1:主程序底部TabBar的功能实现
效果图：
主要代码如下：
- (UITabBarController*)setRootVC:(BOOL)bShowCart
{
//创建一个子控制器 用于显示当前的tab
TabHomeVC *homeVC = [[TabHomeVC alloc] init];
//每个tab都是一个nav的内容，这样每个都是自个的nav，进行跳转
UINavigationController *homeNav = [[UINavigationController alloc] initWithRootViewController:homeVC];
UIImage *unselectedImage = [UIImage imageNamed:@"tab-home"];
UIImage *selectedImage = [UIImage imageNamed:@"tab-home-s"]; homeVC.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"首页"
image:[unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
selectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
homeVC.tabBarItem.tag = ; TabProductVC *proVC = [[TabProductVC alloc] init];
UINavigationController *proNav = [[UINavigationController alloc] initWithRootViewController:proVC];
unselectedImage = [UIImage imageNamed:@"tab-pro"];
selectedImage = [UIImage imageNamed:@"tab-pro-s"]; proNav.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"所有商品"
image:[unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
selectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
proNav.tabBarItem.tag = ; TabNewestVC * newVc = [[TabNewestVC alloc] init];
UINavigationController * newNav = [[UINavigationController alloc] initWithRootViewController:newVc];
unselectedImage = [UIImage imageNamed:@"tab-new"];
selectedImage = [UIImage imageNamed:@"tab-new-s"]; newNav.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"最新揭晓"
image:[unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
selectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
newNav.tabBarItem.tag = ; TabShopCartVC * cartVc = [[TabShopCartVC alloc] init];
UINavigationController * cartNav = [[UINavigationController alloc] initWithRootViewController:cartVc];
unselectedImage = [UIImage imageNamed:@"tab-cart"];
selectedImage = [UIImage imageNamed:@"tab-cart-s"]; cartNav.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"购物车"
image:[unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
selectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
cartNav.tabBarItem.tag = ; TabMineVC * mineVc = [[TabMineVC alloc] init];
UINavigationController * mineNav = [[UINavigationController alloc] initWithRootViewController:mineVc];
unselectedImage = [UIImage imageNamed:@"tab-mine"];
selectedImage = [UIImage imageNamed:@"tab-mine-s"]; mineNav.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"我的云购"
image:[unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
selectedImage:[selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
mineNav.tabBarItem.tag = ; //把上面的控制器增加到uitabbarcontroller的数组里
UITabBarController *tabBarController = [[UITabBarController alloc] init];
if(bShowCart)
tabBarController.viewControllers = @[homeNav,proNav,newNav,cartNav,mineNav];
else
tabBarController.viewControllers = @[homeNav,proNav,newNav,mineNav];
tabBarController.delegate = self; //设置一些样式内容
// customise TabBar UI Effect
[UITabBar appearance].tintColor = BG_COLOR; [[UITabBarItem appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:TABBAR_TEXT_NOR_COLOR} forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName:TABBAR_TEXT_HLT_COLOR} forState:UIControlStateSelected]; // customise NavigationBar UI Effect
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageWithRenderColor:NAVBAR_COLOR renderSize:CGSizeMake(., .)] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTitleTextAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:.],NSForegroundColorAttributeName:[UIColor blackColor]}]; UITabBar *tabBar = tabBarController.tabBar;
tabBar.backgroundColor = BG_COLOR; return tabBarController;
} - (void)setCartNum
{
//获得UITabBarController
UITabBarController* tabVC = (UITabBarController*)self.window.rootViewController;
//获得其中第四个 也就是购物车那个tabbar
UINavigationController* navVC = [tabVC.viewControllers objectAtIndex:];
__weak typeof (navVC) wNav = navVC;
//给它增加一个数字标识
[CartModel quertCart:nil value:nil block:^(NSArray* result){
