I'm having a problem that doesn't seem to have an obvious solution. I've searched around and I've been through all common answers that I could find.
My custom xib views don't show up on the app when I launch. The background is clear, and this xib has 5 image views as you can see below which aren't set to hidden.
The class has about 5 delegates as well which I set from a caller when the delegates have been initialized. The caller of initWithDelegates:
is the parent UIViewController that displays this xib.
CustomView.h
@interface CustomView : UIView<SomeProtocol>
// UI Items - THESE AREN'T SHOWING UP
@property (strong, nonatomic) IBOutlet UIImageView *image1;
@property (strong, nonatomic) IBOutlet UIImageView *image2;
@property (strong, nonatomic) IBOutlet UIImageView *image3;
@property (strong, nonatomic) IBOutlet UIImageView *image4;
@property (strong, nonatomic) IBOutlet UILabel *label;
@property (strong, nonatomic) IBOutlet UIStackView *centerStackView;
- (id)initWithDelegates:(UIViewController*)delegate1 withDelegate2:(NSObject<Delegate2>*)delegate2 withDelegate3:(NSObject<Delegate3>*)delegate3 withDelegate4:(UIViewController<Delegate4>*)delegate4
withDelegate5:(NSObject<Delegate5>*)delegate5;
@end
CustomView.m
@implementation CustomView
- (void)awakeFromNib {
[super awakeFromNib];
}
- (id)initWithDelegates:(UIViewController*)delegate1 withDelegate2:(NSObject<Delegate2>*)delegate2 withDelegate3:(NSObject<Delegate3>*)delegate3 withDelegate4:(UIViewController<Delegate4>*)delegate4
withDelegate5:(NSObject<Delegate5>*)delegate5
{
NSArray * arr =[[NSBundle mainBundle] loadNibNamed:@"CustomView" owner:nil options:nil];
self = [arr firstObject];
self.delegate1 = delegate1;
self.delegate2 = delegate2;
self.delegate3 = delegate3;
self.delegate4 = delegate4;
self.delegate5 = delegate5;
[self setLoopImage];
[self layoutIfNeeded];
return self;
}
@end
What else I've verified:
Any help is appreciated!
UPDATE:
I believe this has something to do with putting the nibs in a nested UIView. In the interface builder, the order is UIViewController -> UIView -> nibs
There doesn't seem to be a method to register nibs from the parent UIViewController as there are in classes like UITableView.
I've also tried:
(id)initWithDelegates
method not init or register the nib in case that was duplicating the object. I did this by removing 1) return self
, 2) the lines that register the nib, and 3) making the method prototype return void - IE (void)initWithDelegates
- This didn't work either.[self addSubview: self.image1]; [self bringSubviewToFront: self.image1]; [self.menuImage setHidden:image1];
[self addSubview: self.image1]; [self bringSubviewToFront: self.image1]; [self.menuImage setHidden:image1];
-- with no luck. Check your Autolayout in your custom XIB. Something the contain does not show because of it. For example: only center vertically & center horizontally. Try to do different autolayout constraint in your view in custom class.
I think something is wrong with layout of your CustomView inside ParentView. Could you please:
Check the frame of CustomView when you add it into the ParentView.
Check constraints that has CustomView inside ParentView. If you don't have them - add it, constraints will iOS the glue how to layout your CustomView. More information about this you can find here Programmatically Creating Constraints
nibs cannot be nested within the structure.
Instead of:
UIViewController -> UIView -> nibs..
It should be:
UIViewController -> Container View -> UIView with nibs.
