You should check/require permission before using GMImagePicker. The problem will be gone, draft codes below:

    PHAuthorizationStatus authStatus = [PHPhotoLibrary authorizationStatus];
    
    if (authStatus == PHAuthorizationStatusAuthorized) {
        // Have permission -> Open GMImagePicker
    } 
    else if (authStatus == PHAuthorizationStatusDenied) {
        // No permission > Let user knows s/he should grant permission to continue
    } 
    else {
        [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
            BOOL granted = (status == PHAuthorizationStatusAuthorized);
            dispatch_async(dispatch_get_main_queue(), ^{
                // If Have permission -> Open GMImagePicker
                // Else -> Let user knows s/he should grant permission to continue
            });
        }];
    }

That is indeed what I did, but it is not in my opinion a correct solution for your library : as GMImagePicker handles permission asking, it should also handle the "permission denied" case, because developers would expect that from the lib.
