总结了大部分的界面 大概就如下三种情况：
打开左边抽屉，按钮后左边push到center控制器，这个控制器直接显示全部
(类似知乎日报)
思路：设置left的抽屉为center的nav并且关闭抽屉打开左边抽屉，按钮后左边push出一个新控制器，但是这个控制器直接显示全部
(类似qq)
思路：本质是用中间控制器的nav去push到对应的控制器 并且关闭中间控制器的push动画 然后再同时关闭抽屉 这样子会造成假象-
打开左边抽屉，按钮后左边push出一个新控制器，但是这个控制器仍然是显示左边抽屉里的
(我没见过由这么奇怪的需求)
思路：直接设置push

上代码
- pod 'MMDrawerController'
- 在AppDelegate中
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.mainController = [[mainController alloc] init];
self.window.rootViewController = self.mainController;
[self.window makeKeyAndVisible];
return YES;
}
为了不对AppDelegate有过多的入侵 我们将继承自MMDrawerController的mainController作为根控制器
- 在mainController.h中
//这里将centerNavVc写成public的接口方式 方便日后被拿到
@property (nonatomic,strong)UINavigationController * centerNavVc;
4.在mainController.m中
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor yellowColor];
//初始化
LeftViewController *leftVC = [[LeftViewController alloc] init];
//将leftVC作为leftNvaVC的根控制器
UINavigationController *leftNvaVC = [[UINavigationController alloc] initWithRootViewController:leftVC];
//将mainController作为赋值给leftVC
leftVC.delegate = self;
CenterViewController *centerVC = [[CenterViewController alloc] init];
self.centerNavVc = [[UINavigationController alloc] initWithRootViewController:centerVC];
//设置左中抽屉内是什么东西
self.centerViewController = self.centerNavVc;
self.leftDrawerViewController = leftNvaVC;
//4、设置打开/关闭抽屉的手势
self.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll;
self.closeDrawerGestureModeMask =MMCloseDrawerGestureModeAll;
//5、设置左边抽屉显示的多少
self.maximumLeftDrawerWidth = 200.0;
}
其实我们是将left的Nav和center的Nav添加到左中抽屉内，并且要在左边抽屉做响应的话leftVC.delegate = self 一定要写
- LeftViewController.h中
@property (nonatomic,strong) mainController *delegate;
方便取到mainController内的centerNavVc
- LeftViewController.m中
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor redColor];
self.title = @"left";
//push到center
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 176, 50, 50)];
btn.backgroundColor = [UIColor yellowColor];
[btn addTarget:self action:@selector(Click1) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
//push到新的控制器 在center中
UIButton *btn1 = [[UIButton alloc] initWithFrame:CGRectMake(0, 176+50, 50, 50)];
btn1.backgroundColor = [UIColor brownColor];
[btn1 addTarget:self action:@selector(click2) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn1];
//left push
UIButton *btn2 = [[UIButton alloc] initWithFrame:CGRectMake(0, 176+50+50, 50, 50)];
btn2.backgroundColor = [UIColor blackColor];
[btn2 addTarget:self action:@selector(Click3) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn2];
}
初始化
/**
* 加载控制器的时候设置打开抽屉模式 (因为在后面会关闭)
*/
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//设置打开抽屉模式
[self.delegate setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
}
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
}
要打开抽屉的手势模式，不然不能在后面不能使用
/push到center
- (void)Click1{
NSLog(@"%s",__func__);
CenterViewController *vc = [[CenterViewController alloc] init];
UINavigationController *navcenter = [[UINavigationController alloc] initWithRootViewController:vc];
[self.delegate setCenterViewController:navcenter withCloseAnimation:YES completion:nil];
}
设置left的抽屉为center的nav并且关闭抽屉
//push到新的控制器 在center中
- (void)click2{
NSLog(@"%s",__func__);
threeViewController *showVC = [[threeViewController alloc] init];
//拿到我们的LitterLCenterViewController，让它去push
UINavigationController* nav = (UINavigationController*)self.delegate.centerViewController;
[nav pushViewController:showVC animated:NO];
//当我们push成功之后，关闭我们的抽屉
[self.delegate closeDrawerAnimated:YES completion:^(BOOL finished) {
//设置打开抽屉模式为MMOpenDrawerGestureModeNone，也就是没有任何效果。
[self.delegate setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];
}];
}
本质是用中间控制器的nav去push到对应的控制器 并且关闭中间控制器的push动画 然后再同时关闭抽屉 这样子会造成假象
//left push
- (void)Click3{
NSLog(@"%s",__func__);
threeViewController *vc = [[threeViewController alloc] init];
[self.navigationController pushViewController:vc animated:YES];
}
直接拿到nav进行push
- CenterViewController.h没有操作
- CenterViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor greenColor];
self.title = @"center";
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 176, 50, 50)];
btn.backgroundColor = [UIColor yellowColor];
[btn addTarget:self action:@selector(Click1) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
/**
* 加载控制器的时候设置打开抽屉模式 (因为在后面会关闭)
*/
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//设置打开抽屉模式
[self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
}
-(void)Click1{ //打开左边抽屉
//这里的话是通过遍历循环拿到之前在AppDelegate中声明的那个MMDrawerController属性，然后判断是否为打开状态，如果是就关闭，否就是打开(初略解释，里面还有一些条件)
[self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];
}
回到center的时候要打开抽屉的手势 不然不能够打开左边抽屉
打开左边抽屉的方法
- threeViewController.h 没有操作
- threeViewController.m
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//关闭抽屉模式 push到该控制器时要关闭抽屉模式 不然会以此为center控制器打开左边抽屉
[self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];
}
- end
