iOS Question Run Method error

[joilts]

Hi to all,

I'm trying to access a inline code with many parameters but I´m getting a not found error. Can you help me to find what I'm doing wrong?

Log Error:

The name of the method is wrong:

b=nome.RunMethod("thresholdImage:::::",Array(img ,thr, maxval, vType, ostsu))
