What is the best way of loading images from the application main bundle. I am using [UIImage imageNamed: "image.png"]; But I have heard that this is not good in terms of memory usage and performance. Can anyone please give his/her feedback on it? My application reads lots of images from main bundle at launch time. I want to make this process as efficient as possible. Best Regards UIAdam If you want to try loading the images without caching, you can use: [[UIImage alloc] initWithContentsOfFile:@"image.png"]; This could be slightly faster loading the image for the first time, since it doesn't

I am trying to copy a folder in my NSBundle which contains quite a number of images. I tried doing it with these codes. NSFileManager *fileManager = [NSFileManager defaultManager]; NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *documentDBFolderPath = [documentsDirectory stringByAppendingPathComponent:@"Images"]; NSString *resourceDBFolderPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Images"]; [fileManager copyItemAtPath

Using the Settings app in the iPhone simulator to switch languages is a PITA way of testing localization tweaks. I'm trying to figure out a way to switch localizations (en/fr/es/etc) on the fly in my app with a debug setting without restarting the app. NSBundle provides ways of requesting localized resources from an arbitrary localization, e.g. - (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension inDirectory:(NSString *)subpath forLocalization:(NSString *)localizationName But I find no equivalent for the string management subsystem. It sounds from these questions that

during the progress of my app I decided to change from using a UIStoryboard to .xib file, and now I get the error: Could not find a storyboard named 'Main' in bundle NSBundle How can I fix this problem within the Simulator part of my app? Remove the "Main storyboard file base name" or "UIMainStoryboardFile" Key from your info.plist file.

I am working on getting the facebook API working for iOS, and the FB registration page requires the Bundle ID of the project. How can I get this information? I read something about getting it at run time, but is there a way to get Xcode to tell me this information, or is it held in a plist somewhere. I am not using the default bundle id, I remember setting it while I created the project. Aks If you are trying to get it programmatically , you can use below line of code : objective C NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier]; Swift 3.0 : let bundleIdentifier = Bundle

I have an Xcode 5 unit test project and some test xml files related to it. I've tried a bunch of approaches but I can't seem to load the xml files. I've tried the following which does not work NSData* nsData = [NSData dataWithContentsOfFile:@"TestResource/TestData.xml"]; NSString* fileString = [NSString stringWithContentsOfFile:@"TestData.xml" encoding:NSUTF8StringEncoding error:&error]; Also if I try to preview all the bundles using [NSBundle allBundles] the unit test bundle does not appear in the list? I tried to create a separate resource bundle and I can't seem to locate it

I want to ask a question about the objective C on iPhone application. I read some sample program in the apple developer website and I found that almost all of the applications contains a word called 'NSBundle' and 'mainBundle', and I really don't understand the meaning of this word. Can anyone tell me about that? Thank you very much. JeremyP A bundle is a structure used for packaging software on Mac OS X. Applications, frameworks and plug-ins are all different kinds of bundles. Bundles may contain executable code, resources, header files and other stuff (including other bundles) if you so wish

How can we check if a file is present in the external bundle loaded in the app or not before fetching it? If you only want to know if it's there so you can decide whether to load it or not, I'd just attempt to load it and check if the object returned is nil. If it is, you know it doesnt exist in the bundle. To check if a file exists in the bundle, use the NSBundle class. NSString *path = [[NSBundle mainBundle] pathForResource:@"somefileinbundle" ofType:@"png"]; if (!path) NSLog(@"Unable to find file in bundle"); Having said that however, it's typically a bad idea to check if a file exists

Can I replace images in bundle at run time? Basically, I have some images part of my bundle and also I will have them from the server if there is any change in the image. Can I place them in the bundle at run time so that I need not to change my code to pick the image? You cannot change the contents of an Application bundle. It is however possible to store the images in the Application's documents folder. Then you'll be able to overwrite those images in case they need to be changed. There are two ways to achieve this: At launch, check whether the image files exist in the documents directory.
