How to Resolve Incorrect Frame Calculation for UIView After Adding Subviews Dynamically in Objective-C?
I've searched everywhere and can't find a clear answer. I've been banging my head against this for hours. I'm facing an issue with frame calculations in a UIView when I'm adding subviews dynamically. I'm trying to create a custom UIView that contains multiple labels, and I need to adjust the frame of the parent view based on the content of these labels. However, after adding the labels, the frame of the parent view does not adjust as expected, leading to clipping issues. Here's a simplified version of what I'm doing: ```objc - (void)setupLabelsWithTextArray:(NSArray<NSString *> *)textArray { CGFloat totalHeight = 0; for (NSString *text in textArray) { UILabel *label = [[UILabel alloc] init]; label.text = text; label.numberOfLines = 0; // Allow multiple lines [label sizeToFit]; // Adjust the label's size based on its content [self addSubview:label]; // Set the frame for the label label.frame = CGRectMake(10, totalHeight, self.frame.size.width - 20, label.frame.size.height); totalHeight += label.frame.size.height + 10; // Add some spacing between labels } // Update the parent's frame based on the total height of the labels self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, totalHeight); } ``` After calling `setupLabelsWithTextArray:` with an array of strings, I expect the parent view's frame to adjust to fit all the labels, but it seems to be staying the same size. I've checked that the call to `sizeToFit` on each label is working correctly, but the overall container view still doesn't seem to accommodate the added subviews. I've also tried calling `layoutIfNeeded` and `setNeedsLayout` on the parent view after adding the labels, but that hasn’t resolved the issue either. The problem seems to be that the frame update for the parent view happens before the layout passes are completed. I'm working with iOS 14, and I would appreciate any guidance on how to ensure that the parent view's frame is correctly calculated after dynamically adding subviews. Any help would be greatly appreciated! Thanks in advance!
