我有一个UIImageView我正在制作动画（使用UIView's commitAnimations）并且我正在使用NSObject's移动它以performSelectorInBackground:获得更好的性能。现在我的问题是，是否可以在UIImageView使用单独的线程移动时更改修改图像？一切似乎都运行良好，但我想问一下，因为我知道你应该在启动新线程时复制数据。
我正在使用UIImageView's setImage:，它没有记录但有效。UIImageView.image使用财产会更好吗？提前致谢 ：）
Setting a property is equivalent to invoking its corresponding setter method. It's documented, you just haven't noticed it: having a (read-write) property named 'image' implicitly means having an
- (UIImage *)image;
and a
- (void)setImage:(UIImage *)img;
method.
You should always perform UI operations on the main thread. Even if it works now, it may break once.
