联系人的图像没有获取

Question

I am using this code to fetch contact image from device but its not printing any output.

if contact.isKeyAvailable(CNContactImageDataKey) {
    if let contactImageData = contact.thumbnailImageData {
        print("image \(String(describing: UIImage(data: contactImageData)))")
    } else {
        print("No image available")
    }
} else {
    print("No Key image available")
}

but it is printing only "No Key image available" though some of my contacts have images . i tried imageData instead of thumbnailImageData but showing same results.

Answer 1

Make sure CNContactImageDataAvailableKey and CNContactThumbnailImageDataKey is contained in your keysToFetch and remove the isKeyAvailable if clause:

if let imageData = contact.thumbnailImageData {
    print("image \(String(describing: UIImage(data: imageData)))")
} else {
    print("No image available")
}

Answer 2

Add Keys to your fetch request (image keys missing)

 let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactImageDataAvailableKey, CNContactThumbnailImageDataKey]
 let request = CNContactFetchRequest(keysToFetch: keys as [CNKeyDescriptor])
