init instance variable multiple times

can this code cause any potential trouble?

@property (nonatomic, retain) NSDictionary *instanceDictionary;

for(int i = 0; i < 50; i++){
   self.instanceDictionary = [NSDictionary alloc] init];
}

or without self

for(int i = 0; i < 50; i++){
   instanceDictionary = [NSDictionary alloc] init];
}

I came across situations where a instance variable gets "overridden" like this and was wondering if it could cause any memory problems.

It won't cause any "memory problem". In your code, at each loop iteration, the instanceDictionary is replaced with a new one.
ARC will take care of releasing the previous one automatically.
This code is pretty useless though.
