Keeping a UIButton selected after a touch

Question

After my user clicks a button, I\'d like that button to stay pushed during the time that I perform a network operation. When the network operation is complete, I want the bu

I have another way ...if you don't want to use images, and you want the effect of a pressed button, You can subclass the Button and here's my code:

in the .h File:

@interface reservasButton : UIButton {

BOOL isPressed;
}
 @end

In the .m File:

#import 


 @implementation reservasButton

 -(void)setupView {  //This is for Shadow

    self.layer.shadowColor = [UIColor blackColor].CGColor;
    self.layer.shadowOpacity = 0.5; 
    self.layer.shadowRadius = 1;    
    self.layer.shadowOffset = CGSizeMake(2.0f, 2.0f); //comment
    //   self.layer.borderWidth = 1;
    self.contentVerticalAlignment   = UIControlContentVerticalAlignmentCenter;
    self.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

    // [self setBackgroundColor:[UIColor whiteColor]];

    //  self.opaque = YES;


}

-(id)initWithFrame:(CGRect)frame{
    if((self = [super initWithFrame:frame])){
        [self setupView];
    }

    return self;
}

-(id)initWithCoder:(NSCoder *)aDecoder{
    if((self = [super initWithCoder:aDecoder])){
        [self setupView];
    }

    return self;
}

//Here is the important code

 -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{


  if (isPressed == FALSE) {

      self.contentEdgeInsets = UIEdgeInsetsMake(1.0,1.0,-1.0,-1.0);
      self.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
      self.layer.shadowOpacity = 0.8;

      [super touchesBegan:touches withEvent:event];

      isPressed = TRUE;

     }
     else {

         self.contentEdgeInsets = UIEdgeInsetsMake(0.0,0.0,0.0,0.0);
         self.layer.shadowOffset = CGSizeMake(2.0f, 2.0f);
         self.layer.shadowOpacity = 0.5;

         [super touchesEnded:touches withEvent:event];

         isPressed = FALSE;

     }
