ios - NSMutableArray crashes or have 0 data -

-

I am trying to use an unstable array of data to keep, and as my edit program uses it. 

  NSMutableArray * array; NSN * A = 1; NSN * B = 0; NSNumber * C = 3;

These methods have tried to define the array:

Method 1: 

  array = [[NSMUTABELARROL] init ]; [Array addObject: a]; [Array addObject: b]; [Array addObject: c]; // Results - Accidents

Method 2: 

  array = [[NSMUTABELARROL] initWithObjects: a, b, c, nil]; // result - [array number] return 0

method 3: 

  array = [[NSMUTABELARROL] INST]; Array = [NSMutableArray arrayWithObjects: a, b, c, zero]; // Results - Crash

It seems that if I do [[NSMutableArray alloc] init]; This will be the cause of the accident, I am not sure that there is a line which causes the crash.

How do I solve it?

  1. Start NSNumber objects like:

    A = [[NSNL Elok] INIT WITHIN: 1]; B = [[NSNumber Elok] Init Withd: 2]; C = [[NSNumber Elok] InitHath: 3];
  2. Code>

    or 

      [array addObject: a]; [Array addObject: b]; [Array addObject: c];

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
