问题 I have a UICollectionView that shows images, similar to cover art, or iBooks. I would like for it to show the title of the audio clip underneath the UIImageView. I have in my MainWindow.xib a View Controller with a UICollectionView inside it. I also built a NibCell.xib for the cell itself. In the Cell, I have a UIImageView that fills up all but the bottom 30 px of the cell. In this area I add a UILabel. I give the UIImageView a tag of 100 and UILabel a tag of 200, and in my code I put: -

Can't set shadow on UICollectionViewCell and have rounded corners. Can only make one work at a time

由 吃可爱长大的小学妹 提交于 2019-12-05 21:32:57
I have a UICollectionViewCell subclass and I need to round its corners and add a shadow as well. The cell looks like a square card, and the cells have a good amount of space in-between them. So "underneath" every cell, I would like to add some shadow. I can successfully do this, but then my cell only has rounded corners on the bottom. The top just has normal corners. I need rounded corners for all four corners. I have found solutions on here for UIViews that recommend adding a separate UIView as a subview , but I would prefer to avoid this for performance reasons. I did find one solution which

问题 I have UICollection in which there will be number of Students items and each item having switch inside it used for recording attendance.

Initializing a custom UICollectionViewCell

由 Deadly 提交于 2019-12-05 18:50:22
I have a custom UICollectionViewCell that has a custom background view which is drawn using one of several colour schemes. The colour scheme for the background view is set in my custom initializer -(id)initWithFrame:andColourPalette: for the View. I have a similar custom initialiser in my UICustomViewCell subclass but I can't figure out how to call this initialiser when I am setting up the cell in cellForItemAtIndexPath: Can anyone help me do this? Or offer alternative solution for passing this Dictionary of colours into the Cell to pass on to the subView? EDIT to show more detail: This is

What is the correlation between bounds.size and frame.size when animating UICollectionViewCell

由 妖精的绣舞 提交于 2019-12-05 14:36:09
I've read on several posts (like https://stackoverflow.com/a/5340339/1084822 and https://stackoverflow.com/a/15582466/1084822 ) that to resize a UIView with animation, we can't animate the frame and we must do it with a mix of bounds.size, bounds.origin and position. However, I can't find what is the correlation between those properties and those of the frame. I have a UICollectionView with a custom layout. When a cell is deleted, the layout is refreshed and every cell gets its new frame through the prepareLayout and layoutAttributesForElementsInRect: methods. Then, the
