Question

I have a UITableView that can be ordered with filters.
Instead of using a modal view i wanted to just make an animation of a view comming from the left of the screen and partially covering my tableView.

Here is an exemple of what i want my “filters view” to look like :

Without the filter :

With the filter :

What could do the trick ?

Answer 1

The proper way, with reusable code:

add Animation category to 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"];
}

in SomeWhereViewController.m

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

[someView slideInWithDuration:0.7];

Hope that helps!
