Question

所以我不知道以任何方式绘制文本或字符串而是UILabel。所以我初始化了标签，但它一直在崩溃我的应用程序。

以下是初始化标签并导致崩溃的方法：

- （void）setupScore {

scoreLabel = [NSString stringWithFormat:@"%d", score];
scoreLabel.frame = CGRectMake(262, 250, 100, 40);
[scoreLabel setText: scoreString];

//normally you'll want a transparent background for your label
scoreLabel.backgroundColor = [UIColor clearColor]; 

//you can use non-standard fonts
[scoreLabel setFont:[UIFont fontWithName:@"TimesNewRoman" size: 1.0f]];

//change the label's text color
scoreLabel.textColor = [UIColor whiteColor];

//add it to your view
scoreLabel.transform = CGAffineTransformMakeRotation(89.53);
[self addSubview:scoreLabel]; }

- （void）setupPausedLabel {

pausedLabel = [NSString stringWithFormat:@"Tap To Resume"];
pausedLabel.frame = CGRectMake(262, 250, 100, 40);
[pausedLabel setText: @"Tap To Resume"];

//normally you'll want a transparent background for your label
pausedLabel.backgroundColor = [UIColor clearColor];

//you can use non-standard fonts
[pausedLabel setFont:[UIFont fontWithName:@"TimesNewRoman" size: 1.0f]];

//change the label's text color
pausedLabel.textColor = [UIColor whiteColor];

//add it to your view
pausedLabel.transform = CGAffineTransformMakeRotation(89.53);
[pausedLabel setHidden: YES];
[self addSubview:pausedLabel]; }

感谢您的帮助！

Answer 1

你在做：

scoreLabel = [NSString stringWithFormat:@"%d", score];

你应该这样做：

scoreLabel = [[UILabel alloc] init];    // And release it somewhere
scoreString = [NSString stringWithFormat:@"%d", score];

和pauseLabel相同。

Answer 2

您正在使用NSString类初始化您的标签，它应该是UILabel。确保使用良好的格式化程序生成字符串：％d表示整数，％@表示NSString对象。选中此doc以查找相应的说明符：

NSString* scoreString = [NSString stringWithFormat:@"%d", score];
NSString* anotherString = @"Tap To Resume";
NSString* pausedString = [NSString stringWithFormat:@"%@", anotherString];

Answer 3

你的第一行是错的。

scoreLabel = [NSString stringWithFormat:@"%d", score];

scoreLabel=[[UILable alloc]init];
scoreLabel.text=[NSString stringWithFormat:@"%i",score];

NextMethod中的相同问题

pausedLabel = [NSString stringWithFormat:@"Tap To Resume"];

这不对

    pausedLabel=[[UILable alloc]init];
pausedLable.text=[NSString stringWithFormat:@"Tap To Resume"];

UILable text你正在弄乱的属性，所以它会给你崩溃的问题

-(void) setupScore{

 scoreLabel.text = [NSString stringWithFormat:@"%d", score];
scoreLabel.frame = CGRectMake(262, 250, 100, 40);

[scoreLabel setText：scoreString];

//normally you'll want a transparent background for your label
scoreLabel.backgroundColor = [UIColor clearColor]; 

//you can use non-standard fonts
[scoreLabel setFont:[UIFont fontWithName:@"TimesNewRoman" size: 1.0f]];

//change the label's text color
scoreLabel.textColor = [UIColor whiteColor];

//add it to your view
scoreLabel.transform = CGAffineTransformMakeRotation(89.53);
[self.view addSubview:scoreLabel];

}

它正常工作我在viewDidLoad中调用它

- (void)viewDidLoad

{ [super viewDidLoad];

scoreLabel=[[UILabel alloc]init];

scoreString=[NSString stringWithString:@"1221"];

score=10;

[self setupScore];

scoreString=[NSString stringWithString:@"11"];


[self setupScore];

scoreString=[NSString stringWithString:@"333"];


[self setupScore];

[self setupScore];

scoreLabel.text=@"okey...";

}

UILabels崩溃我的应用程序
