Memory size (sizeof) Analysis of classes in C ++, size of Space sizeof First, determine the space occupied by each data type. For example, whether int occupies 2 bytes or 4 bytes space: In TC, int Is 2 bytes (mainly because TC is 16 bits, so int type should also be 16 bits)In VC ++, int Is 4 bytes, because most of the software in modern operating systems is 32 bi

Xcode 6 AutoLayout Size Classes, xcodeautolayout 1. Basic Concepts Before the appearance of iPad and iPhone 5, iOS devices only have one size. We only need to consider the device direction when making screen adaptation. Many applications do not support redirection. In this way, there will be no screen adaptation work.

My favorite Xcode6 feature is the new size classes concept, and with it, we've solved "how can I quickly write apps for so many different screen sizes and directions." They also let you create a generic app in a storyboard. By federating with the new Adaptive screen controller, it is easier to rely on interface builder than against it, simplifying the layout of your application.Each view controller in the a

1. Basic ConceptsiOS devices have only one size before the ipad and iphone 5 appear. The only thing we need to consider when making screen adaptations is the direction of the device. Many applications do not support steering, so there is no screen-fit job at all. With the launch of the ipad and iphone 5, and the next iphone 6, the screen

In IOS8, the new size classes feature, which is an abstraction of all of the current iOS device sizes, is also an abstraction, think about how many iOS-sized devices you have now: Iphone4-5-6-6plus, ipad, ipad Mini, IWatch, It must be a terrible thing to write a different layout for a particular device, as before.Now,

the following situations: When you need to show a lot of content and the size is not fixed; The program needs to support screen rotation (mainly the ipad program, the iphone app landscape is a bit non-mainstream, also do not exclude.)

Customizing Image sets for Size ClassesADD images to a set of that is customized for display in different size classes supported by your app.The application also supports storing images in a custom collection for display in different size classes. In the set list,

Note that while the size of D is the same as virtual inheritance, the memory layout is different.Then, take a look at the VC compilerVC handles virtual table pointers more complex than GCC, which determines whether virtual table pointers are shared in an inheritance relationship based on virtual inheritance , while pointers to virtual base cla
