尝试循环遍历图像并将其添加到数组中

Question

I'm trying to loop through my mutable array and add image objects 3-81. Heres my code. Can someone tell me why its not working?

- (instancetype)init {
    self = [super init];
    if (self) {
        self.imageData = [NSMutableArray arrayWithObjects:[UIImage imageNamed:@"image1.gif"],       [UIImage imageNamed:@"image2.gif"],  nil];

        for (int i = 3; i <= 81; i++) {
            NSString *imageName = [NSString stringWithFormat:@"image%i", i];
            [self.imageData addObject:[UIImage imageNamed:imageName]];
        }
    }
    return self;
}

You are adding images named "image1.gif" and "image2.gif". However, in your loop you are adding images named "image3", "image4", "image5", etc. The missing ".gif" is likely the problem.

NSString *imageName = [NSString stringWithFormat:@"image%i.gif", i];
