更改按钮标签作为开关关闭声音，我想显示一个开关（对象，切换）

Question

我想用开关更改按钮。我需要改变什么？  我想显示一个开关（xcode中的对象，切换）

- (void)doButtonSounds:(id)sender
{
    [SoundUtils sharedInstance].soundOn = ![SoundUtils sharedInstance].soundOn;

    [Flurry logEvent:@"SETTINGS: doButtonSounds"
      withParameters:[NSDictionary dictionaryWithObjectsAndKeys:@"SoundOn", [NSNumber numberWithBool:[SoundUtils sharedInstance].soundOn], nil]];

    [self refreshView];
}

Answer 1

在doButtonSounds中添加以下行：

UIButton* currentButton = (UIButton*) sender; // You won't need this probably.

NSString* newText = [SoundUtils sharedInstance].soundOn ? @"ON" : @"OFF";

[currentButton setTitle:newText forState:UIControlStateNormal];
