我正在尝试完成与此类似的事情：Move a view when scrolling in UITableView但我想在后台移动其中一个视图（并非所有视图）。这是我到目前为止所做的（我使用Masonry作为autoLayout）：
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
//There is an array of views, which I want to move when scrolling
for (UIView *view in self.movedViews) {
CGFloat offset = scrollView.contentOffset.y;
//Here I get the default Y origin of the view, so I can move them equally
originY = view.frame.origin.y;
CGFloat diff = (scrollView.contentInset.top)-originY;
[view mas_updateConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(view.superview.mas_top).with.offset((-offset)-diff);
}];
}
}
问题是我无法在view.frame.origin.y之后使用mas_updateConstraints进行更改$("#body").val("testing123");
var i = 0;
while (i <= 5) {
var value = 20;
function result(a) {
var x = document.getElementsByClassName(a);
return x[0].innerHTML;
}
y = result('val');
setTimeout(function() {
document.getElementById('val').value =value;
setTimeout(function() {
document.getElementById('play').click();
setTimeout(function() {
y = result('val');
if(y == "LOSE") {
bet = value*2;
document.getElementById('val').value =value;
i++;
}
else if(y == "WIN") {
value = 20;
document.getElementById('val').value =value;
i = 5;
}
else {
document.getElementById('val').value ='ERROR';
value = 0;
i = 5;
}
}, 2000);
}, 2000);
}, 7000);
}
。此外，我想让视图在向上滚动时移动。我愿意接受任何不同的解决方案。谢谢你们！
