I want to know is this a IKImageBrowserView object? And How can I add an NSProgressIndicator when loading the image?
It certainly looks like it could be one. How you add a progress indicator depends entirely on how you download the image. If you are using NSURLConnection then you can get status updates through connection:didReceiveResponse: and connection:didReceiveData:. The response structure contains the expected length of the file, which you would use as the maximum of your progress indicator, and the data contains the length of the data that you recieved in that chunk. Add that length to the lengths of the previous chunks you get will give you how much data you have received so far. That would be the position on your progress indicator.
I think it is not IKImageBrowserView.It is a NSCollectionView.I also faced this problem then I googled and searched in internet to add NSProgressIndicator in IKImageBrowserView I did not get any solution. Finally I found NSCollectionView is the way to add NSProgressIndicator animation when images loading.So I moved to NSCollectionView. click here to more details.

By default, in a NSTextView, image attachments are displayed at their actual resolution. For large images, this results in having only a small portion of the image displayed in the view. This doesn't look good and the user has to do lots of scrolling to enter text after the image.
For example, in the window below, you can't tell much about the image in the text view.
So the question is: how to scale down image attachments, so that they fit in the NSTextView?
You can find a few solutions for this on the internet, based on subclassing NSTextAttachmentCell, but by doing so, you lose a number of good behaviors provided for free by the NSTextView, like the creation of annotations in an attached image.
Actually there is a much simpler solution: to use a NSLayoutManager property named defaultAttachmentScaling that does exactly what we want.
In your code, set this property as in:
myTextView.layoutManager.defaultAttachmentScaling = NSImageScaleProportionallyDown;
and this is it: large images are now scaled to match the width of the text view.
For detailed information on this property, I suggest you read the comments in the header file NSLayoutManager.h.
Note for iOS developers: unfortunately, this property is not available on iOS.
Note: I looked at the other questions similar to this one, and they were either outdated or not useful.
Unfortunately there are so many different screen sizes and that makes auto layout really confusing for me. I want to have a simple UIImageView to cover the entire screen no matter what screen size it is. So the dimensions of the UIImageView should change accordingly.
I tried adding constraints to squish the image and it worked fine. But an error in the debugger said that there was an error: UIViewAlertForUnsatisfiableConstraints
Is this a big deal? And if it is, how do I get the Image to fill the entire screen?
Edit: The game will have squares going down the screen, which the user must tap
It might be, or it might not be a big deal, depending on what you're doing and if you know what you're trying to accomplish. In my experience, this is usually an issue if you're trying to programmatically alter the frame of a view which already has set constraints (you shouldn't alter the frame by hand unless you really need it).
Without more detail, it's hard to say what the exact issue is.
I am asking about a wp7 control, which presents an image. I don't know how to do this, and havn't found this in internet. So i need a control, which has different datatemplate depending on count of images needed to present.
So, if we need present one image - it will fully show it on full control's size.
If there are 2, 3 or 4 images - they must look like in a grid. So their size = size of control / 4.
Examples:
ImageSource has only one Image Item
ImageSource has four Image Items
Thanks for advices.
I thought to create usercontrol wich is inherit from ListBox, but i don't know how to realize the question.
You should write custom panel, this will be the best way for you. Custom panel will give you speed and flexibility, and implementing it takes 1-2 hours.
See example here: http://blogs.msdn.com/b/silverlight_sdk/archive/2008/04/03/creating-a-custom-panel.aspx
A wrappanel should work, check the wp7 toolkit on codeplex, it contains such control.
If you add all the images to that control and set there "Stretch" property to "Fill", I assume it should work.
untested
Previous failed, as far as I know, you'll have to write something yourself. I haven't encountered such control yet.
I'm trying to create a news viewer with Xcode 4. This should look like the following:
===============================
Title comes here ------- Date
Image
News Body
================================
As you can see, the news body must be pushed downward depending on the size of the image. The image must be pushed downward as the height of the title varies. I know I have to do some programming to position them dynamically. The only problem is I'm not familiar with CGRect and Frame things...
Where can I find a tutorial or sample code I can take a look and get some ideas? Practical codes or tutorials would be appreciated as just reading documentation doesn't really give me a clear idea how to approach this.
UILabel provides -sizeWithFont:constrainedToSize:lineBreakMode: which will allow you to determine the size needed to fit the text you wish to display. I put together an example of resizing UILabels when I first ran into a similar problem and posted it here: http://blog.carbonfive.com/2009/07/10/resizing-uilabel-to-fit-text/
I'm afraid that's rather old now but I think should still be of some use.
I'm using the TTTableViewController and datasource and I notice every time a new cell is being loaded it is a little bit sticky. My source code is too long to post so I was wondering if there were any tips or things to look out for to optimize the three20 table view?
This is very interesting. I have a tableView that creates many UIImageViews in lazy loaded cells and replacing imageWithContentsOfFile virtually removed a slight pause when the cells were being recreated. Each cell has 1 changing image, and 2-3 images that never change.
According to this thread, imageNamed should not be used: img_data_lock iphone - imageNamed vs imageWithContentsofFile, I have not noticed any crashes with imageNamed, can you explain why this is so?
