从同一个xib加载另一个UIView以添加为子视图

Question

I have UITableView is Storyboard. I try to create UITableViewCell in Xib and register it in UITableView as that:

-(void)viewDidLoad{
    [super viewDidLoad];
    UINib *nib = [UINib nibWithNibName:@"FlipperTableViewCell" bundle:nil];
    [self.tableView registerNib:nib forCellReuseIdentifier:@"fliperCell"];
}

It work perfectly.

But this cell must have one view inside and flip it to another view when button on first view pressed.

I create another two views in same xib. File's owner is FliperTableViewCell class. Class of first view is FliperTableViewCell.

But now a can't figure out how to add second view (UIView) as subview in first view (UITableViewCell), which loaded by table view. I try to get second view from loadNibNamed:, but it became infinite cycle.

@implementation FlipperTableViewCell
-(id)initWithCoder:(NSCoder *)aDecoder{
    if (self = [super initWithCoder:aDecoder]){
        [self addSubview:[[[NSBundle mainBundle] loadNibNamed:NSStringFromClass(self.class) owner:self options:nil] objectAtIndex:1]];
    }
    return self;
}

What is another way to get second view from same xib and add it as subview when first view loaded?

Answer 1

problem was solved when I replace

[self.tableview registerNib:nib forCellReuseIdentifier:@"FlipperTableViewCell"];

to

[self.tableview registerClass:[FlipperTableViewCell class] forCellReuseIdentifier:@"FlipperTableViewCell"];

then remove first view from xib and rewrite FlipperTableViewCell to initiate in code

#import "FlipperTableViewCell.h"

@interface TableViewCell ()
@property (nonatomic, strong) UIView *firstView;
@property (nonatomic, strong) UIView *secondView;
@end

@implementation FlipperTableViewCell
-(instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]){
        NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass(self.class) owner:self options:nil];
        self.firstView = nibObjects[0];
        self.secondView = nibObjects[1];
        [self.contentView addSubview:self.firstView];
        self.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    return self;
}

// this is for test changing views
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
    if (self.contentView.subviews[0] == self.firstView){
        [self.firstView removeFromSuperview];
        [self.contentView addSubview:self.secondView];
    }
    else{
        [self.secondView removeFromSuperview];
        [self.contentView addSubview:self.firstView];
    }
}

@end
