iOS Question B4Ih2xml problem parsing header file

walterf25 · Feb 15, 2020

I have the following line in my header file of a library i'm trying to wrap:

setChartData:

- (void)setChartData:(B4IArray *)xValues : (B4IArray *)yValues;

But when i run the file through the B4Ih2xml jar I get the following error:

Error parsing array type: B4IArray *
parser._parsetype (java line: 763)
java.lang.IllegalStateException: No match found

Why do I get this error, does the B4Ih2xml not recognize the B4IArray type?

Any ideas?

Thanks,
Walter

You need to add the array type as a comment. Example:

B4X:

- (B4IArray */*byte,1*/)ReadBytes:(NSString *)Dir :(NSString *)FileName;
- (B4INativeObject *)RunMethod:(NSString *)MethodName :(B4IArray */*NSObject,1*/)Params;

What about if I change B4IArray to NSMutableArray *
I've tried doing that and in B4I i see the NSMutableArray is changed to Object, but when I try calling the function i get an error saying something like No selector found.

Any ideas?
