uiview with tap gesture action

BlockTapView

#import <UIKit/UIKit.h>

typedef void(^tapAction)(UITapGestureRecognizer *tap);

@interface BlockTapView : UIView

@property (copy) tapAction blockTapAction;

- (instancetype)initWithFrame:(CGRect)frame andAction:(tapAction)action;

@end


@implementation BlockTapView

- (instancetype)initWithFrame:(CGRect)frame andAction:(tapAction)action {

    if ((self = [super initWithFrame:frame])) {
        self.blockTapAction = action;
        
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTap:)];
        [self addGestureRecognizer:tap];
    }
    return self;
}

- (void)didTap:(UITapGestureRecognizer *)tap {
    if (self.blockTapAction) {
        self.blockTapAction (tap);
    }
}

@end

in DroppySection.m file, the init method registers a tap gesture to section view called sectionTapped:

- (instancetype)initWithHeaderView:(UIView *)headerView index:(NSInteger)index andPadding:(CGFloat)padding {
    if ((self = [super init])) {
        self.headerView = headerView;
        self.index = index;
        self.padding = padding;

        self.views = [[NSMutableArray alloc] init];
        self.expanded = NO;
        self.expanding = NO;

        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sectionTapped:)];
        [headerView addGestureRecognizer:tap];
        [headerView setUserInteractionEnabled:YES];
    }
    return self;
}


- (void)sectionTapped:(UITapGestureRecognizer *)tap {
    self.expanding = YES;
    self.expanded = !self.expanded;

    if (self.isExpanded) {
        [self expand];
    } else {
        [self collapse];
    }
}

i think button cant trigger because the tap gesutre catches the event first..
you can edit the sectionTapped: method for section tap event.
