To Save HTML in local documents folder use this

- (void)SaveInfo :(NSString *)HTMLString
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory, @"htmlName.html"];
NSString *helloStr = HTMLString;
NSError *error;
[helloStr writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error];
}   

For getting the path and loading

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory, @"htmlName.html"];
NSString* htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
[documentsWebView loadHTMLString:htmlString baseURL:nil];

Save Your Html Stirng File to app/Library/Cache

NSString *str_html = @"html string";
//yourHTMLSourceCodeString String
NSString *str_lib_path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];    
//Get Library Path
NSString *str_cache_path = [str_lib_path stringByAppendingPathComponent:@"Caches"];
//Get Caches Path
NSString *str_file_path = [str_cache_path stringByAppendingPathComponent:@"file.html"];
//yourHTMLSourceCodeString File Path
[str_html writeToFile:str_file_path atomically:YES encoding:NSUTF8StringEncoding error:nil];
//Save your html string to file path
//then you should find the file in /var/mobile/Applications/(your app uuid)/Library/Caches/file.html

Load Html String File

NSString *str_lib_path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];    
NSString *str_cache_path = [str_lib_path stringByAppendingPathComponent:@"Caches"];
NSString *str_file_path = [str_cache_path stringByAppendingPathComponent:@"file.html"];
//your html string file path
NSString *str_html = [NSString stringWithContentsOfFile:str_file_path encoding:NSUTF8StringEncoding error:nil]
//Get your html file from local file

Check File Path

NSFileManager *fm = [NSFileManager defaultManager];
if (![fm fileExistsAtPath:str_cache_path])    //check caches folder is exist or not
{
    [fm createDirectoryAtPath:str_cache_path withIntermediateDirectories:NO attributes:nil error:nil]
    //create caches folder 
} 
//you can also use this method to check the html file is exist or not
