推荐答案
写入文件:
Write to a file:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
// the path to write file
NSString *myFile = [documentsDirectory stringByAppendingPathComponent:@"myFile"];
[data writeToFile:myFile atomically:YES];
阅读文件:
Read a file:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"MyFile" ofType:@"txt"];
NSData *myData = [NSData dataWithContentsOfFile:filePath];
if (myData) {
// do something useful
}
