iOS5的SDK现在可以直接打开setting页面了，以往的SDK则不可以
补充一点，下面的方法是undocument的，所以可能会被reject.
如果你想打开Location Services的setting页面，代码如下：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];

如果想打开Twitter的设置：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]];

如果想打开蓝牙的设置：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Bluetooth"]];

当然你还可以打开应用的设置：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Apps&path=Your+App+Display+Name"]];
