问题 I'm using ReactiveCocoa to update a UILabel whilst a UIProgressView counts down: NSInteger percentRemaining = ...; self.progressView.progress = percentRemaining / 100.0; __block NSInteger count = [self.count]; [[[RACSignal interval:0.05 onScheduler:[RACScheduler mainThreadScheduler]] take: percentRemaining] subscribeNext:^(id x) { count++; self.countLabel.text = [NSString stringWithFormat:@"%d", count]; self.progressView.progress = self.progressView.progress - 0.01; } completed:^{ // Move