if(result.count > )
wNav.tabBarItem.badgeValue = [NSString stringWithFormat:@"%d",(int)result.count];
else
wNav.tabBarItem.badgeValue = nil;
}];
} - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self setWindow:[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]];
//加载初始化的那个tab
UIViewController *rootViewController = [self setRootVC:YES];
[[self window] setRootViewController:rootViewController];
//显示是否有数字标识
[self setCartNum];
// set backgroundColor
[[self window] setBackgroundColor:[UIColor whiteColor]];
// set makeKeyAndVisible
[[self window] makeKeyAndVisible]; return YES;
}
注意：这边为每个tabBarController的子控件都增加一个nav，这样就可以在每个选项卡里都实现nav的跳转，把这个tabBarController作为整个的rootViewController;其中在其它控制器调用AppDelegate的方法setCarNum，可以[(AppDelegate*)[[UIApplication sharedApplication] delegate] setCartNum];
2：登录页面两输入框效果的实现
效果图：
主要代码：
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"登录";
self.view.backgroundColor = [UIColor hexFloatColor:@"f8f8f8"];
__weak typeof (self) wSelf = self;
[self actionCustomLeftBtnWithNrlImage:@"btnback" htlImage:@"btnback" title:@"" action:^{
[wSelf btnBackAction];
}];
UIImageView* line1 = [[UIImageView alloc] initWithFrame:CGRectMake(, , mainWidth - , 0.5)];
line1.backgroundColor = [UIColor hexFloatColor:@"dedede"];
[self.view addSubview:line1];
UIImageView* line3 = [[UIImageView alloc] initWithFrame:CGRectMake(, , mainWidth - , 0.5)];
line3.backgroundColor = [UIColor hexFloatColor:@"dedede"];
[self.view addSubview:line3];
UIImageView* line4 = [[UIImageView alloc] initWithFrame:CGRectMake(, , 0.5, )];
line4.backgroundColor = [UIColor hexFloatColor:@"dedede"];
[self.view addSubview:line4];
UIImageView* line5 = [[UIImageView alloc] initWithFrame:CGRectMake(mainWidth - , , 0.5, )];
line5.backgroundColor = [UIColor hexFloatColor:@"dedede"];
[self.view addSubview:line5];
UIView* vUser = [[UIView alloc] initWithFrame:CGRectMake(16.5, 20.5, mainWidth - , )];
vUser.backgroundColor = [UIColor whiteColor];
[self.view addSubview:vUser];
UIImageView* line2 = [[UIImageView alloc] initWithFrame:CGRectMake(, , mainWidth - , 0.5)];
line2.backgroundColor = [UIColor hexFloatColor:@"dedede"];
[self.view addSubview:line2];
UIImageView* imgUser = [[UIImageView alloc] initWithFrame:CGRectMake(, , , )];
imgUser.image = [UIImage imageNamed:@"login_name"];
[vUser addSubview:imgUser];
txtUser = [[UITextField alloc] initWithFrame:CGRectMake(, , vUser.frame.size.width - , )];
txtUser.placeholder = @"请输入您的手机号/邮箱号";
txtUser.clearButtonMode = UITextFieldViewModeWhileEditing;
txtUser.font = [UIFont systemFontOfSize:];
txtUser.text = [[NSUserDefaults standardUserDefaults] objectForKey:kLoginUsername];
[vUser addSubview:txtUser];
UIImageView* imgPwd = [[UIImageView alloc] initWithFrame:CGRectMake(, , , )];
imgPwd.image = [UIImage imageNamed:@"login_password"];
[vUser addSubview:imgPwd];
txtPwd = [[UITextField alloc] initWithFrame:CGRectMake(, , vUser.frame.size.width - , )];
txtPwd.placeholder = @"请输入您的密码";
txtPwd.clearButtonMode = UITextFieldViewModeWhileEditing;
txtPwd.font = [UIFont systemFontOfSize:];
txtPwd.secureTextEntry = YES;
[vUser addSubview:txtPwd];
UIButton* btnLogin = [[UIButton alloc] initWithFrame:CGRectMake(, , mainWidth - , )];
btnLogin.layer.cornerRadius = ;
btnLogin.backgroundColor = mainColor;
[btnLogin setTitle:@"登录" forState:UIControlStateNormal];
[btnLogin addTarget:self action:@selector(btnLoginAction) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btnLogin];
UIButton* btnReg = [[UIButton alloc] initWithFrame:CGRectMake(mainWidth - , , , )];
[btnReg setTitle:@"新用户注册" forState:UIControlStateNormal];
btnReg.titleLabel.font = [UIFont systemFontOfSize:];
[btnReg setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];
[btnReg addTarget:self action:@selector(btnRegAction) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btnReg];
}
注意：它是通过几条背景线跟图片和输入框进行一个组合
