I'm developing an app and one of its features is similar to twitter,so I have a table with each "tweet" and I display the user's picture too and I don't know what is the best way to load a lot of pictures. The images come from the server as an url.
My app's structure is:
1- I call to the server, and I get the response
2- I parse the response and I iterate it creating objects
3- I load that objects in the tableview's store
4- I reload the table
I thought one way is when I am creating the object, I load the image and I assign to the object's attribute. I mean, each time I create a object type "tweet" for example, I create the image calling the url with nsdata...
I dont know if that solution is correct or can be better. Can anyone give me a hand? Thanks in advance
Take a look at the SDWebImage API. It will do much of this automatically for you.

I'm developing an app that I want the user to be able to take a screenshot with a button (this works, but it's stored to camera roll). I have a need to keep history of these screenshots along with site name, etc.
I've been reading that it's not recommended to save binary data in a sqlite db, so I've stumbled across core data. I'm still learning, but one question that comes to mind is this. Some recommend to save the filename to coredata and then save the image to document directory. I want to read the data back into a table view controller and have the image part of the cell. Will I need to resize the image to the size I want when reading in, or will it automatically size down to what it needs?
Also, when saving to document directory, are those files accessible from the camera roll? I don't want them to be and I'd like to give the user the ability to be able to delete them with the tableviewcontroller.
Please let me know if I need to expand on anything. I'm learning Swift, so I'm sure I missed something.
You should not save it to the Documents directory.
You should instead Allow External Storage of the attribute. Core Data will take care of storing it for you. This is explained in the answer by jansenmaarten to this question.
I am making a app in which I am retrieving data from Database in List View.
I want to have different picture with each data I retrieve from database in list View.
What I am trying to do is to save my pictures in drawable folder of my app and want to save image path in database and retrieve my image from saved path.
I searched lot on internet but couldn't get appropriate solution.
Somebody please show me appropriate code.
Don't know if you already have solved this problem,
but after looking for it myself i found a solution.
what i did was use this.
i stored my images in a subfolder in "Assets" and this works like a charm,
don't know how many images it can hold in total, but i'll find out eventually i guess xD
I need to load a website in a cocos 2d game.
For example,when a ccmenu button is clicked,i need to replace a scene where it must load an particular website.
Any ideas please,thanks.
It sounds like you want to get game data from a server, correct? In that case, you probably aren't going to want to load an HTML page. Instead, come up with some a method of storing pertinent game data in a more appropriate file format. I can't say for sure because I don't know anything about your game, but saving your game data as XML might work well. Then, when you need to update the game with data from your sever, use an NSURLRequest or similar to download the XML file, which you can then parse as you see fit.
Look into CCHttpRequest or CCHttpClient.
Recently i am making an app on facebook. So i have use facebook api. From api we got data from json parsing. Now in my app i am showing all update of user and his friends in table view. But problem is that when i get data from json parsing then application take so much time due to loading image in app. So i want that i show first text message and when view did load then upload images so that time will reduce. How do that i have no idea? So tell how i fix it?
I have use synchronous method to parse data from json. What approach i will use so i can consume less time?

First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app!
Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score.
Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML?
Or an even better question, is there a better way?
Thanks in advance for any and all help!

This is what UITableView was made for. Read your plist into an array and feed the contents to the table view through its datasource/delegate methods.
