Building a titleView programmatically with constraints (or generally constructing a view with constraints)

Question

I\'m trying to build a titleView with constraints that looks like this:

I know how I would do

Answer 1

Here is my implementation of ImageAndTextView

@interface ImageAndTextView()
@property (nonatomic, strong) UIImageView *imageView;
@property (nonatomic, strong) UITextField *textField;
@end

@implementation ImageAndTextView

- (instancetype)init
{
    self = [super init];
    if (self)
    {
        [self initializeView];
    }

    return self;
}

- (void)initializeView
{
    self.translatesAutoresizingMaskIntoConstraints = YES;
    self.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

    self.imageView = [[UIImageView alloc] init];
    self.imageView.contentMode = UIViewContentModeScaleAspectFit;
    self.textField = [[UITextField alloc] init];
    [self addSubview:self.imageView];
    [self addSubview:self.textField];

    self.imageView.translatesAutoresizingMaskIntoConstraints = NO;
    self.textField.translatesAutoresizingMaskIntoConstraints = NO;
    //Center the text field
    [NSLayoutConstraint activateConstraints:@[
        [self.textField.centerXAnchor constraintEqualToAnchor:self.centerXAnchor],
        [self.textField.centerYAnchor constraintEqualToAnchor:self.centerYAnchor]
    ]];

    //Put image view on left of text field
    [NSLayoutConstraint activateConstraints:@[
        [self.imageView.rightAnchor constraintEqualToAnchor:self.textField.leftAnchor],
        [self.imageView.lastBaselineAnchor constraintEqualToAnchor:self.textField.lastBaselineAnchor],
        [self.imageView.heightAnchor constraintEqualToConstant:16]
    ]];
}

- (CGSize)intrinsicContentSize
{
    return CGSizeMake(CGFLOAT_MAX, CGFLOAT_MAX);
}
@end
