Read .strings file in Objective-C? - objective-c

Question

I'm creating a Mac app and I want to localize my Labels. I thought a .strings file would be a better choice. But I have trouble reading .strings file in Objective-C. I'm looking for a simpler method.
This is my .string file content:
"LABEL_001" = "Start MyApp";
"LABEL_002" = "Stop MyApp";
"LABEL_003" = "My AppFolder";
...
I have already looked at http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/LoadingResources/Strings/Strings.html.
This is my code:
NSBundle *bundle = [NSBundle mainBundle];
NSString *strFilePath = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",strFilePath,bundle, nil);
NSLog(#"STRING ::: %#",tt);
But the string tt gives "LABEL_001", I want "Start MyApp"
What am I doing wrong?

Answer 1

One. You have to name your file Localizable.strings in the <LANGUAGENAME>.lproj directory in the app bundle.
Two. Use the NSLocalizedString macro:
NSString *loc = NSLocalizedString(#"LABEL_001", nil);
Three. If nothing works, you can initialize an NSDictionary using a strings file, as a strings file is a special type of plist:
NSString *fname = [[NSBundle mainBundle] pathForResource:#"whatever" ofType:#"strings"];
NSDictionary *d = [NSDictionary dictionaryWithContentsOfFile:fname];
NSString *loc = [d objectForKey:#"LABEL_001"];

Answer 2

NSString *path = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSData *plistData = [NSData dataWithContentsOfFile:path];
NSString *error; NSPropertyListFormat format;
NSDictionary *dictionary = [NSPropertyListSerialization propertyListFromData:plistData
mutabilityOption:NSPropertyListImmutable
format:&format
errorDescription:&error];
NSString *stringname = [dictionary objectForKey:#"LABEL_001"];
I think it will be helpful to you.

Here the your code
NSBundle *bundle = [NSBundle mainBundle];
NSString *strFilePath = [[NSBundle mainBundle] pathForResource:#"Labels" ofType:#"strings"];
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",strFilePath,bundle, nil);
NSLog(#"STRING ::: %#",tt);
The problem here is the 2nd Param "strFilePath", change it to #"Labels" so the above code would become,
NSString *tt =NSLocalizedStringFromTableInBundle(#"LABEL_001",#"Labels",bundle, nil);
For reference, the following line copied from Apple Docs regarding table name,
"When specifying a value for this parameter, include the filename without the .strings extension."
hope this helps.

Simple Code
Just create a method as follows
- (void)localisationStrings
{
NSString* path = [[NSBundle mainBundle] pathForResource:#"localisation" ofType:#"strings"];
NSDictionary *localisationDict = [NSDictionary dictionaryWithContentsOfFile:path];
NSLog(#"\n %#",[localisationDict objectForKey:#"hello"]);
}
