NSLOG does not work - objective-c

Question

I try to get info for the array in the console but the NSLOg does not show anything. This is a class where i store data for the app. Here is the code.
#import <Foundation/Foundation.h>
#import "DAObject.h"
#interface DataModel : NSObject
#property (strong, nonatomic) NSArray *array;
#property (strong, nonatomic) NSArray *array2;
#end
and in the .m file
#import "DataModel.h"
#implementation DataModel
- (id)initWithCoder:(NSCoder *)decoder {
if (self = [super init]) {
}
return self;
}
- (NSArray *) _array
{
DAObject *obj1 = [[DACityObject alloc] init];
obj1.name = #"Obj1";
DACityObject *obj2 = [[DACityObject alloc] init];
obj2.name = #"Obj2";
_array = #[ obj1, obj2];
for (int i = 0; i < [_array count]; i++)
{
NSLog(#"Item %d = %#", i, [_array objectAtIndex:i]);
}
return _array;
}
- (NSArray *) array2 {
_array2 = [[NSArray alloc] initWithObjects:#"icon1.png", #"icon2.png",#"icon3.png", nil];
for (int i = 0; i < [_array2 count]; i++) {
NSLog(#"Item %d = %#", i, [_array2 objectAtIndex:i]);
}
return _array2;
}
#end
Where is the problem? I can't figure it out.

You need to access from anywhere to that getters, after that you will see logs.
For example try to do that in your AppDelegate.m
#import "DataModel.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
DataModel *data = [DataModel new];
data.array;
data.array2;
}
