ios - Multiple methods named "setLength" found -
i have code:

any ideas on should fix it?
assign results of [self.receiveddata objectforkey:[nsnumber numberwithint:connection.tag]] variable of proper type. call setlength: method on variable.
btw - use modern syntax:
self.receiveddata[@(connection.tag)]; the @(connection.tag) replaces use of [nsnumber numberwithint:connection.tag] , self.receiveddata[xxx] replaces use of objectforkey:.
