I have a code working fine in iOS7 & 8 that wait with a timeout to load some data stored in a file
dispatch_async(dispatch_get_main_queue(), ^{
...
}
then
[self.abCondition lock];
NSDate *timeoutDate = [NSDate dateWithTimeIntervalSinceNow:timeout];
NSDate *startDate = [NSDate date];
BOOL signaled=NO;
while (!self.isUpAndRunning && (signaled = [self.abCondition waitUntilDate:timeoutDate])) {
NSLog(@"waiting to sync");
}
With iOS9, the block in dispatch_async is not called.
After the timeout, then I can see that the block is called.
How can I change this code ?
