Question

我有一个名为TimeTooltipView的自定义视图。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

我在视图控制器中添加了一个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";

我需要从视图控制器动态更改timeLabel的文本。使用上面的代码，视图将被添加并具有绿色背景颜色。但标签文本永远不会改为“TEST”或“TEST2”。

如何动态更改自定义视图的标签文字？

-(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];
}

即时更改自定义UIView中的标签文本
