How to get unique identifiacation number of iphone

问题

I want to get unique id of iphone.currently I am using Display.getInstance().getUdid(); but it gives different unique id each time I install an application on iphone. Can you please let me how to resolve it?

回答1:

You can no longer get the Unique id per device because of apples revised security policy . identifierForVendor is the best alternative you can go for. You can try

UIDevice *device = [UIDevice currentDevice];

NSString  *currentDeviceId = [[device identifierForVendor]UUIDString];

回答2:

You can get it by calling this function:

UIDevice.currentDevice().identifierForVendor

回答3:

getUDID() returns a faux number that can't be made unique due to Apple's restrictions.
