One of my cells contains a single UITextView and I need it to contract and expand based on user input - tap to shrink/expand the text. I'm doing this by adding a runtime constraint to the text view and changing the constant on the constraint in response to user events: -( void ) collapse :( BOOL ) collapse ; { _collapsed = collapse ; if ( collapse ) [ _collapsedtextHeightConstraint setConstant : kCollapsedHeight ]; // 70

The apple docs regarding the forIndexPath function states, "This method uses the index path to perform additional configuration based on the cell’s position in the table view." I'm not sure how to interpret that though? 回答1: The most important difference is that the forIndexPath: version asserts (crashes) if you didn't register a class or nib for the identifier. The older (non- forIndexPath: ) version returns nil in

I'm having trouble understanding how the cell's size is updated from the contents of what's inside the cell's contentView. Here's the setup I've tried: Custom UICollectionViewCell with a UITextView in its contentView. Scrolling for the UITextView is disabled. The contentView's horizontal constraint is: "H:|[_textView(320)]", i.e. the UITextView is pinned to the left of the cell with an explicit

Worksheet A has a macro that calculates if the data is above a value then calls an email module to email selected users. When the data is manually input on Worksheet A the Macro works, however when data is pulled from Worksheet B it doesn't fire. I'm not sure what I need to change in my VBA code. Private Sub Worksheet_Change(ByVal Target As Range) Call MailAlert(Target, "B5:M5", 4) Call MailAlert(Target, "B8:M8", 7) Call MailAlert(Target, "B11:M11", 6) Call MailAlert(Target

I know which cells need the class applied at generation time of the data being sent down to jqgrid. What I would like is to be able to indicate a class within the jqgrid rows structure for each specific cell: 1.00 15.00 9.00 … 1.00 2.00 1.15 … … I know I can do this formatting after the data is sent down, but I would like to see the grid drawn with the formatting in place rather than after the fact. I've achieved something

I can make it work with one, here is the code: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [contentOne count]; // sets row count to number of items in array } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [self.tableView

My collection view and table view data source methods now contain IndexPath instead of NSIndexPath in their method signature. But still inside the method definition it is type casting IndexPath to NSIndexPath. i.e. func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell : NNAmenitiesOrFurnishingCollectionViewCell = self.amenitiesOrFurnishingCollectionView.dequeueReusableCell(withReuseIdentifier:

I want to update each table view cell individually to reflect changes in the backing array. By changes I mean not append/remove operations but update of the properties of the objects of the array. I hope I was able to explain what I want to achieve. Thanks 回答1: To use KVO, declare the model object with dynamic properties: class Foo: NSObject { @objc dynamic var bar: String // in Swift 3, `@objc` is not necessary; in Swift 4 we must make this explicit init(bar: String) {

The property CurrentCell can be used to set the current cell. You want something like this: private void dataGridView_SelectionChanged(object sender, EventArgs e) { DataGridViewCell currentCell = dataGridView.CurrentCell; if (currentCell != null) { int nextRow = currentCell.RowIndex; int nextCol = currentCell.ColumnIndex + 1; if (nextCol == dataGridView.ColumnCount) {
