我在定制一个UITableView。我想隐藏在最后一个单元格上的分离线…我能这样做吗?
我知道我可以用tableView。separatorStyle = UITableViewCellStyle。没有,但是这会影响tableView的所有单元格。我希望它只影响最后一个单元格。

所有答案的代码将使单元格填充为零,而不是默认值。我在iOS 11 iPad Pro 12中看到了这个问题。”
但我有一个解决方案(“肮脏的hack”),那就是使一个空的部分,将使分隔线隐藏。
下面是我使用的代码:
typedef enum PXSettingsTableSections {
PXSettingSectionInvite = 0,
PXSettingSectionAccount,
PXSettingSectionPrivacy,
PXSettingSectionCreation,
PXSettingSectionTest,
PXSettingSectionAboutHide, // invisble section just to hide separator Line
PXSettingSectionFooterHide, // invisble section just to hide separator Line
PXSettingSectionNumItems,
} PXSettingsTableSectionsType;
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return PXSettingSectionNumItems;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
switch (section) {
case PXSettingSectionInvite: return 1;
case PXSettingSectionAccount:return (isSocialLogin) ? 1 : 2;
case PXSettingSectionPrivacy: return 1;
case PXSettingSectionCreation: return 2;
case PXSettingSectionTest: return 3;
case PXSettingSectionAboutHide: return 3;
default: return 0;
}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
switch(section)
{
case PXSettingSectionInvite: return nil;
case PXSettingSectionAccount: return @"Account";
case PXSettingSectionPrivacy: return @"Privacy";
case PXSettingSectionCreation: return @"Someting";
case PXSettingSectionTest: return @"Test";
case PXSettingSectionAboutHide: return @" ";
case PXSettingSectionFooterHide: return @" ";
}
return nil;
}
- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
if (section == PXSettingSectionFooterHide || section == PXSettingSectionAboutHide) {
// [UIColor clearColor] will not work
[header.contentView setBackgroundColor:[UIColor whiteColor]];
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
// You can control here the size of one specific section
if(section == PXSettingSectionAboutHide){
return 0.0000001; //make it real small
}
return 45.0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
switch(indexPath.section)
{
case PXSettingSectionInvite:
return self.inviteCell;
case PXSettingSectionAccount:
if (isSocialLogin) {
return self.myWalletCell;
}
switch(indexPath.row)
{
case 0: return self.changePasswordCell;
case 1: return self.myWalletCell;
}
case PXSettingSectionPrivacy:
switch(indexPath.row)

case PXSettingSectionAboutHide:{

case 0: return self.clearCacheCell;
case 1: return self.feedbackCell;
case 2: return self.logoutCell;
}
}
}
return self.emptyCell;
}

设置separatorInset。right = . greatestfinitemagnitude。
我的要求是将分隔符隐藏在第4和第5单元格之间。我通过
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row == 3)
{
cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0);
}
}
在你的UITableViewCell子类中,覆盖layoutSubviews并隐藏_UITableViewCellSeparatorView。适用于iOS 10。
override func layoutSubviews() {
super.layoutSubviews()
subviews.forEach { (view) in
if view.dynamicType.description() == "_UITableViewCellSeparatorView" {
view.hidden = true
}
}
}
如果你不想自己画分隔符,使用这个:
// Hide the cell separator by moving it to the far right
cell.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);
这个API只能从ios7开始使用。
