Lỗi khi tải quảng cáo
Sử dụng bộ sưu tập để sắp xếp ngăn nắp các trang
Lưu và phân loại nội dung dựa trên lựa chọn ưu tiên của bạn.
Trong trường hợp quảng cáo không tải được, hệ thống sẽ gọi một phương thức uỷ quyền hoặc trình xử lý hoàn thành để cung cấp một đối tượng NSError
.
Đối với GADBannerView
, lệnh gọi lại là:
Ví dụ sau đây cho thấy thông tin có sẵn khi quảng cáo không tải được:
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 = (error as NSError).userInfo[NSUnderlyingErrorKey] as? Error
if let responseInfo = responseInfo {
print("Received error with domain: \(errorDomain), code: \(errorCode),"
+ "message: \(errorMessage), responseInfo: \(responseInfo),"
+ "underlyingError: \(underlyingError?.localizedDescription ?? "nil")")
}
}
Objective-C

NSString *errorDomain = error.domain;
// Gets the error code. See

int errorCode = error.code;
// Gets an error message.

GADResponseInfo *responseInfo = error.userInfo[GADErrorUserInfoKeyResponseInfo];
// Gets the underlyingError, if available.
NSError *underlyingError = error.userInfo[NSUnderlyingErrorKey];
NSLog(@"Received error with domain: %@, code: %ld, message: %@, "
@"responseInfo: %@, underlyingError: %@",
errorDomain, errorCode, errorMessage, responseInfo,
underlyingError.localizedDescription);
}
