searchBar 隐藏

searchBar 隐藏

CGRect newBounds = self.tableView.bounds;

newBounds.origin.y = newBounds.origin.y + _headerSearchBar.bounds.size.height;

self.tableView.bounds = newBounds;

但是这样隐藏后 当cell个数较少时会出现,push到下一界面再pop回到当前界面searchBar 会重新出现,

动态设置TableFooterView, 使cell的总高度加上TableFooterView的高度大于tableView的高度,就可以避免这一现象.

-(void)tableViewFooterViewHight{

CGRect rect = self.tableView.tableFooterView.frame;

UIView * view = self.tableView.tableFooterView;

self.tableView.tableFooterView = nil;

CGFloat hight = 0;

hight = 62+50;

ABAuthorizationStatus authStatus =

ABAddressBookGetAuthorizationStatus();

if(authStatus != kABAuthorizationStatusAuthorized){

hight +=40;

}else{

hight += 0.0f;

}

hight += 30.f;

hight += ( _data.count + 1 )*65.f;

hight = CGRectGetHeight(self.tableView.frame) - hight;

rect.size.height = hight;

view.frame = rect;

self.tableView.tableFooterView = view;

}
