iOS开发学习之#提醒处理#(1)响应提醒视图

栏目:综合技术时间:2014-12-13 08:33:17

在这里我用到了视图库里的Navigation Controller导航控制器。

提示操作主要用到了UIAlertviewDelegate协议中的alertView:clickButtonAtIndex:方法实现,其语法情势以下:

- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex;

(UIAlertView *)alertView用来指定正告视图中包括的按钮,(NSInteger)buttonIndex用来指定点击的按钮的索引

核心代码以下:

TableViewController.h

#import <UIKit/UIKit.h> @interface TableViewController : UITableViewController<UITableViewDataSource,UITabBarDelegate,UIAlertViewDelegate>{ NSMutableArray *a; } - (IBAction)aa:(id)sender; - (IBAction)bb:(id)sender; @end

TableViewController.m部份代码片断

- (IBAction)aa:(id)sender { UIAlertView *a = [[UIAlertView alloc]initWithTitle:@"编辑" message:@"请选择项目" delegate:self cancelButtonTitle:@"Canel" otherButtonTitles:@"Add",@"Delete", nil]; [a show]; } - (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ NSString *b = [alertView buttonTitleAtIndex:buttonIndex]; if ([b isEqualToString:@"Delete"]) { [self setEditing:YES]; } if ([b isEqualToString:@"Add"]) { UIAlertView *a1 = [[UIAlertView alloc]initWithTitle:@"添加" message:@"肯定要添加联系人吗" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [a1 show]; } } - (IBAction)bb:(id)sender { [self setEditing:NO]; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{ if (editingStyle == UITableViewCellEditingStyleDelete) { [a removeObjectAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic]; } }
