iOS UITabBar添加背景圖檔、去掉shadow線

//[[UITabBar appearance] setBackgroundImage:[[UIImage imageNamed:@“tabbarBack”] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];//此種方法改變背景,但是圖檔變短重複鋪

UIImageView *ima = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@“tabbarBack”]];

ima.frame = CGRectMake(0,0,self.view.frame.size.width, 49);

self.tabBar.opaque = YES;

[self.tabBar insertSubview:ima atIndex:0];

//去黑線

[[UITabBar appearance] setShadowImage:[[UIImage alloc] init]];

[UITabBar appearance].layer.borderWidth = 0.0f;

[UITabBar appearance].clipsToBounds = YES;
