iOS项目中三级控制器搭建(UITabBarController+UINavigationController+UIViewController)

释放双眼,带上耳机,听听看~!

在项目一开始搭建TabBarControler和NavigationController的时候,很多人习惯自定义TabBar。

其实系统的自带的设置TabBarControler、对应的子控制器、对应的Tabbar上的image和title更简单,但有些人出现了图片莫名变得很大或Tabbar上的title跟控制器的Title冲突的问题,下面的解决办法仅作参考,如有问题,请私信我。

#import "MainTabBarController.h"
#import "BaseNavigationController.h"
#import "HomeViewController.h"
#import "FindViewController.h"
#import "AccountViewController.h"
@interface MainTabBarController ()<UITabBarDelegate>
@end
@implementation MainTabBarController
- (void)viewDidLoad {
[super viewDidLoad];
[[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:10]} forState:UIControlStateNormal];
UIColor *titleHighlightedColor = [UIColor colorWithHexString:MainBlueColor];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
titleHighlightedColor, NSForegroundColorAttributeName,
nil] forState:UIControlStateSelected];
self.tabBar.barTintColor = [UIColor colorWithHexString:MainWhiteColor];
self.tabBar.translucent = NO;
[self navigationControllers];
}

tabBarItem中的图片变得特别大怎么解决?

在赋图片的时候使用UIImageRenderingModeAlwaysOriginal模式
findNaviVC.tabBarItem.selectedImage=[select2 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

- (void)navigationControllers{
HomeViewController *homeVC = [[HomeViewController alloc] init];
BaseNavigationController *homeNaviVC = [[BaseNavigationController alloc] initWithRootViewController:homeVC];
homeNaviVC.tabBarItem.title = @"首页";
homeNaviVC.tabBarItem.image = [UIImage imageNamed:@"1_1"];
UIImage *select = [UIImage imageNamed:@"1_2"];
homeNaviVC.tabBarItem.selectedImage = [select imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
FindViewController *findVC = [[FindViewController alloc] init];
BaseNavigationController *findNaviVC = [[BaseNavigationController alloc] initWithRootViewController: findVC];
findNaviVC.tabBarItem.title = @"发现";
findNaviVC.tabBarItem.image = [UIImage imageNamed:@"1_3"];
UIImage *select2 = [UIImage imageNamed:@"1_4"];
findNaviVC.tabBarItem.selectedImage = [select2 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
AccountViewController *accountVC = [[AccountViewController alloc] init];
BaseNavigationController *accountNaviVC = [[BaseNavigationController alloc] initWithRootViewController:accountVC];
accountNaviVC.tabBarItem.title = @"我的账户";
accountNaviVC.tabBarItem.image = [UIImage imageNamed:@"1_5"];
UIImage *select3 = [UIImage imageNamed:@"1_6"];
accountNaviVC.tabBarItem.selectedImage = [select3 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.viewControllers = @[homeNaviVC,findlNaviVC,accountNaviVC];
}

TabBar上的title和控制器导航栏的title不一致怎么解决?

在该tabbarItem对应的导航控制器的RootVC的viewDidLoad中
使用self.navigationItem.title = @”导航栏首页”;
不要直接self.title = @”导航栏首页”;(会冲突)
