IOS项目之弹出动画一

小区宝首页导航栏左边有一个物业按钮，点击时会出现一个视图动画,之前用的是一个POP第三方,想着几个POP动画就要引用一堆的第三方有点麻烦，就试着自己写了一下，功能实现了，下一步就是优化将其封装一下。下面我用DatePicker做的主要是想着再做出点击弹出按钮在底部出现DatePicker选择器。

    [super viewDidLoad];
//    self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"预览" style:UIBarButtonItemStyleDone target:self action:@selector(rightClick)];
    self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@"弹出" style:UIBarButtonItemStyleDone target:self action:@selector(leftClick)];

    //遮罩层
    _myview=[[myView alloc]initWithFrame:CGRectMake(,-self.view.bounds.size.height, self.view.bounds.size.width, self.view.bounds.size.height)];
    _myview.backgroundColor = [UIColor colorWithWhite:0.5 alpha:0.1f];
    //为遮罩层添加手势识别 可以点击遮罩层空白处隐藏视图
    UIGestureRecognizer *tapgesture=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapclick)];
    _myview.userInteractionEnabled=YES;
    [_myview addGestureRecognizer:tapgesture];

    //设置DatePicker
    _dataPicker=[[UIDatePicker alloc]init];
    _dataPicker.frame=CGRectMake(, , , );
//    datepicker.backgroundColor=[UIColor grayColor];
    [_myview addSubview:_dataPicker];

    //设置DatePicker上面的视图
    UIView *view=[[UIView alloc]initWithFrame:CGRectMake(, , self.view.bounds.size.width, )];
    view.backgroundColor=[UIColor blueColor];

    //下落动画 时间短一些

我们稍加改动就可以变成从底部弹出视图 这样就完成了闪购模块 宝贝详情中的选择规格的功能

上面的导航控制器并未被遮罩 ,这样添加时才能使导航控制器遮罩[[UIApplication sharedApplication].keyWindow  addSubview:_myview];
