How to get path of image form Resource of main bundle

问题

i have an iPhone application in which i added images directory (Group) in to Resources (group). i want to access that images which is in images. I need a path to that images so i create a code like following.

NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"myImage1" ofType:@"png" inDirectory:@"images"];
NSLog(@"%@", imagePath);

Result :

(null)

i also tried this code

NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"myImage1" ofType:@"png"];

But this code gives me (null) result.

myImage1 's path is Resources/images/myImage1.png

I don't know what is the problem. Please suggest some fixes.

Adding image by following method solved my problem.

Right click on project in xcode and select Add Files to "project name".
Select your image file from computer local disk.
In the pop-up window make sure you select Copy items into destination group's folder and Create Folder References for any added folders and Add to targets.
click Add.

Then with bellow code i can retrieve my image.

For Objective-C version

[[NSBundle mainBundle] pathForResource:@"imageName" ofType:@"png"];

For Swift 4.0 version

Bundle.main.path(forResource: "imageName", ofType: "png")

for soultion....

Go to : Target -> "Build Phases" -> "copy bundle Resources" Then add that particular file here.

clean the project and RUN. It works.

and also see...

NSBundle pathForResource inDirectory gives nil

and also check...

NSString *path = [[NSBundle mainBundle] resourcePath];
NSFileManager *fm = [NSFileManager defaultManager];
NSError *error = [[NSError alloc] init];
NSArray *directoryAndFileNames = [fm contentsOfDirectoryAtPath:path error:&error];

print all value of this directoryAndFileNames and check your filename is exist in that or not....
