş](https://www.teodorpatras.com) and is released under the MIT license.
