How to write to AppName-Info.plist

Question

NSBundle *mainBundle;
mainBundle = [NSBundl         


        

Answer 1

It's not possible.

By default the AppName-Info.plist isn't copied into the bundle in the Copy Bundle Resources phase of the build.

So if you want to have a plist which you can write to an option would be to create it at run time in the temporary files location and read/write to it there.

This is a great place to research how to do it.

You should consider NSUserDefaults or if you want to modify a bundled .plist try this.

    NSString* plistFilePath = nil;
NSFileManager* manager = [NSFileManager defaultManager];
if ((plistFilePath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"mySpecial/PathTo.plist"])) 
{
    if ([manager isWritableFileAtPath:plistFilePath]) 
    {
        NSMutableDictionary* infoDictioio = [NSMutableDictionary dictionaryWithContentsOfFile:plistFilePath];
        [infoDictio setObject:@"foo object" forKey:@"fookey"];
        [infoDictio writeToFile:plistFilePath atomically:NO];
        [manager setAttributes:[NSDictionary dictionaryWithObject:[NSDate date] forKey:NSFileModificationDate] ofItemAtPath:[[NSBundle mainBundle] bundlePath] error:nil];
    }
}

You should not modify your apps Info.plist file (or anything in your app's bundle) at runtime. This is bad practice and will also break your bundles code signature (which will result in not being able to launch the app anymore!).

If you want to store settings you should have a look at NSUserDefaults.
