第一种方式：
-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{ return YES;}- (NSArray*)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewRowAction *detele = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"删除" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) {
self.popView = [[ZYFPopview alloc]initInView:[UIApplication sharedApplication].keyWindow tip:@"删除笔记?" images:(NSMutableArray*)@[] rows:(NSMutableArray*)@[@"删除"] doneBlock:^(NSInteger selectIndex) {
NSFileManager *manager=[NSFileManager defaultManager];
NSString *filepath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"notes.plist"];
if ([manager removeItemAtPath:filepath error:nil]) {
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [path objectAtIndex:0];
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"notes.plist"];
[self.notesDatas removeObjectAtIndex:indexPath.row];//bug
[self.notesDatas writeToFile:plistPath atomically:YES];
if (self.notesDatas.count==0) {
[self.tableView removeFromSuperview];//removeFromSuperview将视图从父视图上移开并且销毁，但是如果其他地方对他还有引用，只是移开了视图但是不会销毁
[self createimgeView];
}else{
[self.tableView reloadData];
}
}
} cancleBlock:^{
}];
[self.popView showPopView];
}];
detele.backgroundColor = [UIColor redColor];
return @[detele];
}
当然这种方式的可以添加多个按钮。
第二种方式：
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewCellEditingStyleDelete;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
if (editingStyle == UITableViewCellEditingStyleDelete) {
FavoriteModel * model = self.dataSource[indexPath.row];
[FavoriteModel MR_deleteAllMatchingPredicate:[NSPredicate predicateWithFormat:@"pid=%@",model.pid]];
[self.dataSource removeObjectAtIndex:indexPath.row];
[self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
}
- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{
return @"删除";
}
