关于ios：将保存在plist中的NSNumbers转换为整数

Converting NSNumbers saved in a plist to integers

- (NSString *)dataFilePath
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
return [documentsDirectory stringByAppendingPathComponent:kFilename];
}
- (void)applicationWillTerminate:(NSNotification *)notification
{
NSMutableArray *array = [[NSMutableArray alloc] init];

NSNumber *number = [NSNumber numberWithInt:points];
[array addObject:number];

[array writeToFile:[self dataFilePath] atomically:YES];
[array release];
}

阅读数据：
BestLabel.text将显示高分。我收到一个警告："赋值在没有强制转换的情况下从指针生成整数"

-(void)LoadData{
BestLabel.center = CGPointMake(150,300);

NSString *filePath = [self dataFilePath];
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
{
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:filePath];
loadint = [array objectAtIndex:0];
NSString *myString35 = [NSString stringWithFormat:@"%d", loadint];
BestLabel.text = myString35;
[array release];
}
}

我得到的示例代码是保存和加载文本字段没有问题。我想我可以做一个字符串到int转换，但这似乎是不必要的。谢谢你的帮助！

{
NSMutableArray * array = [[NSMutableArray alloc] init];

if (points > highscore){

NSString *myString35 = [NSString stringWithFormat:@"%d", points];
[array addObject:myString35];
}else {
NSString *myString35 = [NSString stringWithFormat:@"%d", highscore];
[array addObject:myString35];
}

NSNumber *number = [NSNumber numberWithInt:GreenBlot.center.x];
[array addObject:number];
NSNumber *number2 = [NSNumber numberWithInt:GreenBlot.center.y];
[array addObject:number2];

现在加载：

NSString *filePath = [self dataFilePath];
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
{
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:filePath];
BestLabel.text = [array objectAtIndex:0];
highscore = [[array objectAtIndex:0] intValue];

lx = [[array objectAtIndex:1] intValue];
ly = [[array objectAtIndex:2] intValue];
GreenBlot.center = CGPointMake( lx,ly);

[array release];
}

lx和ly是整数。我首先尝试了CGPointMake([[array objectAtIndex：1] intValue]，[[array objectAtIndex：2] intValue])。相同的结果，GreenBlot以0,0为中心。知道为什么吗？
