uitableview

问题 I am populating a UITableView with images selected by the user. I'd like to the have thumbnails in the table cells all be the same size without affecting the aspect ratio so as not to stretch/skew the images, which sounds to me like ScaleAspectFill , however none of the UIViewContentMode selections seem to have an effect. There me conflicting methods, notable heightForRowAtIndexPath , but removing this makes my cells too small. The following are my didSelectRowAtIndexPath and

问题 I'm trying to populate a UITableview with an array of cells. I usually do this from the viewDidLoad method but this time I want to populate the array based on location. Below is the first line of my interface: @interface RootViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource, CLLocationManagerDelegate> { In the implementation file the viewDidLoad method looks like this: - (void)viewDidLoad { // for location self.locationManager = [[CLLocationManager alloc] init

问题 I want to display a UITableView inside a UIViewController . This View Controller contains a UISegmentedControl with two screens ( FirstViewController and SecondViewController ). The first View Controller is the one that contains the UIViewTable (please don't mind the second).

问题 I'm having a weird issue with a particular UITableView in my iPhone devel experience here. If you look at the following screenshot: alt text http://dl-client.getdropbox.com/u/57676/brokencell.png you'll notice a strike through going through the middle of the 'Jane Aba' cell.

As requested, here's my -tableView:cellForRowIndexPath: method: * EDIT * I've located

问题 I have 3 uitableviews in a single uiscrollview. Each uitableview is full length and not scrollable so that the outer uiscrollview scrolls them together. This works fine except the uitableviews believe all cells are visible so that all are created up front. Even this is acceptable except each call has an image view (a thumbnail) that is loaded asynchronously from a url. I am trying to figure out how to limit the image loading to only visible cells but still allow the user to scroll the outer

问题 In my app, I changed the background color of every view to dark. But when I delete a row from tableView, row background changed to white.
