没有界面生成器的链接图像

最近我在我的应用程序中使用故事板和xibs进行了切割。虽然这样做很容易将图像链接到正确的图像名称。现在我想把它们联系起来，没有那些麻烦。在这里和谷歌搜索相当一段时间没有太大的成功。没有界面生成器的链接图像

这些图像将用于应用程序启动后启动屏幕以防止白色闪光（与IB一起工作完美）。在我的.h文件中，我做到了。

@property (nonatomic, retain) UIImageView *splash4InchPortrait;

我将如何从图像我有我的应用程序宣告形象的名字说，[email protected]？

这是我在这两个文件中都有的。只是想让你知道我在做什么。

您声明形象首先创建一个UIImage后的UIImageView图像属性设置为图片中指出@ggrana。

所以无论

UIImage *myImage = [UIImage imageNamed:@"splash4InchPortrait"]; 
[splash4InchPortrait setImage:myImage];

或

[splash4InchPortrait setImage:[UIImage imageNamed:@"splash4InchPortrait"]];

您也可以initalize的- (void)loadView {}方法内您的UIImageView的。

确保您设置了您的UIImageView的框架，并将它们添加为您的UIViewControllerview的子视图。

最后一个注意事项：如上所述，当您定义图像时，不需要指定@2x。编译器会根据它运行的设备为你做这些事情。

编辑：好吧尝试添加到您的实施文件。

- (void)loadView { 
    [super loadView]; 

    UIImage *myImage = [UIImage imageNamed:@"[email protected]"]; 
    self.splash4InchPortrait = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 568.0f)]; 
    [self.splash4InchPortrait setImage:myImage]; 
    [self.view addSubview:self.splash4InchPortrait]; 
    [self.view bringSubviewToFront:self.splash4InchPortrait]; 



}

最后，确保你，如果你没有在dealloc方法使用ARC释放你的形象。

- (void)dealloc { 
     [self.splash4InchPortrait release]; 
}

这应该让你开始一条坚实的道路。

因为我刚刚使用只是代码而勉强和我在一起。为了做到这一点，我需要改变什么？上面提供的代码。 – ChrisOSX

所以在你的实现文件（.m）中你有viewDidLoad方法。你可以在它内部或按照我的建议做，使用 - （void）loadView {}方法。为了清楚起见，我将修改我的帖子。给我一点时间。 – kushyar

不走，仍然没有出现。我只是试图让Default-568h图像现在显示。多数民众赞成我用我的启动画面。正如你在代码中看到的，我有很多其他的启动画面。 – ChrisOSX

我会建议您做到以下几点：

  • 创建一个自定义视图来封装您的组件连接在一起。
  • 您的自定义视图可以由组成其他自定义视图。

然后，而不是设置所有这些组件的隐藏属性，您可以定义一个单独的方法，并从控制器调用它。

模型 - 视图 - 控制器模式的精神在于控制器是模型和视图之间薄薄的“粘合”层。它的目的是在它们之间来回分流/翻译信息。

加载图片

注意：您只需要选择图像资源的名字 - 的UIImage会选择正确的资源（@ 2倍，568h @ 2X等）。

关于选择使用正确的图像：如果从Jetbrains的使用AppCode IDE，你可以做到以下几点：

    打字后

  • 按Ctrl空间[UIImage的imageNamed：@“”]得到一个可供选择的图像文件列表。在图像文件名

  • 按住Ctrl键单击，以使其在IDE和显示尺寸，像素深度等

（您可以也可能在Xcode做到这一点 - 不知道，因为它不是我的主要IDE）。
