trouble with deleting uitableview rows by default method

Question

This UITableViews gonna make me crazy!

I have UITableViewCell created by

- (UITableViewCell *)tableView:(UITableView *)tableView 
cellForRowAtIndexPath:(NSIndexPath *)indexPath {

doneButton = [[UIButton alloc]initWithFrame:CGRectMake(7, 15, 30, 30)];
[cell addSubview:doneButton];

cell.selectionStyle = UITableViewCellSelectionStyleNone;
[doneButton addTarget:self action:@selector(done:) forControlEvents:UIControlEventTouchDown];

UILabel *postedTime = [[UILabel alloc]initWithFrame:CGRectMake(240, 4, 60, 15)];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
postedTime.backgroundColor = [UIColor clearColor];
[cell addSubview:postedTime];
cell.textLabel.textColor = [UIColor blackColor];

UILabel *post = [[UILabel alloc] initWithFrame:CGRectMake(45, 25, 190, 30)];
[cell addSubview:post];

UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(45, 4, 180, 15)];
[cell addSubview:title];

mission *m = (mission *)[missionsArray objectAtIndex:indexPath.row];
title.text = m.title;
post.text = m.post;
postedTime.text = m.posted;

.h file:

IBOutlet UITableView *table;
NSMutableArray *missionsArray;

I'm trying to delete row by method

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [missionsArray removeObjectAtIndex:indexPath.row];
        [table reloadData];
}

And when I click "Delete" button EXC_BAD_ACCESS. I've tried to call [missionsArray removeAllObject]; -- the same error. Then I've tried to NSLog(@"%u", indexPath.row); -- it prints right rows (when I select first row, it returns 0 and so on). Also I've tried this

if (editingStyle == UITableViewCellEditingStyleDelete) {
        [missionsArray removeObjectAtIndex:indexPath.row];
        [table deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
        [table reloadData];
}

And I have no good result. Maybe cell height affects to it... Help, please. I have no idea what to do, where to search.
