我正在使用https://github.com/cwRichardKim/TinderSimpleSwipeCards。我已经在viewController中创建了一个Array，其中的数据来自JSON。我希望仅将一定数量的卡创建为JSON数组中的数据。请帮助我，我从最近3天开始这样做，但尚未成功。
这是我的视图控制器中的数组
[self.arrAllCards addObject:model];
//[self.arrExamplecards addObject:model.senderImage];
NSLog(@"%@",_arrAllCards);
//_draggableVC.allCards = _arrAllCards;
//[_draggableVC.exampleCardLabels isEqualToArray:_arrInitationsMainContainer];
if ([_arrAllCards count] >0) {
DraggableViewBackground *draggableBackground = [[DraggableViewBackground alloc]initWithFrame:self.invitationViewContainer.frame];
draggableBackground.exampleCardLabels = [NSMutableArray arrayWithArray:_arrAllCards];
draggableBackground.alpha = 0; //opti
[self.invitationViewContainer addSubview:draggableBackground];
[draggableBackground setNeedsDisplay];
}
和DraggableViewBackground是cwRichardKim提供的View类是
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[super layoutSubviews];
[self setupView];
exampleCardLabels = [NSArray new]; //%%% placeholder for card-specific information
loadedCards = [[NSMutableArray alloc] init];
allCards = [[NSMutableArray alloc] init];
cardsLoadedIndex = 0;
[self loadCards];
}
return self;
}
//%%% sets up the extra buttons on the screen
// to get rid of it (eg: if you are building cards from data from the internet)
-(DraggableView *)createDraggableViewWithDataAtIndex:(NSInteger)index
{
//MGInvitationModel *model = self.exampleCardLabels[index];
DraggableView *draggableView = [[DraggableView alloc]initWithFrame:CGRectMake(0, -50, CARD_WIDTH, CARD_HEIGHT)];//[[DraggableView alloc]initWithFrame:CGRectMake((self.bounds.size.width)/2, (self.bounds.size.height)/2, CARD_WIDTH, CARD_HEIGHT)]; //[[DraggableView alloc]initWithFrame:CGRectMake(0, -40, CARD_WIDTH, CARD_HEIGHT)];
//draggableView.information.text = [exampleCardLabels objectAtIndex:index]; //%%% placeholder for card-specific information
draggableView.delegate = self;
draggableView.layer.cornerRadius = 10.0f;
nameLabel = [[UILabel alloc]initWithFrame:CGRectMake(30, 280, 150, 50)];
nameLabel.font = [UIFont fontWithName:@"Arial" size:12.0f];
nameLabel.text = @"NIVESH";
[nameLabel setTextAlignment:NSTextAlignmentLeft];
nameLabel.textColor = [UIColor blackColor];
[draggableView addSubview:nameLabel];
return draggableView;
}

[loadedCards addObject:newCard];
}

} else {

最佳答案
您可以像这样更改-(void)loadCards方法吗？
-(void)loadCards :(NSArray*) array {
exampleCardLabels = array;
//put here your existing code.
//...
}
还要在DraggableViewBackground.h文件上添加
-(void)loadCards :(NSArray*) array;并从
[self loadCards];方法注释- (id)initWithFrame:(CGRect)frame然后像这样更改此方法-
if ([_arrAllCards count] >0) {
DraggableViewBackground *draggableBackground = [[DraggableViewBackground alloc]initWithFrame:self.invitationViewContainer.frame];
[draggableBackground loadCards:_arrAllCards];
draggableBackground.alpha = 0; //opti
[self.invitationViewContainer addSubview:draggableBackground];
//[draggableBackground setNeedsDisplay];
}
