NSUserDefaults的使用
?
1.保存对象string:
NSString *string = [NSString stringWithFormat:@"string"];?
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:string?forKey:[NSStringstringWithFormat:@"key"];
[userDefaults synchronize];
?
? ? 取出对象:
? NSUserDefaults?*userDefaults = [NSUserDefaults?standardUserDefaults];
??NSString *value = [userDefaults objectForKey:@"key"];
?
我经常用来保存个对象,在另外一个类中取出,用来判断, 关键用通知传值老是接收不到通知,就用这个来替代,效果还好...有点囧
