IOS TableView implements the single-select Checkmark feature

I believe that when you do the project has encountered the need to implement this function---to achieve a single selection of a cell indicates the selected

The implementation of this feature only requires code in two methods

Preferred we expose a property

@property(nonatomic, strong)Nsindexpath *lastpath, and to its synthesize

is primarily used to receive the Indexpath of the user's last selected cell

The first step: Implement the following code in the Cellforrowatindexpath: method

-(UITableViewCell *) TableView: (uitableview *) TableView Cellforrowatindexpath: (nsindexpath *) indexpath{

Nsinteger row = [Indexpath row];

Nsinteger oldrow = [lastpath row];

if (row = = Oldrow && lastpath!=nil) {

Cell. accessorytype = Uitableviewcellaccessorycheckmark;

}else{

Cell. accessorytype = Uitableviewcellaccessorynone;

}

}

Step Two: Implement the following code in Didselectrowatindexpath:

-(void) TableView: (uitableview *) TableView Didselectrowatindexpath: (nsindexpath *) indexpath{ 　

int newRow = [Indexpath row];

int oldrow = (lastpath! = nil)? [ Lastpath row]:-1;

if (newRow! = Oldrow) {

UITableViewCell *newcell = [TableView cellforrowatindexpath:indexpath];

Newcell. accessorytype = Uitableviewcellaccessorycheckmark;

UITableViewCell *oldcell = [TableView cellforrowatindexpath:Lastpath];

Oldcell. accessorytype = Uitableviewcellaccessorynone;

Lastpath = Indexpath;

}

[TableView deselectrowatindexpath: Indexpath animated:YES];

}

Ok, it's time to call it off, so the effect is that each click of a cell will make a selected flag and the checkmark will not be reused when the table view is moved.

Hope to be helpful to beginners!
