Hide Multiple UIButton in single button click

I have 5 buttons in my xib, Button 1 to 4 is mapped to 

-(IBAction)btn1to4:(UIButton *)sender;

Button 5 is mapped to 

-(IBAction)btnFive:(id)sender;

Initially all the 4 buttons are hidden and only button 5 is visible, What I need is when I click on Button 5 all the 4 buttons should appear and when I click again on Button 5 they should disappear. For individual button I can write code in Button 5 as button1.hidden=NO, button2.hidden=NO and soon. But my buttons 1 to 4 are mapped to single btn1to4 method. How should I code in my btnFive method to hide/Unhide all 4 buttons at once?

In your -(IBAction)btnFive:(id)sender, first check any one button (from 1-4) hidden property & do its opposite in condition. please find sample below - 

-(IBAction)btnFive:(id)sender {    
if(btn4.hidden==false){
          btn1.hidden=true;
          btn2.hidden=true;
          btn3.hidden=true;
          btn5.hidden=true;
    }else{
         btn1.hidden=false;
         btn2.hidden=false;
         btn3.hidden=false;
         btn5.hidden=false;
    }
}

try to write less number of line code and try to write effective lines.

in your .h file

int a;

.m

-(void)viewDidLoad
{
 a=0;
}

In your button click

-(IBAction)btnFive:(id)sender


{
    if(a==0)
    {
      button1.hidden = YES;
      button2.hidden = YES;
      button3.hidden = YES;
      button4.hidden = YES;
      a = 1;

    }
    else
    {
      button1.hidden = NO;
      button2.hidden = NO;
      button3.hidden = NO;
      button4.hidden = NO;
      a = 0;
    }
}

Add buttons 1 through 4 to an IBOutletCollection in the interface builder. Add a property

@property (nonatomic, strong) IBOutletCollection(UIButton) NSArray *buttons1_4;

and drag buttons 1..4 there. Here is an answer explaining how to do it step-by-step.

Now you can operate all the buttons in that collection using a loop, rather than referencing them individually:

-(void)flipButtonsVisibility:(UIButton*)sender {
    for (UIButton *btn in buttons1_4) {
        btn.hidden = !btn.hidden;
    }
}

Give tag of your button5 such like 

button5.tag = 101;

In you button5's IBAction change id to UIButton * in parameter, such like 

-(IBAction)btnFive:(UIButton *)sender

And Write following code

-(IBAction)btnFive:(UIButton *)sender
{
    if(sender.tag == 101)
    {
      self.btn1.hidden = YES;
      self.btn2.hidden = YES;
      self.btn3.hidden = YES;
      self.btn4.hidden = YES;
      sender.tag = 102;
    }
    else
    {
      self.btn1.hidden = NO;
      self.btn2.hidden = NO;
      self.btn3.hidden = NO;
      self.btn4.hidden = NO;

      sender.tag = 101;
    }
}
