Question

我的代码：

dict=[[NSMutableArray alloc]init];
    dict= _array;
    NSLog(@"%@",dict);


     colorimage = [dict objectAtIndex:0];
    [_b1 setBackgroundImage:colorimage forState:UIControlStateNormal];


     colorimage1 = [dict objectAtIndex:1];
     [_b2 setBackgroundImage:colorimage1 forState:UIControlStateNormal];

     colorimage2 = [dict objectAtIndex:2];
    [_b3 setBackgroundImage:colorimage2 forState:UIControlStateNormal];

      colorimage3 = [dict objectAtIndex:3];
     [_b4 setBackgroundImage:colorimage3 forState:UIControlStateNormal];

  int  j=0;


}
-(IBAction)button1:(id)sender{
    k++;
    [img addObject:colorimage];




    [sender setBackgroundImage:[UIImage imageNamed:@"apple.png"] forState:UIControlStateNormal];
    [self check];

}

单击button1时，需要将图像数据存储在NSMutableaArray中。我需要比较两个数组。那么如何在Objective-c中的NSMutableArray中存储图像的值。

Answer 1

将图像存储在数组中：

NSMutableArray * imagesArray =[[NSMutableArray alloc]init];
[imagesArray  addObject:[UIImage imageNamed:@"image.png"]];
[imagesArray  addObject:[UIImage imageNamed:@"image1.png"]];  
[imagesArray  addObject:[UIImage imageNamed:@"image2.png"]];

比较两个数组：

if ([array1 isEqualToArray:array2])
{
    NSLog(@"equal");
}
else
{
    NSLog(@"Not equal");
}

将值存储在nsarray objective-c中
