Layout de várias visualizações no NSScrollView usando o Visual AutoLayout
Preciso mostrar várias visualizações alinhadas verticalmente por dentroNSScrollView
, Comecei adicionandoNSTableView
eNSButton
. Alinhei-os verticalmente comNSTableView
em cima eNSButton
no fundo. Eu adicioneiNSTableview
eNSButton
para umNSView
chamadotempView. E defina a exibição do documento deNSScrollView
paratempView.
Mas o problema que estou tendo é que minha tableview não se expande corretamente. Eu vejo os botões, mas o tablview não se expande adequadamente e apenas mostra as últimas entradas que se encaixam na tabela. Como você pode ver na imagem a seguir, ele exibe as últimas 4 linhas de 20 linhas.] Meu código é o seguinte
-(void)setupView {
_scrollView = [[NSScrollView alloc] init];
[_scrollView setHasVerticalScroller:YES];
[_scrollView setHasVerticalRuler:YES];
[_scrollView setBorderType:NSBezelBorder];
[_scrollView setBackgroundColor:[NSColor purpleColor]];
_scrollView.autoresizingMask = NSViewHeightSizable;
_tableView = [[NSTableView alloc] init];
[_tableView setDataSource:self];
[_tableView setHeaderView:nil];
[_tableView addTableColumn:[[NSTableColumn alloc] initWithIdentifier:@"firstColumn"]];
[_tableView setDelegate:self];
[_tableView setColumnAutoresizingStyle:NSTableViewUniformColumnAutoresizingStyle];
[_tableView setBackgroundColor:[NSColor greenColor]];
NSButton* _button = [[NSButton alloc] initWithFrame:NSZeroRect];
NSView* tempView = [[NSView alloc] initWithFrame:NSZeroRect];
[tempView setTranslatesAutoresizingMaskIntoConstraints:NO];
[_scrollView setTranslatesAutoresizingMaskIntoConstraints:NO];
[_button setTranslatesAutoresizingMaskIntoConstraints:NO];
[_tableView setTranslatesAutoresizingMaskIntoConstraints:NO];
[tempView addSubview:_button];
[tempView addSubview:_tableView];
[_scrollView setDocumentView:tempView];
[self addSubview:_scrollView];
NSString *const kViewContainerVertical = @"V:|[tempView]|";
NSString *const kViewContainerHorizontal = @"H:|[tempView]|";
NSDictionary *viewDictionary = NSDictionaryOfVariableBindings(tempView);
NSArray *contraintOneView = [NSLayoutConstraint constraintsWithVisualFormat:kViewContainerVertical
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:viewDictionary];
NSArray *constraintTwoView = [NSLayoutConstraint constraintsWithVisualFormat:kViewContainerHorizontal
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:viewDictionary];
NSString *const kViewVertical = @"V:|[_tableView]-2-[_button]|";
NSString *const kTextViewHorizontal = @"H:|[_tableView(_button)]-0-|";
NSString *const kButtonHorizontal = @"H:|-0-[_button]-0-|";
NSDictionary *dictionary = NSDictionaryOfVariableBindings(_tableView, _button);
NSArray *contraintOne = [NSLayoutConstraint constraintsWithVisualFormat:kViewVertical
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:dictionary];
NSArray *constraintTwo = [NSLayoutConstraint constraintsWithVisualFormat:kTextViewHorizontal
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:dictionary];
NSArray *constraintThree = [NSLayoutConstraint constraintsWithVisualFormat:kButtonHorizontal
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:dictionary];
[tempView addConstraints:contraintOne];
[tempView addConstraints:constraintTwo];
[tempView addConstraints:constraintThree];
[_scrollView.contentView addConstraints:contraintOneView];
[_scrollView.contentView addConstraints:constraintTwoView];
NSString *const kScrollVertical = @"V:|-0-[_scrollView]-0-|";
NSString *const kScrollHorizontal = @"H:|-0-[_scrollView]-0-|";
NSDictionary *scrollDictionary = NSDictionaryOfVariableBindings(_scrollView);
NSArray *contraintOneScroll = [NSLayoutConstraint constraintsWithVisualFormat:kScrollVertical
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:scrollDictionary];
NSArray *constraintTwoScroll = [NSLayoutConstraint constraintsWithVisualFormat:kScrollHorizontal
options:NSLayoutFormatAlignAllLeft
metrics:nil
views:scrollDictionary];
[self addConstraints:contraintOneScroll];
[self addConstraints:constraintTwoScroll];
}
Não estou entendendo o motivo de tal comportamento.
