(WITH SINGLE BUTTON WITHOUT USE SUBVIEW) CREATE IMAGE ON IMAGE EDITING FROM THE LIBRARY

STEP 1

WRITE IT IN TO "ViewController.h"

#import <UIKit/UIKit.h>

#import "ZDStickerView.h"

@interface ViewController : UIViewController<ZDStickerViewDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate>

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

@property (strong, nonatomic) IBOutlet UIButton *btnImage2;

@end

STEP 2

WRITE IT IN TO "ViewController.m"

#import "ViewController.h"

@interface ViewController ()

{

    ZDStickerView *userResizableView1;

}

@end

@implementation ViewController

- (void)viewDidLoad

{

    [super viewDidLoad];

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

    imgPicker.delegate = self;

    imgPicker.allowsEditing = YES;

    imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    

    [self presentViewController:imgPicker animated:YES completion:NULL];

}

{

    UIImage *imgChosen = info[UIImagePickerControllerEditedImage];

    CGRect gripFrame1 = CGRectMake(90, 50, 100, 100);

    UIImageView *imageView1 = [[UIImageView alloc] initWithImage:imgChosen];

    UIView* contentView = [[UIView alloc] initWithFrame:gripFrame1];

    [contentView addSubview:imageView1];

    [self.view addSubview:userResizableView1];

    [self dismissViewControllerAnimated:YES completion:nil];

}

- (IBAction)btnDone:(id)sender

{

                {

                }

            }

        }

    }

    UIGraphicsBeginImageContext(self.view.bounds.size);

    // retrieve the current graphics context

    CGContextRef context = UIGraphicsGetCurrentContext();

    UIGraphicsEndImageContext();
