ios - 通过导航栏查看部分内容(类似 Feedly 应用程序)

Question

我有一个可以与过滤器一起订购的 UITableView。我不想使用模态视图，而是只想制作一个来自屏幕左侧并部分覆盖我的 tableView 的 View 的动画。

这是我希望“过滤器 View ”看起来像的示例:

没有过滤器:

使用过滤器:

有什么办法？

Answer 1

使用可重用代码的正确方法:

将动画类别添加到UIView

@interface UIView (MyAnimation)
-(void)slideInWithDuration:(NSTimeInterval)duration;

//implementation

-(void)slideInWithDuration:(NSTimeInterval)duration
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    float nSpace = 0.0f //put any value you think right
    CGFloat extraOffset = self.view.frame.size.width / 2 + nSpace;

    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"];
    animation.fromValue = [NSValue valueWithCGPoint:CGPointMake(screenRect.origin.x - extraOffset, self.view.center.y)];
    animation.toValue = [NSValue valueWithCGPoint:self.view.center];
    animation.duration = duration;
    animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

    [self.layer addAnimation:animation forKey:@"SlideInAnimation"];
}

在 SomeWhereViewController.m 中

UIWindow *mainWindow = [[UIApplication sharedApplication] keyWindow];
UIView *someView = [[UIView alloc] init];
someView.frame = // customize to your like
[mainWindow addSubview:someView];

[someView slideInWithDuration:0.7];

希望对您有所帮助!
