Gpuimage Custom FiltersGpuimage is an open source IOS framework based on GPU image and video processing. Because the GPU was used to process images and videos, it was very fast, and its author, Bradlarson, said that the processing speed on iPhone4 was 100 times times that of CPU processing (Coreimage can also use the GPU to process images, but I think coreimage is still slow )。 In addition to the speed advantage, Gpuimage also offers a lot of great image processing

Css3, Use Cases of background-clip/background-origin, which can be explained in general and css3backgroundclip Let's not talk about the usage of background-clip/background-origin. Let's talk about css background. 1 The width and height of p are 100 PX, and the color range is 100 *, right? What if padding-top: 10px is added to p? So the current height is 110, and the color background is 100*110, right? Because the background includes padding, it is cr

the background of the Actionbar, the problem here is that the api-7 and api-11 code is written in the same file, the result can not be compiled through eclipse, The solution is to divide this themes.xml into multiple files, and the project automatically generates VALUES-V7, Values-v11, VALUES-V14, Themes.xml can be divided into several different versions of the different values, different devices of different styles is probably the way to achieve it?The original text on the StackOverflow:EDIT :

representation of polymorphism between a parent class and a subclass, and overloading overloading is a representation of polymorphism in a class. If you define a method in a subclass that has the same name and arguments as its parent class, we say that the method is overridden (overriding). When an object of a subclass uses this method, the definition in the subclass is called, and for it the definition in the parent class is "masked". If more than one method with the same name is defined in a
