网易新闻侧滑抽屉效果(利用父子控制器实现)
一:类似于网易的抽屉效果,启动有广告,进入主界面后,点击左上角按钮,侧滑左抽屉,点击右上角,侧滑出右抽屉。点击左抽屉按钮,对视图进行切换
。
二代码:
1:启动图展示广告界面实现:先吧启动图控制器作为窗口的根视图控制器,展示完广告消失后,再切换窗口的根视图控制器为主控制器。其中窗口指的是项目中的主窗口也就是keyWindow,主窗口主要负责接收一些键盘事件,文本框输入事件,若是键盘文本框,textView或是textfield不能输入,则考虑是不是当前窗口是否是主窗口
@interface HMAdViewController () @end @implementation HMAdViewController - (void)viewDidLoad { [super viewDidLoad]; // 1.背景图片 UIImageView *bg = [[UIImageView alloc] init]; bg.image = [UIImage imageNamed:@"Default"]; bg.frame = self.view.bounds; [self.view addSubview:bg]; // 2.广告图片(真实的广告图片应该要先下载广告图片) UIImageView *ad = [[UIImageView alloc] init]; ad.image = [UIImage imageNamed:@"ad"]; ad.width = 280; ad.height = 300; ad.centerX = self.view.width * 0.5; ad.y = 60; [self.view addSubview:ad]; // 3.2s后调到下一个主界面 dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(10.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ UIWindow *window = [UIApplication sharedApplication].keyWindow; UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; window.rootViewController = [storyboard instantiateViewControllerWithIdentifier:@"Main"]; }); } @end
2:当启动图广告界面展示完毕后,切换窗口根视图控制器。

三:知识点总结:
1:启动图的广告展示界面:1:创建启动图展示控制器,其中广告的图片一般是从服务器获取,搞个定时器,GCD延迟函数,经过一段时间后,再切换窗口的根视图控制器为主控制器。 UIWindow *window = [UIApplication sharedApplication].keyWindow;keyWindow为主窗口,负责键盘处理和文本框输入事件,若是textView,textField不能处理-输入事件,或是响应键盘则判断当前显示窗口是否是主窗口keyWindow。2:其中还可以通过keyWindow获取rootViewController,和当前显示的导航控制器,keyWindow.rootViewController, TabBarVC *tab = keyWindow.rootViewController; NAV *nav = tab.selecteViewcontroller;得到当前显示的导航控制器,nav.viewControllers,得到当前导航控制器栈里的所有控制器。
2:sattic const 定义常量来代替宏定义: static const CGFloat HMNavShowAnimDuration = 0.25;来代替 #define HMNavShowAnimDuration 0.25 ,因为static const定义的常量在系统中只会开辟一份内存,而#define,所定义的每一个常量都会开辟一份临时的内存空间。用static修饰的全局变量,只能是全局变量,该变量才会限制在本类中使用,外部不可以访问,若不加static,则用ertern,就可以在其他类中访问该变量。const在前在后都是一样的,定义字符串变量时,static NSString * const name = @"name";则指针name不可改变。const修饰变量或是常量时,就看const右侧是什么,则const右侧的指针或是变量不可改变。
3:创建子控制器addChildViewController:苹果官方建议当控制器互为父子关系时,控制器上的view也应该为父子关系。1:将创建子控制器的代码封装起来,创建子控制器对象,将子控制对象和title作为参数传入。2:titleView的封装:1:因为titleView为图片和文字构成,所以用button去封装titleView,创建控件继承UIButton,设置自身属性,btn的ennable,或是userenable为NO,titleLable.font,titleColor,setImage,btn.adjustImageWhenHeighlight(当setImage时),titleEdgeInsets,imageEdgeInset,contentEdgeInset,继承UIcontrol的contentHorizanAliment(整个btn文本的对其方式),btn的高度,self.height =self.currentImage.size.height;self.currentImage获得当前的image,btn.currentBackgroundImage,获得背景图片 2:懒加载子控件,添加到父视图上,无 3:layoutSubView布局子控件 4:向外界提供model接口,重写model的set方法,外界提供title接口,重写title的set方法,btn要设置自身的宽度自适应,用boundingRectWithSize,如下:
