How to save photo to directory [duplicate] - ios

Question

This question already exists:
Selecting Where to Save Photo to Directory using PickerView
Closed 8 years ago.
I created multiple directories using
NSArray *directoryNames = [NSArray arrayWithObjects:#"t",#"b",#"p",#"c", #"S", #"h", #"o",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
for (int i = 0; i < [directoryNames count] ; i++) {
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];
However I want to sort the photo that is displaying on the UIImage and sort it which the user select using pickerview. I want to know the code to save into these specific directory that I made. Any help is greatly appreciated!
Update I know that
To use your created directories anywhere in your app.
NSArray *directoryNames = [NSArray arrayWithObjects:#"tops",#"bottoms",#"right",#"left",nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
// This will return the folder name in the 0 position. In yours "tops"
NSString *topDirPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:0]];
// This will return the file path in your "tops" folder
NSString *filePath = [topDirPath stringByAppendingPathComponent:#"MYIMAGE"];
To store an image file
NSData *imageDataToStore = UIImagePNGRepresentation(image);
[imageDataToStore writeToFile:filePath atomically:YES];
I do not know where to declare my directory name

To save images to a file in a folder you need to get the data for the image (UIImageJPEGRepresentation) and then save that data to disk (writeToFile:atomically:).
