Swift iOS how selected data to a table

问题

How do I do it when if status is equal to static I don't want to show it in the table? Code is below. I only wanted to show all the data but not the data with status == "static".

Response [["status": {
    name = static;
}, "sched": 2015-01-01T08:00:00+08:00, "desc": Brush your teeth, "id": 249, "reward": 1.00, "parent": , "child": , "date_created": 2018-04-25T14:27:20.405928+08:00, "name": aBrush your teeth, "occurrence": {

回答1:

Firstly, you should not create a cell if you don't want to show it. If you are, you are making unnecessary extra calls.

If you are currently returning the total count of your datasource at numberOfRowsInSection, you must return the count of items with status != "static" instead. This way the cellForRowAt will be called the correct amount of times.

Then, you have 2 options:

Have a separate datasource which doesn't contain items with status == "static" and use it directly at cellForRowAt;
Filter, at cellForRowAt, your current datasource, so that it returns only the correct items.

Before passing data to tableview methods, you must have to remove entries from getTempDetails dictionary which you don't want.. means create same dictionary with removing data where name == "static"... and use newly created dictionary for table
