Question

I got an table which is filled with VM’s and i have 2 variable of the datatype NSIndexPath called:
selectedindexpath(the row the user clicks on) and
selectedindexpathFortheVMtoTurnOn(so it knows which row to reload when the VM went on);
which is both made in the .h as @paramters(retain) ..

i got a function that turns on the VM’s and a function that CHECKS every 1 sec with a NSTimer if the guest is finally on then it reloads the row of selectedindexpathFortheVMtoTurnOn
im doing the same for OFF/REBOOT but i have got a problem with this.. im not able to request an action for more then 1 VM.. because it is overwriting the selectedindexpathFortheVMtoTurnOn value with the last row which i sent an action to and by doing so the table responds wierd and the app crashes..
so thats why i want to give the indexpath.row value as parameters with the NSTimer to the function that checks every 1 sec i have tried a few things but none have worked.. below the code of how i am giving the parameters

timertocallguest=[NSTimer scheduledTimerWithTimeInterval:1
                            target:self
                          selector:@selector(gettheguestyouaskedforTOTURNON:)
                        userInfo:selectedindexpathFortheVMtoTurnOn
                                             repeats:YES];

and the function:

-(void)gettheguestyouaskedforTOTURNON:(NSIndexPath *)therow

and when i try to do a NSLog("%d",therow.row); it crashes…

and with NSLog("%d",therow); i get a whole diffrent value of the selectedindexpathFortheVMtoTurnOn that it used to had..

what am i doing wrong.?

sorry if its a wall of text. but i realy need to fix this problem as this is getting released as BETA nextweek in the appstore for the company where my traineeperiode is.

ty in advance.

EDIT:

i will try to show it with pictures this time.
At first im at the view with VM’s

an activity indicator appears and it stops when the action is done.(which has to do with the NStimer that checks every 1 sec)

but when i try to do an action at 2 or more VM’s the activity indicator on the last row i selected spins *x faster(depends on how manny actions i send.. 2 actions means it spins 2 times faster..(so weird)

.. i hope this is enough for you to understand what i mean now =)

Answer 1

The method triggered by an NSTimer object always has the timer as the argument. You can get the row like this.

-(void)gettheguestyouaskedforTOTURNON:(NSTimer *)timer {
    NSIndexPath *indexPath = (NSIndexPath*)[timer userInfo];

    NSLog(@"%d", indexPath.row);
}
