I have a detail view controller which is pushed when a row is selected in a table view. When in a session the first time a row is selected it works fine. But when in the same session any row is selected there is a black screen behind all the content in the detail view controller which is pushed. And the scrolling of the uitextview also does not work
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSLog(@"selected");
NSDictionary *size = [[NSDictionary alloc] init];
size = [self sizeForLabelAtIndexPath:indexPath.row tableView:tableView andFeed:self.feedArray[indexPath.row]];
CGFloat sizes = ([size[@"messageHeight"] floatValue] + [size[@"nameHeight"] floatValue] + [size[@"imageHeight"] floatValue]);
sizes *= 1.05;
if (sizes<327) {
[self.tableView deselectRowAtIndexPath:indexPath animated:NO];
}else{
CellDetailViewController *cdvc = [self.storyboard instantiateViewControllerWithIdentifier:@"FacebookDetail"];
cdvc.sizeDictionary = [self sizeForLabelAtIndexPath:indexPath.row tableView:tableView andFeed:self.feedArray[indexPath.row]];
cdvc.feed = self.feedArray[indexPath.row];
[self.navigationController pushViewController:cdvc animated:YES];
}
}
