Get ranged string from text file without opening file with stringWithContentsOfFile

Question

I'm trying read text from text file. I used stringWithContentsOfFile to do this.

pathName        = [[NSBundle mainBundle] pathForResource:sample ofType:@"txt"];
entireContent   = [NSString stringWithContentsOfFile:pathName encoding:NSUTF8StringEncoding error:NULL];
entireChapter   = [entireContent substringWithRange:sourceRange];

Have any of you got another way to get string fast?

Answer 1

you can use NSFileHandle.

NSFileHandle *fileHandler = [NSFileHandle fileHandleForUpdatingAtPath:filePath];
[fileHandler seekToFileOffset:10];
NSData *data = [fileHandler readDataOfLength:10];
[fileHandler closeFile];

you can try this. then you can convert nsdata to string.
