Question

我在xcode 5.1上编写了代码项目。我已经设置了所有控件的框架，这些控件在iPhone 5及更高版本中运行良好。但是当我在iPhone 4s上运行相同的项目时，我调整过的帧不适合iPhone 4s的屏幕。请有人帮我解决如何调整所有控件框架的简单方法。我是否需要手动更改所有控件的框架？

Answer 1

你可以使用多个xib / storyboard一个用于iphone5屏幕尺寸，另一个用于iphone4屏幕尺寸

然后像这样在appDelegate中进行更改

//如果使用故事板

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     UIStoryboard *storyBord;
    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
   {
         if(self.window.frame.size.height == 568)
             storyBord = [UIStoryboard storyboardWithName:@"Main_iPhone5" bundle:[NSBundle mainBundle]];
        else
             storyBord = [UIStoryboard storyboardWithName:@"Main_iPhone4" bundle:[NSBundle mainBundle]];
   }
   self.window.rootViewController = [storyBord instantiateInitialViewController];
   [self.window makeKeyAndVisible];

return YES;
}

//如果您使用.xib文件，那么每个视图controller.m文件都必须像这样初始化

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    {
        if([UIScreen mainScreen].bounds.size.height == 568)
            self = [super initWithNibName:@"FeedActivity_iPhone5" bundle:[NSBundle mainBundle]];
        else
            self = [super initWithNibName:@"FeedActivity_iPhone4" bundle:[NSBundle mainBundle]];
    }
}
return self;
}

你也可以选择使用自动布局，但这对你来说似乎很容易
