Answer 1

试试这个

if ([[[UIDevice currentDevice] systemVersion] floatValue] < 8.0) { 

} else { 
    //iOS 8 specific code here 
    [self openSettings]; 
} 


- (void)openSettings 
{ 
    BOOL canOpenSettings = (&UIApplicationOpenSettingsURLString != NULL); 
    if (canOpenSettings) { 


     NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString]; 
     [[UIApplication sharedApplication] openURL:url]; 
    } 
}

@IBAction func settingsApp(sender: UIButton) { 
    let appSettings = NSURL(string: UIApplicationOpenSettingsURLString) 
    if let gotoUrl = appSettings { 
     UIApplication.sharedApplication().openURL(gotoUrl) 
    } 
}
