iPhone iOS 4 addTimeInterval已弃用

Question

I'm using addTimeInterval for creating local notification but it seems that it is now deprecated (iOS 4).

My code:

localNotif.fireDate = [now addTimeInterval:timeInterval];

Xcode's warning:

'addTimeInterval:' is deprecated (declared at /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSDate.h:27)

What should I use instead? Thanks.

Answer 1

The method has been renamed to -dateByAddingTimeInterval: .

localNotif.fireDate = [now dateByAddingTimeInterval:timeInterval];

---

In Swift 2.2:

localNotif.fireDate = now.dateByAddingTimeInterval(timeInterval)

---

In Swift 3:

localNotif.fireDate = now.addingTimeInterval(timeInterval)
// or simply
localNotif.fireDate = now + timeInterval

Answer 2

try that:

NSDate *date = [NSDate date];     // current date
NSTimeInterval delta = 60 * 1;    // one minute later
if ([date respondsToSelector:@selector(dateByAddingTimeInterval:)]) {
date = [date dateByAddingTimeInterval:delta];
}
else {
   date = [date addTimeInterval:delta];
}
