无法在pyObjC中的对象上调用方法 [英] Can't call methods on objects in pyObjC

问题描述

当我在pyObjC代码中调用setDelegate_时，会得到一个AttributeError: 'tuple' object has no attribute 'setDelegate_'.

When I call setDelegate_ within my pyObjC code I get an AttributeError: 'tuple' object has no attribute 'setDelegate_'.

我的代码如下:

def createMovie(self):
        attribs = NSMutableDictionary.dictionary()
        attribs['QTMovieFileNameAttribute'] = '<My Filename>'
        movie = QTMovie.alloc().initWithAttributes_error_(attribs, objc.nil)
        movie.setDelegate_(self)

修改

我发现我不能对movie对象使用任何实例方法.

I Found out that i can't use any instance methods with the movie object.

推荐答案

从您的评论看来，QTMovie.alloc().initWithAttributes_error_实际上返回了一个由两个元素组成的元组，其中您想要的对象作为第一个元素，而其他对象则作为第二个元素元素(可能是错误?)

From your comment, it looks like QTMovie.alloc().initWithAttributes_error_ actually returns a two-element tuple, with the object you want as first element and some other object in the second element (possibly an error ?)

您应该能够像这样访问对象:

You should be able to access your object like that:

(movie, error) = QTMovie.alloc().initWithAttributes_error_(attribs, objc.nil)
