写个UITableViewCell的分类重写这个方法

- (void)didMoveToSuperview {

    [super didMoveToSuperview];

    // 全局替换右侧箭头

    if (self.accessoryType == UITableViewCellAccessoryDisclosureIndicator) {

        UIImageView *i = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"btn_enter"]];

        self.accessoryView = i;

    }

}

#pragma mark - UITableViewDelegate

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

    // 不用系统自带的箭头

    if (cell.accessoryType == UITableViewCellAccessoryDisclosureIndicator) {

        UIImage *arrowImage = [UIImage imageNamed:@"btn_enter"];

        UIImageView *arrowImageView = [[UIImageView alloc] initWithImage:arrowImage];

        cell.accessoryView = arrowImageView;

    }

}
