Code adaption for different iOS versions: _ IPHONE_ OS _VERSION_MAX_ALLOWED and _ IPHONE_8_0. 360os adaption Models

Code adaption for different iOS versions: _ IPHONE_ OS _VERSION_MAX_ALLOWED and _ IPHONE_8_0. 360os adaption Models

Currently, developers only want the lowest version to support ios8. ios8. after iOS9 and iOS10 are released, some new APIs and Some APIs are discarded. To ensure compatibility, sometimes the Code must be written to determine different iOS versions, or only the specified iOS version can be compiled or executed.

You need to use the following methods ):

Example:

// Use this method after ios8.0 to replace willRotateToInterfaceOrientation: duration: This method # if _ IPHONE_ OS _VERSION_MAX_ALLOWED> = 80000 // The View Controller is rotated to a certain size-(void) viewWillTransitionToSize) size withTransitionCoordinator :( id <UIViewControllerTransitionCoordinator>) coordinator {[super viewWillTransitionToSize: size withTransitionCoordinator: coordinator]; if (size. height> size. width) {NSLog (@ "------- the current device direction is landscape screen -------");} else {NSLog (@ "------- the current device direction is landscape screen -------");} # endif

 

_ IPHONE_ OS _VERSION_MIN_REQUIRED: Minimum iOS version requirements

_ IPHONE_ OS _VERSION_MAX_ALLOWED: Maximum iOS version allowed
