iOS-CYLTabBarController【好用的TabbarController】

用TabbarController進行模塊分類和管理，這里推薦一個CYLTabBarController，只需兩個數組就可以使用和管理；

 

1.導入CYLTabBarController

使用cocoapods導入即可 pod 'CYLTabBarController', '~> 1.14.1'，終端 pod install 即可

 

2.配置

新建一個基於 NSObject 類 MainTabBarControllerConfig，用於配置CYLTabBarController及管理；頭文件引入

#import <CYLTabBarController.h>

.h

@interface MainTabBarControllerConfig : NSObject
///CYLTabBarController @property (nonatomic,strong) CYLTabBarController *mainTabBarController; @end

.m

@implementation MainTabBarControllerConfig - (CYLTabBarController *)mainTabBarController{ if (!_mainTabBarController) { UIEdgeInsets imageInsets = UIEdgeInsetsZero; UIOffset titlePositionAdjustment = UIOffsetZero; _mainTabBarController = [CYLTabBarController tabBarControllerWithViewControllers:[self arrayViewControllerItem] tabBarItemsAttributes:[self arrayAttributesItem] imageInsets:imageInsets titlePositionAdjustment:titlePositionAdjustment]; [self customizeTabBarAppearance:_mainTabBarController]; } return _mainTabBarController; } - (NSArray *)arrayViewControllerItem{ BookcaseNavViewController *bookcaseNavi = [wkj_getSboardBookcase instantiateViewControllerWithIdentifier:@"BookcaseNavViewController"]; AskKaoLaNavViewController *askKlNavi = [wkj_getSboardAskKaoLa instantiateViewControllerWithIdentifier:@"AskKaoLaNavViewController"]; DiscoverNavViewController *discoverNavi = [wkj_getSboardDiscover instantiateViewControllerWithIdentifier:@"DiscoverNavViewController"]; UserNavViewController *userNavi = [wkj_getSboardUser instantiateViewControllerWithIdentifier:@"UserNavViewController"]; ///返回需要加載的模塊
    return @[bookcaseNavi,discoverNavi,askKlNavi,userNavi]; } - (NSArray *)arrayAttributesItem{ NSDictionary *bookcaseItemsAttributes =@{CYLTabBarItemTitle : @"nav1", CYLTabBarItemImage : @"bar_tk_01", /* NSString and UIImage are supported*/ CYLTabBarItemSelectedImage : @"bar_tk_02",}; NSDictionary *discoverItemsAttributes = @{CYLTabBarItemTitle : @"nav2", CYLTabBarItemImage : @"bar_kc_01", CYLTabBarItemSelectedImage : @"bar_kc_02",}; NSDictionary *askklItemsAttributes = @{CYLTabBarItemTitle : @"nav3", CYLTabBarItemImage : @"bar_dzs_01", CYLTabBarItemSelectedImage : @"bar_dzs_02",}; NSDictionary *userItemsAttributes = @{CYLTabBarItemTitle : @"nav4", CYLTabBarItemImage : @"bar_wd_01", CYLTabBarItemSelectedImage : @"bar_wd_02"}; NSArray *tabBarItemsAttributes = @[bookcaseItemsAttributes, discoverItemsAttributes, askklItemsAttributes, userItemsAttributes]; return tabBarItemsAttributes; } /** * 更多TabBar自定義設置：比如：tabBarItem 的選中和不選中文字和背景圖片屬性、tabbar 背景圖片屬性等等 */
- (void)customizeTabBarAppearance:(CYLTabBarController *)tabBarController { // Customize UITabBar height // 自定義 TabBar 高度 // tabBarController.tabBarHeight = CYLTabBarControllerHeight; // set the text color for unselected state // 普通狀態下的文字屬性
    NSMutableDictionary *normalAttrs = [NSMutableDictionary dictionary]; normalAttrs[NSForegroundColorAttributeName] = [UIColor grayColor]; // set the text color for selected state // 選中狀態下的文字屬性
    NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary]; selectedAttrs[NSForegroundColorAttributeName] = Wonderful_BlueColor6; // set the text Attributes // 設置文字屬性
    UITabBarItem *tabBar = [UITabBarItem appearance]; [tabBar setTitleTextAttributes:normalAttrs forState:UIControlStateNormal]; [tabBar setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected]; // Set the dark color to selected tab (the dimmed background) // TabBarItem選中后的背景顏色 // [self customizeTabBarSelectionIndicatorImage]; // update TabBar when TabBarItem width did update // If your app need support UIDeviceOrientationLandscapeLeft or UIDeviceOrientationLandscapeRight， // remove the comment '//' // 如果你的App需要支持橫豎屏，請使用該方法移除注釋 '//' // [self updateTabBarCustomizationWhenTabBarItemWidthDidUpdate]; // set the bar shadow image // This shadow image attribute is ignored if the tab bar does not also have a custom background image.So at least set somthing.
 [[UITabBar appearance] setBackgroundImage:[[UIImage alloc] init]]; [[UITabBar appearance] setBackgroundColor:[UIColor whiteColor]]; [[UITabBar appearance] setShadowImage:[UIImage imageNamed:@"tapbar_top_line"]]; // set the bar background image // 設置背景圖片 // UITabBar *tabBarAppearance = [UITabBar appearance]; // [tabBarAppearance setBackgroundImage:[UIImage imageNamed:@"tab_bar"]]; // remove the bar system shadow image // 去除 TabBar 自帶的頂部陰影 // [[UITabBar appearance] setShadowImage:[[UIImage alloc] init]];
}

