如何从iOS中的NSMainBundle中读取图像

Question

I have the structure like the following in my Xcode project.

I need to read all the images from project and need to store it in array.

I have used the following code from some other StackOverflow posts, but it's not working.

NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Images"ofType:@""];
NSDirectoryEnumerator *direnum;
direnum = [fileManager enumeratorAtPath: filePath];
imageFolder = [NSMutableArray new];
for(NSString *filename in direnum){
    if([[filename pathExtension] isEqualToString:@"png"]){
        [imageFolder addObject:filename];
    }
}
NSLog(@"Files in the folder %@",imageFolder);

I would appreciate, if any one help me to complete this.

Answer 1

it's simple to get all the images into a array

NSBundle *imageBundle=[NSBundle bundleWithPath: myBundlePath];
NSArray *allImageURLs=[imageBundle URLsForResourcesWithExtension:@"png" subdirectory:nil];

Answer 2

- (NSArray *)pathsForResourcesOfType:(NSString *)extension inDirectory:(NSString *)subpath将为您提供所需的数组。

NSArray *imagesArray = [[NSBundle mainBundle] pathsForResourcesOfType:@"png" inDirectory:@"Images"];

Answer 3

You can try below

NSArray *pathArray = [[NSBundle mainBundle] pathsForResourcesOfType:@"png" inDirectory:nil];

[pathArray enumerateObjectsUsingBlock:^(NSString *pathString, NSUInteger idx, BOOL *stop) {

    UIImage *yourImage = [[UIImage alloc] initWithContentsOfFile:pathString];
}];

Answer 4

Please use this code, hope it will work.

    NSString *dirPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"images"];
    NSError * error;
    NSArray * images =  [[NSFileManager defaultManager]
                  contentsOfDirectoryAtPath:dirPath error:&error];
