How to find IMEI and IMSI id in iPhone?

UIDevice *device=[UIDevice cu开发者_如何学Pythonrrentdevice];  
NSString *ss=[NSString stringWithFormate:"%@",[device currentdevice].uniqueidentifier;

But I don't know how to find IMEI and IMSI id programatically, any one have an idea please help to me.

There's no public API for this.

It's possible using IOKit, but that's not a documented API on iOS, so you can't use it for App Store apps.
