Arc and performSelector

I have this code:
for( id aThing in someArray )
{
if ( [ aThing respondsToSelector: @selector(setTitle:) ] )
{
[ self replaceIn: aThing
readSelector: @selector(title)
writeSelector: @selector(setTitle:)
withTable: tableName
];
}
}
- (void)replaceIn: thing readSelector: (SEL)selectorIn writeSelector: (SEL)selectorOut withTable: (NSString *)tableName;
{
NSString *key = [ thing performSelector: selectorIn ];
...
NSString *rep = ...
[ thing performSelector: selectorOut withObject: rep ];
}
Now, using Arc I am told that "PerformSelector may cause a leak because its selector is unknown".
What I am supposed to do about this? I really want to have code without warnings.
Kind regards,
Gerriet.
