Smooth reload of uitableview data when rows are deleted?
Delete the data from the data source in tableView delegate (void) tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { NSString *key = keys objectAtIndex:indexPath. Section; NSMutableArray *nameSection =names objectForKey:key; int itemID=item. ID; if (nameSection count==1) { self.
Keys removeObjectsInArray:NSArray arrayWithObject:key; tableView deleteSections:NSIndexSet indexSetWithIndex:indexPath. Section withRowAnimation:UITableViewRowAnimationFade; } else { nameSection removeObjectAtIndex:indexPath. Row; self.
Names setValue:nameSection forKey:key; tableView deleteRowsAtIndexPaths:NSArray arrayWithObject:indexPath withRowAnimation:UITableViewRowAnimationFade; } } check this too.

The thing is I would just know which indexes from the data source array I want to delete, so I think the above solution wouldn't work. The user is not deleting the rows himself. – Praveen S Jul 6 at 8:48 if you datasource is array you may know the index of the object removing from array.
Create index path using this index. NSIndexPath *indexPath = NSIndexPath indexPathForRow:0 inSection:0; tableView deleteRowsAtIndexPaths:NSArray arrayWithObjects:indexPath,nil withRowAnimation:UITableViewRowAnimationFade; – Dileep Reghu Jul 6 at 8:59 I will try this and update here. I may have to screw up my MVC a little here to get the indexes.

I am trying to reload a uitableview when it scrolls to the bottom of the screen. I delete the first few rows and add more rows to the bottom. Before the news rows are added to the uitableview's data source, I call the tableview reloaddata method.
This is because I want the tableview to display the row which were previously visible on it. It reloads the data correctly but there is a sudden jerk in the tableview. It flashes which doesn't give a nice user experience.
The current visible row should be retained in the refreshed view also. There are no crashes as I update the data source correctly.
Many foods can cause kidney stones. Some are rhubarb, sweet potatoes, black tea, beets, chocolate, peanuts, okra, soybean crackers, marmalade, grits, wheat germ, grapes, strawberries, celery and fruit cake.
Nephrolithiasis, or more commonly, kidney stones affect nearly 400,000 people a year according to Nutrition and Diagnosis-Related Care. Approximately 75 to 80 percent of stones are composed of calcium oxalate, with the remaining stones being composed of struvite, uric acid and a very small proportion from ammonium acid urate. The stones can be caused by medications, fluid status, metabolic disorders and food intake.
Even though most stones are calcium oxalate, high oxalate foods are more likely the cause. Other dietary factors such as high sodium and caffeine are also associated with increased risk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
