nib

I have a NIB file, with some class (SomeClassView : UIView) set as the custom class of the top level view of the NIB. SomeClass has IBOutlets that I use to hookup subviews of SomeClass that I lay out in Interface Builder. I instantiate SomeClass like this: - (id)initWithFrame:(CGRect)frame { self = [[[[NSBundle mainBundle] loadNibNamed:@"SomeClassView" owner:nil options:nil] objectAtIndex:0] retain]; // "SomeClassView" is also the name of the nib if (self != nil) { self.frame = frame; } return self; } Now say I subclass SomeClass with SubClassView. I add a method to SubClassView called -(void

I was trying to figure out how to create a custom view using xib files. In this question the next method is used. NSBundle.mainBundle().loadNibNamed("CardView", owner: nil, options: nil)[0] as! UIView Cocoa has the same method,however, this method has changed in swift 3 to loadNibNamed(_:owner:topLevelObjects:) , which returns Bool , and previous code generates "Type Bool has no subscript members" error, which is obvious, since the return type is Bool. So, my question is how to a load view from xib file in Swift 3 First of all the method has not been changed in Swift 3 . loadNibNamed(_:owner

I have a nib-based table view cell which I created in Interface builder. I set the class of the table view cell to FooTableViewCell which extends from UITableViewCell . In FooTableViewCell I override the init method like this: -(id)init{ if ((self = [super init])){ // My init code here } return self; } I now expected that my gets called, when it is being instantiated. However the table view gets displayed but the method is never called. I could work around this but I would like to fully understand it and for me it's not clear how an object can come to live without the init method being called.

I am trying to publish an iOS application, however I receive these error when I try to validate my build: Nib file 'Main-iPad~.nib' was not found. Please ensure the specified file is included in the bundle with any required device modifiers appended to the filename Invalid Info.plist: The Info.plist may contain either UIMainStoryboardFile or NSMainNibFile, but it must not contain both keys. For more information, refer to the Information Property List Key Reference. It seems you have some stale entry in your Info.plist. Inspect it and delete the "Main nib file base name". Also make sure the nib

I'm getting this warning for every nib file that contains a UIActivityIndicator . The warning states: Unsupported Configuration: Hides when stopped but is neither hidden or animating What am i doing wrong? This means, You have set Hides when stopped . So there must be two states only, Hidden Animating But you have set neither Hidden nor Animating. See the image: It must be Hidden or Animating , If you have Checked Hides when stopped . You have selected hide when stopped option but you are never hiding activityindicator. set you setting as in attached image 来源： https://stackoverflow.com

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. When I correct it (below), the code compiles but the xib file doesn't load and the view is just transparent.

Since KVC is used to set outlets on the iPhone, there are 2 methods (that I know of) to make sure you've properly handled memory management. Specifically, I am referring to this article written by Aaron Hillegass. My question is which method do you use and what is your reasoning? Release all your outlets in dealloc and viewDidUnload (Make sure you set them to nil in viewDidUnload.) Make your outlets weak references Personally, I am leaning towards using weak references as it seems cleaner. I go with weak references. As you say its less cluttered and makes an already overly verbose code

After updating to Xcode 4.5 beta I have this error. I don't get the same error if I run the project by Xcode 4.3.3. 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "LocationList" nib but the view outlet was not set.' "LocationList" is a custom cell and the owner is a subclass of UITableViewController. I tried to subclass it to UIViewController and connect it to "view" in IB but then it doesn't recognize [self.tableview reloadData]; I had the same issue and what I did was just overriding the loadView method. So weird new Xcode cannot
