loadview

问题 I'm trying to replace a UIViewController root view with a subclassed UIView. In the iPhone SDK's UIViewController Class Reference, within it's Overview section, this is stated: You use each instance of UIViewController to manage a full-screen view. For a simple view controller, this entails managing the view hierarchy responsible for presenting your application content. A typical view hierarchy consists of a root view—a reference to which is available in the view property of this class—and

问题 I have UIViewController without a xib, and I'm using loadView to build my UI that creates and adds two scroll views. The thing is, the main view frame size is not changing when rotation happens. I mean, I'm setting initial frame size for the main view in loadView (portrait mode: frame size width = 320, height = 480). After rotation to landscape orientation, the view main frame size isn't changing and is the same as in portrait mode. Here's my loadView: -(void)loadView{ CGRect screenBounds = [

问题 First I want to load a view file into a variable, then I need to create a new file by writing the data to new file.ie,Like creating a copy of a view file. $vPath = "home/muhammed/desktop/newfolder"; $ViewData=$this->load->view('test/show',TRUE); mkdir($vPath); write_file("$vPath/test.php", $ViewData); But the code given is not working. 回答1: change: $ViewData=$this->load->view('test/show',TRUE); to $ViewData=$this->load->view('test/show', "", TRUE); as second parameter of load->view is data

问题 I am trying to implement the imagepickercontroller inside a UITabBarController. So far, so good.... In my ViewController, where I initiate the imagePickerController and then place in my TabBarViewController tabbar array, I implemented the "loadview" method: - (void)loadView{ self.arController = [[IFAugmentRealityController alloc] initWithViewController:self]; [self showCamera]; [self initOverlayController]; self.picker.delegate = self; [self.view addSubview:self.picker.view]; } - (void

问题 I want to set the view property of a UIViewController at runtime. I have an .xib file with two views, and I want my UIViewController subclass that owns the .xib file to decide which UIView to use at runtime. I thought I could do this in loadView by just saying if(some condition) self.view = thisView; else self.view = thatView; but that didn't work. How can I do this? 回答1: If you want to choose your view dynamically, set it inside -[UIViewController loadView] . A word of caution though:

问题 I am trying to implement a widgets library using load->view. I know I can use include to call directly the file and avoid the vars cache issues but just wondering why it does not work. Here is how I have structured my code: My Controller: class Page extends MY_Controller { public $data = array(); public function __construct() { parent::__construct(); ... $this->load->library('widgetmanager'); } public function index($slug = '') { echo $this->widgetmanager->show(2); echo $this->widgetmanager-

问题 In the docs for loadView , Apple states: Your custom implementation of this method should not call super. So I tried calling [super loadView] in my loadView method. Nothing bad seemed to happen and there was no warning. I'm using a view created programatically, in loadView , not from a NIB. What (if any) bad things actually happen when I call [super loadView] ? 回答1: Calling [super loadView] will cause the UIViewController implementation of loadView to run. Among other things, this is the

问题 I am having this issue with loading up table content in UITableViewController . I have created UITableViewController without the xib. In loadView I am calling a function which generates the array of data to be displayed. And from that array in tableView:cellForRowAtIndexPath: I am trying to load the cells.

问题 I've created a custom view called GraphView . All I get is a blank black screen when the view is loaded. Here is my code: in GraphViewController.m: @synthesize graphView, graphModel; - (void)loadView { GraphView *aGraphView = [[GraphView alloc] initWithFrame:CGRectZero]; self.view = aGraphView; self.graphView = aGraphView; [aGraphView release]; } I'm not sure why I just get a black screen when I try to implement loadView in GraphViewController.m 回答1: You're not setting a frame for the
