实现思路
=======
重写 UITableView 的代理方法，实现“置顶”和“删除”功能。（由于重写代理方法，SDK 父类中的“删除”功能失效）
示例代码
- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath
{
RCConversationModel *model = self.conversationListDataSource[indexPath.row];
NSString *topStr = @"置顶";
if (model.isTop == YES) {
topStr = @"取消置顶";
}
__weak typeof(self) __weakself = self;
UITableViewRowAction *action0 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:topStr handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
BOOL isSuccess = [[RCIMClient sharedRCIMClient] setConversationToTop:model.conversationType targetId:model.targetId isTop:!model.isTop];
[__weakself refreshUI:isSuccess];
}];
action0.backgroundColor = [UIColor orangeColor];
UITableViewRowAction *action1 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"删除" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
BOOL isSuccess = [[RCIMClient sharedRCIMClient] removeConversation:model.conversationType targetId:model.targetId];
[__weakself refreshUI:isSuccess];
}];
return @[action1, action0];
}
- (void)refreshUI:(BOOL)isSuccess {
__weak typeof(self) __weakself = self;
if (isSuccess) {
[__weakself refreshConversationTableViewIfNeeded];
} else {
NSLog(@"操作失败");
}
}
效果图：
