UILabel 文字不会显示 [英] UILabel text won't display

问题描述

我在使用 UILabels 构建的 iOS 应用程序中遇到了问题:尽管对它们进行了初始化，但我编写的文本不会显示出来，而且我对我应该做的事情束手无策.

I'm having trouble in an iOS app I'm building with UILabels: despite initializing them the text I programmed won't show up and I'm at wits' end about what I should do.

例如，这是我遇到此问题的应用程序屏幕之一:

For example, this is one of the app's screens in which I have this problem:

欢迎.m

@interface Welcome()

@end

@implementation Welcome

-(void) viewdidLoad{
    [super viewDidLoad];
    UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 140, 47)];
    [self.view addSubview: label];
    label.text = @"Benvinguts a la pràctica de iOS I";
    label.numberOfLines = 4;

}

-(IBAction) buttonPressed: (id) sender
{

   [self performSegueWithIdentifier:@"Tutorial1" sender:self];
}


@end

你能帮我解决这个问题吗?

Could you help me out in fixing this?

推荐答案

需要添加一个textColor:

You need to add a textColor:

   UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 140, 47)];
    [self.view addSubview: label];
    label.text = @"Benvinguts a la pràctica de iOS I";
    label.numberOfLines = 4;
    label.textColor = [UIColor blackColor];
