使用label.text值更改图像

Question

I have one lable called post.label.text = 5 . And I have 30 image view which size is 8 X 8. by default i have small dot image. When the value of my post.label.text is 5 , i need to change some of the 5 image out of 30 image should change to big dots image

ie:

total image small dots = 30 image dots

   should change from small to big dots = 5 image dots

I know to use if condition , but i have 30 images and for example if my post.label.text = 1 means i need to show only one small dot images to big dot image.

Please help me. i am new to ios.Thanks in advance!

My image declaation is like this:

@property (weak, nonatomic) IBOutlet UIImage *dot1;

       up to

@property (weak, nonatomic) IBOutlet UIImage *dot30;

And i did @synch of all dots 1 to 30 in .m file. after that what should i do to change the dots image based on the label.text value

I have more images so using if i cant change each image to chnage from small to big dots. IS there any idea to do. Please explain with some code.

I did in this way:

 if (sLabel.text > 10) {

     // imgV.image = [UIImage imageNamed:@"small dot.png"];

    }

but how i will do for all value for >1 , >2, so on. Please help me

Answer 1

 Try this Joseph

 self.post.text =@"5";
int value = [self.post.text intValue];
for (int i=0; i<value; i++) {
    UIImage *images =[UIImage imageNamed:[NSString stringWithFormat:@"dot%d",i]];
    imgV.image = images;
}

Create connection outlet of all image properties;

@property IBOutletCollection(UIImageView) NSArray *imgArray;

Next -

self.post.text = @"5";
int postValue = [self.post.text intValue];
for (int i=29; i>(29-postValue); i--)
{ 
    UIImageView *currImageView = [self.imgArray objectAtIndex:i];
      currImageView.image = [UIImage imageNamed:@"big dot.png"]; 
}
