Can i have a single NSMutableArray in my multiple views application?

If you are having multiple views in your application, and in that case you want to have a variable accessible to every view, you should always create a Model/Data(singleton) class and define the variable in it. Something like this :

//DataClass.h      

@interface DataClass:NSObject{

NSMutableArray *arrGlobal;

}

@property(nonatomic,retain) NSMutableArray *arrGlobal;

+(DataClass*)getInstance;

@end

//DataClass.m

@implementation DataClass

@synthesize arrGlobal;

static DataClass *instance =nil;

+(DataClass*)getInstance {

@synchronized(self){

if(instance==nil){ instance = [DataClass new];
}

}

return instance;

}

Now in your view controller you need to call this method as :

DataClass *obj= [DataClass getInstance];  
obj.arrGlobal = arrLocal;

This variable will be accessible to every view controller. You just have to create an instance of Data class.
