1.实现单元格的删除，实现效果如下

- (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

//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

- (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

#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
