问题
I am trying to write a macro to determine the device is 3.5 inch or 4 inch. Some thing similar below.
#define IOS_OLDER_THAN_6 ( [ [ [ UIDevice currentDevice ] systemVersion ] floatValue ] < 6.0 )
#define IOS_NEWER_OR_EQUAL_TO_6 ( [ [ [ UIDevice currentDevice ] systemVersion ] floatValue ] >= 6.0 )
Can someone help me. Please
回答1:
you can detect iphopne 3.5 inch or 4 inch using bellow:-
#define isiPhone5 ([[UIScreen mainScreen] bounds].size.height == 568)?TRUE:FALSE
you can check it using bellow method for example:-
if (isiPhone5)
{
// this is iphone 4 inch
}
else
{
//Iphone 3.5 inch
}
