UPDATE, insert TableView a row of data or section data

First, refresh the list

When a row of TableView data is modified, the data needs to be updated. There are two methods of refreshing:

(1) Refresh the entire list, that is, [self. TableView  reloaddata];

(2) Only the changed line is refreshed. Of course, this method is more efficient than the first method.

Specific code:

nsindexpath *refreshcell = [Nsindexpath indexpathforrow : 3 insection:0];

[ self. TableView reloadrowsatindexpaths: [nsarrayarraywithobjects: Refreshcell,nil] withrowanimation: Uitableviewrowanimationnone];

Second, insert a row of data data

Nsindexpath *refreshcell = [nsindexpathindexpathforrow: 3 insection : 0 ];

nsarray *insertindexpaths = [Nsarray Arraywithobjects:refreshcell,nil];

/// Also, add data to the data list

[_metermodelarray insertobject:d evice atindex : i+ 1 ];

[ self. TableView insertrowsatindexpaths: insertindexpathswithrowanimation: Uitableviewrowanimationright];

Third, refresh the data of a section

Nsindexset *refreshsection=[[nsindexsetalloc]initwithindex: 1]; // Refresh a second Section

[ self. TableView reloadsections: refreshsection withrowanimation: Uitableviewrowanimationautomatic];

iv. inserting a section data

According to the above, you can change it, no longer write.
