Question

-(void)cameraAndPhotoAlbums{
self.actionSheet = [[UIActionSheet alloc] initWithTitle:#"title" delegate:self cancelButtonTitle:#"cancel" destructiveButtonTitle:nil otherButtonTitles:#"Photo album",#"camera", nil];
[self.actionSheet showInView:self.view];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex==0) {
UIImagePickerController * imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:YES completion:nil];
} else if(buttonIndex==1) {
UIImagePickerController * imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imagePicker animated:YES completion:nil];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
[picker dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerControllerDidCancel:(id)picker{
[picker dismissViewControllerAnimated:YES completion:nil];
}
But at the time of photo album selected photos will only perform the cancel but finish don't perform, tried this item anywhere to write all can't, I again open a project can go agent, a great god save stunned me..

Here is a sample code for you to study:
ViewController.h
#interface ViewController : UIViewController<UIImagePickerControllerDelegate>
{
UIImagePickerController * imagePicker;
}
#property (strong, nonatomic) IBOutlet UIImageView *imageView;
- (IBAction)setImageToImageView:(UIButton *)sender;
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSLog(#"%#",NSHomeDirectory());
imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Image Picker Delegate
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
{
NSLog(#"Image picked");
self.imageView.image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
if (picker.sourceType == UIImagePickerControllerSourceTypePhotoLibrary)
{
NSData * data = UIImageJPEGRepresentation([info valueForKey:#"UIImagePickerControllerOriginalImage"], 0.5);
NSString * path = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/image.JPEG"];
[data writeToFile:path atomically:true];
}
else
{
UIImageWriteToSavedPhotosAlbum([info valueForKey:#"UIImagePickerControllerOriginalImage"], nil, nil, nil);
}
[self dismissViewControllerAnimated:true completion:nil];
}
- (IBAction)setImageToImageView:(UIButton *)sender
{
if (sender.tag == 101)
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
else
{
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentViewController:imagePicker animated:true completion:nil];
}
#end
This code works, tested it on a device.
