IPhone: Use uiimagepickercontroller to retrieve images from the iPhone photo library or camera

From: Use uiimagepickercontroller to retrieve images from the iPhone photo library or camera

Using uiimagepickercontroller to select a photo library is very simple:

In the corresponding response:

Uiimagepickercontroller * picker = [[uiimagepickercontroller alloc] init];

Picker. Delegate = self; // The controller must follow the response's delegate protocol of course.

Picker.Sourcetype=Uiimagepickercontrollersourcetypephotolibrary;// Specify picker resources. There are three types:

// Enum {uiimagepickercontrollersourcetypephotolibrary,

// Uiimagepickercontrollersourcetypecamera,

// Uiimagepickercontrollersourcetypesavedphotosalbum}

[SelfPresentmodalviewcontroller: PickerAnimated:Yes];// Display the picker View

 

In the delegate method:

-(Void) Imagepickercontroller :(Uiimagepickercontroller*) Picker didfinishpickingmediawithinfo :(Nsdictionary*) Info {

//Info: A dictionary containing the original image and the edited image, if an image was picked; or a filesystem URL for the movie, if a movie was picked

[PickerDismissmodalviewcontrolleranimated:Yes]; // Disappear

Imageview.Image= [InfoObjectforkey:@ "Uiimagepickercontrolleroriginalimage"];

}

 

 
Nsstring * const uiimagepickercontrollermediatype; nsstring * const region; nsstring * const uiimagepickercontrollercroprect; nsstring * const region;

Using assetslibrary framework loading images too slow

 

supplement: The iPad cannot call up uiimagepickercontroller. You need to call it through popover.
