ios - Making an Image Picker with UIButton in Swift -

i make image picker uibutton pointing imagepickerview don't know how proceed.

we'll want connect viewcontroller "a" (with uibutton) viewcontroller "b" (uiimagepicker).

this tried : have storyboard multiples viewcontroller, , don't know why can't make ibaction viewcontroller "a" viewcontroller "b".

should make imagepickerview programatically or can use storyboard?

thanks in advance !

uiimagepickercontroller can't added in storyboard, must programmatically. first, create ibaction uibutton:

- (ibaction)openimagepicker:(id)sender; 

your class need adopt uiimagepickercontrollerdelegate , uinavigationcontrollerdelegate protocol:

@interface myviewcontroller () <uiimagepickercontrollerdelegate, uinavigationcontrollerdelegate> 

then show image picker in openimagepicker: method:

// check if image source available // in case, photo library available. if use // uiimagepickercontrollersourcetypecamera instead, simulator doesn't have if ([uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypephotolibrary]) {      uiimagepickercontroller *picker = [[uiimagepickercontroller alloc] init]; // create image picker     picker.sourcetype = uiimagepickercontrollersourcetypephotolibrary; // choose source type     picker.delegate = self; // delegate when image picked     picker.allowsediting = yes; // allow user edit image before choose     [self presentviewcontroller:picker animated:yes completion:nil]; // show image picker } 

to use picked image, must implement method of uiimagepickercontrollerdelegate:

/**  * @param picker image picker  * @param info dictionary contains picked images , metadata...  */ - (void)imagepickercontroller:(nonnull uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nonnull nsdictionary *)info {     // because allow user edit image,     // choose uiimagepickercontrollereditedimage     // can see other keys in uiimagepickercontroller class header     uiimage *editedimage = [info objectforkey:uiimagepickercontrollereditedimage];      // dismiss picker     dispatch_async(dispatch_get_main_queue(), ^{         [self dismissviewcontrolleranimated:yes completion:nil];     });      // use image here }
