Updating binding on release of slider (but update text field continuously)?

I have a UI with an editable text field and a slider. I want the two to represent the same model property. I only want the model updated when the user exits the text field or lets go of the slider (which is what it does now). However, I'd like it if the text field would update continuously as th

Hi Josh, So you are not getting a parsing error, you're using the wrong mechanism. By calling abort you are setting the parsers error code, that code has nothing to do with the fact you are parsing some XML with "error" in it. I think you are confusing a Parsing Error and a valid XML stream wit

Thank you Quincey for your help! Looks like I was reading too much into the trace, thinking it was a bindings problem. Turns out I had done something like this: NSNumber *myNum = [[NSNumber alloc] init]; myNum = [prefs valueForKey:MinimumValue]; // retrieve NSNumber from shared defaults // do s

Yup. Right you are. Thanks. This was originally a singleton class where it wouldn't have shown up. That changed in redesign when we started switching different subclasses, which caused the problem. On 3/8/11 10:07 AM, "glenn andreas" wrote: > > On Mar 8, 2011, at 9:42 AM, Gordon Apple wrote

Hi Josh, I'm not sure that is the best place to be checking for a server/network error. If there was an API error, I would have thought the server would have returned valid XML with the error details, which should parse and not cause an parser error. I'd look at downloading the file, determine

I thought that NSError is just an output parameter, which is set only in case of errors. But in my completion handler block (see below) NSError MUST be initialized to nil, or it will NOT be set. The same code works as expected when NOT inside a block. #define REMOVE_BUG // if this i
