问题 I have a tableview with a label and an image. in some cells, there is no image as i used imageView.removeFromSuperview() to remove it from the cell. When there is an image in the cell, the row height is 445 and "Custom" is checked off. how can i set the row height dynamically according to how long the label is instead of how long/big the imageview is after i remove the imageview? 回答1: If you want dynamic row height, you can define your constraints (making sure they're unambiguous), set the

问题 I'm trying to add a UITableView to an existing UIViewController programmatically. My run.h file has this: @interface runTests : UIViewController <UINavigationControllerDelegate,UITextFieldDelegate,UIAlertViewDelegate,UITableViewDelegate,UITableViewDataSource> {NSTimer *Timer;} @property (strong, nonatomic) UITableView *tableView; My app runs through a speed test and at the end of the test I'm trying to add a TableView to the View. At the moment I have this: -(void)addSpeedTable { self

问题 In Unit Test, I have a simple table view with a bunch of basic cells (cells with just a label). I would like to access the cell using cellForRow(at:) , so I can test thing like selecting and deselecting the row programmatically, but this cellForRow query always returns nil . There is some discussion online that I should be using the data source's tableView(_, cellForRowAt:) instead. This is not my intention. I only want to test the cell's visibility, test selecting and deselecting them. To

问题 I know similar issues have been posted before but I can't find a solution for me within them so please bear with me... I have a tableview with a custom table cell in xcode. The cell is currently nothing more than a label: SiteFileCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; cell.fileNameLabel.text = [self.listDir.filesInfo objectAtIndex:indexPath.row]; This works great. I am essentially doing a directory drill down structure. When I select

问题 I have a table with 3 rows each with check button.What I am doing is when I select all the three buttons I want to click my cancel button which is on view not table on same controller to reload all 3 rows the call goes to custom cell class where uncheck is set to true and rows are reloaded.For the first attempt it works fine I can see correct index to be reloaded.On the second time again when I select all 3 check buttons and click cancel again I can see correct index to be reloaded but the

问题 I have a table view with a custom Cell which gets it contents from an array, this all builds fine. I want to add to this content a Collection View of thumb nail images of varying number to each of the custom Table View Cells. I have added the Collection to the Custom Cell in the Story Board. I have linked the Collection to the Custom Cell.m (not sure it should go there). I have created a Collection Custom Cell and linked the image in. It is from here I am not sure, should the methods for

问题 The app in question has an ability for users to mark items as favourite. When the user has no favourites saved, I'd like to notify them of the fact (mostly I hate the idea of a blank tableView). My numberOfRowsInSection is zero when there are no items the user has marked as favourite. I'd like to set cell.textLabel.text = @"You have no favourites" but when there are no items for the table cellForRowAtIndexPath is not called. I could test numberOfRowsInSection to give a result when it

问题 In the classic pattern below the returned cell from dequeueReusableCellWithIdentifier is always non nil . Why? Shouldn't we have to allocated some cell first then we can have some to be reused? I am using a customize cell and it was created in the storyboard. (However, if I had used the default UITableViewCell ,the phenomena is same - the returned cell is still always non-nil ). Enviroment: Xcode 4.3.3 iOs 5.1 AlbumListCell *cell = [tableView dequeueReusableCellWithIdentifier:@"AlbumCell"]; /
