先看下效果图
直接上代码
#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 = ; i < ; i++) {
NSString *str = [NSString stringWithFormat:@"第%d行",i + ];
[self.array addObject:str];
} button = [UIButton buttonWithType:(UIButtonTypeCustom)];
[button setTitle:@"选择" forState:(UIControlStateNormal)];
[button setTitleColor:[UIColor blackColor] forState:(UIControlStateNormal)];
button.frame = CGRectMake(, , , ); [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 ;
} - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.array.count;
} - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *Identifier = @"myCell";
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 > ) { [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 > ) {
[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;
}
如果要把tableView在非编辑状态下不让点击,设置下这个属性,就OK了.
@property (nonatomic) BOOL allowsSelection NS_AVAILABLE_IOS(3_0); // default is YES. Controls whether rows can be selected when not in editing mode
如果在某些情况下需要全选,可以按照这个思路:
for (int i = ; i < self.array.count; i++) {
NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:];
UITableViewCell *cell = (UITableViewCell *)[self.tableView cellForRowAtIndexPath:path];
cell.selected = YES;
[self.selectorPatnArray addObject:self.array[i]];//添加到选中列表
}
这只是个人想法,欢迎指出不足......
