ios 判斷用戶是否開啟權限---并跳轉“系統設置”
1.判斷 訪問相冊 或 相機 權限是否開啟
2.檢測是否開啟定位
后面將持續更新
只有在應用請求過位置權限 或者 通知權限的時候，才會跳進自己app里面的設置呢。不然直接跳到系統設置界面
//打開app定位設置
NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if([[UIApplication sharedApplication] canOpenURL:settingsURL]) {
[[UIApplication sharedApplication] openURL:settingsURL];
}

===PHAuthorizationStatus===相冊權限狀態判斷
在8.0系統以后，新加入了Photos.framework框架，我們可以利用框架中的PHAuthorizationStatus進行相冊權限狀態判斷。
