IOS 8 Objective c UIBarButtonItem action doesnt work - objective-c

Question

Im using UIBarButtonItem action and it works on ios 7 and not on ios 8
In ios 7 after clicking on the button the method cancelButtonPressed (which defined in action) is running but in ios8 nothing happend the cancelButtonPressed method doesnt called.
id cancelButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelButtonPressed:)
];
Im using it in barcode scanner plugin, it is open the camera and in that screen i have the cancel button:
- (UIView*)buildOverlayView {
if ( nil != self.alternateXib )
{
return [self buildOverlayViewFromXib];
}
CGRect bounds = self.view.bounds;
bounds = CGRectMake(0, 0, bounds.size.width, bounds.size.height);
UIView* overlayView = [[[UIView alloc] initWithFrame:bounds] autorelease];
overlayView.autoresizesSubviews = YES;
overlayView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
overlayView.opaque = NO;
UIToolbar* toolbar = [[[UIToolbar alloc] init] autorelease];
toolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
id cancelButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelButtonPressed:)
];
//self.navigationItem.rightBarButtonItem=cancelButton;
id flexSpace = [[[UIBarButtonItem alloc] autorelease]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil
];
#if USE_SHUTTER
id shutterButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:(id)self
action:#selector(shutterButtonPressed)
];
toolbar.items = [NSArray arrayWithObjects:flexSpace,cancelButton,flexSpace,shutterButton,nil];
#else
toolbar.items = [NSArray arrayWithObjects:flexSpace,cancelButton,flexSpace,nil];
#endif
bounds = overlayView.bounds;
[toolbar sizeToFit];
CGFloat toolbarHeight = [toolbar frame].size.height;
CGFloat rootViewHeight = CGRectGetHeight(bounds);
CGFloat rootViewWidth = CGRectGetWidth(bounds);
CGRect rectArea = CGRectMake(0, rootViewHeight - toolbarHeight, rootViewWidth, toolbarHeight);
[toolbar setFrame:rectArea];
[overlayView addSubview: toolbar];
UIImage* reticleImage = [self buildReticleImage];
UIView* reticleView = [[[UIImageView alloc] initWithImage: reticleImage] autorelease];
CGFloat minAxis = MIN(rootViewHeight, rootViewWidth);
rectArea = CGRectMake(
0.5 * (rootViewWidth - minAxis),
0.5 * (rootViewHeight - minAxis),
minAxis,
minAxis
);
[reticleView setFrame:rectArea];
reticleView.opaque = NO;
reticleView.contentMode = UIViewContentModeScaleAspectFit;
reticleView.autoresizingMask = 0
| UIViewAutoresizingFlexibleLeftMargin
| UIViewAutoresizingFlexibleRightMargin
| UIViewAutoresizingFlexibleTopMargin
| UIViewAutoresizingFlexibleBottomMargin
;
[overlayView addSubview: reticleView];
return overlayView;
}
what is the alternative way for using it on ios8?

Answer 1

remove autorelease and initialize bar button like that
id cancelButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelButtonPressed:)
];
self.navigationItem.rightBarButtonItem=cancelButton;

Answer 2

You might want to make a global variable in class defination or a property for cancelButton instead of using local variable. I guess arc is removing cancelButton from memory.
