Is it possible to tag a uiimage in uiimageview individually?

由 最后都变了- 提交于 2021-01-29 21:47:29
问题 I searched in the class reference of UIImageView and UIImage, but did not find any info on tagging. In my code, I tagged all of the images in my NSMutableArray of images for my UIImageView, so I could retrieve the tag later: [[images objectAtIndex:0] setTag:1]; [[images objectAtIndex:1] setTag:2]; [[images objectAtIndex:2] setTag:3]; ... This causes my application to crash when I run it. The output reads: 2013-08-08 11:26:48.596 Tap Me[8145:c07] -[UIImage setTag:]: unrecognized selector sent

Circular Image in UITableViewCell

由 空扰寡人 提交于 2021-01-29 05:18:17
问题 I'm trying to create circular Images inside of my TableViewCell but something is going wrong. I guess that the cornerRadius is to big because there is not any Image displayed with this Code. If I set the cornerRadius on 30 for example, I can see the Images rounded but not in a clear circle .Why is this not working ? override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { var cell = tableView.dequeueReusableCell(withIdentifier: "QuestionLine")

TableView to display different images on new controller

由 无人久伴 提交于 2021-01-28 15:12:42
问题 I have finally created a tableview that will be populated with a certain amount of options for the user to click. Ideally, I would like the user to click a row, which will display a image on a second controller depending on the choice the user makes. For instance, "photo1" would display 1 picture on Controller B, while "photo 2" would display a different picture on Controller B. What code can I implement into my existing table view code to send to the second controller? import UIKit class

ios圆角图片的实现

由 牧云@^-^@ 提交于 2020-12-19 10:15:52
图片做圆角是非常常见的，一般用做用户头像什么，ios中怎么实现呢： 1.layer层修改 UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"huabianwl003"]]; imageView.center = self.view.center; [self.view addSubview:imageView]; [imageView.layer setCornerRadius:imageView.frame.size.width/2]; [imageView.layer setMasksToBounds:YES]; 这里注意一点，使用了cornerRaius后，shadow投影就无效果了，怎么样能又是圆角又有投影呢，做两层吧！ 这个方式是ios开发中最常用的，方便简单，但是开销的性能比较大，尤其在tableView中重用的cell里面使用。具体消耗可以看看这篇文章： http://www.cocoachina.com/ios/20150803/12873.html 2.重绘图片 - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view,

Image in collectionView cell causing Terminated due to memory issue

由 拟墨画扇 提交于 2020-12-15 05:18:10
问题 I looked at several answers for this problem but none helped. vc1 is a regular vc, I grab 20 images from firebase, in vc2 I use ARKit to display those images upon user selection. I have a collectionView in vc2 that paginates 20 more images from firebase. The problem is when the next 20 images are loading and I start scrolling, the app crashes with Message from debugger: Terminated due to memory issue . When scrolling those new images, I look at the memory graph and it shoots up to 1 gig, so
