点击按钮，切换相应的collection界面。 点击按钮时调用如下方法，调用scrollToItemAtIndex:index，偶发无效。 如果将animate 设置为NO则正常。

- (void)topBtnClick:(NSInteger)index{
    __weak typeof (self) weakself = self;
    [UIView animateWithDuration:0.3 animations:^{
        [weakself.pagerView reloadDataNeedResetIndex];
    } completion:^(BOOL finished) {
        [weakself.pagerView scrollToItemAtIndex:index animate:YES];
    }];
}

在调用scrollToItemAtIndex 之前可以调用 [weakself.pagerView scrollToNearlyIndexAtDirection:TYPagerScrollDirectionRight animate:YES];可解决
