IT工程師數位筆記本

首先聲明一下，此文檔是由本人看到別人寫的，然后感覺挺不錯的，為了以后查看方便，再次重新寫一下，請原作者原諒

1，以前基本上都是用系統的tabbar或者是自己完全自定義的，從來都沒有向這兩方面合起來想過

首先創建一個project

其次在AppDelegate.m里面這樣寫道，見

#import "AppDelegate.h"#import "TabbarVC.h"@interface AppDelegate ()@end@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {// Override point for customization after application launch.TabbarVC *tabbar = [[TabbarVC alloc]init];tabbar.delegate = self;self.window.backgroundColor = [UIColor whiteColor];self.window.rootViewController = tabbar;return YES;}//設置tabbar上的第三個按鈕不可選-(BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{return ![viewController isEqual:tabBarController.viewControllers[2]];}

二，TabbarVC.h 為自定義的tabbar

在tabbar的TabbarVC.m中這樣寫道

#import "TabbarVC.h"#import "ViewController.h"#import "ViewController1.h"#import "ViewController2.h"#import "ViewController3.h"#import "ViewController4.h"@interface TabbarVC ()@property (nonatomic, strong) UIView *baseView;@end@implementation TabbarVC- (void)viewDidLoad {[super viewDidLoad];UINavigationController *vC = [self className:@"ViewController" vcTitle:@"消息" tabTitle:@"消息" tabImage:@"release" tabSelectedImage:@"release"];UINavigationController *vC1 = [self className:@"ViewController1" vcTitle:@"通知" tabTitle:@"通知" tabImage:@"U-assn" tabSelectedImage:@"U-assn"];UINavigationController *vC2 = [self className:@"ViewController2" vcTitle:@"人物" tabTitle:@"人物" tabImage:@"U-city" tabSelectedImage:@"U-city"];UINavigationController *vC3 = [self className:@"ViewController3" vcTitle:@"列表" tabTitle:@"列表" tabImage:@"U-me" tabSelectedImage:@"U-me"];UINavigationController *vC4 = [self className:@"ViewController4" vcTitle:@"你好" tabTitle:@"你好" tabImage:@"UU" tabSelectedImage:@"UU"];self.viewControllers = @[vC,vC1,vC2,vC3,vC4];//自定義按鈕UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake((self.view.bounds.size.width - 40)/2, 5, 40, 40)];[btn setImage:[UIImage imageNamed:@"point"] forState:UIControlStateNormal];[btn addTarget:self action:@selector(tabBarDidClickPlusButton) forControlEvents:UIControlEventTouchUpInside];[self.tabBar addSubview:btn];}- (UINavigationController *)className:(NSString *)classNamevcTitle:(NSString *)vcTitletabTitle:(NSString *)tabTitletabImage:(NSString *)imagetabSelectedImage:(NSString *)selectedImage{UIViewController *vc = [[NSClassFromString(className) alloc] init];vc.title = vcTitle;vc.tabBarItem.title = tabTitle;vc.tabBarItem.image = [UIImage imageNamed:image];vc.tabBarItem.selectedImage = [UIImage imageNamed:selectedImage];UINavigationController *navgation = [[UINavigationController alloc] initWithRootViewController:vc];return navgation;}- (void)tabBarDidClickPlusButton{_baseView = [[UIView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height-250, self.view.frame.size.width, 200)];_baseView.backgroundColor = [UIColor orangeColor];[self.view addSubview:_baseView];UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(romoveBaseView)];[_baseView addGestureRecognizer:tapGesture];}- (void)romoveBaseView{[_baseView removeFromSuperview];}
