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:
- I made sure that the xib file is properly selected under "Custom Class" in the interface builder.
- I've walked through the code to make sure there are no crashes or obvious issues.
- The xib doesn't appear to have any obvious issues in interface builder such as being set to HIDDEN.
- The 5 IBOutlet ImageViews get a memory address and aren't nil.
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:
- Setting the background color in the xib to make sure it shows up. It doesn't. However if I set the background color to red in the parent where I added the view in interface builder, it turns red. (See Figure 1), and my xib file is shown in Figure 2
- Over-rode initWithFrame to make sure its being called. It is called.
- Thinking that the view may be instantiated twice, one via autolayout and one via my custom init method, I tried making the
(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 - I.E.(void)initWithDelegates
- This didn't work either. - I tried these lines within initWithDelegates :
[self addSubview: self.image1]; [self bringSubviewToFront: self.image1]; [self.menuImage setHidden:image1];
-- with no luck.
