本文实例为大家分享了ios多控制器实现带滑动动画的具体代码，供大家参考，具体内容如下
主控制器 ,管理控制器 .h文件
//宏 #define kscreenwidth [uiscreen mainscreen].bounds.size.width #define kscreenheight [uiscreen mainscreen].bounds.size.height #import "mymainviewcontroller.h" #import "myfirstviewcontroller.h" #import "mysecondviewcontroller.h" #import "mythirdviewcontroller.h" @interface mymainviewcontroller ()<uiscrollviewdelegate> //控制器名 @property (nonatomic, strong) nsarray *vcnames; //选择栏 @property(nonatomic, strong) uiview *clickbar; //底部容器scrollview @property (strong, nonatomic) uiscrollview *containerscrollerview; @end
. m 文件
底部scrollview , 用于滑动
我要评论
@implementation mymainviewcontroller
- (uiscrollview *)containerscrollerview
{
if (!_containerscrollerview) {
_containerscrollerview = [[uiscrollview alloc]init];
_containerscrollerview.pagingenabled = yes;
_containerscrollerview.showsverticalscrollindicator = no;
_containerscrollerview.showshorizontalscrollindicator = no;
_containerscrollerview.contentsize = cgsizemake(kscreenwidth *self.vcnames.count,kscreenheight);
_containerscrollerview.backgroundcolor = [uicolor whitecolor];
_containerscrollerview.delegate = self;
}
return _containerscrollerview;
}
初始化顶部选择栏
//三个子控制器
- (nsarray *)vcnames
{
if (!_vcnames) {
_vcnames = @[@"控制器一",@"控制器二",@"控制器三"];
}
return _vcnames;
}
//点击选择栏
- (uiview *)clickbar
{
if (!_clickbar) {
_clickbar = [[uiview alloc]init];
_clickbar.backgroundcolor = [uicolor lightgraycolor];
cgfloat width = kscreenwidth / 3;
cgfloat height = 44;
//初始化按钮
for (nsinteger index = 0; index < 3; index++) {
uibutton *button = [uibutton buttonwithtype:uibuttontypecustom];
[button settitle:self.vcnames[index] forstate:uicontrolstatenormal];
[button settitlecolor:[uicolor bluecolor] forstate:uicontrolstatenormal];
button.frame = (cgrect){width *index,0,width,height};
[button addtarget:self action:@selector(buttonclick:) forcontrolevents:uicontroleventtouchupinside];
//绑定tag值
button.tag = index;
[_clickbar addsubview:button];
}
}
return _clickbar;
}
viewdidload
- (void)viewdidload {
[super viewdidload];
self.edgesforextendedlayout = 0;
//初始化选择栏
[self initclickbar];
//初始化底部scrollview容器
[self initscrollviewcontainer];
//初始化子控制器
[self addchildcontrollers];
}
添加子控制器 , 初始化ui
//按钮选择栏
- (void)initclickbar
{
[self.view addsubview:self.clickbar];
self.clickbar.frame = (cgrect){0,0,[uiscreen mainscreen].bounds.size.width,44};
}
//初始化滑动容器
- (void)initscrollviewcontainer
{
[self.view addsubview:self.containerscrollerview];
self.containerscrollerview.frame = cgrectmake(0,44,kscreenwidth, kscreenheight );
}
//添加子控制器
- (void)addchildcontrollers
{
//为了方便直观 , 在此处设置背景色 (实际开发中,不能在这里设置 , 原因是这里只要调用到了控制器的view属性 , 该控制器将会执行viewdidload方法 , 相当于直接一开始就将三个控制器的所有ui和网络请求全加载完了 , 负荷会相当重)
myfirstviewcontroller *firstvc = [[myfirstviewcontroller alloc]init];
firstvc.view.backgroundcolor = [uicolor redcolor];
[self addchildviewcontroller:firstvc];
mysecondviewcontroller *secondvc = [[mysecondviewcontroller alloc]init];
secondvc.view.backgroundcolor = [uicolor bluecolor];
[self addchildviewcontroller:secondvc];
mythirdviewcontroller *thirdvc = [[mythirdviewcontroller alloc]init];
thirdvc.view.backgroundcolor = [uicolor yellowcolor];
[self addchildviewcontroller:thirdvc];
//默认展示第一个子控制器
[self scrollviewdidenddecelerating:self.containerscrollerview];
}
按钮点击事件实现 , 代理方法实现
//选择栏按钮点击事件
- (void)buttonclick:(uibutton *)button
{
[self.containerscrollerview setcontentoffset:cgpointmake(button.tag *kscreenwidth, 0) animated:yes];
}
//滑动减速时调用
- (void)scrollviewdidenddecelerating:(uiscrollview *)scrollview
{
//获取contentoffset
cgpoint currentoffset = scrollview.contentoffset;
nsinteger page = currentoffset.x / kscreenwidth;
//取出对应控制器
uiviewcontroller *viewcontroller = self.childviewcontrollers
