检查上述链接。

以下是您的代码：

Check the above links. They may provide a solution to your problem.
Here is the code for you:

    totalCount = 0;
    NSArray *d = [[NSBundle mainBundle] pathsForResourcesOfType:@"jpg" inDirectory:nil];
    for(NSString *s in d)
    {
       if([[s lastPathComponent] hasPrefix:@"image_"]){
       totalCount++;
       }
    }

要从一个文件夹获取图像， 图片数量

For getting images froma a paticular folder, see this: count no.of images

    NSEnumerator *iter = [[NSFileManager defaultManager] directoryEnumeratorAtPath:[[NSBundle mainBundle] bundlePath]];
    int count = 0; // number of images
    for (NSString *path in iter) { // iterate through all files in the bundle
         if ([[path pathExtension] isEqualToString:@"png"]) { // test if the extension is "png"
            count++; // increment the number of images
            UIImage *img = [UIImage imageWithContentsOfFile:path];
            // do other things with the image
        }
    }

请参阅：

// create the route of localDocumentsFolder
NSArray *filePaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//first use the local documents folder
NSString *docsPath = [NSString stringWithFormat:@"%@/Documents", NSHomeDirectory()];
//then use its bundle, indicating its path
NSString *bundleRoot = [[NSBundle bundleWithPath:docsPath] bundlePath];
//then get its content
NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:bundleRoot error:nil];
// this counts the total of jpg images contained in the local document folder of the app
NSArray *onlyJPGs = [dirContents filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self ENDSWITH '.JPG'"]];
// in console tell me how many jpg do I have
NSLog(@"numero de fotos en total: %i", [onlyJPGs count]);
