Answer 1

Solved doing this: in the viewdidload

readerqr = [ZBarReaderViewController new];
    readerqr.readerDelegate = self;
    readerqr.showsHelpOnFail = NO;

ZBarImageScanner *scanner = readerqr.scanner;
[scanner setSymbology: 0
               config: ZBAR_CFG_ENABLE
                   to: 0];
[scanner setSymbology: ZBAR_QRCODE
               config: ZBAR_CFG_ENABLE
                   to: 1];

// you can use this to support the simulator
if(TARGET_IPHONE_SIMULATOR) {
    cameraSim = [[ZBarCameraSimulator alloc]
                 initWithViewController: self];
    cameraSim.readerView = readerView;
}

create ZBarReaderViewController *readerqr; as a property of your viewcontroller.

to use it:

-(void) showqr:(id)sender
{
    [self presentViewController:readerqr animated:YES completion:nil];
    return;
}

This way works, no leak, no cpu 100%
