iOS獲取AppIcon and LaunchImage's name(app圖標(biāo)和啟動(dòng)圖片名字)

 更新時(shí)間:2016年08月30日 09:27:29   投稿:mrr  
這篇文章主要介紹了iOS獲取AppIcon and LaunchImage's name(app圖標(biāo)和啟動(dòng)圖片名字)的相關(guān)資料,非常不錯(cuò),具有參考借鑒價(jià)值,感興趣的朋友一起學(xué)習(xí)吧

在某種場(chǎng)景下,可能我們需要獲取app的圖標(biāo)名稱和啟動(dòng)圖片的名稱。比如說(shuō)app在前臺(tái)時(shí),收到了遠(yuǎn)程通知但是通知欄是不會(huì)有通知提醒的,這時(shí)我想做個(gè)模擬通知提示,需要用到icon名稱;再比如在加載某個(gè)控制器時(shí),想設(shè)置該控制器的背景圖片為啟動(dòng)圖片,需要用到啟動(dòng)圖片名稱。

  而事實(shí)上icon圖片放在系統(tǒng)AppIcon文件夾里,啟動(dòng)圖片放在系統(tǒng)LaunchImage文件夾里,取這些圖片的名稱和其他一般資源圖片名稱不一樣。

  為了方便舉例子,咱們先簡(jiǎn)單粗暴點(diǎn)

假設(shè)當(dāng)前項(xiàng)目只支持iPhone設(shè)備,并且只支持豎屏;而且當(dāng)前項(xiàng)目里已經(jīng)設(shè)置好了AppIcon圖標(biāo)和啟動(dòng)圖片,

如何獲取icon圖標(biāo)名稱和啟動(dòng)圖片名稱呢 ?

上代碼和打印日志:

/** 獲取app的icon圖標(biāo)名稱 */
- (void)getAppIconName{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲取app中所有icon名字?jǐn)?shù)組
NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
//取最后一個(gè)icon的名字
NSString *iconLastName = [iconsArr lastObject];
//打印icon名字
NSLog(@"iconsArr: %@", iconsArr);
NSLog(@"iconLastName: %@", iconLastName);
/*
打印日志:
iconsArr: (
AppIcon29x29,
AppIcon40x40,
AppIcon60x60
)
iconLastName: AppIcon60x60
*/
}
/** 獲取app的啟動(dòng)圖片名稱,并設(shè)置為本控制器背景圖片 */
- (void)getLaunchImageName{
NSString *launchImageName = @""; //啟動(dòng)圖片名稱變量
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
//獲取與當(dāng)前設(shè)備匹配的啟動(dòng)圖片名稱
if (screenHeight == 480){ //4,4S
launchImageName = @"LaunchImage-700";
}
else if (screenHeight == 568){ //5, 5C, 5S, iPod
launchImageName = @"LaunchImage-700-568h";
}
else if (screenHeight == 667){ //6, 6S
launchImageName = @"LaunchImage-800-667h";
}
else if (screenHeight == 736){ // 6Plus, 6SPlus
launchImageName = @"LaunchImage-800-Landscape-736h";
}
if (launchImageName.length < 1) return;
//設(shè)備啟動(dòng)圖片為控制器的背景圖片
UIImage *img = [UIImage imageNamed:launchImageName];
self.view.backgroundColor = [UIColor colorWithPatternImage:img]; 
}

打印當(dāng)前只支持iPhone設(shè)備并且只支持豎屏場(chǎng)景下的所有啟動(dòng)圖片信息:

/** 打印app里面所有啟動(dòng)圖片名稱信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲取所有啟動(dòng)圖片信息數(shù)組
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日志:?jiǎn)?dòng)圖片的名字是固定的
 launchImagesArr: (
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Portrait-736h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Landscape-736h";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-667h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{375, 667}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 480}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-568h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 568}";
  }
 )
 */
}

看到了,項(xiàng)目AppIcon圖標(biāo)和啟動(dòng)圖片信息,都可以從 [[NSBundle mainBundle] infoDictionary] 獲得,當(dāng)前這里面還包含了app的其他信息如版本、app名稱、設(shè)備類型、支持方向。。。

打印所有信息看看:

---------- 接下來(lái)我們?cè)賮?lái)在app既支持iPhone和iPad設(shè)備,又支持橫屏和豎屏?xí)r,AppIcon和LaunchImage是怎樣的以及如何獲取 ---

