[cocoa]_[primary]_[nstableview--data operation and table operation to be aware of issues]

1. First create a nstableview in the MainMenu.lib file, display a table on the interface, and set the table.

2. Create Files TableViewDelegate.h and TABLEVIEWDELEGATE.M (file contents as shown in the file below). and create an object in the MainMenu.lib file (select object from the right side of the window, and pull to the dialog box in window), named: Tableviewdelegate.

3. Set up proxy: TableView to set up and connect to the table view in the picture.

The Staticfield is connected to the Label control in the window.

DataSource and delegate agent to Tableviewdelegate.

(as shown)

The tabular data is consistent with the definition data.

The identifier of each column should be the same as the name of the variable defined in Mqjtabledata.

If the first column identifier is set to: Phoneid, the variable defined in Mqjtabledata is NSString *phoneid.

Other columns, likewise.

MqjTableData.h

#import <Cocoa/Cocoa.h> @interface mqjtabledata:nsobject{    nsstring *phoneid;    NSString *phonename;    NSString *phonenumber;} @property (readwrite,copy) nsstring *phoneid; @property (readwrite,copy) nsstring *phonename; @property (readwrite,copy ) NSString *phonenumber; @end

mqjtabledata.m

#import "MqjTableData.h" @implementation mqjtabledata@synthesize Phoneid; @synthesize phonename; @synthesize PhoneNumber; @end
