IOS实现自定义透明背景的tabbar

话不多说，直接看示例代码

```//UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake（0, 0, kScreenW, tabBarHeight + 5）];//[imageView setImage:[self createImageWithColor:[UIColor clearColor]]];//[imageView setContentMode:UIViewContentModeScaleToFill];//[self.tabBar insertSubview:imageView atIndex:0];//覆盖原生Tabbar的上横线//[[UITabBar appearance] setShadowImage:[self createImageWithColor:[UIColor clearColor]]];//背景图片为透明色//[[UITabBar appearance] setBackgroundImage:[self createImageWithColor:[UIColor clearColor]]];self.tabBar.backgroundColor = [UIColor clearColor];//设置为半透明self.tabBarController.tabBar.translucent = YES;``````-（UIImage*） createImageWithColor:（UIColor*） color{CGRect rect=CGRectMake（0.0f, 0.0f, 1.0f, 1.0f）;UIGraphicsBeginImageContext（rect.size）;CGContextRef context = UIGraphicsGetCurrentContext（）;CGContextSetFillColorWithColor（context, [color CGColor]）;CGContextFillRect（context, rect）;UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext（）;UIGraphicsEndImageContext（）;return theImage;}```
