Allow user to change image to one from their gallery

I have a UIImageView that has a UIImage. What i would like is when the UIImage is clicked the user can select a photo from thier gallery to show in the UIImageView instead of the default image i have set

    imageView = [[UIImageView alloc] init];
    UIImage *myimg = [UIImage imageNamed:@"ProfilePic.png"];
    imageView.image=myimg;
    imageView.frame = CGRectMake(100,0, 80, 50); // pass your frame   here
    [setsView addSubview:imageView];
    imageView.layer.backgroundColor=[[UIColor clearColor] CGColor];
    imageView.layer.cornerRadius=20;
    imageView.layer.borderWidth=2.0;
    imageView.layer.masksToBounds = YES;
    imageView.layer.borderColor=[[UIColor redColor] CGColor];

EDIT: If I could make a view with a bunch of images and when an image is clicked it changes the "myimg" to the clicked image if that makes sense

EDIT #2:Also how would u save the photo the user chose and use it the next time the user opened the appliation

What you need is to implement UIImagePickerController with UIImagePickerControllerSourceTypePhotoLibrary as a source type.\n\nThere´re tons of tutorials and questions/answers here in stackoverflow. \n\nCheck for example this thread. It has pretty good answers with reference links to a sample code from Apple and other interesting tutorials. \n\nEDIT #2:\nWell, this also has many ways to be accomplished all depends on your use case. But a quick and simple way to do it is by using NSUserDefaults.\n\nEg:\nThis to save the image,\n\nNSData * data = UIImagePNGRepresentation(yourUImage);\nNSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];\n[defaults setObject:data forKey:@\"userImage\"];\n[defaults synchronize];\n\n\nand to get the image\n\n- (void)viewDidLoad \n{\n [super viewDidLoad];\n\n NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];\n NSData *data = [defaults objectForKey:@\"userImage\"];\n UIImage *image = [UIImage imageWithData:data];\n\n yourImageView.image = image;\n}\n",
