Iphone plist写操作中的问题

我正在向plist写入一些数据（字符串），如下所示：

NSError *error = nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *pathProduct = [documentsDirectory stringByAppendingPathComponent:@"unicurd.plist"];           

NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:pathProduct])
    {
    NSString *bundlePath=[[NSBundle mainBundle] pathForResource:@"unicurd" ofType:@"plist"];
        [fileManager copyItemAtPath:bundlePath toPath:pathProduct error:&error];

    }


    NSString *recipiBookMark= pageURL;

    NSMutableDictionary *recipieBM = [[NSMutableDictionary alloc] init];
    [recipieBM setObject:recipiBookMark forKey:@"BookMarks"];

    BOOL filewrite = [recipieBM writeToFile:@"unicurd.plist" atomically:YES];
    if(filewrite)
    {
        //do somthing
    }
}

但它不是写在文件上的。filewrite的值显示为YES，但在plist中，它只显示item0和值字段为空。

请这样尝试

 [recipieBM writeToFile: pathProduct atomically:YES];    

编辑：

// Create the new dictionary that will be inserted into the plist.
NSMutableDictionary *nameDictionary = [NSMutableDictionary dictionary];
[nameDictionary setValue:@"John Doe" forKey:@"fullName"];
[nameDictionary setValue:@"555 W 1st St" forKey:@"address"];

// Open the plist from the filesystem.
NSMutableArray *plist = [NSMutableArray arrayWithContentsOfFile:@"/path/to/file.plist"];
if (plist == nil) plist = [NSMutableArray array];
[plist addObject:nameDictionary];
[plist writeToFile:@"/path/to/file.plist" atomically:YES];

您应该写入从documents目录获得的文件路径

if(![fileManager fileExistsAtPath:pathProduct])
    {
    NSString *bundlePath=[[NSBundle mainBundle] pathForResource:@"unicurd" ofType:@"plist"];
        [fileManager copyItemAtPath:bundlePath toPath:pathProduct error:&error];

    }


    NSString *recipiBookMark= pageURL;

    NSMutableDictionary *recipieBM = [[NSMutableDictionary alloc] init];
    [recipieBM setObject:recipiBookMark forKey:@"BookMarks"];

    BOOL filewrite = [recipieBM writeToFile:pathProduct atomically:YES];
    if(filewrite)
    {
        //do somthing
    }
}

您正在尝试写入应用程序的捆绑包，这在iOS中是不允许的。看一下答案。谢谢！！！它正在写入，但当我第二次写入时，它会覆盖以前写入的数据。但我需要将下一个数据作为新条目写入plist。我应该在哪里使用数组？你可以根据我上面的代码放一些代码吗？不要使用字符串，而是使用我这样写的数组：bookmarkary=[[NSMutableArray alloc]init]；[书签数组addObject:pageURL]；NSMutableDictionary*recipieBM=[[NSMutableDictionary alloc]init]；[recipieBM setObject:bookMarkArray forKey:@“书签”]；BOOL filewrite=[recipieBM writeToFile:pathProduct原子性：是]；if（filewrite）{//do somthing}
