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
- (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]; }
//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]; })]; }
- (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
#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