NSDictionary *attrs = @{NSFontAttributeName : self.titleLabel.font}; CGFloat titleW = [title boundingRectWithSize:CGSizeMake(MAXFLOAT, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:attrs context:nil].size.width; self.width = titleW + self.titleEdgeInsets.left + self.currentImage.size.width;
其中,只要赋值,就调用set方法,想获得此变量,就调用get方法,没必要再UIFont去设置,boundingRectWithSize,单行绘制文本时,两个参数都穿MAXFLOAT,基于基线绘制NSStringDrawingUsesLineFragmentOrigin,若是多行,则先设置lable.numberoflines = 0;再限制宽度或是高度,参数采用基线绘制,NSStringDrawingUsesLineFragmentOrigin,和行间距 NSStringDrawingUsesFontLeading。总的宽度就为,image的宽度+self.titleEdgeInsets.left+self.currentImage.size.width。其中titleEdgeInsets的设置,指的是距离左侧图片的距离,为正数,则指的是右侧距离
4:自定义导航栏上的左右item,自定义btn,btn setBackgroundImage,图片为按钮的背景图片,btn的大小为图片的大小, button.size = button.currentBackgroundImage.size;
5:封装导航控制器:1:继承系统导航控制器,因为设置全局导航栏的属性,只需设置一次就好,所以写在+ (void)initialize里,该方法只在该方法所在类第一个方法被调用之前被调用一次,只在整个项目中只会调用一次。先获得全局导航栏,item对象,利用settitleTextAttribute forState属性,可以设置不同状态下的属性 2:左右item距离屏幕左右边框的距离很大,想要调整,1:可遍历系统控件的子控件,找出左右按钮,再设置左右按钮的frame 2:自定义bar用kvc代替系统的bar:新建类继承系统的bar,在layoutSubView方法中,则子类继承了系统bar的属性,遍历子控件数组,self.subViews,在遍历时,要做条件过滤,不符合条件的直接return,或是continue。找到子控件的时候停止遍历,做性能优化。找到左右按钮后,判断左右按钮的btn的center与中点比较,看是哪个左右item。3:设置完frame之后,再在封装的nav控制器中创建对象,setValue forKeyPath ,kvc来代替系统的控件,第二个参数,就是nav控制器下属性定义的navBar,调用此方法,得是某个控制器下的某个属性
// 替换为自定义的导航栏 [self setValue:[[HMNavigationBar alloc] init] forKeyPath:@"navigationBar"];4:其中:layoutSubView方法只适用于在UIView中,在控制器中调整子控件可以重写系统方法:- (void)viewDidLayoutSubviews,但是不要忘记调用super
6:[self addChildViewController:nav];1:添加子控制器,能则父控制器就对子控制器有一个强引用,只要父控制器在,则子控制器就在,而且控制器互为父子关系,则他们的view也应该互为父子关系。2:子控制器数组:self.childViewControllers,得到子控制器数组,只读,子控制器从父控制器移除,subNav removeFromParentViewController ,获得父控制器:subNav.parentViewController
7:封装左侧菜单:1:有背景的话可以继承UIImageView,但要开启用户交互权限,也可以继承UIView,设置背景图片时,添加UIImageView,或是view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:]];,平铺图片,或有间隔线,或是调用drawInRect,画上一张图片 2:先设置自身的属性,clearcolor 3:懒加载控件,设置控件属性,添加到父视图上,创建相同的控件,例如button,可以采用for循环创建,也可以一个一个创建,传title,image,枚举tag值或是其他参数,封装一个button,创建对象,setImage,btn.adjust,setBackgroudImage,可以设枚举tag值,也可以通过设置self.subViews.count为tag值,也可以设置titleEdgeInset,ImageEdgeInset,contentEdgeInset,继承UIcontrol的也可以用contentHorizanAliment(文本的对齐方式),在layoutSubView里设置控件的frame,1:属性,成员变量 ,通过tag值取出,若是有多个子控件,可以设置tag值,遍历子控件数组,通过tag值将子控件取出2:放在大数组里,从数组里取出,若是又有button又有其他控件,则两两分别放在数组里,分别从数组里取出,设置frame 3:遍历subView,从subViews的数组里取出。4:设置按钮的回调:1:可通过协议代理,通知 ,block ,协议代理,block适用于层级较浅的回调,通知,多播委托适用于层级较深的结构 2 :若是监听系统的控件:继承UIControl的可以addTarget,可以系统的代理,系统通知,子类若没有查看父类,也可以重写系统的方法,不要忘记调用super方法,来实现监听 3:按钮的协议代理,传枚举tag值是为了在控制器实现监听点击,传fromIndex,传toIndex,是为了从数组取出旧的移除,并添加新的 4:按钮的回调方法,两个按钮状态的判断,btn.selected = !btn.isSelected,三个按钮切换状态则用按钮三部曲,若是传index则把代理方法放前面 5:设置按钮默认选中:1:直接设哪个按钮被选中,再设seletedBtn 2:返回按钮,调用按钮的点击方法,要考虑需不需要重写代理的setDelegate方法在该方法中设置按钮的默认选中。
