Debug url saving for art object on davaz.com

Debug video url saving.
Again, only production has this problem. (In my VM, It works fine.)

z.B.

Note

This Cause was "Serie Position" field.
It's essential(require) field.

"Serie Position" was empty.

Problem no model in view

I found no model error in production log.
Then I updated to prevent this error. (I don't know Why this is solution. But it's oddb.org's way.)

This error happened sometimes. (not always)
And view output does not have any problem, although it has this error.

But I prevent this error.

Solution is: 

def url(model)
  text = model.url #=> undefined method `url' for nil:NilClass (why?)
  ...
end

def url(model=@model)
  text = model.url #=> it works
  ...
end

Hack zbar toolbal in iPad (on iOS 7)

ZBarReaderViewController extends UIViewController. 


@interface ZBarReaderViewController
    : UIViewController
{
    ZBarImageScanner *scanner;
    id <ZBarReaderDelegate> readerDelegate;
    ZBarReaderView *readerView;
    UIView *cameraOverlayView;
    CGAffineTransform cameraView
    ...

Check subviews of ZBarReaderViewController#view 

DLog(@"subviews #=> %@", self.reader.view.subviews);
# DLog(@"subview with index 1 #=> %@", [self.reader.view.subviews objectAtIndexPath:1]);

2013-08-21 16:31:43.684 generika[5285:a0b] -[MasterViewController openReader] [Line 381] reader.view's subviews #=> (
    "<ZBarReaderViewImpl: 0xa190790; frame = (0 0; 320 426); clipsToBounds = YES; autoresize = W+H+BM; gestureRecognizers = <NSArray: 0xa187540>; layer = <CALayer: 0xa186920>>",
    "<UIView: 0xa19deb0; frame = (0 426; 320 54); autoresize = W+TM+H; layer = <CALayer: 0xa19c910>>"
)

I found toolbar! this UIView has UIToolbar.
check it like this: 

UIView *thisIsBarOwner = [self.reader.view.subviews objectAtIndexPath:1];
[thisIsBarOwner removeFromSuperview];  #=> toolbar is gone.

Note

ZBarReaderViewController does not have toolbar, directly.
It use custom uiview It has UIToolbar.

Tried

agaist strange "Cancel" button position.

  • setBackButtonTitlePositionAdjustment:forBarMetrics: ---> NG
  • setBackgroundVerticalPositionAdjustment:forBarMetrics: ---> NG
  • setTitlePositionAdjustment:forBarMetrics: ---> NG
  • setBackButtonBackgroundVerticalPositionAdjustment:forBarMetrics: ---> NG

This is strange ...

Then checked subviews of toolbar. 

2013-08-22 02:05:29.919 generika[7977:a0b] -[MasterViewController layoutReaderToolbar] [Line 438] subviews (
    "<_UIToolbarBackground: 0x96a0110; frame = (0 0; 320 598); autoresize = W; userInteractionEnabled = NO; layer = <CALayer: 0x96a01b0>>",
    "<UIImageView: 0x969cc50; frame = (0 -1; 320 1); autoresize = W+BM; userInteractionEnabled = NO; layer = <CALayer: 0x969ec40>>",
    "<UIToolbarTextButton: 0x96e4370; frame = (16 0; 54 54); opaque = NO; layer = <CALayer: 0x96f0220>>",
    "<UIButton: 0x96dcf90; frame = (278 16; 22 22); opaque = NO; layer = <CALayer: 0x96e7fa0>>"
)

Finaly, I update "Cancel" Button position.
This is not perfect. (It moves in delay)

But there is no way without implementation file of ZBar.
