Hi, I have extended both NSString and NSMutableString with some convenience methods using categories. These added methods have the same name, but have different implementations. For e.g., I have implemented the ruby "strip" function that removes space characters at the endpoints for both but for NSString it returns a new string, and fo...
My understanding is that both of these create a NSMutableString, only the first one is owned by the system and the second one is owned by me (i.e. I need to release it). Is there any particular reason why I should use one or the other, on the face of it it seems easier to use the first? Also is the first better as it gives the compiler a...

My strings are fine, but when they get added to an array a weird grouping of "\n\t\t" gets added to the end. So the string "Apple", becomes "Apple\n\t\t" when I look at the array description. Whats the deal with that? and how do I fix it? Addition: Its XML code. It seemed like [currentPlace appendString:string]; would get the right pa...
I have some sensitive data I want to clear directly after use. Currently, the sensitive data is in the form of NSString. NSString is in my understanding immutable, meaning that I can't really clear the data.

Is anyone aware of a category on NSString or NSMutableString that allows for templating? I'd like to create a template and use tags for variables, then "apply" a KVC-compliant object against the string to have the variables replaced. Or another way of asking... How is templating currently done in the iPhone / Objective-C universe? Is ...
