iOS獲取app圖標和啟動圖片名字（AppIcon and LaunchImages name）
編輯：IOS技巧綜合
[摘要]本文是對iOS獲取app圖標和啟動圖片名字（AppIcon and LaunchImage's name）的講解，對學習IOS蘋果軟件開發有所幫助,與大家分享。
在某種場景下，可能我們需要獲取app的圖標名稱和啟動圖片的名稱。比如說app在前台時，收到了遠程通知但是通知欄是不會有通知提醒的，這時我想做個模擬通知提示，需要用到icon名稱；再比如在加載某個控制器時，想設置該控制器的背景圖片為啟動圖片，需要用到啟動圖片名稱。
而事實上icon圖片放在系統AppIcon文件夾裡，啟動圖片放在系統LaunchImage文件夾裡，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，咱們先簡單粗暴點
假設當前項目只支持iPhone設備，並且只支持豎屏；而且當前項目裡已經設置好了AppIcon圖標和啟動圖片，
如何獲取icon圖標名稱和啟動圖片名稱呢 ？
上代碼和打印日志：
/** 獲取app的icon圖標名稱 */
- (void)getAppIconName{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲取app中所有icon名字數組
NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
//取最後一個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的啟動圖片名稱，並設置為本控制器背景圖片 */
- (void)getLaunchImageName{
NSString *launchImageName = @""; //啟動圖片名稱變量
CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;
//獲取與當前設備匹配的啟動圖片名稱
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-Portrait-736h";
}
if (launchImageName.length < 1) return; //設備啟動圖片為控制器的背景圖片
UIImage *img = [UIImage imageNamed:launchImageName];
self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}
打印當前只支持iPhone設備並且只支持豎屏場景下的所有啟動圖片信息：
/** 打印app裡面所有啟動圖片名稱信息 */
- (void)printAllLaunchImageInfo{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲取所有啟動圖片信息數組
NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
NSLog(@"launchImagesArr: %@", launchImagesArr);
/*
打印日志：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] 獲得，當前這裡面還包含了app的其他信息如版本、app名稱、設備類型、支持方向。。。
打印所有信息看看：
/** 打印app工程配置信息 */
- (void)printInfoDictionary{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSLog(@"%@", infoDict);
/*
打印日志：

CFBundleExecutable = TanTest;

AppIcon40x40,
AppIcon60x60
);
};
};
CFBundleIdentifier = "net.tan.xxx";
CFBundleInfoDictionaryVersion = "6.0";
CFBundleInfoPlistURL = "Info.plist -- file:///Users/PX/Library/Developer/CoreSimulator/Devices/7020368B-C160-42C0-B3C5-5F958FA82EF5/data/Containers/Bundle/Application/77D8C333-A6AF-4183-B79A-A5BEDCD08E1A/TanTest.app/";

CFBundleShortVersionString = "1.0";

CFBundleSupportedPlatforms = (

UILaunchImageFile = LaunchImage;
UILaunchImages = (

}
*/
}
----------- 接下來我們再來在app既支持iPhone和iPad設備，又支持橫屏和豎屏時，AppIcon和LaunchImage是怎樣的以及如何獲取 ---------
先上兩張圖，再上測試代碼：
測試代碼：
1、獲取AppIcon所有icon圖標名稱
/** 支持iPhone和iPad， 獲取app的icon圖標名稱 */
- (void)getAppIconName{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲取app中所有icon名字數組
NSArray *iconsArr = infoDict[@"CFBundleIcons"][@"CFBundlePrimaryIcon"][@"CFBundleIconFiles"];
//取最後一個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，支持橫屏和豎屏時，獲取啟動圖片，並設為背景圖片代碼
(iPhone設備只有在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圖片)
/**
支持iPhone和iPad, 支持橫屏、豎屏，
獲取app的啟動圖片名稱，並設置為本控制器背景圖片
*/
- (void)getLaunchImageName{
NSString *launchImageName = @""; //啟動圖片名稱變量
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
//獲取與當前設備匹配的啟動圖片名稱
//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;
//設備啟動圖片為控制器的背景圖片
UIImage *img = [UIImage imageNamed:launchImageName];
self.view.backgroundColor = [UIColor colorWithPatternImage:img];
}
3、打印出所有啟動圖片信息
/** 打印app裡面所有啟動圖片名稱信息 */
- (void)printAllLaunchImageInfo{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
//獲取所有啟動圖片信息數組
NSArray *launchImagesArr = infoDict[@"UILaunchImages"];
NSLog(@"launchImagesArr: %@", launchImagesArr);
/*
打印日志：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、打印所有配置信息
/** 打印app工程配置信息 */
- (void)printInfoDictionary{
NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
NSLog(@"%@", infoDict);
/*
