I’m busy making a customized table view app and was wondering if it will work with IOS 5.
iOS 5 is what brought in the appearance API's for UIKit Controls

But for table views? Depends on what you are trying to do. If you are dropping controls into a custom cell, then "maybe". :-) Aside from "automatic row animations, moving rows and sections, multiselection, and copy and paste behaviors for cells", UITableView objects & functionality remain fundamentally the same.

i am just developing some simple app which show the periodic table but my problem is how can i achieve the periodic table like layout in my iPhone app in just landscape format.
i have tried to search some CustomGridLayout sdk for IOS but not suitable for me
have goggled the things but not succeeded
following is the reference of periodic table layout which i want to implement
There is a couple way to do this:
1) You may use UICollectionView with custom cell. for this.With cell size equal element cell. But you will hit a several problem here: Some cells should be disabled, and customized in non standard way. In this case section is not useful for you. Overlay button in top on collection view may be difficult to positioning in storyboard.
2) You can use UIContainerView with totally custom view and colors. Dynamically added to custom row and column. This ofc have some flaws. Harder to build layout in storyboard (compared to (1) solution), memory management issues.
I wanted to know if there is a open source UI library in objective c for grid view like in ted.com or tile.js which is also an open source library for metro style UI used in apps like pulse.me.
Basically I want a grid view with cells of different sizes! I want to make something it on iOS for both iPad and iPhone.
Thanks.
In iOS 6.0 your best choice would be UICollectionView.
UICollectionView is available in Available in iOS 6.0 and later and therefore cannot be used if you want to support earlier version.
And as per your requirement you need to display a GridView
So to support earlier versions and get other cool features you can use other libraries here are some of the options:
1) KKGridView
2) UIGridView
3) AQGridView
4) NRGridView
5) MMGridView
6) WCGridView
I am currently using AQGridView so surely i recommend that as it is the least buggy and its functions are very similar to UITableView.
Also that If you are trying to do this without XIB it will be little bit difficult for you to handle it but you can create a view controller with Xib file to Create the interface of your choice. Here is the Video of how it can be done in the best possible way by Evadne Wu. And here is the Sample Project
I'm an iOS developer looking for a solution to a tricky problem.
I need to create a grid view/ mosaic view to layout cells of different sizes (both width and height).
I basically need the functionality of a GMGridView, with horizontal scrolling/paging, the ability to edit, and drag cells to new locations, thus rearranging the entire grid view. I've looked at all of the current open source grid views out there, and found none with variable sized cells.
One solution I have thought about is 2 tableviews both rotated for the horizontal scrolling, and then intercept some UITableView scrolling methods, to then scroll the other tableview together. This is not ideal, as I will be unable to move a cell from one view to another, and I'm not sure how happy apple will be about it.
I also know of some possible (confidential?) support for this coming in the next version of iOS, but would like to keep my app supporting previous versions of iOS.
Thanks for any insight you can provide.
I realize this post is kind of old, but here is a list of relevant projects: *https://github.com/betzerra/MosaicUI

GridViews on iOS are a pain. Fortunately Apple is coming up with UICollectionViews that are optimized to build grids. This is coming in iOS6 and it's still under NDA so check out the documentation on Apple's website for more information.
The question you need to solve now is whether you want iOS5 retro-compatibility or not
Can someone explain in simple words the difference between .xib and .storyboard?
Apple introduced the concept of "storyboarding" in iOS5 SDK to simplify and better manage screens in your app. You can still use the .xib way of development.
Pre-storyboard, each UIViewController had an associated .xib with it. Storyboard achieves two things:
.storyboard is essentially one single file for all your screens in the app and it shows the flow of the screens. You can add segues/transitions between screens, this way. So, this minimizes the boilerplate code required to manage multiple screens.
Minimizes the overall number of files in an app.
You can avoid using Storyboard while creating a new project by leaving the "Use Storyboard" option unchecked.
You could refer this tutorial to get started.
Yes, you can still create a Window-based application for iOS 5. If you use the "empty project" template, you will see that a window is created for you in the app delegate. From there you can add XIB files as normal, or a new storyboard.
I'm assuming you mean "storyboards" rather than "timeline". Storyboards allow you to map out, visually, all of the views in your applications and how they interrelate. If you are just starting out with storyboards, there's an introduction to storyboards in the WWDC 2011 videos here. The 2011 Stanford iOS course on iTunes-U is also iOS 5-specific and covers storyboards and more.
A storyboard is like a canvas where you put all your .xib files. You no longer have any .xibs, you just have View Controllers directly on your canvas.
storyboard is a new feature available since the release of Xcode 4.2.
It offers a complete new way for iOS developer to create and design
user interface. Before the introduction of Storyboard, it’s especially
hard for beginner to create navigation (and tab) interface. Every
interface is stored in a separate xib file. On top of it, you have to
write code to link all interfaces together and describe how the
navigation works.
With Storyboards, all screens are stored in a single file. This gives
you a conceptual overview of the visual representation for the app and
shows you how the screens are connected. Xcode provides a built-in
editor to layout the Storyboards. You can define the transition (known
as segues) between various screens simply using point and click. This
doesn’t mean you do not need to write code for the user interface. But
Storyboards significantly reduce the amount of code you need to write.

XIB:
Xib files are used with a single UIView.
2)It's very difficult to implement complex auto-layouts in xib.
3)It's utilizes more memory as compared to storyboard and quiet slow.
It is compatible from iOS5 and onwards
You can do localizations for different languages and countries using
different XIBs .
It's difficult to use same Xib to support multiple devices.
Storyboard
1)You can layout all your Scenes like View Controllers, Nav Controllers, TabBar Controllers, etc in a single storyboard.
2)You can use Auto Layout easily that defines mathematical relationships between elements defining their position and sizing.
3)Usually fast and allocates less memory.
4)It's not compatible prior to iOS 5 .
5)"Dynamic" and "Prototype" cells can be used easily.
6)Storyboards best to use for the apps with a small to medium amount of screens.
The best Answer I have seen : Xib Vs Storyboard in iOS
XIB and Storyboard are used for creating interfaces for users.
One important point is,xibs are used for creating a single view(it has single file owner at the top of the xib file), but in-case for viewcontroller, multiple screens can be added and its flow can also be monitored(it has separate file owners).

Hello. I'm diving into iOS development and am building my own alarm app to become familiar with the SDK. My questions are...
I've played around with UITableViews a bit, but I don't understand how I would implement the table at the top half of this form. If I had to guess, I would say it's a single UITableView, defined with one section and four rows, is that right?
If so, to implement it, would I just "hardcode" the cellForRowAtIndexPath function to create each cell manually?
If not, is there an adopted approach to defining the layout and functionality of these types of settings pages?
Row #3 has a switch in it, is this a predefined cell style or a custom cell style that I have to define myself?
Rows #1, 2, and 4 take the user to new views when they're touched. Is this a predefined style and or do I just implement the standard didSelectRowAtIndexPath functionality to push a new view onto the stack?
Thanks so much in advance for your help! I'm going to continue researching these questions right now.
In answer to your questions:
Yes
Yes
n/a
No, you have to add a UISwitch to the cell's contentView. Tip: Look at Apple's UICatalog sample code (controls sections) to see how to implement a tableview with different controls in different rows.
Just use didSelectRow...
For most apps, you want to implement the Application Preferences settings plist that will be used by the device's Settings application. It's typically a good idea to keep the settings for your app consistent with how the settings work in other apps.
