How do I convert an NSMutableString to NSString when using Frameworks?
- by BWHazel
I have written an Objective-C framework which builds some HTML code with NSMutableString which returns the value as an NSString.
I have declared an NSString and NSMutableString in the inteface .h file:
NSString *_outputLanguage; // Tests language output
NSMutableString *outputBuilder;
NSString *output;
This is a sample from the framework implementation .m code (I cannot print the actual code as it is proprietary):
-(NSString*)doThis:(NSString*)aString num:(int)aNumber {
if ([outputBuilder length] != 0) {
[outputBuilder setString:@""];
}
if ([_outputLanguage isEqualToString:@"html"]) {
[outputBuilder appendString:@"Some Text..."];
[outputBuilder appendString:aString];
[outputBuilder appendString:[NSString stringWithFormat:@"%d", aNumber]];
}
else if ([_outputLanguage isEqualToString:@"xml"]) {
[outputBuilder appendString:@"Etc..."];
}
else {
[outputBuilder appendString:@""];
}
output = outputBuilder;
return output;
}
When I wrote a text program, NSLog simply printed out "(null)". The code I wrote there was:
TheClass *instance = [[TheClass alloc] init];
NSString *testString = [instance doThis:@"This String" num:20];
NSLog(@"%@", testString);
[instance release];
I hope this is enough information!
