IOS gets video and local resources

When uploading files, we select from the local device or use a camera to photograph the files.

Upload button, click the event

 1 - (Ibaction) btnclick {  2 Uiactionsheet * actionsheet = [[Uiactionsheet alloc]  3 Initwithtitle: @"  Select File Source  "  4                                                       Delegate  : Self  5 Cancelbuttontitle:@"  Cancel  "  6   Destructivebuttontitle: Nil  7 Otherbuttontitles: @"  Camera  " , @"  Camera  " , @"  Local album  " ,@"  Local Video  "  , Nil];  8   [Actionsheet showinview: Self. View];  9   [Actionsheet release];  10 }

After you click the button to trigger the btnclick event, the following selection basket will pop up:

The delegate is implemented for uiactionsheet.

After implementing the uiactionsheet delegate, we need to find that we use uiimagepickercontroller. This class will help us select files and open the corresponding selection method. For example, when the buttonindex is 0, it will help us open the camera, we can use the camera to take a photo as the upload of the selected file. Therefore, we need to implement the uiimagepickercontroller delegate here:

 1   # Pragma Mark- 2   # Pragma Uiimagepickercontroller delegate 3 -( Void ) Imagepickercontroller :( uiimagepickercontroller *) picker didfinishpickingmediawithinfo :( nsdictionary * ) Info 4   {  5       If ([[Info objectforkey: uiimagepickercontrollermediatype] isw.tostring :( nsstring * ) Kuttypeimage]) {  6 Uiimage * IMG = [Info objectforkey: uiimagepickercontrollereditedimage];  7 Self. filedata = uiimagejpegrepresentation (IMG, 1.0  );  8 } Else   If ([[Info objectforkey: uiimagepickercontrollermediatype] isw.tostring :( nsstring * ) Kuttypemovie]) {  9 Nsstring * videopath = [[Info objectforkey: uiimagepickercontrollermediaurl] path];  10 Self. filedata = [Nsdata datawithcontentsoffile: videopath];  11   }  12   [Picker dismissmodalviewcontrolleranimated: Yes];  13   }  14  15 -( Void ) Imagepickercontrollerdidcancel :( uiimagepickercontroller * ) Picker  16   {  17   [Picker dismissmodalviewcontrolleranimated: Yes];  18 }

Then, the selected file is saved in filedata. You can call it at any time.
