UIwindows 提示框动画显示以及隐藏关闭

最近做弹出相册选择等的弹出框，自己做了一个。互相学习一下。。。

直接上代码

@property (strong,nonatomic)UIWindow *windowButtonMineView;//悬浮

#pragma mark 修改图像响应方法

- (void)btnUserImageClick:(UIButton *)sender {

    _windowButtonMineView = [[UIWindowalloc] initWithFrame:CGRectMake(0,self.view.frame.size.height,self.view.frame.size.width,140)];

    _windowButtonMineView.windowLevel =UIWindowLevelAlert;

    //_windowButton.backgroundColor = [UIColor colorWithRed:233 green:233 blue:233 alpha:1.0];

    _windowButtonMineView.backgroundColor =ColorViewBackground;

    

    float btnWidth =_windowButtonMineView.frame.size.width,btnHeigth =40;

    UIButton *btnEditImage1 = [[UIButtonalloc] initWithFrame:CGRectMake(0,1, btnWidth, btnHeigth)];

    [btnEditImage1 setTitle:@"拍照"forState:UIControlStateNormal];

    [btnEditImage1 setTitleColor:ColorTextFondColorforState:UIControlStateNormal];

    btnEditImage1.backgroundColor = [UIColorwhiteColor];

    btnEditImage1.tag =2;

    [btnEditImage1 addTarget:selfaction:@selector(btnImageBackClickInMineView:)forControlEvents:UIControlEventTouchUpInside];

    [_windowButtonMineViewaddSubview:btnEditImage1];

    

    UIButton *btnEditImage2 = [[UIButtonalloc] initWithFrame:CGRectMake(0,42, btnWidth, btnHeigth)];

    [btnEditImage2 setTitle:@"从手机相册选择"forState:UIControlStateNormal];

    [btnEditImage2 setTitleColor:ColorTextFondColorforState:UIControlStateNormal];

    btnEditImage2.backgroundColor = [UIColorwhiteColor];

    btnEditImage2.tag =1;

    [btnEditImage2 addTarget:selfaction:@selector(btnImageBackClickInMineView:)forControlEvents:UIControlEventTouchUpInside];

    [_windowButtonMineViewaddSubview:btnEditImage2];

    

    

    UIButton *btnEditImage4 = [[UIButtonalloc] initWithFrame:CGRectMake(0,100, btnWidth, btnHeigth)];

    btnEditImage4.backgroundColor = [UIColorwhiteColor];

    [btnEditImage4 setTitle:@"取消"forState:UIControlStateNormal];

    [btnEditImage4 setTitleColor:ColorTextFondColorforState:UIControlStateNormal];

    [btnEditImage4 addTarget:selfaction:@selector(BtnCloseImageWindowsInMineView)forControlEvents:UIControlEventTouchUpInside];

    [_windowButtonMineViewaddSubview:btnEditImage4];

    

    

    //显示window

    [_windowButtonMineViewmakeKeyAndVisible];

    //设置动画结束

    [UIViewcommitAnimations];

}

#pragma mark 关闭windows视图
