如何将 imageWithContentsOfFile 用于动画中使用的图像数组? [英] How do I use imageWithContentsOfFile for an array of images used in an animation?

问题描述

这是我目前拥有的:

NSMutableArray *images = [[NSMutableArray alloc] initWithCapacity:21];

 for(int count = 1; count <= 21; count++)
{
    NSString *fileName = [NSString stringWithFormat:@"dance2_%03d.jpg", count];
    UIImage  *frame    = [UIImage imageNamed:fileName];
    [images addObject:frame];
}

UIImage imageNamed 给我带来了一些内存问题，我想切换到 imageWithContentsOfFile.

UIImage imageNamed is causing me some memory issues and I would like to switch to imageWithContentsOfFile.

我可以使用单个图像，但不能使用整个数组:

I can make it work with a single image, but not the whole array:

NSMutableArray *images = [[NSMutableArray alloc] initWithCapacity:21];

for(int count = 1; count <= 21; count++)
{
    NSString *fileName = [[[NSBundle mainBundle] bundlePath] stringByAppendingString:@"/dance2_001.jpg"];
    UIImage  *frame    = [UIImage imageWithContentsOfFile:fileName];
    [images addObject:frame];
}

非常感谢任何帮助！谢谢！

Any help is greatly appreciated! Thanks!

推荐答案

for(int i = 1; i <= 21; i++)
    {
        [images addObject:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"dance2_%03d", i] ofType:@"jpg"]]];
    }
