有時候我們需要開啟藍芽來連結裝置，像是Beacon、Apple Watch或小米手環。那麼如果使用者沒有打開權限怎麼辦？請他/她到設定藍芽 (Setting Bluetooth)去打開囉～
目前iOS SDK尚未有API可以直接改藍芽設定，要是未來Apple有開放的話請再跟我說唷！不過我想應該要等到天荒地老，非常重視用戶隱私的Apple，是不會輕易讓開發者悄悄開啟Bluetooth來進行任何動作。
剛好我們偉大的技術長有無私分享：

{
NSURL *bluetoothURLOS8 = [NSURL URLWithString:@"prefs:root=General&path=Bluetooth"];
NSURL *bluetoothURLOS9 = [NSURL URLWithString:@"prefs:root=Bluetooth"];
NSURL *bluetoothURLOS10 = [NSURL URLWithString:@"App-Prefs:root=Bluetooth"];
if ([[[UIDevice currentDevice] systemVersion] intValue] >= 10) {
[[UIApplication sharedApplication] openURL:bluetoothURLOS10];
}
else if ([[[UIDevice currentDevice] systemVersion] intValue] >= 9) {
[[UIApplication sharedApplication] openURL:bluetoothURLOS9];
}
else {
[[UIApplication sharedApplication] openURL:bluetoothURLOS8];
}
}
這種沒啥邏輯純粹定義的玩意兒，抄，就對了ＸＤ～
