近期很多人反馈iOS10中, textField在输入中文多的情况下,文字会下沉,找了多篇帖子无果,后跟同事找到了解决方案, 亲测有效;

重写layoutSubviews方法, 改变子视图中scrollview的偏移量

- (void)layoutSubviews {
    [super layoutSubviews];
    for (UIScrollView *view in self.subviews) {
        if ([view isKindOfClass:[UIScrollView class]]) {
            CGPoint offset = view.contentOffset;
            if (offset.y != 0) {
                offset.y = 0;
                view.contentOffset = offset;
            }
            break;
        }
        }
}
