2. Move Cells

// Trigger event to complete the move. Do not add this method and do not implement the move function.

-(Void) tableView :( UITableView *) tableView moveRowAtIndexPath :( NSIndexPath *) sourceIndexPath

ToIndexPath :( NSIndexPath *) destinationIndexPath

{

NSDictionary * item = [dataArr objectAtIndex: sourceIndexPath. row];

[DataArr removeObjectAtIndex: sourceIndexPath. row];

[DataArr insertObject: item atIndex: destinationIndexPath. row];

}

// Trigger event for mobile completion. If this method is not added, the mobile function is not implemented-(void) tableView :( UITableView *) tableView moveRowAtIndexPath :( NSIndexPath *) sourceIndexPath toIndexPath :( NSIndexPath *) destinationIndexPath {NSDictionary * item = [dataArr objectAtIndex: sourceIndexPath. row]; [dataArr removeObjectAtIndex: sourceIndexPath. row]; [dataArr insertObject: item atIndex: destinationIndexPath. row];}

3. Add cells. The following is a custom trigger event, that is, click the add button in the lower left corner.

Cpp Code

-(IBAction) addistItem :( UIBarButtonItem *) sender {

AppUtils * appUtils = [AppUtils alloc];

// Initialize a UIAlertView first.

UIAlertView * alert = [UIAlertView alloc];

[AppUtils showInputDialogWithTitle: @ "add" message: @ "please input new user name:" toAlertView: alert confirmAction :( ^ {

// Obtain the input box

UITextField * textField = [alert textFieldAtIndex: 0];

// Do not write it as NSMutableDictionary * newItem = [NSDictionary dictionary];

NSMutableDictionary * newItem = [NSMutableDictionary dictionary];

[NewItem setObject: textField. text forKey: @ "itemName"];

[NewItem setObject: @ "1.jpeg" forKey: @ "itemImagePath"];

[DataArr addObject: newItem];

[Self. tableView reloadData];

})];

}

-(IBAction) addistItem :( optional *) sender {AppUtils * appUtils = [AppUtils alloc]; // You Need to initialize a UIAlertView * alert = [UIAlertView alloc]; [appUtils failed: @ "add" message: @ "please input new user name:" toAlertView: alert confirmAction :( ^ {// get the input box UITextField * textField = [alert textFieldAtIndex: 0]; // do not write NSMutableDictionary * newItem = [NSDictionary dictionary]; NSMutableDictionary * newItem = [NSMutableDictionary dictionary]; [newItem setObject: textField. text forKey: @ "itemName"]; [newItem setObject: @ "1.jpeg" forKey: @ "itemImagePath"]; [dataArr addObject: newItem]; [self. tableView reloadData];})];}

4. AppUtils class attached

Cpp Code

# Import "AppUtils. h"

# Include "RIButtonItem. h"

# Include "UIAlertView + Blocks. h"

@ Implementation AppUtils

// The trigger event that pops up the alarm box and implements the alarm box button

-(Void) showInputDialogWithTitle :( NSString *) title message :( NSString *) message toAlertView :( UIAlertView *) alert confirmAction :( void (^) (void) action {

RIButtonItem * cancelItem = [RIButtonItem item];

CancelItem. label = @ "No ";

CancelItem. action = ^

{

// Processing when the value is NO

UITextField * tf = [alert textFieldAtIndex: 0];

NSLog (@ "UITextField = % @", tf. text );

};

RIButtonItem * confirmItem = [RIButtonItem item];

ConfirmItem. label = @ "Yes ";

// ConfirmItem. action = action;

Alert = [alert initWithTitle: title

Message: message

CancelButtonItem: cancelItem

OtherButtonItems: confirmItem, nil];

Alert. alertViewStyle = UIAlertViewStylePlainTextInput;

ConfirmItem. action = action;

[Alert show];

}

@ End

# Import "AppUtils. h "# include" RIButtonItem. h "# include" UIAlertView + Blocks. h "@ implementation AppUtils // a warning box is displayed, and the trigger event (void) showInputDialogWithTitle :( NSString *) title message :( NSString *) message toAlertView :( UIAlertView *) is implemented *) alert confirmAction :( void (^) (void) action {RIButtonItem * cancelItem = [RIButtonItem item]; cancelItem. label = @ "No"; cancelItem.
