Select an image from Gallery and show it in an ImageView in ios.

Hey all,

This is a simple post showing how you can open the “Gallery” or “Photos” application in iOS.

ViewController.m

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UINavigationControllerDelegate,
UIImagePickerControllerDelegate>


@property (strong, nonatomic) IBOutlet UIImageView* imageView;

- (IBAction) pickImage:(id)sender;


@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
}

- (IBAction) pickImage:(id)sender{
    
    UIImagePickerController *pickerController = [[UIImagePickerController alloc]
                                                 init];
    pickerController.delegate = self;
    [self presentViewController:pickerController animated:YES completion:nil];
}

#pragma mark -
#pragma mark UIImagePickerControllerDelegate

- (void) imagePickerController:(UIImagePickerController *)picker
         didFinishPickingImage:(UIImage *)image
                   editingInfo:(NSDictionary *)editingInfo
{
    self.imageView.image = image;
    [self dismissModalViewControllerAnimated:YES];
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

@end

We add “UINavigationControllerDelegate,UIImagePickerControllerDelegate” to get the events after selecting the image from
the Gallery.

The below function is called after selecting image from Gallery

– (void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
