我想为 uitableviewrowaction 按钮设置顶部和底部约束
这是我的代码
- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
}];
deleteAction.backgroundColor = [UIColor redColor];
return @[deleteAction];
}
像这样我添加了删除按钮。在 tableviewCell 中，我添加了一个 UIView 它具有顶部和底部约束。我希望删除按钮与我在 UITableviewCell 中的 View 匹配。
最佳答案
您可以在自定义uitableviewcell类中设置删除按钮框架
像这样
-(void)didTransitionToState:(UITableViewCellStateMask)state
{
[super didTransitionToState:state];
if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask)
{
UIView *deleteButton = [self deleteButtonSubview:self];
if (deleteButton)
{
CGRect frame = deleteButton.frame;
frame.origin.y = 4;
frame.size.height = frame.size.height-8;
/*
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
frame.size.height = 62; //vikram singh 2/1/2015
frame.size.width = 80;
}
else
{
frame.size.height = 52; //vikram singh 2/1/2015
frame.size.width = 80;
}
*/
deleteButton.frame = frame;
}
}
}
- (UIView *)deleteButtonSubview:(UIView *)view
{
if ([NSStringFromClass([view class]) rangeOfString:@"Delete"].location != NSNotFound) {
return view;
}
for (UIView *subview in view.subviews) {
UIView *deleteButton = [self deleteButtonSubview:subview];
[deleteButton setBackgroundColor:[UIColor whiteColor]];
if (deleteButton) {
return deleteButton;
}
}
return nil;
}
使用didTransitionToState方法:)
