objective-c - Plist不会写入文件

Question

当我尝试这段代码时:

if ([[NSFileManager defaultManager] fileExistsAtPath:@"~/Library/Application Support/Staying Afloat/stats/static-stats.plist"] == NO) {
    NSMutableDictionary* tempDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:
                                     [[NSString alloc] initWithString:@"0"],@"completedGames",
                                     [[NSString alloc] initWithString:@"0"],@"floatsCollected",
                                     [[NSString alloc] initWithString:@"0"],@"sec",
                                     [[NSString alloc] initWithString:@"0"],@"subScore",
                                     [[NSString alloc] initWithString:@"0"],@"highScore",
                                     [[NSString alloc] initWithString:@"0"],@"longestSec", nil];

    [tempDict writeToFile:@"~/Library/Application Support/Staying Afloat/stats/static-stats.plist" atomically:YES];

    NSLog(@"written file");

}

输出为

2012-04-14 19:15:10.009 Staying Afloat[3227:9c07] written file

所以循环已运行，但文件未写入？ 谁能指出我将 plist 保存到非本地化位置的正确方向？

编辑:这是针对 mac 的

Answer 1

写入时需要使用 -(NSString *)stringByExpandingTildeInPath 扩展路径并检查文件是否存在。

编辑:阅读 NSDictionary 文档中的 writeToFile:automatically 方法。它说

If path contains a tilde (~) character, you must expand it with stringByExpandingTildeInPath before invoking this method.

所以只需做类似的事情

[tempDict writeToFile:[[NSString stringWithString:@"~/Library/Application Support/Staying Afloat/stats/static-stats.plist"] stringByExpandingTildeInPath] atomically:YES];
