1.發(fā)現(xiàn)問(wèn)題

最近復(fù)查老代碼,發(fā)現(xiàn)原來(lái)在CellView中自定義左滑按鈕的方法失效了,

- (void)didTransitionToState:(UITableViewCellStateMask)state;
- (void)willTransitionToState:(UITableViewCellStateMask)state;
- (void)layoutSubviews;

原在這三個(gè)方法中獲取UITableViewCellDeleteConfirmationView找不到了,翻看了下文檔,原來(lái)是ios系統(tǒng)更新中改變了view的層級(jí)結(jié)構(gòu).

2.解決問(wèn)題

于是乎,我找到在tableview的代理方法

-(void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath

中操作是個(gè)很好的地方,上個(gè)簡(jiǎn)單的示例代碼

- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
    for (UIView *subview in tableView.subviews) {
        if ([NSStringFromClass([subview class]) isEqualToString:@"UISwipeActionPullView"]) {
            if ([NSStringFromClass([subview.subviews[0] class]) isEqualToString:@"UISwipeActionStandardButton"]) {   
      
                subview.subviews[0].backgroundColor = [UIColor colorWithHexString:@"#FF556A"];
                UIImageView * imgV = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"wtImg"]];
                imgV.X = 25;imgV.Y = 18;
                [subview.subviews[0] addSubview:imgV];
            }
        }
    }
}

搞定. 歡迎大家指正
