- [x] Can be shown pointing to any ``UIBarItem`` or ``UIView`` subclass.

- [x] Support for any arrow direction `←, →, ↑, ↓`

- [x] Automatic orientation change adjustments.

- [x] Fully customizable appearance (custom content view or simply just text - including `NSAttributedString` - see the Example app).

- [x] Fully customizable presentation and dismissal animations.



 Installation 

--------------



### CocoaPods



[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects.



CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:



```bash

$ gem install cocoapods

```



To integrate EasyTipView into your Xcode project using CocoaPods, specify it in your `Podfile`:



```ruby

pod 'EasyTipView', '~> 2.1'

```



Then, run the following command:



```bash

$ pod install

```



In case Xcode complains ("Cannot load underlying module for EasyTipView") go to Product and choose Clean (or simply press ⇧⌘K).



### Carthage



[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.



You can install Carthage with [Homebrew](http://brew.sh/) using the following command:



```bash

$ brew update

$ brew install carthage

```



To integrate EasyTipView into your Xcode project using Carthage, specify it in your `Cartfile`:



```ogdl

github "teodorpatras/EasyTipView"

```



Run `carthage update` to build the framework and drag the built `EasyTipView.framework` into your Xcode project.



### Manually



If you prefer not to use either of the aforementioned dependency managers, you can integrate EasyTipView into your project manually.



 Supported OS & SDK Versions 

-----------------------------



* Supported build target - iOS 8+ (Xcode 8)



 Usage 

--------------



1) First you should customize the preferences:

```swift



var preferences = EasyTipView.Preferences()

preferences.drawing.font = UIFont(name: "Futura-Medium", size: 13)!

preferences.drawing.foregroundColor = UIColor.whiteColor()

preferences.drawing.backgroundColor = UIColor(hue:0.46, saturation:0.99, brightness:0.6, alpha:1)

preferences.drawing.arrowPosition = EasyTipView.ArrowPosition.top



/*

 * Optionally you can make these preferences global for all future EasyTipViews

 */

EasyTipView.globalPreferences = preferences



```



2) Secondly call the ``show(animated: forView: withinSuperview: text: preferences: delegate:)`` method:

```swift

EasyTipView.show(forView: self.buttonB,

withinSuperview: self.navigationController?.view,

text: "Tip view inside the navigation controller's view. Tap to dismiss!",

preferences: preferences,

delegate: self)

```



**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**.



*Alternatively, if you want to dismiss the ``EasyTipView`` programmatically later on, you can use one of the instance methods:*



```swift



let tipView = EasyTipView(text: "Some text", preferences: preferences)

tipView.show(forView: someView, withinSuperview: someSuperview)



// later on you can dismiss it

tipView.dismiss()

```

 Customizing the appearance 

--------------

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:

* ```Drawing``` - encapsulates customizable properties specifying how ```EastTipView``` will be drawn on screen.

* ```Positioning``` - encapsulates customizable properties specifying where ```EasyTipView``` will be drawn within its own bounds.

* ```Animating``` - encapsulates customizable properties specifying how ```EasyTipView``` will animate on and off screen.



| `Drawing ` attribute   |      Description      |

|----------|-------------|

|`cornerRadius`| The corner radius of the tip view bubble.|

|`arrowHeight`| The height of the arrow positioned at the top or bottom of the bubble.|

|`arrowWidth`| The width of the above mentioned arrow.|

|`foregroundColor`| The text color.|

|`backgroundColor`| The background color of the bubble.|

|`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.**|

|`textAlignment`| The alignment of the text.|

|`borderWidth`| Width of the optional border to be applied on the bubble.|

|`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**|

|`font`| Font to be applied on the text. |

|`shadowColor`| The color of the shadow (default `UIColor.clearcolor`).|

|`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.**|

|`shadowRadius`| The radius of the shadow (default `0`).|

|`shadowOffset` | The offset of the shadow. |



| `Positioning ` attribute   |      Description      |

|----------|-------------|

|`bubbleHInset`| Horizontal bubble inset within its container.|

|`bubbleVInset`| Vertical bubble inset within its container.|

|`contentHInset`| Content horizontal inset within the bubble.|

|`contentVInset`| Content vertical inset within the bubble.|

|`maxWidth`| Max bubble width.|



| `Animating ` attribute   |      Description      |

|----------|-------------|

|`dismissTransform`| `CGAffineTransform` specifying how the bubble will be dismissed. |

|`showInitialTransform`| `CGAffineTransform` specifying the initial transform to be applied on the bubble before it is animated on screen. |

|`showFinalTransform`| `CGAffineTransform` specifying how the bubble will be animated on screen. |

|`springDamping`| Spring animation damping.|

|`springVelocity`| Spring animation velocity.|

|`showInitialAlpha`|Initial alpha to be applied on the tip view before it is animated on screen.|

|`dismissFinalAlpha`|The alpha to be applied on the tip view when it is animating off screen.|

|`showDuration`|Show animation duration.|

|`dismissDuration`|Dismiss animation duration.|

|`dismissOnTap`|Prevents view from dismissing on tap if it is set to false. (Default value is true.)|



 Customising the presentation or dismissal animations 

--------------



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:



```swift

preferences.animating.dismissTransform = CGAffineTransform(translationX: 0, y: -15)

preferences.animating.showInitialTransform = CGAffineTransform(translationX: 0, y: -15)

preferences.animating.showInitialAlpha = 0

preferences.animating.showDuration = 1.5

preferences.animating.dismissDuration = 1.5

```



This produces the following animations:






For more animations, checkout the example project.

*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```.*
