制作可以滑动操作的TableViewCell

2015-08-13

之前发过一篇文章TableView编辑模式
里面有一个小节说明了iOS7之前如何制作可以滑动操作的TableViewCell，制作过程极其蛋疼。
iOS8之后，苹果终于提供API给开发者了，废话少说，上代码

##iOS8新增的API

typedef NS_ENUM(NSInteger, UITableViewRowActionStyle) {
    UITableViewRowActionStyleDefault = 0,
    UITableViewRowActionStyleDestructive = UITableViewRowActionStyleDefault,
    UITableViewRowActionStyleNormal
} NS_ENUM_AVAILABLE_IOS(8_0);

NS_CLASS_AVAILABLE_IOS(8_0) @interface UITableViewRowAction : NSObject <NSCopying>

+ (instancetype)rowActionWithStyle:(UITableViewRowActionStyle)style title:(NSString *)title handler:(void (^)(UITableViewRowAction *action, NSIndexPath *indexPath))handler;

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath NS_AVAILABLE_IOS(8_0);

##实现代码

/**
 *  必须重写，否则只有进入编辑模式才能滑动cell
 *
 */
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
    
    // 删除
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        
        [self.arrayValue removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }
}


/**
 *  cell添加滑动显示按钮
 *
 */
- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath{
    
    //设置删除按钮
    UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"删除"handler:^(UITableViewRowAction *action,NSIndexPath *indexPath) {
        
        [self.arrayValue removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
        
    }];
    
    //设置收藏按钮
    UITableViewRowAction *collectRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"收藏"handler:^(UITableViewRowAction *action,NSIndexPath *indexPath) {
        
        
        collectRowAction.backgroundColor = [UIColor greenColor];
        
        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"收藏" message:@"收藏成功" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alertView show];
        
        
    }];
    
    //设置置顶按钮
    UITableViewRowAction *topRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"置顶" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
        
        
        [self.arrayValue exchangeObjectAtIndex:indexPath.row withObjectAtIndex:0];
        
        NSIndexPath *firstIndexPath = [NSIndexPath indexPathForRow:0 inSection:indexPath.section];
        [tableView moveRowAtIndexPath:indexPath toIndexPath:firstIndexPath];
        
    }];
    
    topRowAction.backgroundColor = [UIColor blueColor];
    
    // collectRowAction添加毛玻璃特效
    collectRowAction.backgroundEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
    collectRowAction.backgroundColor = [UIColor grayColor];
    
    return  @[deleteRowAction,collectRowAction,topRowAction];
}