8:transform属性:1:当点击左上角按钮的时候,先进行缩放,在进行平移,在缩放的基础上进行平移,求缩放比例:缩放后的高度 = 屏幕高度 - 上下间距 ,用缩放的高度与原高度的比值就是缩放比例,在UIView的动画中先进行缩放,再在缩放的基础上进行平移,平移的距离,1-缩放比例,就为剩下的长度比例,0.5倍,就是缩放后的view的实际距屏宽度。2:在动画结束的时候设置一个遮盖效果,遮盖效果:1:可以为一个view,添加手势,2:也可以另遮盖为一个button,监听button的点击事件,button在此处不能为成员变量,button的点击事件中,动画先将transform清空,完成时,将button从父视图移除。3:监听点击事件:1:继承UIControl的可以addTarget 2:添加手势监听器 3:实现touch beagn,touch end,touch cancle 方法,配合UITouch,使用,UITouch *touch = [UITouch anyObject]; touch.view可以获得触摸点点击的view,CGPoint point = [touch locationInView:touch.view];此方法可获得触摸点,其中触摸点的是基于touch.view来计算的,如果此参数填父视图view,则是基于整个父视图来计算的。然后一般是遍历数组,做条件过滤,利用CGRectContainPoint方法,根据触摸点求出矩形框的rect,找到结果后停止遍历 4:transform是二维旋转,view的图层layer是三维动画,view.layer.transform = CAAFfitransform(,,,,);最后三个参数为xyz轴,若是010,则是绕着y轴上1点与原点连线的的向量旋转,第一个参数为旋转的角度。5:动画效果:1:二维动画:UIView + transform 2:三维动画:UIView +view.layer.transform = CAAFi ,注意三个参数 3:转场动画:也就是翻转动画,[UIView transition...];翻转动画有各种参数值 4:三维动画也可以用CATranstion,CATranstion *ad = [CATranstion animation];ad.duration 动画时间,ad.type,动画的方式,字符串,[self.iconaImageView.layer addAnimation: ad forkey:nil];
9:监听左侧菜单按钮的回调事件:效果是,点击左侧按钮,切换视图,动画清空transform。将旧的控制器取出,view从父视图上移除,再将新控制器取出,将新控制器的view添加到父视图上,此时可以不必设置新view的frame,默认为父视图的bounds。将旧控制器的transform赋值给新的控制器的transform,更新当前的控制器,动画回去,此时就是清空新控制器的transform,相当于点击了旧控制器的遮盖,将按钮从父视图上取出,调用按钮点击方法。
10:在使用xib绘制界面的时候,有时明明尺寸设置正确,但是就不能正常显示,1:此时可以禁用autoLayout 2:setNeedsLayOut ,layOutIfNeed配合使用,异步调用layoutSubView,重新计算尺寸。3:当xib加载完毕后会调用awakeFromNib,在此方法中可以设置xib中控件的一些属性,当xib中已经设置了控件的尺寸,在外部依然可以修改xib中控件的尺寸
11:右侧菜单的封装设计:1:对于控制器和view来说,要采取分层封装的思想,就是将view和或是控制器切分成一个个模块,将零散的控件封装在一个整体内,然后再考虑整个项目中其他地方有没有用到,若用到则考虑继承关心A继承B,或是B继承A,或是将AB公共部分抽成父类C,AB分别继承父类C,不同的部分在AB中单独实现 2:右侧的菜单封装,可以采取三种封装方法:1:看成是一个tableView,table的headerView,tableView,table的footerView 但是没有cell的复用,且按钮的回调监听,太复杂 2:还可以考虑封装一个大view,再将上中下封装为三个小view添加到大view上,但是同样涉及的问题就是按钮的监听回调太麻烦 3:考虑用一个控制器,在控制器内实现按钮的监听,在控制器内再将整体封装为上中下三个view。2:对于顶部view的封装以及动画,顶部view中的头像的翻转就用转场动画,每执行一次转场动画,转360度,并更换图片,动画完成时,执行GCD延迟函数,在执行一个转场动画转回来,再更改frame 3:中间View的封装,按钮会点亮,调用的是button的btn.showTouchWhenHeighlight。此方法若是button有图片,则只在button的图片处点亮,再将每一行封装为一个View,点图片和箭头都会亮,则其肯定为一个整体,所以可以考虑button为整个背景,将图片和箭头添加到button上,因为当点击图片和箭头时,默认没有开启用户的交互权限,通过的事件的传递可以找到触摸点所在的view,但是该view不能处理事件,则事件会又子控件传递给父控件去处理,也就是交给button去处理,buttonn能处理所以点击图片箭头都会被点亮 4:设置每个封装view的y值,view.y = self.subViews.count *height;总高度,self.subViews.count *height
