objective-c - 目标c：无法用数组覆盖文件

Question

我是目标 c 的新手，我遇到的问题是，一旦我尝试保存它，我的“scores.xml”就不会被覆盖。我已将“scores.xml”导入我的项目，但一旦我尝试这样做，它就不会被覆盖。我究竟做错了什么？有没有人有任何想法？

- (void) writeHighScores:(NSString *)PlayerName{
NSString *highscorePath = [[NSString alloc]init];
NSArray * paths = [[NSBundle mainBundle] pathsForResourcesOfType: @".xml" inDirectory:@""];
for ( NSString * path in paths )
{
    highscorePath = [path substringToIndex:([path length])];
}

NSMutableArray *arrayFromFile = [NSMutableArray arrayWithContentsOfFile:highscorePath];

for (NSMutableArray *element in arrayFromFile){
    if (score > [[element objectAtIndex:1] intValue]){
        [element  replaceObjectAtIndex:0 withObject:PlayerName];
        [element  replaceObjectAtIndex:1 withObject:[NSString stringWithFormat:@"%d", score]];
        break;
    }
}
NSLog(@"Highscore path = %@",highscorePath);

    // Write array
    [arrayFromFile writeToFile:highscorePath atomically:YES];
}

Answer 1

1）您不能写入应用程序包。时期。写入其他地方（例如，写入 Documents 目录）。

2）这段代码应该做什么？这完全没有意义。

NSString *highscorePath = [[NSString alloc]init];
NSArray * paths = [[NSBundle mainBundle] pathsForResourcesOfType: @".xml" inDirectory:@""];
for ( NSString * path in paths )
{
    highscorePath = [path substringToIndex:([path length])];
}
