1.实现单元格的删除，实现效果如下

Cpp代码

- (void)viewDidLoad
{
[super viewDidLoad];
//设置导航栏
self.editButtonItem.title = @"编辑";
self.navigation.rightBarButtonItem = self.editButtonItem;
[self initTableViewData];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)initTableViewData{
NSBundle *bundle = [NSBundle mainBundle];
NSString *plistPath = [bundle pathForResource:@"user_head" ofType:@"plist"];
dataArr = [[NSMutableArray alloc] initWithContentsOfFile:plistPath];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [dataArr count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"tableCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSUInteger row = [indexPath row];
NSDictionary *rowDict = [dataArr objectAtIndex:row];
cell.textLabel.text = [rowDict objectForKey:@"itemName"];
NSLog(@"cell.label.text = %@",[rowDict objectForKey:@"itemName"]);
NSString *imagePath = [rowDict objectForKey:@"itemImagePath"];
cell.imageView.image = [UIImage imageNamed:imagePath];
NSLog(@"cell.image.image = %@",imagePath);
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
//选中Cell响应事件
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[tableView deselectRowAtIndexPath:indexPath animated:YES];//选中后的反显颜色即刻消失
NSUInteger row = [indexPath row];
NSDictionary *rowDict = [dataArr objectAtIndex:row];
NSString *userName = [rowDict objectForKey:@"itemName"];
NSLog(@"userName=%@",userName);
}
//返回编辑状态的style
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
//UITableViewCellEditingStyleInsert
// return UITableViewCellEditingStyleNone;
return UITableViewCellEditingStyleDelete;
}
//完成编辑的触发事件
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete)
{
[dataArr removeObjectAtIndex: indexPath.row];
// [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
// withRowAnimation:UITableViewRowAnimationFade];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
withRowAnimation:UITableViewRowAnimationFade];
[tableView reloadData];
}
}
//UIViewController生命周期方法，用于响应视图编辑状态变化
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[self.tableView setEditing:editing animated:YES];
if (self.editing) {
self.editButtonItem.title = @"完成";
} else {
self.editButtonItem.title = @"编辑";
}
}
@end

2.移动单元格

Cpp代码

//完成移动的触发事件，不添加该方法不实现移动功能
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath*)sourceIndexPath
toIndexPath:(NSIndexPath *)destinationIndexPath
{
NSDictionary *item = [dataArr objectAtIndex:sourceIndexPath.row];
[dataArr removeObjectAtIndex:sourceIndexPath.row];
[dataArr insertObject:item atIndex:destinationIndexPath.row];
}

3.添加单元格。下面是自定义触发事件，即单击左下角的add按钮

Cpp代码

- (IBAction)addistItem:(UIBarButtonItem *)sender {
AppUtils *appUtils = [AppUtils alloc];
//需要先初始化一个UIAlertView
UIAlertView *alert = [UIAlertView alloc];
[appUtils showInputDialogWithTitle:@"add" message:@"please input new user name:" toAlertView:alert confirmAction:(^{
//得到输入框
UITextField *textField=[alert textFieldAtIndex:0];
// 不要写成NSMutableDictionary *newItem = [NSDictionary dictionary];
NSMutableDictionary *newItem = [NSMutableDictionary dictionary];
[newItem setObject:textField.text forKey:@"itemName"];
[newItem setObject:@"1.jpeg" forKey:@"itemImagePath"];
[dataArr addObject:newItem];
[self.tableView reloadData];
})];
}

4.附上·AppUtils类

Cpp代码

#import "AppUtils.h"
#include "RIButtonItem.h"
#include "UIAlertView+Blocks.h"
@implementation AppUtils
//弹出警告框，并实现警告框按钮的触发事件
- (void)showInputDialogWithTitle:(NSString *)title message:(NSString *)message toAlertView:(UIAlertView*) alert confirmAction:(void(^)(void))action{
RIButtonItem* cancelItem = [RIButtonItem item];
cancelItem.label = @"No";
cancelItem.action = ^
{
//为NO时的处理
UITextField *tf=[alert textFieldAtIndex:0];
NSLog(@"UITextField=%@",tf.text);
};
RIButtonItem* confirmItem = [RIButtonItem item];
confirmItem.label = @"Yes";
// confirmItem.action = action;
alert = [alert initWithTitle:title
message:message
cancelButtonItem:cancelItem
otherButtonItems:confirmItem, nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
confirmItem.action = action;
[alert show];
}
@end