 

3.使用

在AppDelegate.m  didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. // /加載中間自定義按鈕 // [TabbarPlusButton registerPlusButton];
    MainTabBarControllerConfig *tabbarConfig = [[MainTabBarControllerConfig alloc]init]; CYLTabBarController *mainTabbarController = tabbarConfig.mainTabBarController; [self.window setRootViewController:mainTabbarController]; return YES; }

 

 

 

4.自定義按鈕

加入中間按鈕之前，確保上面的功能已經實現；新建一個基於 CYLPlusButton 的類 TabbarPlusButton，實現代理 CYLPlusButtonSubclassing

 .h

@interface TabbarPlusButton : CYLPlusButton<CYLPlusButtonSubclassing>

@end

.m

@implementation TabbarPlusButton - (instancetype)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { self.titleLabel.textAlignment = NSTextAlignmentCenter; self.adjustsImageWhenHighlighted = NO; } return self; } //上下結構的 button
- (void)layoutSubviews { [super layoutSubviews]; // 控件大小,間距大小 // 注意：一定要根據項目中的圖片去調整下面的0.7和0.9，Demo之所以這么設置，因為demo中的 plusButton 的 icon 不是正方形。
    CGFloat const imageViewEdgeWidth   = self.bounds.size.width * 0.7; CGFloat const imageViewEdgeHeight  = imageViewEdgeWidth * 0.9; CGFloat const centerOfView    = self.bounds.size.width * 0.5; CGFloat const labelLineHeight = self.titleLabel.font.lineHeight; CGFloat const verticalMargin  = (self.bounds.size.height - labelLineHeight - imageViewEdgeHeight) * 0.5; // imageView 和 titleLabel 中心的 Y 值
    CGFloat const centerOfImageView  = verticalMargin + imageViewEdgeHeight * 0.5; CGFloat const centerOfTitleLabel = imageViewEdgeHeight  + verticalMargin * 2 + labelLineHeight * 0.5 + 5; //imageView position 位置
    self.imageView.bounds = CGRectMake(0, 0, imageViewEdgeWidth, imageViewEdgeHeight); self.imageView.center = CGPointMake(centerOfView, centerOfImageView); //title position 位置
    self.titleLabel.bounds = CGRectMake(0, 0, self.bounds.size.width, labelLineHeight); self.titleLabel.center = CGPointMake(centerOfView, centerOfTitleLabel); } #pragma mark -
#pragma mark - CYLPlusButtonSubclassing Methods

