Question

AppDelegate has a parameter called user,

and user has two parameters called userId & departmentId.

I just want to access my WebService use the ASIHttpRequest API,

but before I send the request,

there is error EXC_BAD_ACCESS with in this code:

    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
    NSString *userId = appDelegate.user.userId;
    NSString *departmentId = appDelegate.user.departmentId;
    NSLog(@"xxxxx:%@",userId);//this can log 29
    NSLog(@"xxxxx:%@",departmentId);//this can log 17
    NSString *URL = [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetAnnouncement?userId=%@&departmentId=%@&pageIndex=%@&pageSize=%@",userId,departmentId,1,10]; ***//ERROR***

The userId’s value is 29 and the departmentId’s value is 17,

then I change code to:

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetAnnouncement?userId=%@&departmentId=%@&pageIndex=%@&pageSize=%@",userId,departmentId,1,10]];//also the same error

There is also the same error…

and I dont know why, so pls help me with this, thank you.

The last two argument to stringWithFormat: are not objects therefore you should not use the format specifier %@ instead use %d

 [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetAnnouncement?userId=%@&departmentId=%@&pageIndex=%d&pageSize=%d",userId,departmentId,1,10]
