UISplitViewController使用

阅读更多关于 UISplitViewController使用

分割控制器UISplitViewController <1>功能：它也是ipad的一个新特性，在屏幕上可以同时显示两个控制器，左边一个，右边一个；左边的为主控制器，右边的为详细控制器，主控制器可以根据需要显示或隐藏。它对于iPhone虽然可以使用，但是不具备同时显示的特点，在iPhone的样式，就是导航控制器切换的模式。 <2>介绍 Split View通常只是一个基本元素，它填满整个屏幕，不可能把Split View放到其他什么的内部，一般情况下是提供给整个app的。 Split View有两个ViewControllers，一个左侧一个右侧，左侧叫Master，右侧叫Detail。 SplitViewController有一个property叫做ViewControllers，它是一个数组，这个数组有两个元素，左侧和右侧，左侧是元素0，右侧是元素1 @property (nonatomic, copy) NSArray *viewControllers; <3>代理方法：Split View不能没有delegate，如果没有设置delegate，那么当Split View进入Portrait模式的时候左侧就会消失，你应该在角落里放一个小按钮，使用户可以点击它来让左侧出现 - (BOOL)splitViewController:(UISplitViewController *

Nscell Size Not Increasing With Row Height During Text Edit

阅读更多关于 Nscell Size Not Increasing With Row Height During Text Edit

问题 My NSTableView has variable height rows. The rows correctly resize after an edit of a cell has been completed, and during/after resizing the column/table. The Row also correctly resizes while a user is typing into the text cell. However, the cell itself does NOT resize during editing to match the height of the row. Does anyone have any ideas on this? In this screenshot one end-edit has occurred already (which is why the text area is larger than 1 line) but there is currently enough text in

问题 I have in Matlab a cell named: elem [36 29] [] [30 29] [30 18] [] [31 29] [] [] [8 9] [32 30] and a matrix named: conn 1 2 1 3 1 4 1 5 2 3 2 4 2 5 3 4 3 5 4 5 and i want to make 2 new matrices which will contain only the elements that correspond to non-empty cells of elem without using a for loop. For example the correct result would be: 29 36 29 30 18 30 29 31 8 9 30 32 and: 1 2 1 4 1 5 2 4 3 5 4 5 Any help would be greatly appreciated. 回答1: inds = ~cellfun('isempty', elem); %// NOTE: faster

How to insert, through VBA, a formula in a cell with special characters like “-” or “$”?

阅读更多关于 How to insert, through VBA, a formula in a cell with special characters like “-” or “$”?

问题 I searched on internet, without any help coming out of that... I simply would like to be able to have my VBA code to write this formula in a cell : =IF(C4="-"; "-"; Cars!C4*C4*Data!$C$8) As you guessed, there is a page called "Cars" and one called "Data" where I pick the informations needed. Of course, as it is a VBA code, the C4 will be 2 variables, one for the C and one for the 4 that will evolve... Actually, I tried this : Worksheets("Calculation").Range(Column & PosStartCalc + 1).Formula

Replicate elements from an array into a different array in Matlab

阅读更多关于 Replicate elements from an array into a different array in Matlab

问题 In Matlab I have an array "latencies" (size 1x11) and a cell array "Latencies_ms" (size 1x298). latencies is a smaller part of Latencies_ms , i.e. the values in latencies exist within Latencies_ms . I want to be able to find each value in latencies inside Latencies_ms and then add 1000 to that value and repeat this 8 times inside Latencies_ms . So for example, latencies = [62626 176578 284690 397708 503278 614724 722466] and (a small sample of Latencies_ms) Latencies_ms = {3458, 62626, 123456
