I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I…

Hi,
I made an Objective-C project for the iPhone. I had only one cpp class, the soundEngine taken from some Apple demo. Now I'm trying to merge OpenFeint which is coded in Objective-C++. As soon as I drop in the code without even referring to it from my code, when I hit Build, my Objective-C code…

Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation?
Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their…

What's the ObjectiveC syntax for specifying a protocol as an argument in a method?
Say I have 2 protocols, MyProtocol and MyProtocolCB:
@protocol MyProtocolCB <NSObject>
- (void) func;
@end
@protocol MyProtocol <NSObject>
- (void) register:(MyProtocolCB*) cb;
@end
I'm receiving this…

I am developing an iPhone application and I use HTML to display formatted text.
I often display the same webpage, but with a different content. I would like to use a template HTML file, and then fill it with my diffent values.
I wonder if ObjectiveC has a template system similar to ERB in Ruby.
That…

A few years ago I blogger about FizzBuzz, at the time the post was prompted by Scott Hanselman who had podcasted about how surprized he was that some programmers could not even solve the FizzBuzz problem within a reasonable period of time during a job interview. At the time I thought I would give…

Hi,
I'm new to objective-c and I saw the "new type" BOOL (YES, NO).
I read that this type is almost like a char.
For testing I did :
NSLog(@"Size of BOOL %d", sizeof(BOOL));
NSLog(@"Size of bool %d", sizeof(bool));
Good to see both display 1 (sometimes in C++ bool just an int and sizeof is 4)
So…

How can I in coq, prove that a function f that accepts a bool true|false and returns a bool true|false (shown below), when applied twice to a single bool true|false would always return that same value true|false:
(f:bool -> bool)
For example the function f can only do 4 things, lets call the…

I'm getting said error on this line "b = true". Now Why am I getting this error? Aren't I pointing to TurnMeOn and thus saying TurnMeOn = true?
class B{
void turnOn(bool *b){b = true}
};
int main(){
B *b = new B();
bool turnMeOn = false;
b->turnOn(&turnMeOn);
cout << "b = " <<…

If i have:
public static Func<SomeType, bool> GetQuery() {
return a => a.Foo=="Bar";
}
and a generic version
public static Func<T, bool> GetQuery<T>() {
return (Func<T,bool>)GetQuery();
}
how can I do the case?
The only way I have found so far is to try and combine…
