Question

Is there a method to store the state of a UISwitch with NSUserDefaults?
If the state is ON I d like to set some action...

Can I do this?
Thanks!

Answer 1

热帕韦2的答案是好的,也能很好地促进大片部分控制(超过2个州)。但是,如果你只想储存2个州,那么为什么不只使用<条码>。

    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
   [userDefaults setBool:switchState forKey:@"mySwitchValueKey"];

并公布:

   BOOL swichState = [userDefaults boolForKey:@"mySwitchValueKey"];

仇恨更简单,甚至根本不成规律,不扼制反向和改换。

储蓄:

- (void)mySwitchAction:(id)sender
{
  if (sender == mySwitch) {
    BOOL mySwitchValue = [ sender isOn ];
    NSString *tmpString = mySwitchValue ? @"1" : @"-1" ;
    NSUserDefaults  *myNSUD = [NSUserDefaults standardUserDefaults];
    [ myNSUD setObject:tmpString forKey: @"mySwitchValueKey" ];
    [ myNSUD synchronize ];
    // do other stuff/actions
  }
}

从挽救的国家开始:

NSUserDefaults  *myNSUD = [NSUserDefaults standardUserDefaults];
NSString *tmpString =  [ myNSUD stringForKey: @"mySwitchValueKey"];
BOOL mySwitchValue = NO;  // or DEFAULT_VALUE
if (tmpString != nil) { 
  mySwitchValue = ( [ tmpString intValue ] == 1 ); 
}
[mySwitch setOn: mySwitchValue];
