ios - View updates too late in Collection View after scrolling -


i have collectionview image inside each cell. when i'm scrolling collection, new cell (indexpath = 10) contains image old cell (indexpath = 1), calls method:

func collectionview(_ collectionview: uicollectionview, cellforitemat indexpath: indexpath) -> uicollectionviewcell {  }

and set image url new view. best way hide old image after scrolling before update?

you need clean images in collectionviewcell upon reusing them. override prepareforreuse function in collectionviewcell subclass.

  override func prepareforreuse() {         super.prepareforreuse()         // set cell's imageview's image nil         self.imageview.image = nil     }

i'm using dapper insert data realtime feed sql server, care performance. recently, noticed strange. out of box, if give dapper collection , insert query, fires insert statements each element. tests show can insert 1800 objects 12 fields in 1 second way (counting connection.execute(...) running time. now, didn't find batch insert functionality in dapper , implemented own (constructing parameter list , sql query). after that, found out can insert 1 batch in 3 seconds (which limited 1000 rows) (again, counting connection.execute(...) calls. so, makes batching 6 times slower sending each row in separate query. can explain me? thought people use batch operations speed process. insert time 1 second @ most. use sql server 2012 standard on local network. table i'm inserting has clustered index on primary key (which bigint field), no non-clustered indexes , triggers. can post code, there's nothing special i'm not sure why using dapper execute extension ...
