IOS如何跳转系统设置

因为某些业务需要 app需要调到系统设置页面:

• 方法一
  NSURL *url = [NSURLURLWithString:UIApplicationOpenSettingsURLString];
  if ([[UIApplicationsharedApplication] canOpenURL:url]) {
  //如果点击打开的话，需要记录当前的状态，从设置回到应用的时候会用到
  [[UIApplicationsharedApplication] openURL:url];
  }

• 方法二

  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]]
