tableview 多选操作
效果图：
代码：
#import "MyController.h"
@interface MyController ()
{
UIButton *button;
}
@property(nonatomic,strong)NSMutableArray *array;//数据源
@property (nonatomic,strong)NSMutableArray *selectorPatnArray;//存放选中数据
@end
@implementation MyController
- (void)viewDidLoad {
[super viewDidLoad];
//添加数据源
for (int i = 0; i < 10; i++) {
NSString *str = [NSString stringWithFormat:@"第%d行",i + 1];
[self.array addObject:str];
}
button = [UIButton buttonWithType:(UIButtonTypeCustom)];
[button setTitle:@"选择" forState:(UIControlStateNormal)];
[button setTitleColor:[UIColor blackColor] forState:(UIControlStateNormal)];
button.frame = CGRectMake(0, 0, 50, 20);
[button addTarget:self action:@selector(selectMore:) forControlEvents:(UIControlEventTouchUpInside)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:button];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.array.count;
}

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:Identifier];
if (!cell) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:Identifier];
}
cell.textLabel.text = self.array[indexPath.row];
cell的selectionStyle不要设置为UITableViewSelectionStyleNone
return cell;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewCellEditingStyleDelete | UITableViewCellEditingStyleInsert;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//选中数据
[self.selectorPatnArray addObject:self.array[indexPath.row]];
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath{
//从选中中取消
if (self.selectorPatnArray.count > 0) {
[self.selectorPatnArray removeObject:self.array[indexPath.row]];
}
}
#pragma mark - 点击事件
- (void)selectMore:(UIBarButtonItem *)action{
if ([button.titleLabel.text isEqualToString:@"选择"]) {
//移除之前选中的内容
if (self.selectorPatnArray.count > 0) {
[self.selectorPatnArray removeAllObjects];
}
[button setTitle:@"确认" forState:(UIControlStateNormal)];
//进入编辑状态
[self.tableView setEditing:YES animated:YES];
}else{
[button setTitle:@"选择" forState:(UIControlStateNormal)];
//对选中内容进行操作
NSLog(@"选中个数是 : %lu 内容为 : %@",(unsigned long)self.selectorPatnArray.count,self.selectorPatnArray);
//取消编辑状态
[self.tableView setEditing:NO animated:YES];
}
}
#pragma mark -懒加载
-(NSMutableArray *)array{
if (!_array) {
_array = [NSMutableArray array];
}
return _array;
}
- (NSMutableArray *)selectorPatnArray{
if (!_selectorPatnArray) {
_selectorPatnArray = [NSMutableArray array];
}
return _selectorPatnArray;
}
全选：
for (int i = 0; i < self.array.count; i++) {
NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:0];
[self.tableView selectRowAtIndexPath:path animated:YES scrollPosition:UITableViewScrollPositionTop];
[self.selectorPatnArray addObject:self.array[i]];//添加到选中列表
}
