当我移植使用SpriteKit到iPad的iPhone应用程序时,我已经能够使用iPhone 5到iPad屏幕的高度比来缩放所有屏幕元素和字体大小.
一切都看起来是成比例的,除了物理,因为有更多的区域.
所以问题是,如何使用该高度比率将物理学与屏幕一起缩放？
也许改变所有节点的密度或质量？我怎么做,数学上使用比率,这是完美的？
我收到此错误:
#1054 - 'on子句'中的未知列'examineresults.userid'
我已经看过其他帖子,但我似乎无法弄明白.我不认为我指的是任何乱序......
SELECT examinationresults.id AS id, examinationresults.examid AS examid,
examination.tag AS examtag, examination.title AS examtitle, examinationresults.revision AS revision,
examination.medicalspecialtyid AS medicalspecialtyid, medicalspecialties.title AS medicalspecialtytitle,
examination.institutionid AS institutionid, institutions.title AS institutiontitle,

FROM examinationresults, examination
INNER JOIN medicalspecialties
ON examination.medicalspecialtyid=medicalspecialties.id
INNER JOIN institutions …我使用以下.htaccess代码:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ca/(.+)$ /index.php?p=$1&c=ca [L,QSA]
RewriteRule ^fr/(.+)$ /index.php?p=$1&c=fr [L,QSA]
RewriteRule ^(.+)$ /index.php?p=$1 [L,QSA]
为了达到以下效果:
http://xyz.com/ca/test -> http://xyz.com/index.php?p=test&c=ca
http://xyz.com/fr/test -> http://xyz.com/index.php?p=test&c=fr
http://xyz.com/test -> http://xyz.com/index.php?p=test
但它失败了服务器错误.关于如何修复它的任何想法？
谢谢
我正在尝试获取XPC流程的负责流程的PID.
例如,Safari的PID为500,并与3个com.apple.WebKit.WebContent.xpc实例进行通信,PID为510,520和530.
Activity Monitor.app似乎知道这3个XPC进程与Safari有关.它声称"进程组"是"Safari Web Content".
但这与真正的unix进程组ID无关.GPID不是Safari.app的.实际上,Safari.app甚至不是进程父进程 - launchd是.
所以问题是 - 如何知道com.apple.WebKit.WebContent.xpc实例的"负责"PID(即Safari或Mail)？
