A discussion of best practice scenarios for device screen judgment by iOS code

The current development of the project for historical reasons are written in code UI, so judging equipment size has become an unavoidable task.

This is how I judge the size at the moment.

First, define an enumeration class that contains all the dimension types:

Enumeration types for screen dimensions typedef ns_enum (Nsuinteger, Screensizetype) {iphone4size,//Iphone5size 568, Ne6psize,//736};

Then write a static function to get the current dimension type:

+ (Screensizetype) Getscreensizetype {if (kScreenBounds.size.height = = 736) {return iphone6psize;} else if (kscreenbounds . Size.Height = = 667) {return iphone6size} else if (kScreenBounds.size.height = = 568) {return iphone5size;} return iPh One4size;}

And then get this type through the macro:

#define KSCREENSIZETYPE [Publicfunction Getscreensizetype]

Finally, when used this way:

int a = Kscreensizetype = = iphone6psize? 1:0;
