Create a new subclass of UIPopoverBackgroundView Declare the following in your interface: +(UIEdgeInsets

What's up with CITemperatureAndTint having vector inputs?

由 和自甴很熟 提交于 2019-12-29 05:26:09
问题 OK, so the Core Image filter Temperature and Tint has two inputs, neutral and targetNeutral. However, my biggest issue is the fact that they're both two-component vectors, meaning each has two numeric inputs. I would expect the first to be from say 2500 to 10000. What would the vector be for? 回答1: The essential purpose of performing temperature and tint adjustment is to correct the white balance of a captured image: to account for the ambient illumination of the scene and adjust colors so

Problems with Page Cache in iOS 5 Safari when navigating back / unload event not fired

由 百般思念 提交于 2019-12-28 05:10:16
问题 tl;dr - Safari on iOS 5 is caching so hard, it is breaking my site. I am struggling with the way the Safari browser in iOS 5 deals with back forward cache, which they call "Page Cache".
