UITableView怎么在非Editing状态下多选

UITableView单选多选使我们经常使用的，使用系统的多选打开UITableView的Editing，然后使用系统的那个蓝色勾选更是用的普遍。那么不打开编辑状态，怎么实现多选呢？

其实只需要一个属性，就是allowsMultipleSelection，核心代码如下：

self.tableView.allowsMultipleSelection = YES;

注意看UITableView的以下属性:

@property (nonatomic) BOOL allowsSelection NS_AVAILABLE_IOS(3_0);  // default is YES. Controls whether rows can be selected when not in editing mode
@property (nonatomic) BOOL allowsSelectionDuringEditing;                                 // default is NO. Controls whether rows can be selected when in editing mode
@property (nonatomic) BOOL allowsMultipleSelection NS_AVAILABLE_IOS(5_0);                // default is NO. Controls whether multiple rows can be selected simultaneously
@property (nonatomic) BOOL allowsMultipleSelectionDuringEditing NS_AVAILABLE_IOS(5_0);   // default is NO. Controls whether multiple rows can be selected simultaneously in editing mode
