How to display swipe button in uitableviewcell by tap on cell? - ios

Question

I have tried to call the functions manually by programming, those functions are
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES; //tableview must be editable or nothing will work...
}
When i call the functions it works inside the functions for example the editActionsForRowAtIndexPath function but doesnt show the button.
Any clue or help will be highly appreciated.

Answer 1

Did you forgot to call [self.tableView setEditing:YES animated:YES]; ?

Answer 2

Why do you use above 3 methods for swipe and deleting the table view cell?
Only one method is enough for doing this.I created sample one for your question.It works fine.
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
#property (nonatomic, strong) IBOutlet UITableView *tableViewEdit;
#end
ViewController.m
#import "ViewController.h"
#interface ViewController (){
NSMutableArray *arr;
}
#end
#implementation ViewController
#synthesize tableViewEdit;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
arr = [[NSMutableArray alloc]initWithObjects:#"iOS",#"Android",#"Windows",nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//UITableViewDataSource methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return arr.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *strCell = #"cell";
UITableViewCell *cell = [tableViewEdit dequeueReusableCellWithIdentifier:strCell];
if(cell == nil){
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strCell];
}
cell.textLabel.text = arr[indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if(editingStyle == UITableViewCellEditingStyleDelete)
{
[arr removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
}
}
When I run the application first it shows the below data
Then when I swipe the table view
Finally I delete the data from the table view and the table view
