billibala / XCTestAsync.mm
Created October 10, 2013 10:51
Call "waitForCompletion" after invoking an async method. Upon receiving notification, set "executionDate" to YES and call [runloopExpirationTimer fire]. This will "dry up" the fake run loop.
- (void)waitForCompletion {
runloopExpirationTimer = [NSTimer scheduledTimerWithTimeInterval:600.0 target:self selector:@selector(dumbTimerMethod:) userInfo:nil repeats:NO];
while ( !executionDone ) {
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
}
}
- (void)dumbTimerMethod:(NSTimer *)theTimer {
runloopExpirationTimer = nil;
}
