Well, if he's "juggling" you, you're not reacting correctly when you're getting hit into the air. You're probably trying to land on him with an aerial or something. Just find a safe place to land and airdodge only if you expect an attack at that moment. I've seen aggressive ikes who try to hyphen smash (running usmash) you as you go to land. If you fastfall you should probably be able to land and shield in time and then punish, but if you have trouble with that you can always just counter or simply double jump + fastfall to safety.
Ikes usually try to control the ground and attack during landing lag(/wifi lag) if you're not careful. You just need to keep a clear head and land safely when he hits you up. Punish with dancing blade, get him offstage and gimp him. He shouldn't really be gimping you. Just airdodge his offstage attack, and don't let him get above you to spike. If he's spiking you its because hes predicting your jump when he gets you offstage.
The only other thing to remember is eruption, which is a devastating move if you don't expect it and he's smart about it.
I agree with everyone else that it's an easy matchup, but I also think Ike is underestimated in general.
