uiimageview

This is really a n00b question, I am learning iOS while trying to build an app I need to show an image, label on UITableViewCell . The following code does that for me - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; cell.imageView.image = [self getImageNameForRow:indexPath.row]; cell.textLabel.text = self.features[(NSUInteger) indexPath.row]; cell.imageView.contentMode = UIViewContentModeScaleAspectFit; return cell; } The problem

Hi i am new to iphone.. I have stored the images in array .I want to know how to display those images in UIImageView ,where the UIImageView should be created dynamically according to filelist count increases, in for loop. this is the code NSArray *filelist; NSFileManager *filemgr; int count; int i=0; int t=0; filemgr = [NSFileManager defaultManager]; filelist = [filemgr directoryContentsAtPath: @"/Mypath/"]; NSMutableArray *imageVwArr = [[NSMutableArray alloc]init]; count = [filelist count]; count++; for(i = 0; i < count; i++) { UIImageView *imgVw = [[UIImageView alloc] initWithImage:[filelist

I have a db where items are stored. These items can be different kinds of type like text, videos and images. When the View is loaded I fetch these items from the DB and I show them in a UITableView. The problem I am facing is related to show the images in the table view. Basically in the DB I store the ALAsset link related to the picture and from it I try to get its image using this code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ //...Other Code else if ([object isMemberOfClass:[Picture class]]){ //Get a reusable cell cell =

I have one UIImageView having an image of an arrow. When user taps on the UIView this arrow should point to the direction of the tap maintaing its position it should just change the transform. I have implemented following code. But it not working as expected. I have added a screenshot. In this screenshot when i touch the point upper left the arrow direction should be as shown.But it is not happening so. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch=[[event allTouches]anyObject]; touchedPoint= [touch locationInView:touch.view]; imageViews.transform =

i capture the image using image picker, at the that time image is in its actual position. but after uploading it on server it became horizontal. i don't get any clue why that happening. here is my code NSString *urlString = @"Url"; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; NSMutableData *body = [NSMutableData data]; NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; NSString *contentType = [NSString stringWithFormat

What I've been trying to achieve for a couple of hours is something like the following: I would like to have a UIImage in the background and then preferably a UIView with a background color of red with some kind of multiply effect (the red area). Is this possible? I've seen a few extensions for UIImage that tints them, but that would only work if I wanted my WHOLE image to have a red multiply color effect. Thanks Kex You could just add a red UIView to the top of your UIImageView . Adjust the alpha to make it transparent: let someView = UIView(frame: someImageView.frame) someView

Im developing an image loading library in Swift 4 something like Kingfisher with some extensions to support loading images from URL into an UIImageView . So then i can use this extension on a UICollection or UITableview cell with an UIImageView like this : let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectioncell", for: indexPath) if let normal = cell as? CollectionViewCell { normal.imagview.loadImage(fromURL:imageURLstrings[indexPath.row]) } Basically this is my extension Code , implementing the basic URLSession dataTask and Caching public extension UIImageView {
