Question
Recently I use NSTimer to repeat taking photos, it'll show on the screen.
This is the problem:
I need to execute my app. & taking photos at the same time. So, does there any way to take photos at background?
I'll appreciate for any opinions~
Solution
Look into NSThread
's detachNewThreadSelector:toTarget:withObject:
method.
For example:
[NSThread detachNewThreadSelector:@selector(takePictures) toTarget:self withObject:nil];
Somewhere else in your class, you'd have:
- (void) takePictures {
// insert code to take pictures...
}
