Question

使用apportable将iOS应用程序移植到Android时，如果已经本地化（不同语言的不同版本），则无法访问应用程序内的资源（它们无法在运行时加载）：

通过Xcode将本地化图像添加到项目中（不同语言的图像的不同版本） - apportable会将这些图像作为特定文件夹下的资源加载到.apk包中。例如：

assets/en.lproj/image.png        (generic english version)
assets/zh-Hans.lproj/image.png   (simplified chinese version)
assets/zh-Hant.lproj/image.png   (traditional chinese version)

尝试加载图片：

 UIImage *image = [UIImage imageNamed:imageName];   // This works under iOS but not under apportable

如果图像已如上所述进行了本地化，则返回nil。

以下是一个有效的临时解决方法：

Utils.h：

#if defined(ANDROID) && defined(WORKAROUND_APPORTABLE_LOCALIZED_IMAGES)
#define LOCALIZEDIMAGE LocalizedUIImage
@interface LocalizedUIImage : UIImage
+(UIImage *)imageNamed:(NSString *)imageName;
@end
#else
#define LOCALIZEDIMAGE UIImage
#endif

Utils.m：

#if defined(ANDROID) && defined(WORKAROUND_APPORTABLE_LOCALIZED_IMAGES)
#import <Foundation/Foundation.h>
@implementation LocalizedUIImage
+(UIImage *)imageNamed:(NSString *)imageName {
    UIImage *image = nil;
    if ([imageName rangeOfString:@"/"].location == NSNotFound) {
        NSLocale *locale = [NSLocale currentLocale];
        NSString *localeId = [locale localeIdentifier];
        NSString *localizedImageName = [[localeId stringByAppendingString:@".lproj/"] stringByAppendingString:imageName];
        image = [UIImage imageNamed:localizedImageName];
        if (image == nil) { // Retry for a generic language version (ie:   en  rather than   en_US  )
            NSUInteger hyphenatedLocale = [localeId rangeOfString:@"_"].location;
            if (hyphenatedLocale != NSNotFound) {
                NSString *localizedImageName = [[[localeId substringToIndex:hyphenatedLocale] stringByAppendingString:@".lproj/"] stringByAppendingString:imageName];
                image = [UIImage imageNamed:localizedImageName];
            }
        }
    }
    if (image == nil)
        image = [UIImage imageNamed:imageName];
    return image;
}
@end
#endif

使用者：

UIImage *image = [LOCALIZEDIMAGE imageNamed:imageName];

apportable - 如果资源图像已本地化，则无法访问它们
