Hello, In my app, I have a UIImagePickerController. When a image is selected, my view controller needs to get the image and pass it to another view controller, which is pushed onto self.navigationController. But I am always getting SEGFAULTS or nil arguments, and things like that. I would appreciate it if you could tell me what is wrong ...

I'm not sure what the iPhone version of this is called but in HTML it is an image map. Certain areas of the map route you to different pages. I'd like to use an image, mostly in a scrollview, that I can have certain areas perform different actions. For example, Chemical Touch, http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoft...
Hi, I'm using UIImage to render a game map from 32x32 blocks. The code is as follows for( int x = 0; x < rwidth; ++x) { for(int y = 0; y < rheight; ++y) { int bindex = [current_map GetTileIndex:x :y]; CGPoint p; p.x = x * tile_size_x; p.y = y * tile_size_x; [img_list[bindex] drawAtPoint:p]; } } This ends up rendering abo...
I'm getting the UIImage from the image picker and putting it into a UIImageView. It works fine for regular images, but for images taken with the iphone camera, they sometimes come up rotated 90 degrees.

I am grabbing an image from the camera roll and then using it for a while as well as save it to disk as a PNG on the iPhone. I am getting the odd crash, presumably due to out of memory. Does it make a difference if I save it as PNG or JPG (assuming I choose note to degrade the quality in the JPG case)? Specifically: is more memory t...
I'm attempting to add a black overlay over some current UIImage's (which are white). I've been trying to use: [[UIColor blackColor] set]; [image drawAtPoint:CGPointMake(0, 0) blendMode:kCGBlendModeOverlay alpha:1.0]; But it's not working, and I'm pretty sure set isn't supposed to be there. ...

Hi, I am currently working on an iPhone game, and need to create some animation on the fly. The animation is based on several images, and as the range of image combinations is too large and it is impossible to pre-create all of sequences, I'd like to be able to recalculate a set of images every time the situation changes. The function ...
I'm getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll. In the UIImagePickerControllerDelegate callback method, the UIImage.imageOrientation comes up as UIImageOrientationRight no matter how the photo is taken. When reading it off the Camera Ro...

I created a plist that contains an NSDictionary structure. The key is a label (which I use to populate tableview cell.text) and the value is a file name that I want to use to 'dynamically' populate cell.image.
