IOS UITableViewCell transparency and cell text Center

1. When UITableViewCell is created in UITableViewCellStyleValue1 mode, the transparency of UITableView is directly set as follows, but it is difficult to center the text. 2. When the UITableViewCell mode is UITableViewCellStyleDefault, the cell is used directly for text center. textAlignment = UITextAlignmentCenter; the pull is done, but only the transparency of UITableView is set. The background transparency is difficult to implement. Specific implementation code: cell. opaque = NO; cell. textLabel. backgroundColor = [UIColor clearColor]; [cell setBackgroundColor: [UIColor colorWithRed: 1 green: 1 blue: 1 alpha: 0.2]; set the transparency of UITableView to complete the setting.