/* * Create a custom UIButton with title and add it to the center of our tab bar * */
+ (id)plusButton { TabbarPlusButton *button = [[TabbarPlusButton alloc] init];
 ///中間按鈕圖片 UIImage *buttonImage = [UIImage imageNamed:@"post_normal"]; [button setImage:buttonImage forState:UIControlStateNormal]; [button setTitle:@"發布" forState:UIControlStateNormal]; [button setTitleColor:[UIColor grayColor] forState:UIControlStateNormal]; [button setTitle:@"發布" forState:UIControlStateSelected]; [button setTitleColor:[UIColor blueColor] forState:UIControlStateSelected]; button.titleLabel.font = [UIFont systemFontOfSize:9.5]; [button sizeToFit]; // or set frame in this way `button.frame = CGRectMake(0.0, 0.0, 250, 100);` // button.frame = CGRectMake(0.0, 0.0, 250, 100); // button.backgroundColor = [UIColor redColor]; // if you use `+plusChildViewController` , do not addTarget to plusButton.
 [button addTarget:button action:@selector(clickPublish) forControlEvents:UIControlEventTouchUpInside]; return button; } /* * Create a custom UIButton without title and add it to the center of our tab bar * */
//+ (id)plusButton //{ //
// UIImage *buttonImage = [UIImage imageNamed:@"hood.png"]; // UIImage *highlightImage = [UIImage imageNamed:@"hood-selected.png"]; //
// CYLPlusButtonSubclass* button = [CYLPlusButtonSubclass buttonWithType:UIButtonTypeCustom]; //
// button.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleTopMargin; // button.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height); // [button setBackgroundImage:buttonImage forState:UIControlStateNormal]; // [button setBackgroundImage:highlightImage forState:UIControlStateHighlighted]; // [button addTarget:button action:@selector(clickPublish) forControlEvents:UIControlEventTouchUpInside]; //
// return button; //}

#pragma mark -
#pragma mark - Event Response

- (void)clickPublish { CYLTabBarController *tabBarController = [self cyl_tabBarController]; UIViewController *viewController = tabBarController.selectedViewController; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:nil cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照", @"從相冊選取", @"淘寶一鍵轉賣", nil]; [actionSheet showInView:viewController.view]; } #pragma mark - UIActionSheetDelegate

- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex { NSLog(@"buttonIndex = %@", @(buttonIndex)); } #pragma mark - CYLPlusButtonSubclassing

//+ (UIViewController *)plusChildViewController { // UIViewController *plusChildViewController = [[UIViewController alloc] init]; // plusChildViewController.view.backgroundColor = [UIColor redColor]; // plusChildViewController.navigationItem.title = @"PlusChildViewController"; // UIViewController *plusChildNavigationController = [[UINavigationController alloc] // initWithRootViewController:plusChildViewController]; // return plusChildNavigationController; //} //
//+ (NSUInteger)indexOfPlusButtonInTabBar { // return 4; //} //
//+ (BOOL)shouldSelectPlusChildViewController { // BOOL isSelected = CYLExternPlusButton.selected; // if (isSelected) { // NSLog(@"🔴類名與方法名：%@（在第%@行），描述：%@", @(__PRETTY_FUNCTION__), @(__LINE__), @"PlusButton is selected"); // } else { // NSLog(@"🔴類名與方法名：%@（在第%@行），描述：%@", @(__PRETTY_FUNCTION__), @(__LINE__), @"PlusButton is not selected"); // } // return YES; //}

+ (CGFloat)multiplierOfTabBarHeight:(CGFloat)tabBarHeight { return  0.3; } + (CGFloat)constantOfPlusButtonCenterYOffsetForTabBarHeight:(CGFloat)tabBarHeight { return  -10; } @end

 

最后在AppDelegate.m  didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中加上 [TabbarPlusButton registerPlusButton] 即可;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
//    /加載中間自定義按鈕
 [TabbarPlusButton registerPlusButton];
    MainTabBarControllerConfig *tabbarConfig = [[MainTabBarControllerConfig alloc]init];
    CYLTabBarController *mainTabbarController = tabbarConfig.mainTabBarController;
    [self.window setRootViewController:mainTabbarController];
    return YES;
}