先上兩張圖,再上測(cè)試代碼:

測(cè)試代碼:

1、獲取AppIcon所有icon圖標(biāo)名稱

/** 支持iPhone和iPad, 獲取app的icon圖標(biāo)名稱 */
- (void)getAppIconName{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲取app中所有icon名字?jǐn)?shù)組
 NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
 //取最后一個(gè)icon的名字
 NSString *iconLastName = [iconsArr lastObject];
 //打印icon名字
 NSLog(@"iconsArr: %@", iconsArr);
 NSLog(@"iconLastName: %@", iconLastName);
 /*
 打印日志(29pt和40pt iPhone和iPad都用到;60pt --- iPhone, 76pt和83.5pt --- iPad):
 iconsArr: (
  AppIcon29x29,
  AppIcon40x40,
  AppIcon60x60,
  AppIcon76x76,
  "AppIcon83.5x83.5"
 )
 iconLastName: AppIcon83.5x83.5
 */
}

2、獲取在支持iPhone和iPad開發(fā),支持橫屏和豎屏?xí)r,獲取啟動(dòng)圖片,并設(shè)為背景圖片代碼

(iPhone設(shè)備只有在Plus, 即5.5英寸才有豎屏和橫屏兩套圖片,其他4、5、6豎屏橫屏共用一張啟動(dòng)圖片)

/** 
 支持iPhone和iPad, 支持橫屏、豎屏,
 獲取app的啟動(dòng)圖片名稱,并設(shè)置為本控制器背景圖片
 */
- (void)getLaunchImageName{
 NSString *launchImageName = @""; //啟動(dòng)圖片名稱變量
 CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height; //屏幕高度
 CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width; //屏幕寬度
 //設(shè)備界面方向
 UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
 BOOL isPortrait = UIInterfaceOrientationIsPortrait(orientation);// 是否豎屏
 BOOL isLandscape = UIInterfaceOrientationIsLandscape(orientation);//是否橫屏
 //獲取與當(dāng)前設(shè)備匹配的啟動(dòng)圖片名稱
 //4、4S 豎屏,橫屏
 if ((isPortrait && screenHeight == 480) || (isLandscape && screenWidth == 480)){
 launchImageName = @"LaunchImage-700";
 }
 //5、5C、5S、iPod 豎屏,橫屏
 else if ((isPortrait && screenHeight == 568) || (isLandscape && screenWidth == 568)){
 launchImageName = @"LaunchImage-700-568h";
 }
 //6、6S 豎屏,橫屏
 else if ((isPortrait && screenHeight == 667) || (isLandscape && screenWidth == 667)){
 launchImageName = @"LaunchImage-800-667h";
 }
 //6Plus、6SPlus豎屏
 else if (isPortrait && screenHeight == 736){
 launchImageName = @"LaunchImage-800-Portrait-736h";
 }
 //6Plus、6SPlus 橫屏
 else if (isLandscape && screenWidth == 736){
 launchImageName = @"LaunchImage-800-Landscape-736h";
 }
 //iPad 豎屏
 else if (isPortrait && screenHeight == 1024){
 launchImageName = @"LaunchImage-700-Portrait";
 }
 //iPad 橫屏
 else if (isLandscape && screenWidth == 1024){
 launchImageName = @"LaunchImage-700-Landscape";
 }
 if (launchImageName.length < 1) return;
 //設(shè)備啟動(dòng)圖片為控制器的背景圖片
 UIImage *img = [UIImage imageNamed:launchImageName];
 self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}

3、打印出所有啟動(dòng)圖片信息

/** 打印app里面所有啟動(dòng)圖片名稱信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲取所有啟動(dòng)圖片信息數(shù)組
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日志:?jiǎn)?dòng)圖片的名字是固定的
 launchImagesArr: (
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Portrait-736h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-Landscape-736h";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{414, 736}";
  },
  {
  UILaunchImageMinimumOSVersion = "8.0";
  UILaunchImageName = "LaunchImage-800-667h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{375, 667}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 480}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-568h";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{320, 568}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-Portrait";
  UILaunchImageOrientation = Portrait;
  UILaunchImageSize = "{768, 1024}";
  },
  {
  UILaunchImageMinimumOSVersion = "7.0";
  UILaunchImageName = "LaunchImage-700-Landscape";
  UILaunchImageOrientation = Landscape;
  UILaunchImageSize = "{768, 1024}";
  }
 )
 */
}

4、打印所有配置信息
