自定义tabBar能够解决自定义图片无法显示(只显示一块颜色)这个弊端,自定义tabBar要继承UITabBarController

原图片:

(1), (2),(3), (4),(5)

下面是自定义了一个TabBar ,每个按钮可以显示图片(自定义避免了图片无法显示只显示一块颜色)

效果图:

代码实现:

- (void)loadViewController

{

CoverCollectionViewController*coverVC = [[CoverCollectionViewControlleralloc]init];

coverVC.title=@"每日封面";

CustomizedNavigationController*coverNaVC = [[CustomizedNavigationControlleralloc]initWithRootViewController:coverVC];

coverNaVC.navigationItem.title=@"iDailyWATCh";

NewsTableViewController*newsVC = [[NewsTableViewControlleralloc]init];

newsVC.title=@"腕表杂志";

CustomizedNavigationController*newsNaVC = [[CustomizedNavigationControlleralloc]initWithRootViewController:newsVC];

BrandsTableViewController*brandsVC = [[BrandsTableViewControlleralloc]init];

brandsVC.title=@"品牌维基";

CustomizedNavigationController*brandsNaVC = [[CustomizedNavigationControlleralloc]initWithRootViewController:brandsVC];

VideosCollectionViewController*videosVC = [[VideosCollectionViewControlleralloc]init];

videosVC.title=@"视频";

CustomizedNavigationController*videosNaVC = [[CustomizedNavigationControlleralloc]initWithRootViewController:videosVC];

MoreViewController*moreVC = [[MoreViewControlleralloc]init];

moreVC.title=@"更多";

CustomizedNavigationController*moreNaVC = [[CustomizedNavigationControlleralloc]initWithRootViewController:moreVC];

self.viewControllers=@[coverNaVC, newsNaVC, brandsNaVC, videosNaVC, moreNaVC];

//使用的宏释放内存:(#define RELEASE_SAFE(_Pointer) do{[_Pointer release],_Pointer = nil;}while(0)

)

RELEASE_SAFE(coverNaVC);

RELEASE_SAFE(coverVC);

RELEASE_SAFE(brandsNaVC);

RELEASE_SAFE(brandsVC);

RELEASE_SAFE(videosNaVC);

RELEASE_SAFE(videosVC);

RELEASE_SAFE(moreNaVC);

RELEASE_SAFE(moreVC);

}

- (void)loadCustomizedTabBarView

{

//初始化自定义TabBar背景

UIImageView*tabBarBG = [[UIImageViewalloc]initWithFrame:CGRectMake(0,519,320,49)];

tabBarBG.userInteractionEnabled=YES;

tabBarBG.p_w_picpath= [UIImagep_w_picpathNamed:@"background"];

[self.viewaddSubview:tabBarBG];

[tabBarBGrelease];

//初始化自定义TabBarItem -> Button

for(intindex =0; index <5; index++) {

UIButton*button = [UIButtonbuttonWithType:UIButtonTypeSystem];

button.backgroundColor= [UIColorwhiteColor];

button.tag= index;

NSString*p_w_picpathName = [NSStringstringWithFormat:@"%d", index +100];

[buttonsetBackgroundImage:[UIImagep_w_picpathNamed:p_w_picpathName]forState:UIControlStateNormal];

button.frame=CGRectMake(3+64* index,5,290/5,39);

[tabBarBGaddSubview:button];

[buttonaddTarget:selfaction:@selector(changeViewController:)forControlEvents:UIControlEventTouchUpInside];

}

}

//实现对应按钮和页面的跳转

- (void)changeViewController:(UIButton*)button

{

self.selectedIndex= button.tag;

}
