-
When an ad fails to load, a delegate method or completion handler is called providing an
NSErrorobject. -
The
NSErrorobject contains information such as the error domain, code, and a localized description. -
For errors in the
GADErrorDomain, thelocalizedDescriptioncan provide a more detailed explanation and suggest actions for resolution.
In cases where an ad fails to load, a
delegate method or completion handler
is called which provides a NSError
object.
For GADBannerView
, the following is called:
Swift
func
bannerView
(
_
bannerView
:
BannerView
,
didFailToReceiveAdWithError
error
:
Error
)
Objective-C
-
(
void
)
bannerView:
(
nonnull
GADBannerView
*
)
bannerView
didFailToReceiveAdWithError
:(
nonnull
NSError
*
)
error
;
The following example shows the information available when an ad fails to load:
Swift
func
bannerView
(
_
bannerView
:
BannerView
,
didFailToReceiveAdWithError
error
:
Error
)
{
// Gets the domain from which the error came.
let
errorDomain
=
error
.
domain
// Gets the error code. See
// https://developers.google.com/admob/ios/api/reference/Enums/GADErrorCode
// for a list of possible codes.
let
errorCode
=
error
.
code
// Gets an error message.
// For example "Account not approved yet". See
// https://support.google.com/admob/answer/9905175 for explanations of
// common errors.
let
errorMessage
=
error
.
localizedDescription
// Gets additional response information about the request. See
// https://developers.google.com/admob/ios/response-info for more information.
let
responseInfo
=
(
error
as
NSError
).
userInfo
[
GADErrorUserInfoKeyResponseInfo
]
as

ResponseInfo
// Gets the underlyingError, if available.
let
underlyingError

let
responseInfo
