- (void)resultarrays :(NSMutableArray *)Agentids loanofficerid:(NSMutableArray *)Loanofficerid agentname:(NSMutableArray *)agentname agentemail:(NSMutableArray *)agentemail agentphone:(NSMutableArray *)Agentphone {
agentids = [[NSMutableArray alloc] initWithObjects:Agentids,nil];
loanofficerid = [[NSMutableArray alloc] initWithObjects:Loanofficerid,nil];
agentnames = [[NSMutableArray alloc] initWithObjects:agentname,nil];
agentemails = [[NSMutableArray alloc] initWithObjects:agentemail,nil];
agentphone = [[NSMutableArray alloc] initWithObjects:Agentphone,nil];
NSLog(#"123 %#",agentids);
NSLog(#"123 %#",loanofficerid);
NSLog(#"123 %#",agentnames);
NSLog(#"123 %#",agentphone);
}
in myclass.m i write this
myclassviewcontroller *LOVobj = [[myclassviewcontroller alloc]init];
[LOVobj resultarrays:resultData_agent loanofficerid:array1 agentname:array2 agentemail:array3 agentphone:array4];

Answer 1

First of all, change the code to this:
- (void)resultarrays :(NSArray *)Agentids loanofficerid:(NSArray *)Loanofficerid agentname:(NSArray *)agentname agentemail:(NSArray *)agentemail agentphone:(NSArray *)Agentphone {
agentids = [[NSMutableArray alloc] initWithArray: Agentids];
loanofficerid = [[NSMutableArray alloc] initWithArray: Loanofficerid];
agentnames = [[NSMutableArray alloc] initWithArray: agentname];
agentemails = [[NSMutableArray alloc] initWithArray: agentemail];
agentphone = [[NSMutableArray alloc] initWithArray: Agentphone];
NSLog(#"123 %#",agentids);
NSLog(#"123 %#",loanofficerid);
NSLog(#"123 %#",agentnames);
NSLog(#"123 %#",agentphone);
}
Don't pass mutable array if you don't want it to change.

First of all, you're creating arrays containing references to arrays, not arrays of the objects in the parameter arrays. And since you're storing the references of the parameter arrays, if the contents of the parameter arrays changes, so will all the references.
You probably instead want something like this for each array:
agentids = [NSMutableArray arrayWithArray: Agentids];
(and [agentids retain] since arrayWithArray returns an auto-released object).
