iOS 左滑功能 Swipe

 

method 1 - commitEditingStyle

這個method一定要複寫才會有功能出現

 

method 2 - canEditRowAtIndexPath

決定是否要出現左滑功能（要先有method 1)

 

method 3 - editActionsForRowAtIndexPath

若有自定義的功能，就得複寫這個method，但得連系統預設的功能也要一併複寫

也就是說複寫後連Delete也不見了，要一併再實作出來！

 

Objective-C

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{

}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView==self.categoryTableView){
return YES;
}else{
return NO;
}
}

- (NSArray *)tableView:(UITableView *)tableView
editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *moreAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"More" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// show UIActionSheet
}];
moreAction.backgroundColor = [UIColor greenColor];

UITableViewRowAction *flagAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"Flag" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
// flag the row
}];
flagAction.backgroundColor = [UIColor yellowColor];

return @[moreAction, flagAction];
}
