iOS5開啟系統setting頁面

iOS5的SDK現在可以直接開啟setting頁面了，以往的SDK則不可以，當時我還花了大量時間去實現，結果不了了之。

補充一點，下面的方法是undocument的，所以可能會被reject.

如果你想開啟Location Services的setting頁面，代碼如下：

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

如果想開啟Twitter的設定：

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

如果想開啟藍芽的設定：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Bluetooth"]];

當然你還可以開啟應用的設定：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Apps&path=Your+App+Display+Name"]];

Your+App+Display+Name是什麼，你應懂的。 不過我試這個的時候沒有開啟應用的setting,反而開啟的是系統setting頁，不知道為何。
