我已经IBDesignables在接口视图中创建了可重用的类来渲染xib.
@interface ReusableView ()
@property (nonatomic, strong) UIView *contentView;
@end
@implementation ReusableView
- (instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
[self setupXib];
return self;
}
- (instancetype)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
[self setupXib];
return self;
}
- (void)setupXib {
self.contentView = [self loadFromNib];
self.contentView.frame = self.bounds;
self.contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self addSubview:self.contentView];
}
- (UIView *)loadFromNib {
NSBundle *bundle = [NSBundle bundleForClass: [self class]];
UINib *nib = [UINib nibWithNibName:NSStringFromClass([self class]) bundle:bundle];
UIView *view = (UIView *)[[nib …Run Code Online (Sandbox Code Playgroud) 假设我们有 InvoiceDataModel 数组
private let invoices Variable<[InvoiceDataModel]> = Variable([])
class InvoiceDataModel {
let id: Variable<Int>
var entity: Variable<InvoiceDto>
var isSelected: Variable<Bool>
}

点击复选框时,我正在更改 isSelected 的值。我想要实现的是对 isSelect 更改做出反应:
var amount: Double)是否可以观察整个数组并对元素更改中的单个属性做出反应?不知道我应该如何实现这一目标。
也许我对这个案子的处理方法是完全错误的。但是我不确定我应该如何以不同的方式在这里运作。
