I have added a new service in the BLE device, It is getting on the android device, but not on the iOS device. I don't know why this happening. please help if anyone knows.
No there is nothing like limitations for BLE in IOS.
here you mention that it works in android it means your BLE service is Working properly.
I think the problem is in your service calling (your ios code to use service) so please check it again.
