默認TableView每個Cell之間的分割線樣式:

注意左側,Separator與屏幕左側存在一定間距,如果我們希望左右兩邊都對齊屏幕,可以嘗試重寫viewDidLayoutSubviews方法和實現(xiàn)UITableViewDelegate中的tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath方法:

- (void)viewDidLayoutSubviews{
    [super viewDidLayoutSubviews];
    
    if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        [self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];
    }
    
    if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        [self.tableView setLayoutMargins:UIEdgeInsetsMake(0, 0, 0, 0)];
    }
}

- (void)tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath {
    
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsZero];
    }
    
    if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsZero];
    }
}
