//调用一个方法,让cell进入编辑状态进入编辑状态

- (void)changeSegmentedC:(UISegmentedControl *)sender{

[self.tableView setEditing:sender.selectedSegmentIndex animated:YES];

return;

}

2)设置每个cell进入什么样的编辑状态

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{

if (indexPath.row == self.dataArr.count - 1) {

return UITableViewCellEditingStyleInsert;

}

return UITableViewCellEditingStyleDelete;

}

3)设置哪些cell可以被编辑

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{

if (indexPath.row == 0) {

return NO;

}

return YES;

}

4)自定义删除按钮的title

NSString *str = [NSString stringWithFormat:@"册除%@",self.dataArr[indexPath.row]];

return str;

}

5)松手后取消选中

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

[tableView deselectRowAtIndexPath:indexPath animated:YES];

}

6)添加和删除cell

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{

switch (editingStyle) {

case UITableViewCellEditingStyleDelete:

[self.dataArr removeObjectAtIndex:indexPath.row];

[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

break;

case UITableViewCellEditingStyleInsert:{

[self.dataArr addObject:@"学习"];

NSIndexPath *indexP = [NSIndexPath indexPathForRow:self.dataArr.count - 1 inSection:0];

[tableView insertRowsAtIndexPaths:@[indexP] withRowAnimation:UITableViewRowAnimationLeft];

}

default:

break;

}
