NSOperation inside NSOperationQueue not being executed
- by Martin Garcia
I really need help here. I'm desperate at this point.
I have NSOperation that when added to the NSOperationQueue is not being triggered.
I added some logging to see the NSOperation status and this is the result:
Queue operations count = 1
Queue isSuspended = 0
Operation isCancelled? = 0
Operation isConcurrent? = 0
Operation isFinished? = 0
Operation isExecuted? = 0
Operation isReady? = 1
Operation dependencies? = 0
The code is very simple. Nothing special.
LoadingConflictEvents_iPad *loadingEvents = [[LoadingConflictEvents_iPad alloc] initWithNibName:@"LoadingConflictEvents_iPad" bundle:[NSBundle mainBundle]];
loadingEvents.modalPresentationStyle = UIModalPresentationFormSheet;
loadingEvents.conflictOpDelegate = self;
[self presentModalViewController:loadingEvents animated:NO];
[loadingEvents release];
ConflictEventOperation *operation = [[ConflictEventOperation alloc] initWithParameters:wiLr.formNumber pWI_ID:wiLr.wi_id];
[queue addOperation:operation];
NSLog(@"Queue operations count = %d",[queue operationCount]);
NSLog(@"Queue isSuspended = %d",[queue isSuspended]);
NSLog(@"Operation isCancelled? = %d",[operation isCancelled]);
NSLog(@"Operation isConcurrent? = %d",[operation isConcurrent]);
NSLog(@"Operation isFinished? = %d",[operation isFinished]);
NSLog(@"Operation isExecuted? = %d",[operation isExecuting]);
NSLog(@"Operation isReady? = %d",[operation isReady]);
NSLog(@"Operation dependencies? = %d",[[operation dependencies] count]);
[operation release];
Now my operation do many things on the main method, but the problem is never being called. The main is never executed.
The most weird thing (believe me, I'm not crazy .. yet). If I put a break point in any NSLog line or in the creation of the operation the main method will be called and everything will work perfectly.
This have been working fine for a long time. I have been making some changes recently and apparently something screw things up. One of those changes was to upgrade the device to iOS 5.1 SDK (iPad).
To add something, I have the iPhone (iOS 5.1) version of this application that use the same NSOperation object. The difference is in the UI only, and everything works fine.
Any help will be really appreciated.
Regards,
