Question

我正在尝试将布尔值写入plist文件。我的代码是：

 NSString *filePath = [self dataFilePath];
 if (filePath) 
 {
  if (check) 
  {
   NSLog(@"Clear");
   [item setObject:[NSNumber numberWithBool:NO] forKey:@"check"];
   [item writeToFile:filePath atomically: YES];
  }else{
   NSLog(@"Green");
   [item setObject:[NSNumber numberWithBool:YES] forKey:@"check"];
   [item writeToFile:filePath atomically: YES];
  }
  NSLog([[NSString alloc] initWithContentsOfFile:filePath]);
 }else{
  NSLog(@"write file was not found");
 }

我的文件路径是：

- (NSString *)dataFilePath 
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    return [documentsDirectory stringByAppendingPathComponent:@"CheckMark.plist"];
}

我用：

加载我的数组

- (void)viewDidLoad
{
 NSString *filePath = [self dataFilePath];
 NSLog(@"%@", filePath);

 if (![[NSFileManager defaultManager] fileExistsAtPath:filePath])
 {
  NSString *myPathInfo = [[NSBundle mainBundle] pathForResource:@"CheckMark" ofType:@"plist"];
  NSFileManager *fileManager = [NSFileManager defaultManager];
  [fileManager copyItemAtPath:myPathInfo toPath:filePath error:NULL];
 }    

 // load our data from a plist file inside our app bundle
 self.dataArray = [NSMutableArray arrayWithContentsOfFile:filePath];
 NSLog([[NSString alloc] initWithContentsOfFile:filePath]);
 NSLog(@"%@", filePath);
 NSLog(@"read dataArray");

每件事情都很好，除非我查看plist文件，没有任何变化。我正在将plist文件写入我的Documents目录。

感谢你给我的任何帮助。
