讀寫plist文件

Question

我需要寫入plist文件，然後再讀出數據... 但是，每當我測試我的應用程序，寫入plist文件的數據永遠不會保存退出iPhone模擬器！你能告訴我爲什麼存在這個問題的原因嗎？在運行期間，數據似乎被寫入並且完全正確地讀取。但我的plist文件從不更新！ 我可能做錯了。那麼你能指導我通過在cocos2d中創建一個plist並讀寫整數嗎？ 謝謝！

爲了節省：

+ (void)save:(Example *)exampleobject { 
    NSString * directory = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
    NSString * path = [directory stringByAppendingPathComponent:@"Example.plist"]; 
    [NSKeyedArchiver archiveRootObject:exampleobject toFile:path]; 
} 

要檢索

+ (Example *)load { 
    NSString * directory = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
    NSString * path = [directory stringByAppendingPathComponent:@"Example.plist"]; 
    NSData * data = [NSData dataWithContentsOfFile:path]; 
    Example * exampleobject = [NSKeyedUnarchiver unarchiveObjectWithData:data]; 
    if (!exampleobject) { exampleobject = [[Example alloc] init]; } 
    return exampleobject; 
}
