第34月第26天 高效的 iOS 版本检测方法

1.

if ([[NSProcessInfo processInfo] isOperatingSystemAtLeastVersion:(NSOperatingSystemVersion){.majorVersion = 9, .minorVersion = 1, .patchVersion = 0}]) {
    NSLog(@"Hello from > iOS 9.1");
}

// Using short-form for the struct, we can make things somewhat more compact:
if ([NSProcessInfo.processInfo isOperatingSystemAtLeastVersion:(NSOperatingSystemVersion){9,3,0}]) {
    NSLog(@"Hello from > iOS 9.3");
}
