Duplicate of actions UIView with UITableView - ios

Question

I have table in main view. Next I added view to above table view with height 100 points, then I have first row with 100 points height. Next I check scrollView contentOffset to recalculate position of my added view. When I scroll my table view all fine, my view is duplicate position with my first cell in table view.
But I have problem is:
When I want to scroll from my view (finger in a view) and scroll down, table view is no interaction with my gestures. Yes, that normal. If I set user interaction to NO, all work fine. But I have some buttons in this view and when I disabled user interaction I can't have actions with my subviews in this view.
How I can scroll and tap simultaneously/together without user interaction or something else method. Thx.
All of code:
#import "ViewController.h"
#interface ViewController () <UITableViewDataSource, UITableViewDelegate>
{
UIView *someView;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UITableView *tableView = [[UITableView alloc] initWithFrame:self.view.bounds];
tableView.dataSource = self;
tableView.delegate = self;
[self.view addSubview:tableView];
someView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100)];
someView.backgroundColor = [UIColor redColor];
[self.view addSubview:someView];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 10;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(nonnull NSIndexPath *)indexPath{
if (indexPath.row == 0) return 100;
else return 44;
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
if (indexPath.row == 0) cell.backgroundColor = [UIColor greenColor];
}
return cell;
}
-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
someView.center = CGPointMake(someView.center.x, -scrollView.contentOffset.y+50);
}

Answer 1

Try to add button on main view
- (void)viewDidLoad {
[super viewDidLoad];
UITableView *tableView = [[UITableView alloc] initWithFrame:self.view.bounds];
tableView.dataSource = self;
tableView.delegate = self;
[self.view addSubview:tableView];
someView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100)];
someView.backgroundColor = [UIColor redColor];
[self.view addSubview:someView];
UIButton *someBotton = [UIButton buttonWithType:UIButtonTypeCustom];
// button initialisation
...
[self.view addSubview:someBotton];
}
In this case table will not interact only below button
Second way is create subclass for someView and override method pointInside:
- (BOOL)pointInside:(CGPoint)point withEvent:(nullable UIEvent *)event{
for(UIView *subview in self.subviews){
if([subview pointInside:point withEvent:event]){
return YES;
}
}
return NO;
}
