Filter with own way !

Youtube : https://www.youtube.com/watch?v=KUN6bs9pl74&feature=youtu.be

FeSlideFilterView is subclass UIView. Bring new way to display your photo.

You can slide between filter by your touch. Gain more User Exp than nomal way.

So You must ensure your project has iOS version more than iOS 7.0.

And compatible with ARC or non-ARC.

In Sample code, I user LUT technique to apply filter to photo.

More info, visist my blog : http://nghiatran.me/index.php/filter-me-color-lookup-table-part-2/

If you wanna use LUT, please sure you added Core Image and OpenGL ES framwork to your project.

FeSlideFilter use Data Source / Delgate pattern like UITableView.

Just provide filtered UIImage

and Title for each Filter.

Ex :

// Number of filter
-(NSInteger) numberOfFilter
{
    return 5;
}

// Title for filter at index
-(NSString *) FeSlideFilterView:(FeSlideFilterView *)sender titleFilterAtIndex:(NSInteger)index
{
    return _arrTittleFilter[index];
}

// Filtered UIImage at index
-(UIImage *) FeSlideFilterView:(FeSlideFilterView *)sender imageFilterAtIndex:(NSInteger)index
{
    return _arrPhoto[index];
}

If you want to customize by yourself. Just assign your button with _doneBtn property.

// Btn
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(0, 0, 40, 40);
    [btn setBackgroundImage:[UIImage imageNamed:@"done"] forState:UIControlStateNormal];
    
    _slideFilterView.doneBtn = btn;
    

======================

You can change behavior by changing 3 properties when init

Data Source :

@required
// Number of filter
-(NSInteger) numberOfFilter;

// Title filter at index
-(NSString *) FeSlideFilterView:(FeSlideFilterView *) sender titleFilterAtIndex:(NSInteger) index;

// Image at index
-(UIImage *) FeSlideFilterView:(FeSlideFilterView *) sender imageFilterAtIndex:(NSInteger) index;

@optional
// Font at index
-(UIFont *) FeSlideFilterView:(FeSlideFilterView *) sender fontForTitleAtIndex:(NSInteger) index;

// Layer's content Gravity
-(NSString *) kCAContentGravityForLayer;

Delegate :

// Call when user tapped Btn
-(void) FeSlideFilterView:(FeSlideFilterView *) sender didTapDoneButtonAtIndex:(NSInteger) index;

// Determine when user can slide
-(BOOL) FeSlideFilterView:(FeSlideFilterView *)sender shouldSlideFilterAtIndex:(NSInteger) index;

// Call when user have just slided
-(void) FeSlideFilterView:(FeSlideFilterView *)sender didBeginSlideFilterAtIndex:(NSInteger) index;

// Call when user end Slide
-(void) FeSlideFilterView:(FeSlideFilterView *)sender didEndSlideFilterAtIndex:(NSInteger) index;
