这样设置就可以了：

Searched for a while and got this issue fixed by

scrollview.panGestureRecognizer.delaysTouchesBegan = YES;

—————————————————————
另外：

I found that in iOS 8, the UIScrollView‘s underlying UIPanGestureRecognizer is not respecting the UIScrollView‘s delaysContentTouches property. I consider this an iOS 8 bug. Here‘s my workaround:

theScrollView.panGestureRecognizer.delaysTouchesBegan = theScrollView.delaysContentTouches

And there‘s also another workaround (but I tried without lucky, cause UIControl instances not works then, let me know if u‘ve any idea about it, thx):

if (floor((NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1)) {
    UITapGestureRecognizer * nothingTap = [[UITapGestureRecognizer alloc] init];
    [nothingTap setDelaysTouchesBegan:YES];
    [scrollView addGestureRecognizer:nothingTap];
}

再另外，还可以写一个继承UIScrollView的子类：
