ios - 即时更改自定义 UIView 中的标签文本

Question

我有一个名为 TimeTooltipView 的自定义 View 。这是代码:

TimeTooltipView.h

#import <UIKit/UIKit.h>

@interface TimeTooltipView : UIView

@property (weak, nonatomic) IBOutlet UILabel *timeLabel;

-(void)configureView;

@end

TimeTooltipView.m

#import "TimeTooltipView.h"

@implementation TimeTooltipView

-(id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        NSArray *subviewArray = [[NSBundle mainBundle] loadNibNamed:@"TimeTooltipView" owner:self options:nil];
        UIView *mainView = [subviewArray objectAtIndex:0];
        [self addSubview:mainView];

        [self configureView];
    }

    return self;
}

-(void)configureView {
    self.backgroundColor = [UIColor greenColor];
}

@end

我在 View Controller 中添加了一个 TimeTooltipView，如下所示:

TimeTooltipView *timeTooltipView = [[TimeTooltipView alloc] 

initWithFrame: CGRectMake(100, 100, 50, 50)];
timeTooltipView.timeLabel.text = @"TEST";
[self.view addSubview:timeTooltipView];
timeTooltipView.timeLabel.text = @"TEST2";

我需要从 View Controller 即时更改 timeLabel 的文本。使用上面的代码， View 被添加并具有绿色背景色。但标签文本永远不会更改为“TEST”或“TEST2”。

如何即时更改自定义 View 的标签文本？

-(id)initWithFrame:(CGRect)frame {
    NSArray *subviewArray = [[NSBundle mainBundle] loadNibNamed:@"TimeTooltipView" owner:self options:nil];
        //Instead of making it subView just replace it.
        self = [subviewArray objectAtIndex:0];
        self.frame = frame;
        [self configureView];

    return self;
}

-(void)configureView {
    self.backgroundColor = [UIColor greenColor];
}
