复制代码
NSArray *leftBarButtons = [NSArray arrayWithObjects:self.addButton,self.deleteBarButtonItem, nil];
self.navigationItem.leftBarButtonItems = leftBarButtons;//设置导航栏左边按钮为添加和删除按钮
③在@interface中声明一个变量
复制代码
UITableViewCellEditingStyle selectEditingStyle;
④两个按钮的点击事件
复制代码
// 更新导航栏按钮
-(void) updateBarButtons
{
if (self.tableView.editing==YES) {
self.navigationItem.rightBarButtonItem = self.doneBarButtonItem;
}
}
// 点击添加按钮
- (IBAction)addButtonClicked:(id)sender {
selectEditingStyle = UITableViewCellEditingStyleInsert;
[self.tableView setEditing:YES animated:YES];
[self updateBarButtons];
}
// 点击删除按钮
- (IBAction)deleteButtonClicked:(id)sender {
selectEditingStyle = UITableViewCellEditingStyleDelete;
[self.tableView setEditing:YES animated:YES];
[self updateBarButtons];
}
⑤实现相应的代理方法
复制代码
// 是否可编辑
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
// 编辑模式
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return selectEditingStyle;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
