xib

问题 I've search a lot but I can't do yet. I've my .xib UI with some buttons, separated from main storyboard. I need to perform an action when I press one of this button and show another view. How can I do this directly from code such ad inside an IBAction? 回答1: You can't perform segues from XIB to Storybaord, Instead of it you need 1) Get Storyboard's instance. 2) Instantiate a ViewController that is inside the Storyboard (By using Storyboard ID). 3) Push that ViewController to to your navigation

问题 I have created simple view using interface builder. This view has one label. Do you know how to create init method for this class ? I wrote my own version but I am not sure that it is correct or not. @interface AHeaderView () @property (nonatomic, weak) IBOutlet UILabel *descriptionLabel; @end @implementation AHeaderView - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // add subview from nib file NSArray *nibContents = [[NSBundle mainBundle] loadNibNamed:@

问题 Can someone help me with this scenario? *There is a button, which when tapped, slides opens up a UIView, with the tapped button still to its left. *This button when tapped again, makes the UIView slide back. 回答1: What you describe is easy. Let's call the view that slides in from the right a drawer ("drawerView"). Set up the drawer view as a child view of your view controller's main view. Make that "drawer" view a container view. Put everything you want inside it. (Your text view, buttons, etc

问题 I have an app that has a settings page in which the user can change the app's language. Eventually, the direction of the xibs will change. To explain a bit more, if the language is English for example, the direction will be LTR; However if it's Arabic, it will be RTL. Question What is the best approach to achieve this? Approaches tried with issues NSUserDefaults : When setting the language to "ar-SA", the direction changes successfully but only when it's called in the main class. When I do it

问题 I am curious to know if anyone has any experience comparing the load time performance of iPhone apps with views laid out in NIBs vs. views laid out entirely programmatically (i.e. instantiating UITextView, adding it to the view, instantiating UIButton, adding it to the view…). If I want a simple app to load lightning fast, would it be better to forgo using a NIB (well, XIB technically) and instead create view elements programmatically? Is the time spent loading and parsing a NIB sufficient

问题 I have a UIView defined in a .xib file. I need to set translatesAutoresizingMaskIntoConstraints = NO . This means that the frame is not translated to constraints so I need to set the size constraints by myself. I have created a working category method for a UIView : -(NSArray*)setSizeConstraints:(CGSize)size { NSLayoutConstraint* height = [NSLayoutConstraint constraintWithItem:self attribute:NSLayoutAttributeHeight relatedBy:0 toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1

问题 Situation: I am starting XCode, creating a new project for the iPhone (view application) and loading the XIB file into the IB. I manipulate the view (adding a label with the string "hello"), save, build, run the application, everything is fine. Now i am localizing the XIB. What i do: right-click on the xib-file, adding the desired language and after that, i have two XIB files in my XCode. Looks absolut perfect, just as it is shown in my iPhone Programming book ("the big nerd ranch"). I do

问题 I currently have an XCode project that uses XIBs and would like to start using Storyboards. Is there a good way to move my XIB files into the Storyboard? 回答1: You can do this manually one view controller at a time. Copy the view from xib (⌘ c). Go to storyboard and create a new view controller in it. Then select the view of that view controller and hit paste (⌘ v). 来源： https://stackoverflow.com/questions/7798400/transitioning-from-xib-files-to-storyboard

问题 I have subclassed UIViewController into a new class, PageViewController (I'm writing a simple book app). I want to add a new view loaded from a nib file and am using the following code. It works. PageViewController *viewController1 = [[UIViewController alloc] initWithNibName:@"Page1" bundle:nil]; [viewController1.view setUserInteractionEnabled:YES]; [self.view addSubview:viewController1.view]; However, the first line is wrong because I should be calling alloc on PageViewController.
