insertRowsAtIndexPaths or reloadData doesn't respond - ios

Question

Here is my code. And yesterday it works just fine. But this morning, it doesn't work.
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 0) {
RSDrug *drug = [[RSDrug alloc]init];
[drugArray insertObject:drug atIndex:0];
NSIndexPath *ip = [NSIndexPath indexPathForRow:1 inSection:0];
[tableView insertRowsAtIndexPaths:#[ip] withRowAnimation:UITableViewRowAnimationAutomatic];
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return drugArray.count + 1;
}
I have tried to add some code like beginUpdates/endUpdates, or I delete insertRowsAtIndexPaths, just use reloadData.
But same result. When the app runs to insertRowsAtIndexPaths or reloadData, it stuck, no response.
So I need some help. How to solve this?
Found the problem..........A stupid mistake
There are two UITextFields in the added cell, and they all have the same leftView, my code is like this:
UIImageView *leftImage = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"img"]];
field_1.leftView = leftImage;
field_2.leftView = leftImage;
I never know that I can't reuse the leftView. If I set the leftImage to field1, I can't set it to field2 anymore.
When I changed to this, it works again.
field_1.leftView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"img"]];
field_2.leftView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"img"]];

Answer 1

Try this sequence...
NSMutableArray *indexPaths=[[NSMutableArray alloc]init];
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[tableView beginUpdates];
RSDrug *drug = [[RSDrug alloc]init];
[drugArray insertObject:drug atIndex:0];
if (indexPath.row == 0) {
[indexPaths removeAllObjects];
[indexPaths addObject:[NSIndexPath indexPathForRow:indexPath.row++ inSection:0]]; // here inserting row index=1;
[tableViewMenuList insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];
}
[tableView endUpdates];
}

Answer 2

Have you tried this?
RSDrug *drug = [[RSDrug alloc]init];
[drugArray insertObject:drug atIndex:0];
[tableView beginUpdates];
// indexpath inserted is with the index 0 same with the `insertObject: `
NSIndexPath *ip = [NSIndexPath indexPathForRow:0 inSection:0];
[tableView insertRowsAtIndexPaths:#[ip] withRowAnimation:UITableViewRowAnimationAutomatic];
//here is what i use to do instead of #[]
//[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:ip] withRowAnimation:UITableViewRowAnimationAutomatic];
[tableView endUpdates];
EDIT
Your code are working fine. i tested it. here..
Code:
Output:
Log:
Check the tested code above if you have omitted something.
I think the problem is the delegates of your table, make sure that your table have the delegate for both UITableViewDataSource & UITableViewDelegate.
Hope this is helpful.. Cheers.. :)
