Answer 1

To access the NSMutableArray from one class to another class use following code.

In the first view controller in which u have declared the object of NSMutableArray, declare the property and synthesize for the same as below,

//In FirstViewcontroller.h class,

@property (nonatomic, strong) NSMutableArray *arrData;

//In FirstViewcontroller.m class

@synthesize arrData;

Also FirstViewcontroller object should be global so you can create the object of FirstViewcontroller in app delegate file.

//appdelegate.h

@property (nonatomic, strong) FirstViewcontroller *objFirst;

//appdelegate.m

@synthesize objFirst;

FirstViewcontroller *objFirst=[[FirstViewcontroller alloc]init];

Now in SecondViewcontroller in which you have to access array, create the share object of Appdelegate file

//SecondViewcontroller.m

 AppDelegate *app = (AppDelegate*)[[UIApplication sharedApplication] delegate];

Then use will get the required array as below,

app.objFirst.arrData

This is your required array I hope it will help you.
