Renaming all files and directories in NSLibraryDirectory - ios

Question

How can I rename all files and directories to lower case in NSLibraryDirectory\myFolder?
I found that I can to use:
[[NSFileManager defaultManager] moveItemAtPath:oldPath toPath:[oldPath lowercaseString] error:&error];
to renaming directories.
NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:path error:nil];
To getting array with directory contents but how I can check if directoryContent[0] is directory or file.

Answer 1

You could use this to check if a NSUrl is a directory or file:
for (NSURL *item in directoryContent) {
NSString *path = [item path];
BOOL isDir;
if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir]) {
if (isDir) {
NSLog(#"%# is a directory", path);
} else {
NSLog(#"%# is a file", path);
}
} else {
NSLog(#"%# does not exist", path);
}
}
UPDATE:
To rename all contents of your directory you could use this:
NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:path error:nil];
BOOL isDir;
for (NSURL *item in directoryContent) {
if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir]) {
if (isDir) {
// create a new directory with lowercase name,
// move contents of old directory to the new one
// then delete the old directory
} else {
[[NSFileManager defaultManager] moveItemAtPath:path toPath:[path lowercaseString] error:&error];
}
}
}

//Call [self purgeDirectory:__NSLibraryDirectoryPath];
+(void)purgeDirectory:(NSString *)directoryPath __deprecated_msg("For debug purposes only") {
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:directoryPath error:&error];
for (NSString *itemPath in directoryContent) {
BOOL isDir;
if ([[NSFileManager defaultManager] fileExistsAtPath:itemPath isDirectory:&isDir]) {
if (isDir) {
[self purgeDirectory:itemPath];//subdirectory
} else {
[[NSFileManager defaultManager] removeItemAtPath:itemPath error:&error];
}
}
}
}
