swift2.0 Uiimagepickercontroller Photo Album video

System ios9.1
Language swift2.0

The most common feature in the app is multimedia selection, first we Storyboard create a button to trigger the selection event

@IBAction func selectImageAction(sender: AnyObject) {}

It usually pops up with a actionsheet with photos, albums, videos and cancellations. IOS 8 Actionsheet and Alertview are unified with the Uialertcontroller method call, 8.3 before the Actionsheet have a separate method was later discarded. First we want to join Actionsheet related delegate as follows

class ViewController: UIViewController ,UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIActionSheetDelegate {}

@IBAction func selectimageaction (sender:anyobject) {Let Actionsheetcontroller:uialertcontroller = Uialertcontrolle R (Title:"Please select", Message:nil, Preferredstyle:. Actionsheet)//Cancel button Let Cancelaction:uialertaction = Uialertaction (title:"Cancel", Style:. Cancel) {action-a VoidIn//just dismiss the action sheet} actionsheetcontroller. Addaction (cancelaction)//Photo Let takepictureaction:uialertaction = uialertaction (title:"Take pictures", style:. Default) {action, Voidin [Self. Initwithimagepickview ("Photo")]} Actionsheetcontroller. Addaction (Takepictureaction)//album Select Let Choosepictureaction:uialertaction = Uialertaction (title: "album", Style: in [self  "album")]} actionsheetcontroller" camera ", Style: in [self  "Camera")]} actionsheetcontroller.presentviewcontroller (ActionSheetController, Animated:true, Completion:nil)}            

So we want the actionsheet created to complete
Look closely at the code above and you will find [self. Initwithimagepickview ("Take photos")]
This function, I choose imagepicker different parameters through this function
First create a var imagepicker:uiimagepickercontroller! Object
Then implement the relevant methods

Func Initwithimagepickview (type:nsstring) {self. Imagepicker = Uiimagepickercontroller () Self. imagepicker. Delegate = Self; Self. imagepicker. Allowsediting = True; Switch type{case"Take pictures": Self. imagepicker. sourcetype =. CameraBreak case"Album": Self. imagepicker. sourcetype =break case  "video": Self .imagepicker.sourcetype = .imagepicker.videomaximumduration = Span class= "Hljs-number" >60 * 3 self.imagePicker.videoquality = .imagepicker.mediaTypes = [String (Kuttypemovie)] break default:print ( "error")} Presentviewcontroller (self< Span class= "Hljs-preprocessor" >.imagepicker, Animated:true, Completion:nil)}      

Swift can support strings, you can also try other types to see! Some methods are basically the same as Object C

The following implementation of the Imagepick delegate method is possible
As follows
Yes, if you want to introduce the recording video function, don't forget to add
Mobilecoreservices.framework Library and import mobilecoreservices header files

Func Imagepickercontroller (Picker:uiimagepickercontroller, didfinishpickingmediawithinfo info: [String:anyobject]) {

        Let mediatype = Info[uiimagepickercontrollermediatype]as! StringLet Compareresult = cfstringcompare (mediatypeAs nsstring!, Kuttypemovie, cfstringcompareflags.comparecaseinsensitive)//interpretation is video or picture if compareresult = Cfcomparisonresult.compareequalto {let Moviepath = Info[uiimagepickercontrollermediaurl ] as? Nsurl //Get path let moviepathstring = moviepath!. RelativePath if uivideoatpathiscompatiblewithsavedphotosalbum (moviePathString!) {Uisavevideoatpathtosavedphotosalbum (moviepathstring!, nil, nil, nil)} print ( "video")} else {print ( "picture") let image = info[ Uiimagepickercontrolleroriginalimage] as? UIImage self.imageView.image = image; } imagepicker.dismissviewcontrolleranimated (true, Completion:nil)}   

Such a multimedia selection function is basically realized!
