iOS獲得AppIcon and LaunchImages name(app圖標和啟動圖片名字)

編輯：關於JAVA

iOS獲得AppIcon and LaunchImage's name(app圖標和啟動圖片名字)。本站提示廣大學習愛好者：（iOS獲得AppIcon and LaunchImage's name(app圖標和啟動圖片名字)）文章只能為提供參考，不一定能成為您想要的結果。以下是iOS獲得AppIcon and LaunchImage's name(app圖標和啟動圖片名字)正文

在某種場景下，能夠我們須要獲得app的圖標稱號和啟動圖片的稱號。好比說app在前台時，收到了長途告訴然則告訴欄是不會有告訴提示的，這時候我想做個模仿告訴提醒，須要用到icon稱號；再好比在加載某個掌握器時，想設置該掌握器的配景圖片為啟動圖片，須要用到啟動圖片稱號。

　　而現實上icon圖片放在體系AppIcon文件夾裡，啟動圖片放在體系LaunchImage文件夾裡，取這些圖片的稱號和其他普通資本圖片稱號紛歧樣。

　　為了便利舉例子，我們先簡略粗魯點

假定以後項目只支撐iPhone裝備，而且只支撐豎屏；並且以後項目裡曾經設置好了AppIcon圖標和啟動圖片，

若何獲得icon圖標稱號和啟動圖片稱號呢？

上代碼和打印日記：

/** 獲得app的icon圖標稱號 */
- (void)getAppIconName{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲得app中一切icon名字數組
NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
//取最初一個icon的名字
NSString *iconLastName = [iconsArr lastObject];
//打印icon名字
NSLog(@"iconsArr: %@", iconsArr);
NSLog(@"iconLastName: %@", iconLastName);
/*
打印日記：
iconsArr: (
AppIcon29x29,
AppIcon40x40,
AppIcon60x60
)
iconLastName: AppIcon60x60
*/
}
/** 獲得app的啟動圖片稱號，並設置為本掌握器配景圖片 */
- (void)getLaunchImageName{
NSString *launchImageName = @""; //啟動圖片稱號變量
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
//獲得與以後裝備婚配的啟動圖片稱號
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;
//裝備啟動圖片為掌握器的配景圖片
UIImage *img = [UIImage imageNamed:launchImageName];
self.view.backgroundColor = [UIColor colorWithPatternImage:img]; 
}

打印以後只支撐iPhone裝備而且只支撐豎屏場景下的一切啟動圖片信息：

/** 打印app外面一切啟動圖片稱號信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲得一切啟動圖片信息數組
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日記：啟動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，項目AppIcon圖標和啟動圖片信息，都可以從 [[NSBundle mainBundle] infoDictionary] 取得，以後這外面還包括了app的其他信息如版本、app稱號、裝備類型、支撐偏向。。。

打印一切信息看看：

/** 打印app工程設置裝備擺設信息 */
- (void)printInfoDictionary{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 NSLog(@"%@", infoDict);

---------- 接上去我們再來在app既支撐iPhone和iPad裝備，又支撐橫屏和豎屏時，AppIcon和LaunchImage是如何的和若何獲得 ---

先上兩張圖，再上測試代碼：

測試代碼：

1、獲得AppIcon一切icon圖標稱號

/** 支撐iPhone和iPad， 獲得app的icon圖標稱號 */
- (void)getAppIconName{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲得app中一切icon名字數組
 NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
 //取最初一個icon的名字
 NSString *iconLastName = [iconsArr lastObject];
 //打印icon名字
 NSLog(@"iconsArr: %@", iconsArr);
 NSLog(@"iconLastName: %@", iconLastName);
 /*
 打印日記(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、獲得在支撐iPhone和iPad開辟，支撐橫屏和豎屏時，獲得啟動圖片，並設為配景圖片代碼

(iPhone裝備只要在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圖片)

/** 
 支撐iPhone和iPad, 支撐橫屏、豎屏，
 獲得app的啟動圖片稱號，並設置為本掌握器配景圖片
 */
- (void)getLaunchImageName{
 NSString *launchImageName = @""; //啟動圖片稱號變量
 CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height; //屏幕高度
 CGFloat screenWidth = [UIScreen mainScreen].bounds.size.width; //屏幕寬度
 //裝備界面偏向
 UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
 BOOL isPortrait = UIInterfaceOrientationIsPortrait(orientation);// 能否豎屏
 BOOL isLandscape = UIInterfaceOrientationIsLandscape(orientation);//能否橫屏
 //獲得與以後裝備婚配的啟動圖片稱號
 //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;
 //裝備啟動圖片為掌握器的配景圖片
 UIImage *img = [UIImage imageNamed:launchImageName];
 self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}

3、打印出一切啟動圖片信息

/** 打印app外面一切啟動圖片稱號信息 */
- (void)printAllLaunchImageInfo{
 NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
 //獲得一切啟動圖片信息數組
 NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
 NSLog(@"launchImagesArr: %@", launchImagesArr);
 /*
 打印日記：啟動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、打印一切設置裝備擺設信息

以上所述是小編給年夜家引見的iOS獲得AppIcon and LaunchImage's name(app圖標和啟動圖片名字)，願望對年夜家有所贊助，假如年夜家有任何疑問請給我留言，小編會實時答復年夜家的。在此也異常感激年夜家對網站的支撐！
