I have one UIButton(lets say instance1).I have set target method when it moves.So when I try to move(drag) I want to do that create copy of instance1 and that copy button should be moved(dragged).Yes I know that -copy will not support to UIButton.So I used :

NSData *archivedData = [NSKeyedArchiver archivedDataWithRootObject: sender];
UIButton *buttonCopy = [NSKeyedUnarchiver unarchiveObjectWithData: archivedData];

But the problem is when I am trying to move copy button,its not moving and on second attempt it is hiding/removing from screen.Please help me.

ios objective-c uibutton nsdata

try to create a "copy constructor". create a new button with alloc init, then set it's properties one by one after the source button.                 –                      Calin Chitu                 Oct 8 '13 at 7:23                                                                                                 

Try to make a custom buttom class with copyWithZone and use it...                 –                      Javier Peigneux                 Oct 8 '13 at 7:30                                                                            

you should also show the code you use to move it around                 –                      micantox                 Oct 8 '13 at 8:02                                                                            

@JavierPeigneux : to use copyWithZone , i need to create subclass of UIButton.Can we make subclass of UIButton?                 –                      h999                 Oct 8 '13 at 9:56                                                                            

@h999 Of course, you can. I don't know if it is the best way but it is an option.                 –                      Javier Peigneux                 Oct 8 '13 at 13:20

Your example button is self.exampleButton... -(UIButton*)_copie { NSData *arch = [NSKeyedArchiver archivedDataWithRootObject: self.exampleButton]; UIButton *nu = [NSKeyedUnarchiver unarchiveObjectWithData: arch]; [self.view addSubview:nu]; nu.frame = self.exampleButton.frame; [nu addTarget:self action:@selector(oneLinkClicked:) forControlEvents:UIControlEventTouchUpInside]; return nu; } here's an example of making a number of the buttons, in a vertical column. in the example the data comes from a Dictionary... CGPoint zero = self.exampleButton.center; CGFloat gap = self.exampleButton.bounds.size.height * 1.25; NSInteger kount=0; self.orderedLinks = [[NSMutableArray alloc] init]; for ( NSDictionary *link in self.arrayOfLinks ) { NSLog( @"one title... %@", link[@"title"] ); NSLog( @"one url... %@", link[@"url"] ); UIButton *copy = [self _copie]; CGPoint newpos = zero; newpos.y = newpos.y + ( kount * gap ); copy.center = newpos; [copy setTitle:link[@"title"] forState:UIControlStateNormal]; copy.tag = kount; [self.orderedLinks addObject:link[@"url"]]; kount++; } [self.exampleButton removeFromSuperview]; and when a button is clicked... -(IBAction)oneLinkClicked:(UIButton *)sender { NSLog(@"this tag clicked ...... %ld", (long)sender.tag); NSString *goUrl = self.orderedLinks[ sender.tag ]; NSLog(@"goUrl ...... %@", goUrl ); } share|improve this answer
