我们在iPhone或者iPad中，除了导航栏，标签栏之外，最常用的界面切换就是菜单栏了，今天就给大家分享点干货，很简单的代码。为了方便，我能把实现都放在VC里， 大家在写工程的时候可不要和我学，尽量减轻VC的负担，好了不费话了， 下面上代码块。
属性
@property (nonatomic, strong) UIButton *menuOne;
@property (nonatomic, strong) UIButton *menuTwo;
@property (nonatomic, strong) UIButton *menuThree;
初始化
-(void)config{
// menuOne的创建
self.menuOne = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];
[self.view addSubview:_menuOne];
[self.menuOne setShowsTouchWhenHighlighted:YES];//高亮
self.menuOne.backgroundColor = [UIColor cyanColor];
[self.menuOne setTitle:@"菜单1" forState:UIControlStateNormal];
[self.menuOne setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.menuOne setTag:100];
//MenuTwo的创建
self.menuTwo = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];
[self.menuTwo setShowsTouchWhenHighlighted:YES];//高亮
[self.menuTwo setBackgroundColor:[UIColor orangeColor]];
[self.menuTwo setTitle:@"菜单2" forState:UIControlStateNormal];
[self.menuTwo setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.menuTwo setTag:101];
// [self.menuTwo addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:_menuTwo];
//MenuThree的创建
self.menuThree = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];
[self.menuThree setShowsTouchWhenHighlighted:YES];//高亮
[self.menuThree setBackgroundColor:[UIColor redColor]];
[self.menuThree setTitle:@"菜单3" forState:UIControlStateNormal];
[self.menuThree setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.menuThree setTag:102];
// [self.menuThree addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:_menuThree];
//向左滑动的手势
UISwipeGestureRecognizer *sgrLeft = [[UISwipeGestureRecognizer alloc]init];
[sgrLeft setDirection:UISwipeGestureRecognizerDirectionLeft];//设置方向
[sgrLeft addTarget:self action:@selector(selectMenuItemLeft)];
[self.view addGestureRecognizer:sgrLeft];
// 向右滑动的手势
UISwipeGestureRecognizer *sgrRight = [[UISwipeGestureRecognizer alloc]init];
[sgrRight setDirection:UISwipeGestureRecognizerDirectionRight];//设置方向
[sgrRight addTarget:self action:@selector(selectMenuItemRight)];
[self.view addGestureRecognizer:sgrRight];
}
方法的实现
-(void)selectMenuItemLeft{
CATransition *animation = [CATransition animation];
animation.duration = 0.8;//动画时间
animation.type = @"cube";
animation.subtype = kCATransitionFromLeft;//设置方向
UIButton *lastView = (UIButton *)[self.view.subviews lastObject];//找到最上层的view
if (lastView.tag == 100) {
[self.view bringSubviewToFront:self.menuThree];
}else if (lastView.tag == 101){
[self.view bringSubviewToFront:self.menuOne];
}else if (lastView.tag == 102){
[self.view bringSubviewToFront:self.menuTwo];
}
[self.view.layer addAnimation:animation forKey:@"animation"];
}
-(void)selectMenuItemRight{
CATransition *animation = [CATransition animation];
animation.duration = 0.8;//动画时间
animation.type = @"cube";
animation.subtype = kCATransitionFromRight;//设置方向
UIButton *lastView = [self.view.subviews lastObject];//找到最上层的view
if (lastView.tag == 100) {
[self.view bringSubviewToFront:self.menuTwo];
}else if (lastView.tag == 101){
[self.view bringSubviewToFront:self.menuThree];
}else if (lastView.tag == 102){
[self.view bringSubviewToFront:self.menuOne];
}
[self.view.layer addAnimation:animation forKey:@"animation"];
}
最后把方法掉进VC里大家就可以看到效果了，好了大家赶紧去试试吧，第一次写，写的不好，希望大家多多指点， 谢谢大家了。
