ios8

问题 I'm building a iOS 8 custom keyboard and I'd like the change the layout of the keyboard based on the UIKeyboardType, however, reading the keyboard type in UIInputViewController is always 0. Any suggestions? Thanks in advance! - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"TextInputMode: %ld", self.textDocumentProxy.keyboardType); } 回答1: Get the keyboardType in InputView Delegate Methods Instead of ViewDidLoad . Because you can't get the keyboardType until The keyboard is fully presented

问题 I want to save a mp4 video in my folder but when I open again the app, this file is nil. But when I save the file, I can open it, so it seems that it disappears from the folder. Save: NSData *videoData = [NSData dataWithContentsOfURL:exportUrl]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/%@",videoName]; self.path

问题 I have the following layout So it's basically a scroll view that occupies whole screen. Content size is set to triple-width and same height. Inside the scroll view - there is container view and three table views - one per page. Only middle table view is visible initially. This allows me to use scroll view horizontal scrolling to navigate between the tables and vertical scrolling inside the middle table. I know that Apple doesn't really recommend putting UITableView inside UIScrollView, but in

问题 I was following this tutorial to make self sizing cells. I registered custom cell into table view and in the cell xib I gave every subview constraints manually. Please refer to the source code in GitHub Arranging 3 labels vertically in one cell's content view worked fine in iOS 9 but not in iOS 8 (both tested in device and simulator). In iOS 8 one cell does not have fitting height and not every label shows all it's full text. iOS 8 not fitting: iOS 9 as I expected: Any advice would be

问题 I have migrated all my image files to the asset catalogue. All of them are pdf vectors of size 1x. They are set to render as a Template. They show up fine everywhere in size and in color. But there is this one custom TableView Cell from a xib that I has 6 UIImageView s linking to 6 of these images from the catalogue. Somehow they don't respect the tint color, neither default nor custom. Tried changing them programmatically but didn't work either. These same images show up fine in another

问题 I'm trying to figure out why my whole navigation bar disappears when I start typing in the UISearchController.searchBar It loads properly and animates properly, but I lose the active NavBar when I start typing. Here's the code to load the searchController from viewDidLoad: UITableViewController *searchResultsController = [[UITableViewController alloc] initWithStyle:UITableViewStylePlain]; searchResultsController.tableView.dataSource = self; searchResultsController.tableView.delegate = self;

问题 I've just found out that in order to be able to have the description for your app in the app store say "This app is optimized for iPhone 6, and iPhone 6 Plus." you need to use a launch XIB or storyboard file for your launch images (per [Apple][1]). So, I've created a new Launch Screen xib and now I'm a little but since I usually do everything in code and don't use interface builder. I've deleted the default label that is inserted and dropped a UIImageView into the view. Now I'm wondering how

问题 I am trying to replace didRotateFromInterfaceOrientation with willTransitionToTraitCollection - in a UIViewController subclass - as doc says, but method is not get called when I am rotating device. Why? 回答1: If you're testing this on iPad it has regular trait collections for vertical and horizontal class for both orientations, thus it will not call this method when orientation changed. 来源： https://stackoverflow.com/questions/25634085/willtransitiontotraitcollection-not-get-called-why

问题 I thinking about port my App to Swift 2 and Xcode 7. But the device simulator only targets iOS 9 and I see no way to download iOS 8. I have parallel Xcode 6.3 installed. Is there any way to test and debug my app under iOS 8 with the device simulator? 回答1: Xcode release note says below thing, Simulator Xcode 7.0 beta does not support iOS 8.4 and earlier simulator runtimes.
