Unable to provide a valid code, because it is unable to accurately locate what problem. I checked GCD dispatch_after scene, but it can't completely fix this problem.

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    view = [self myfunction];
});
