Answer 1

如果你有NSString,你可以做到

NSString *myString; //Assuume the string you want to write is this
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"myfile.txt"];
[myString writeToFile:path atomically:YES];

Answer 2

看NSString的writeToFile:atomically:encoding:error:方法.用法如下:

[myString writeToFile:myPath atomically:YES encoding:NSUTF8StringEncoding error:&myError];
