Hi In my iPhone app, I have a number of UIImageView that do the same thing, then a second load which do the same thing. Can I some how tag/group these so that I can simply reference all the objects with one name? Otherwise it means having to have dozens of lines of code for a single repetitive action. Thanks! ...
Hi I want to rotate a uiimageview by roughly 10 degrees left/right but have a smooth animation, rather than a sudden turn which I see using: player.transform = CGAffineTransformMakeRotation(angle); Any help appreciated, thanks. ...
I have a collection of images that the number of them aren't determined and vary from 0 to 1000, anyone got an idea how can I present them to the user? I think I can add each three of them to a uitableviewcell but I don't know how. any help would greatly appreciated. :) ...

Hello, I'm programming a few picture viewers for the iPad and the problem that I always have is that unless you use a really big resolution image source, when the user zooms, the image will get pixelated. I was thinking that maybe some kind of upscaling filter could be applied to the image when zoomed. Like the ones here http://en.wiki...
I've just started iPhone development, and have come across an annoying problem. I am transitioning from one view to another, however in the interim I'd like to display a loading image. The controller currently contains a TableView and TabControl. I have added an image and label to the control (of a 'loading' image) and linked them up to...
I have a uiimage in a uiimageview. the uiimage doesn't fill the entire uiimageview. I'm trying to have a border with rounded corners, but just around the uiimage, not the entire uiimageview. Can't figure out how to get it. I have homeButtonImage.layer.cornerRadius = 5; homeButtonImage.layer.masksToBounds = YES; homeButtonImage.laye...
I have a UIImageView that has a UIImage (obviously), and I want to get the dimensions of the UIImage so that I can draw a border with rounded edges for just the UIImage (not the entire UIImageView). Thanks. ...
I have an image displayed using CGRect (code below). the problem is that it's obscuring UIButtons I have in the nib file. CGRect myImageRect = CGRectMake(0.0f, 40.0f, 480.0f, 280.0f); UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect]; [myImage setImage:[UIImage imageNamed:recipe.image]]; [self.view addSubview:myIma...

I have a UIImageView that I have already set an image to. This works fine, but later, I want to change that image. So, I set a new image for the image property, but when I view the app, that image is set as a second image over the first: UIImageView *image; image = (UIImageView *)[cell viewWithTag:0]; image.image = [UIImage imageNamed...

All images is in the size 1024x748 (iPad landscape resolution with status bar) and...
I have a UIImageView displaying a picture that I took with the iPhone Camera. On top of that, I have a UITextView in which the user can type stuff that describes the picture. I would like to create a combined image of the two views and send it to a server. Anyone knows how I can do that (just creating the image. I know how to send it)...
Hi Guys! I have a problem with NSNumber: I don't understand how to increment and decrement it! I've tried int with [NSNumber intValue] and so on, but it didn't work!!!! I just want a page counter which can be converted to an NSNumber at the end. My second problem is displaying a (partially) transparent image in an UIImageView. It has e...
Hi, I have a variable sized array of UIImageViews that I'd like to add to my main View. So I loop through the array, adding each UIImageView to the scene as follows: for (UIImageView *nextImageView in myImageArray] [self.view addSubview:nextImageView]; (I also configure their frames individually but have left that out here) Howev...

While switching between modes I am getting EXEC_BAD_ACCESS error randomly. Randomly means I can switch to Actual Size mode to Fit to Screen modes copule of ...
Hi there... Is there any way to display an image infront of the navigation bar? I know this is a little bit messy - but its just an asthetic thing. The imageview takes up more height than the view and therefore needs to overlap the navigation bar a little bit. Is this possible at all? It must be. :) Thank you ...
I'm designing a progress bar for an app that essentially is two UIImages - both are the exact same size (long rectangles with rounded corners), except they are colored differently. The bottom bar is black and the progress bar that will fill over it is grey. Displaying the bottom bar is easy enough. The issue I'm trying to figure out is...
I'm trying to instigate a page curl transition with a UIImageView in a Window.
