iPhone dev Stupidity 71: Loading ... 17% - How to Make progress b

1. iPhone threading and screen refreshs

    Use kind of server and inter PROCESS communicating. Quite complex.

2. Timely UI updates

    Use notification center as a mid man - but NOT working.

    Because a notification is despatched synchronously - UI still get no chance to update.

My solution (based on 2):

    Sending notification in a separate thread instead of notifying directly:

- (void) sendProgressNotification: (NSNumber *) percentDeltaValue{

[[NSNotificationCenter defaultCenter] postNotificationName:@"StepPercent" object: percentDeltaValue];

}

// post the progress info

- (void) stepPercentage: (int) percentDelta{

[NSThread detachNewThreadSelector: @selector(sendProgressNotification:) toTarget: self withObject: [NSNumber numberWithInt: percentDelta]];

}
