Unrecognized selector error when upgrading iOS Google Mobile Ads SDK to 7.39 from 7.16

[Alonso Alvarez]

I have a CustomView that is a Subclass of DFPBannerView.

@interface CustomView : DFPBannerView <AdObject, GADBannerViewDelegate>

CustomView has this initializer:

- (id)initWithAdSize:(GADAdSize)size pos:(NSString *)pos

{

    if (self = [super initWithAdSize:size]) {

        _pos = pos;

        _size = size;

        _visible = YES;

        _obscured = NO;

       self.delegate = self;

   }

   return self;

}

Before upgrading to the last version (I was using 7.16) everything was working fine. Now im getting this error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CustomView initWithAdSize:]: unrecognized selector sent to instance 0x7ffd55c89740'

Which is called on this line:

if (self = [super initWithAdSize:size]) {

Does anyone has any idea why this is happening? DFPBannerView is a subclass of GADBannerView which have that initializer:

@interface GADBannerView : UIView

#pragma mark Initialization

/// Initializes and returns a banner view with the specified ad size and origin relative to the

/// banner's superview.

- (instancetype)initWithAdSize:(GADAdSize)adSize origin:(CGPoint)origin;

/// Initializes and returns a banner view with the specified ad size placed at its superview's

/// origin.

- (instancetype)initWithAdSize:(GADAdSize)adSize;

Hello there,

Thanks for reaching out to us. Can you please share the complete device logs for us to take a look? Is the app getting crashed or you were just not able to load ad? Can you please add more details about the Ad types and confirm whether you were able to reproduce the issue with our sample apps?

Hi, thanks for your response. I was able to reproduce my crash on the sample apps in Swift. I created a Customview class that is a DFPBannerView Subclass on BannerTableViewExample.

class CustomView: DFPBannerView {

 

     

    var pos: String

     

    init(size: GADAdSize, pos: String) {

        self.pos = pos

        super.init(adSize: size)

    }

     

    required init?(coder aDecoder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }

     

}

When I try to initialize CustomView

let customView = CustomView(size: kGADAdSizeBanner, pos: "L")

 I get the following:

My guess is that we are not able to subclass DFPBannerView anymore. Is that true or am I doing something wrong? Thanks for your time.

Hello there,

Yes this is true that you can no longer subclass DFPBannerView. 

Let us know if you need anything else.
