问题 iOS Notes and Mail apps have a three-pane split view interface on iPad landscape mode. How can I create such interface?

问题 I want to create a toolbar without using the UIToolbar, instead I used image views and UIButtons but when I change the orientation of my iPad they remain where they are positioned. Why didn't I use UIToolbar? Because I am having problems with the spacing of my buttons, because I want them closer to each other but on UIToolbar the space are wide.

When I built the bundle, I targeted iOS 3, so that people running older iPhones (like my wife who has iPhone 3 with iOS 3.x on it) can run the application. The app was also tested on, and runs fine with, the latest 4.x iOS. With the release of iOS 5, I want to make sure my app is compatible. There is

问题 I have a UIScrollView that contains a UIToolbar, but when I scroll, the toolbar scrolls as well, separating from the bottom of the screen. Is there a way to make the toolbar stick to the bottom of the screen as the scroll happens? I tried to create a view that contained both the ScrollView and the Toolbar, but when the program runs, the ScrollView is all that I can see. This problem could be due to the ScrollView being drawn on top of the toolbar, but I'm not sure. Any help in either of these

问题 environment: creating an iPad application using Monotouch and the Monotouch.Dialog library. I've been trying to set the background color on a DialogViewController to no avail. I have multiple views in my application being loaded an unloaded. For non of them I manage to set the background color.

问题 I keep getting a warning that my ipad launch image landscape isnt 1024x748, while it actually is that size. When i do compile with the 'wrong' size, it gives me a bloated portrait image. 回答1: If you're on Xcode 4.0.2+ then the landscape iPad launch image needs to be 748 * 1024. This is how it works in one of my apps. Good luck! 回答2: @MaikelS - What version of Xcode are you using? In Xcode 4.0 on Snow Leopard my landscape launch image would throw a warning even though it would load in the app
