Cannot setBool NSUserDefaults

Question

I'm trying to set userDefaults, but it isn't working. Have anyone else experience this problem? Tried both on simulator and device. Xcode 6.3.1 and iOS 8.3

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:YES forKey:@"active"];
BOOL active = [defaults boolForKey:@"active"]; // RETURN NO

Answer 1

谢谢这段代码： 你错过了同步nsuserdefault。

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:YES forKey:@"active"];
[defaults synchronize];
BOOL active = [defaults boolForKey:@"active"];
