iOS - 跳到系統App內部設置

從App中跳轉到手機設置中此App內的設置授權界面：

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
 if ([[UIApplication sharedApplication] canOpenURL:url]) {
     [[UIApplication sharedApplication] openURL:url];
 }

轉自：這里

在iOS應用程序中打開設備設置界面及其中某指定的選項界面

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Restrictions"]];
一些其他可用的參數:

太懶了，不想翻譯，自己看吧，有時間了再處理。
