需要帮助解决一个简单的问题!它具有以下标准:

1)点击iframe中的图像链接更改父页面,单击另一个iframe图像链接将父级更改为另一个页面(见下文).

这可能听起来很简单,但我现在用Google搜索了几天,并查看了许多论坛.代码可以是html css或js,但请尽可能简单地保留任何答案,并发布一个完整的工作示例,因为我是新手编码或重新编码测试网站:http://www.howiepotter.com/parent. HTML

-(IBAction)play:(id)sender
{

    thumbImageView.alpha=0.0;

    NSString *stringvideo=[NSString stringWithFormat:@"http://streaming-service",[[NSUserDefaults standardUserDefaults]valueForKey:@"VideoIdselected"]];

    NSString *videoURLString = stringvideo;

       NSURL *url = nil;

  url = [NSURL URLWithString:videoURLString];





    self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:url];




    if (self.moviePlayerController)
    {
        /* Save the movie object. */
          [self setMoviePlayerController:self.moviePlayerController];


        [self installMovieNotificationObservers];

        /* Specify the URL that points to the movie file. */
        [self.moviePlayerController setContentURL:url];


        [self.moviePlayerController setMovieSourceType:MPMovieSourceTypeStreaming]; // for streaming



        self.moviePlayerController.controlStyle = MPMovieControlStyleEmbedded;

        // [self.videoPlayer setMovieSourceType:MPMovieSourceTypeStreaming];

      // self.moviePlayerController.shouldAutoplay = YES;

        [self.moviePlayerController.view setFrame: CGRectMake(0, 0, 320,160)];



        [self.moviePlayerController setFullscreen:NO animated:YES];

        [self.moviePlayerController view].backgroundColor = [UIColor lightGrayColor];

        [self.view addSubview:self.moviePlayerController.view]; …

我是Ruby on Rails的新手,我正在尝试制作我的第一个应用程序.我运行任何rails generate命令时都会遇到问题.我收到以下错误

MyUsers-MacBook-Pro:MyApp MyUser$ rails generate devise:install

我最近在我的项目中为我的应用程序的Lite版本创建了一个新目标.现在,当我将.ipa上传到TestFlight,以便将其分发给我的设计师时,我得到:

无效的IPA:embedded.mobileprovision中的keychain-access-group与您的二进制文件不匹配.

我觉得发生这种情况的原因似乎是因为新的目标.有谁知道我需要改变什么才能让它发挥作用？

我正在尝试模仿facebook ios侧面菜单并让它正常工作但是我遇到的问题是我无法将侧面菜单发送到后面,正如另一个问题所讨论的那样在SO iphone facebook侧面菜单中使用目标c.我没有使用建议的库,而是使用建议的代码.我有

- (void)viewDidLoad
{
    NSLog(@"View Did Load is running");
    activitySpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
    activitySpinner.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
    activitySpinner.center = self.view.center;
    [self.view addSubview:activitySpinner];

    SideMenuView *myDelegate = [[SideMenuView alloc] init];
    [self setSideMenuDelegate:myDelegate];
    //set the delegate's currentViewController property so that we can add a subview to this View. 
    [sideMenuDelegate setCurrentViewController:self];

    //sideMenu = [[SideMenuView alloc] initWithNibName:@"SideMenuView" bundle:nil];
    [self.view addSubview:myDelegate.view];
    [self.view sendSubviewToBack:myDelegate.view];

    [super viewDidLoad];
    self.searchDisplayController.searchBar.scopeButtonTitles = nil;

    [self fetchCustomers];
    // Do any additional setup after loading …

两者之间有区别吗？

NSArray *myArray = @[objectOne, objectTwo, objectThree];

和

NSArray *myArray = [NSArray arrayWithObjects:objectOne, objectTwo, objectThree, nil];

一个比另一个更受欢迎吗？

有没有一种简单的方法可以轻松地将FMDB结果executeQuery:SELECT * ...放入字典中？

FMResultSet *appointmentResults = [[DataClass getDB] executeQuery:@"SELECT * FROM Appointments WHERE date = ?",currDateString];
while ([appointmentResults next]) {
    //Create dictionary
    //Add dictionary to array for later use
}

我想知道是否有一种方法可以使字典键为列名,值为列值.优选地,不必在一段时间内遍历每一行.

我有以下菜单样式布局,模仿脸书.我想在左侧有一个阴影,如下所示,但我使用层阴影的代码使应用程序LAGGY.我一直无法找到一个好的替代解决方案.有没有人可以选择创建不影响应用程序性能的drophadow？

[self.navController.view.layer setShadowOffset:CGSizeMake(0, 1)];
[self.navController.view.layer setShadowColor:[[UIColor darkGrayColor] CGColor]];
[self.navController.view.layer setShadowRadius:8.0];
[self.navController.view.layer setShadowOpacity:0.8];

上面的代码是我目前使用的代码导致应用程序性能问题.

下面的图像是我想要实现的,但不必使用上面的代码.

获取UITableView中最顶部的标题或索引的最准确方法是什么？我不是指索引0处的部分,而是滚动时当前固定在顶部的部分标题.

请帮我.我有方法:

-(void) getCurrentOrientation{

    UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];

    if(orientation == UIInterfaceOrientationPortrait){
        NSLog(@"portrait");
    } else if(orientation == UIInterfaceOrientationLandscapeRight) {
        NSLog(@"LandscapeRight");
    } else if(orientation == UIInterfaceOrientationLandscapeLeft) {
        NSLog(@"LandscapeLeft");
    }   
}

但是当我调用这个getCurrentOrientation时抛出viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self getCurrentOrientation];

}

NSLog是空的.怎么了 ？我也试试

- (void)viewDidLoad
{
    [super viewDidLoad];

    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

    if ( ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait)) {
        NSLog(@"portrait");

    } else if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) 

    {
        NSLog(@"LandscapeRight"); 
    }

}

但那个varint也是空的.

我需要知道哪个ORIENTATION用户启动APP!

拜托,给我任何建议.
