iOS Question Call B4i sub from inline OBJC and return value

[CaptKronos]

How would I call from inline OBJC a B4i sub such as the following and have the inline code receive the sub's return value:

sub test as int
   return 1
end sub

Thanks.

The value will be returned from the call to raiseEvent.

Do you mean like this:

sub test as int
   return 1
end sub

#If OBJC 

-(NSInteger)testGettingVal
{
    NSInteger aNum;
    aNum=[self.bi raiseEvent:nil event:@"test:" params:@[]];
    return aNum;
}

#end if

I always get a value of 0 returned. I thought raising an event returned immediately (hence 0 rather than 1 being returned).

Your objective C code is wrong. What are you using inline code for?

 

[CaptKronos]

At the moment it is just to see whether it was possible to get a value from a b4i sub.

 

[Erel]

There is an extra colon in the in the sub name. There are other problems with this code (you will probably see a warning about unexpected synchronous event in the logs).

 

[CaptKronos]

Yes, sorry, you are correct. I rewrote my code on the fly to simplify it for the post and I missed the ":". My original code was passing a parameter. I also get the unexpected synchronous event message in the logs. However, I can't use raiseUIEvent because I believe that doesn't return a value.

I know nothing about Objective C. But, as I understand, inline OBJC allows direct calls like in other languages. For example, I added some statements in Erel's sample (see test.zip).

Hi Semen, that's exactly what I was looking for.

Thanks.
