//去掉UItableview的section的headerview悬浮
CGFloat sectionHeaderH = 10;
if (scrollView.contentOffset.y<=sectionHeaderH && scrollView.contentOffset.y>=0) {
scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
} else if (scrollView.contentOffset.y>=sectionHeaderH) {
scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderH, 0, 0, 0);
}else{
scrollView.contentInset = UIEdgeInsetsZero;
}
//去掉UItableview的section的footerview悬浮
CGFloat sectionFooterH = 10;
if (scrollView.contentOffset.y<=sectionFooterH && scrollView.contentOffset.y>=0) {
scrollView.contentInset = UIEdgeInsetsMake(0, 0, -sectionFooterH, 0);
} else if (scrollView.contentOffset.y>= sectionFooterH) {
scrollView.contentInset = UIEdgeInsetsMake(0, 0, -sectionFooterH, 0);
}else{
scrollView.contentInset = UIEdgeInsetsZero;
}
同时使用或者其他地方涉及到contentInset修改时记得处理
其实不管是头部悬浮还是底部悬浮都是修改 contentInset 它其实还是悬浮只是在界面中看不到了
