Question

Basically I want to remove my subview when a button is pressed, here is my code, please tell me what should I add.

I have created a view based application and following are the codes:

//My file name is poo1

//This is poo1ViewController.h file

#import <UIKit/UIKit.h>
@interface poo1ViewController : UIViewController 
{
 IBOutlet UIButton *fl;
}
@property (nonatomic,retain) UIButton *fl;
-(IBAction) ifl:(id)sender;    
@end

This is poo1ViewController.m file

    #import "poo1ViewController.h"
    @implementation poo1ViewController
    @synthesize fl;
    -(IBAction) ifl:(id) sender {
    UIViewController* flipViewController = [[UIViewController alloc] initWithNibName:@"flip" bundle:[NSBundle mainBundle]];
    [self.view addSubview:flipViewController.view];
    }

Now similarly I have added a UIViewController Subclass called “flip” with xib. And in flip.h I have added the below code

#import <UIKit/UIKit.h>
@interface flip : UIViewController 
{
    IBOutlet UIButton *bb;
}
@property (nonatomic,retain)UIButton *bb;
-(IBAction)ss:(id)sender;
@end

And in flip.m

#import "flip.h"
@implementation flip
@synthesize bb;

-(IBAction)ss:(id)sender
{
 //What do I need to add here to return to previous view when button is pressed.
}

When this bb button is pressed, it should act as back button, how to implement it.

Answer 1

just add [self removeFromSuperview]; to your method ss:
Note however that this does not dealloc the view from the memory. It’s just not showing!
