Custom UIScrollView Animation

由 你说的曾经没有我的故事 提交于 2019-12-12 09:51:47
问题 I am using a UIScrollView with a list of buttons made to look much like a UIPickerView. I have just implemented shake to shuffle, where upon detection of a shake I set the content offset of the UIScrollView to the position of the randomShuffle using the following. [Singlescroll setContentOffset:CGPointMake(jumpX, jumpY+randShuffle*sepValue) animated:YES]; Instead of just moving the content offset to the random position that matches a button I would like to implement a shuffle animation where

Reposition drop down menu if near edge of window

由 帅比萌擦擦* 提交于 2019-12-12 08:58:27
问题 I'm using the following code to reposition my drop down menus if they fall outside of the browser window area. However it does not work in Internet Explorer 7 and 8. jQuery(document).ready(function(){ jQuery("#nav>ul>li").each(function() { pos = jQuery(this).offset(); if(pos.left + 100 > jQuery(window).width()+window.pageXOffset-jQuery(this).width()) { jQuery(this).addClass("nav-shift");} }); }); 回答1: The window.pageXOffset property is not supported in IE (7 and 8, at least). Try $(window)

Non integer offset positions in jQuery

由 蓝咒 提交于 2019-12-12 08:39:52
问题 jQuerys offset function sometimes returns rational numbers (like 12.645613) for top or left. I thought that top and left positions are in pixels and so should be integers (there are no half pixel, or?). 回答1: Top and left positions can be floating point numbers with any of the units cm, mm, in, pt, pc, em, ex or px, or percentages. Example: .someElement { top: 42%; left: 3.14in; } The offset function returns the position translated into pixels, so that can very well be a floating point number.

Selecting a Specific Column of a Named Range for the SUMIF Function

由 本秂侑毒 提交于 2019-12-12 08:28:31
问题 I am trying to create a SUMIF function that dynamically adds up values in a specific column of a named range in my Excel sheet. It is very easy to do this when there is no named range : The formula picks out all the cells that contain "London" in their name and sums up the expenses related to London. What I am trying to do is to use a named range called TripsData (A2:B5) and tell the SUMIF function to sum the entries in the column 2 of this range that meet the criterion of having London in

would there be such case of jumping, if yes how?

由 一世执手 提交于 2019-12-12 05:38:14
问题 I have an issue in the mind and that is since the jump instruction changes EIP register by adding signed offsets to it(if I'm not making a mistake here), on IA-32 architecture how would going upward in memory from location 0x7FFFFFFF(biggest positive number in signed logic) to 0x80000000(least negative number in signed logic) be possible? or maybe there shouldn't be such jump due to the nature of signed logic? 回答1: Signed and unsigned are just two ways of interpreting the same bit pattern.

VBA copy-paste offset to another workbook

由 断了今生、忘了曾经 提交于 2019-12-12 05:14:54
问题 I would need your advice if you could help me because my VBA knowledge is very poor. I have 4 columns and thousands of rows, I would like that first row to be copied-pasted transposed in another workbook by hitting a command button, after that the second hit of button to overwrite the previous copy-paste and so on (in the second workbook I have some formulas which are gonna apply to the new values and I have to check the results). Many thanks in advance! Here is the code that I have done it

How to WriteProcessMemory with multipointers

由 风格不统一 提交于 2019-12-12 04:53:12
问题 First of all, what I am trying to do is changing a value in the memory of a game. In order to write to that variable I need to add the following pointer and offsets because then I always get to an address that works: baseAddr + offset1 + offset2 + offset3 = myDesiredAddr Now, this is what I have tried to do... ReadProcessMemory( hProc, (LPVOID)(BaseAddr + offset1), &myDesiredAddr, sizeof(myDesiredAddr), 0 ); ReadProcessMemory( hProc, (LPVOID)(myDesiredAddr + offset2), &myDesiredAddr, sizeof

How to insert an offset to hexdump with xxd?

由 岁酱吖の 提交于 2019-12-12 03:15:59
问题 Is there an easy way to add an offset to the hex dump generated by xxd ? i.e instead of 0000: <data> 0004: <data> 0008: <data> I should get Offset+0000: <data> Offset+0004: <data> Offset+0008: <data> 回答1: This is what I am doing now..It works perfectly but its kind of lame approach for just adding an offset :) xxd file.bin | xxd -r -s 0x2e00000 | xxd -s 0x2e00000 > file.hex 回答2: xxd now appears to come with offset support, using -o [offset] for example: xxd -o 0x07d20000 file.bin My version

Stop changing offset on hover jQuery

由 本秂侑毒 提交于 2019-12-12 02:12:53
问题 I would like to create a small bar in the left side of the browser window which tracks the mouse Y-position and follows the mouse. So far, no problems. But now I would like to stop the the div from offsetting when the mouse is hovered over the div to make it also possible to click on the content the div just revealed. I've made a fiddle to make myself clear http://jsfiddle.net/UXWp6/ <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script

Offset is outside the bounds of the DataView;at api notifyBLECharacteristicValueChanged success call

由 人盡茶涼 提交于 2019-12-11 22:45:19
在做微信小程序开发，向蓝牙发送信息时，遇到这样一个错误 错误解释： 数组下标越界 报错原因： 我在设置ArrayBuffer时，直接设置过少，导致在循环通过蓝牙传递信息时，造成数组下标越界。 解决办法： 方法一 ，给ArrayBuffer长度设置更长； 方法二，在循环时，获取数组的长度，确保数组长度不超过循环次数。 修改后代码： var retstring = [1,2,3]; var buffer = new ArrayBuffer(14); //设置最多保存14个字节 var dataView = new DataView(buffer); let values = 0; for (let i = 0; i < retstring .length; i++) { let str = retstring[i] + ""; if (str.length>=2){ values = str.charCodeAt();//字符转为ascii } dataView.setUint8(i, values);//向蓝牙发送命令参数 } 详细报错信息： Offset is outside the bounds of the DataView;at api notifyBLECharacteristicValueChanged success callback function
