Question

我想从localizable.strings文件中读取文本。我正在从几个目录中收集用于翻译的字符串，并将文件放在一个.strings文件中。但后来我有几个相同翻译字符串的副本。我想以编程方式删除它。所以我需要从.strings文件中读取字符串（而不是注释），以及 - 然后对它们进行排序 - 删除重复的字符串然后创建一个新的.strings文件。

是否可以读取字符串文件并将字符串和翻译后的值保存在字典中。我的意思是任何读取.text文件的内置方法，只有“key”=“value”部分，避免使用/ * ... * /或#views部分。就像阅读配置文件一样。

Answer 1

  NSString *path = [[NSBundle mainBundle] pathForResource:@"Localizable"
                                                   ofType:@"strings"                                                       
                                              inDirectory:nil
                                          forLocalization:@"ja"];

  // compiled .strings file becomes a "binary property list"
  NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];

  NSString *jaTranslation = [dict objectForKey:@"hello"];

我很高兴在NSString类中找到一个优秀的API。代码如下。

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
// Insert code here to initialize your application 
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Localizable" ofType:@"strings"];
NSString *fileText = [NSString stringWithContentsOfFile:filePath encoding: NSUnicodeStringEncoding error:nil];
NSDictionary *stringDictionary = [fileText propertyListFromStringsFileFormat];

NSArray *allKeys = [stringDictionary allKeys];

NSArray *sortedKeys = [allKeys sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];

NSString *documentsDirectory;   
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);  
if ([paths count] > 0)  {       
    documentsDirectory = [paths objectAtIndex:0];       
}

NSString *outputPath = [documentsDirectory stringByAppendingString:@"/Localizable.strings"];
NSLog(@"Strings contents are writing to: %@",outputPath);
[[NSFileManager defaultManager] createFileAtPath:outputPath contents:nil attributes:nil];
NSFileHandle *outputHandle = [NSFileHandle fileHandleForWritingAtPath:outputPath];
[outputHandle seekToEndOfFile];

for(id key in sortedKeys){
    NSString *line = [NSString stringWithFormat:@"\"%@\" = \"%@\";\n", key, [stringDictionary objectForKey:key]];
    NSLog(@"%@",line);
    [outputHandle writeData:[line dataUsingEncoding:NSUnicodeStringEncoding]];
}
}

Swift解决方案

我按照@ jason-moore above回答的Objective-C代码创建了一个快速代码该解决方案是等效的。

guard let path = Bundle.main.url(forResource: "Localizable", withExtension: "strings", subdirectory: nil, localization: "ja") else {
            return nil
        }
guard let dict = NSDictionary(contentsOf: path) else {
        return nil
    }
guard let jaTranslation = dict.value(forKey: "hello") as? String else {
        return nil
    }

我想要的是一种从包文件中读取json到NSDictionary然后在UITextView内打印的方法。结果没有很好的格式化！

我使用了Karim上面的答案的一部分创建了一个在字符串中生成美化json的方法：

-(void)setText:(NSDictionary *)json
{
    NSArray *allKeys = [json allKeys];

    _beautyStr = @"";
    for(id key in allKeys){
       NSString *line = [NSString stringWithFormat:@"\"%@\" = \"%@\";\n", key, [text objectForKey:key]];
    _beautyStr = [NSString stringWithFormat:@"%@%@",_beautyStr, line];
    }

    NSLog(@"%@",_beautyStr);
}
