霓虹灯

基于OC实现的霓虹灯效果，看着有点刺眼。。。不过很好玩。
效果图：
这里写图片描述
你需要做的东西，就是用Xcode新建一个iOS工程，然后将下面代码敲上就可以实现。
代码如下：

UIView *yellow = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 375, 600)];    yellow.backgroundColor = [UIColor yellowColor];    yellow.center = CGPointMake((self.window.frame.size.width) / 2, (self.window.frame.size.height) / 2);    yellow.tag = 1;    [self.window addSubview:yellow];    [yellow release];    UIView *red = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 500)];    red.backgroundColor = [UIColor redColor];    red.center = CGPointMake((self.window.frame.size.width) / 2, (self.window.frame.size.height) / 2);    red.tag = 2;    [self.window addSubview:red];    [red release];    UIView *blue = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 225, 400)];    blue.backgroundColor = [UIColor blueColor];    blue.center = CGPointMake((self.window.frame.size.width) / 2, (self.window.frame.size.height) / 2);    blue.tag = 3;    [self.window addSubview:blue];    [blue release];    UIView *green = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 300)];    green.backgroundColor = [UIColor greenColor];    green.center = CGPointMake((self.window.frame.size.width) / 2, (self.window.frame.size.height) / 2);    green.tag = 4;    [self.window addSubview:green];    [green release];    UIView *gray = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 75, 200)];    gray.backgroundColor = [UIColor grayColor];    gray.center = CGPointMake((self.window.frame.size.width) / 2, (self.window.frame.size.height) / 2);    gray.tag = 5;    [self.window addSubview:gray];    [gray release];    self.timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(change) userInfo:nil repeats:YES];

下面是一个方法：

- (void)change{    UIView *yellow = [self.window viewWithTag:1];    UIView *red = [self.window viewWithTag:2];    UIView *blue = [self.window viewWithTag:3];    UIView *green = [self.window viewWithTag:4];    UIView *gray = [self.window viewWithTag:5];    UIView *temp = [[UIView alloc] init];    temp.backgroundColor = yellow.backgroundColor;    yellow.backgroundColor = red.backgroundColor;    red.backgroundColor = blue.backgroundColor;    blue.backgroundColor = green.backgroundColor;    green.backgroundColor = gray.backgroundColor;    gray.backgroundColor = temp.backgroundColor;}

应该就是这些了，基本的小东西，挺好玩的。
