(WITH DOUBLE 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>

{

    UIImagePickerController *imgpkr;

}

- (IBAction)btnAdd:(id)sender;

- (IBAction)btnDone:(id)sender;

- (IBAction)btnImage2:(id)sender;

@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 ()

    BOOL ImgViewEnable;

}

@end
