How to write in a txt-file, iOS 7
(1 answer)
Closed 8 years ago.
I want to write in a txt, but my code not working...
This is my code:
-(void)bestScore{
if(cptScore > bestScore){
bestScore = cptScore;
highScore.text =[[NSString alloc] initWithFormat: #" %.d", bestScore];
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"bestScore" ofType:#"txt"];
NSString *test = #"test";
[test writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:nil];
}
}
I have already a file named bestScore.txt in my folder "Supporting Files"
Can you help me please ?
Thanks
EDIT :
I can read my file "bestScore.txt" with this code :
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"bestScore" ofType:#"txt"];
NSString *textFromFile = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
highScore.text = textFromFile;
bestScore = [textFromFile intValue];

Try this:
-(void)bestScore{
if(cptScore > bestScore){
bestScore = cptScore;
highScore.text =[[NSString alloc] initWithFormat: #" %.d", bestScore];
NSString *filePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Library/Preferences/bestScore.txt"];
NSString *test = [NSString stringWithFormat:#"%#",bestStore];
NSError *error;
// save a new file with the new best score into ~/Library/Preferences/bestScore.txt
if([test writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error])
{
// wrote to file successfully
NSLog(#"succesfully wrote file to %#", filePath);
} else {
// there was a problem
NSLog(#"could not write file to %# because %#", filePath, [error localizedDescription]);
}
}
}
And to read the score back in, you can do:
NSString *filePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Library/Preferences/bestScore.txt"];
NSString *textFromFile = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
if(textFromFile)
{
highScore.text = textFromFile;
bestScore = [textFromFile intValue];
} else {
// if the file doesn't exist or if there's an error, initialize bestScore to zero
bestScore = 0;
highScore.text = #"";
}
