搜索建议searchTextDidChange的回调问题

[liyanjun]

当自定义搜索建议的cell且searchTextDidChange中执行搜索时，搜索结果列表没有刷新。查看源代码为

- (void)setSearchSuggestions:(NSArray<NSString *> *)searchSuggestions
{
    if ([self.dataSource respondsToSelector:@selector(searchSuggestionView:cellForRowAtIndexPath:)]) {
        // set searchSuggestion is nil when cell of suggestion view is custom.
        _searchSuggestions = nil;
        return;
    }

    _searchSuggestions = [searchSuggestions copy];
    self.searchSuggestionVC.searchSuggestions = [searchSuggestions copy];

    self.baseSearchTableView.hidden = !self.searchSuggestionHidden && [self.searchSuggestionVC.tableView numberOfRowsInSection:0];
    self.searchSuggestionVC.view.hidden = self.searchSuggestionHidden || ![self.searchSuggestionVC.tableView numberOfRowsInSection:0];
}

通过源代码可知道，当有自定义cell时，就直接return了，也就不会执行的searchSuggestionVC.tablevew reload。所以我修改了一下，修改为当有自定义cell时，也会reload一下；

- (void)setSearchSuggestions:(NSArray<NSString *> *)searchSuggestions
{
    if ([self.dataSource respondsToSelector:@selector(searchSuggestionView:cellForRowAtIndexPath:)]) {
        // set searchSuggestion is nil when cell of suggestion view is custom.
        [self.searchSuggestionVC.tableView reloadData];
        _searchSuggestions = nil;
        return;
    }

    _searchSuggestions = [searchSuggestions copy];
    self.searchSuggestionVC.searchSuggestions = [searchSuggestions copy];

    self.baseSearchTableView.hidden = !self.searchSuggestionHidden && [self.searchSuggestionVC.tableView numberOfRowsInSection:0];
    self.searchSuggestionVC.view.hidden = self.searchSuggestionHidden || ![self.searchSuggestionVC.tableView numberOfRowsInSection:0];
}
