1.UITableView补充
1⃣️:-(void)p_data
@property (nonatomic,retain)NSMutableArray *dataArray;
@property (nonatomic,assign)UITableViewCellEditingStyle editStyle;
- (void)p_data{
NSMutableArray *arr1 = @[@"范冰冰",@"宋慧乔",@"周迅"].mutableCopy;
NSMutableArray *arr2 = @[@"bangbangbang",@"boomshakalaka",@"comeonboys",@"comeongirls"].mutableCopy;
self.dataArray = [NSMutableArray array];
[self.dataArray addObject:arr1];
[self.dataArray addObject:arr2];
}
2⃣️:number
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return self.dataArray.count;
}
3⃣️:row
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [self.dataArray[section] count];
}
cell.textLabel.text = self.dataArray[indexPath.section][indexPath.row];
2.UITableView修改
1⃣️:让tableView处于编辑状态
- (void)p_navigation{
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"SET" style:UIBarButtonItemStyleDone target:self action:@selector(rightAction:)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"ADD" style:UIBarButtonItemStyleDone target:self action:@selector(leftAction:)];
}
- (void)leftAction:(UIBarButtonItem *)sender{
self.editStyle = UITableViewCellEditingStyleInsert;
[self.rv.tableView setEditing:!self.rv.tableView.editing animated:YES];
}
- (void)rightAction:(UIBarButtonItem *)sender{
self.editStyle = UITableViewCellEditingStyleDelete;
[self.rv.tableView setEditing:!self.rv.tableView.editing animated:YES];
}
2⃣️:指定可以编辑的行
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
return YES;
}
3⃣️:指定tableView编辑的样式
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return self.editStyle;
}
4⃣️:完成编辑
①:修改数据流
1.[self.dataArray[indexPath.section] removeObjectAtIndex:indexPath.row];
2.[self.dataArray[indexPath.section] insertObject:@"New Peole" atIndex:indexPath.row + 1];
②:修改 UI
1[self.rv.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationRight];
2.NSIndexPath *newIndex = [NSIndexPath indexPathForRow:indexPath.row+1 inSection:indexPath.section];
[self.rv.tableView insertRowsAtIndexPaths:@[newIndex] withRowAnimation:UITableViewRowAnimationAutomatic];
③:完整代码:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
if (self.editStyle == UITableViewCellEditingStyleDelete) {
// 1.修改数据源
[self.dataArray[indexPath.section] removeObjectAtIndex:indexPath.row];
// 2.修改UI
[self.rv.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationRight];
}else if (self.editStyle == UITableViewCellEditingStyleInsert){
// 添加
[self.dataArray[indexPath.section] insertObject:@"New Peole" atIndex:indexPath.row + 1];
NSIndexPath *newIndex = [NSIndexPath indexPathForRow:indexPath.row+1 inSection:indexPath.section];
[self.rv.tableView insertRowsAtIndexPaths:@[newIndex] withRowAnimation:UITableViewRowAnimationAutomatic];}
3.UItableView移动
1⃣️:让tableView处于编辑状态
同修改
2⃣️:制定可以移动的行
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath{
return YES;
}
3⃣️:完成移动
①:修改数据源
// 拿出数据
NSString *temp = self.dataArray[sourceIndexPath.section][sourceIndexPath.row];
// 从数组中删掉
[self.dataArray[sourceIndexPath.section] removeObjectAtIndex:sourceIndexPath.row];
// 插入到指定的位置
[self.dataArray[destinationIndexPath.section] insertObject:temp atIndex:destinationIndexPath.row];
②:修改UI
// 修改UI move方法
[self.rv.tableView moveRowAtIndexPath:sourceIndexPath toIndexPath:destinationIndexPath];
③:完整代码:
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{
// 拿出数据
NSString *temp = self.dataArray[sourceIndexPath.section][sourceIndexPath.row];
// 从数组中删掉
[self.dataArray[sourceIndexPath.section] removeObjectAtIndex:sourceIndexPath.row];
// 插入到指定的位置
[self.dataArray[destinationIndexPath.section] insertObject:temp atIndex:destinationIndexPath.row];
// 修改UI move方法
[self.rv.tableView moveRowAtIndexPath:sourceIndexPath toIndexPath:destinationIndexPath];
}
④:不建议限制跨区域
- (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath{
if (sourceIndexPath.section == proposedDestinationIndexPath.section) {
return proposedDestinationIndexPath;
}else {
return sourceIndexPath;
}
}
4.UITableViewController
1⃣️: 先注册
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"cell"];
2⃣️:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];
cell.textLabel.text = @"123";
return cell;
}
