How to search images from Google Images and save selected images in documents directory?

Is there any API that can I use? Or any other way to do it?

Google API

Google Image Search API / JSON Developer's Guide.

You will have to display the images yourself as the result is a json response. However this will give you maximum control. The result will contain a thumbnail URL which you can use to show the preview.

Downloading images

Downloading images can be done in many ways:

The use of the Google API does only work under certain circumstances such as

"Applications that use this interface must abide by all existing Terms of Service. Most importantly, you must correctly identify yourself in your requests."

Saving Images

After receiving the results you can save the image to disk with:

NSString *aFileName = @"myImage.jpg";
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0]; 
NSString *path = [documentDirectory stringByAppendingPathComponent:aFileName];

[myImageAsData writeToFile:path atomically:YES];

alternatively if you've got the image as UIImage already:

NSData *myImageAsData = [NSData dataWithData:UIImagePNGRepresentation(anImage)];
[myImageAsData writeToFile:path atomically:YES];
