我正在开发一个相当简单的应用程序，它应该从一个数组中随机显示 2 个单词。现在它正在工作，除了...... 为什么有些文字被缩短了？ 我猜想无论字符串“recipe”以多少字符开头，即使动态更改，它也可以容纳的最大字符数。因此，例如，当它以“Raw Taco”开头时，它会缩短“Boiled Hotdog”等较长的短语。最好的解决方法是什么？

这是我正在使用的代码（抱歉，它没有完全缩短为基本位）：

@implementation C4WorkSpace

{
    C4Shape * red; //, *green, *blue;
    NSArray * foodz, *cookz;
    C4Label * displaytask;
    C4Sample *sample;
    NSString *recipe, *startRecipe;
    int COOKZtaskpicked;
    int FOODZtaskpicked;
}

-(void)setup{

    startRecipe = [NSString stringWithFormat:@"I want to make this really long to start with"];

    C4Font *font = [C4Font fontWithName:@"Avenir" size:40.0f];
    C4Label *label = [C4Label labelWithText:@"Order Up!" font:font];
    label.center = CGPointMake(self.canvas.center.x, self.canvas.height / 3.0f);

    [self.canvas addLabel:label];

    //[self setupShapes];
    //    [self setupLabels];
    red.fillColor = [UIColor colorWithRed:0.9f green:0.0f blue:0.0f alpha:0.7f];

    sample = [C4Sample sampleNamed:@"C4Loop.aif"];
    [sample prepareToPlay];


    // - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - \\
    // FOOD

    foodz =  @[ @"Sushi", @"Burger", @"Salad", @"Taco", @"Nachos", @"Hotdog" ];
    cookz =  @[ @"Baked", @"Boiled", @"Fried", @"Raw", @"Burnt", @"Rotten" ];
    [self changeFOODZtask]; // calls the function down below
    displaytask = [C4Label labelWithText:recipe];
    [displaytask addGesture:TAP name:@"tap" action:@"tapped:"];
    //[displaytask gestureForName:@"tap"]; // set double tap
    [self listenFor:@"tapped:" fromObject:displaytask andRunMethod:@"changeFOODZtask"];

    displaytask.center = self.canvas.center;
    //
    [self.canvas addSubview:displaytask];


    //displaytask = [C4Label labelWithText:cookz[0]];
    //[self changeCOOKZtask]; // calls the function down below
    //[displaytask addGesture:TAP name:@"tap" action:@"tapped:"];
    //[displaytask gestureForName:@"tap"]; // set double tap
    //[self listenFor:@"tapped:" fromObject:displaytask andRunMethod:@"changeCOOKZtask"];

    //displaytask.center = self.canvas.center;
    //
    //[self.canvas addSubview:displaytask];


}

// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - \\
// Random FOODZ Picker
-(void) changeFOODZtask
{
    C4Log(@"changing task");
    FOODZtaskpicked = [C4Math randomIntBetweenA:0 andB: [foodz count] ];
    COOKZtaskpicked = [C4Math randomIntBetweenA:0 andB: [cookz count] ];

    recipe = [NSString stringWithFormat:@"%@ %@", cookz[COOKZtaskpicked],foodz[FOODZtaskpicked]];
    displaytask.text = recipe;
    C4Log(@"%@", recipe);

    [sample play];

    //    displaytask.text = foodz[FOODZtaskpicked];
    //    [displaytask sizeToFit];
}

// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - \\

如果我理解正确，C4Label 是 UILabel 子类吗？我的猜测是字符串被缩短了，因为框架中没有足够的空间让标签必须呈现整个字符串。所以，你有两个选择：

  1. 更改框架的大小或
  2. 让字体变小

如果您想做 1，建议您使用 XIB 文件创建布局并适当设置尺寸约束。对于2，将标签上的属性adjustsFontSizeToFitWidth设置为YES

您的代码中有答案，但已被注释掉。

[displaytask sizeToFit];

问题不在于字符串。您可以看到，当您记录它们时，它们是完整的。

问题在于C4Label，显示它们的开头是基于起始文本的框架。所以，当你从短文本开始时，显示的大小只有“Raw Taco”，但当“Rotten Sushi”出现时，它没有足够的空间来显示。当您调用sizeToFit时，它会检查您需要将当前字符串保存在多大的框架中并适当地text更改框架。你可以在这里C4Label阅读更多关于它的信息。
