ios - 单击按钮时将句子的单词放入不同的透明标签中

Question

我有一个存储在 NSMutablesstring 中的句子，我有一个按钮，当点击时，它将句子单词加载到标签中，例如，以“我是男孩”为例，当单击按钮时，它会加载“ i" 进入一个标签，"am" 进入另一个标签，"a" 进入另一个标签，"boy" 进入另一个标签。

Answer 1

NSString *sentence = @"i am a boy";
NSMutableArray *words = [sentence componentsSeparatedByString:@" "];

CGFloat xVal = 0.0;

for( NSString *word in words ) {

    UILabel *wordLabel = [[UILabel alloc] initWithFrame:CGRectMake(xVal,0,200,40)];
    wordLabel.backgroundColor = [UIColor clearColor];
    wordLabel.textColor = [UIColor blackColor];
    wordLabel.text  = word;
    xVal+=200;

    [self.view addSubview:wordLabel];
}

Answer 2

NSArray* labels = [@"i am a boy" componentsSeparatedByString: @" "];
CGFloat xOffset = 0.0;
for NSString *labeltext in labels
   UILabel *wordLabel = [[UILabel alloc] initWithFrame:CGRectMake(xOffset,0,300,40)];
   wordLabel.text  = word;
   xOffset+=200;
   [self.view addSubview:wordLabel];

Answer 3

您可以将“我是男孩”拆分为数组。

NSString* example = @"I am a boy";
NSArray *arr = [example componentsSeparatedByCharactersInSet:
          [NSCharacterSet characterSetWithCharactersInString:@" "]];

然后，您可以将 Text 设置为 UILabel
