ios - 从 UIView 内的 NSMutableArray 垂直显示 UILabel
<p><p>我有一个数组对象列表，我将其传递给循环并将其动态显示为 <code>UILabel</code>。但是我需要这些值以垂直显示它。以下是我的代码，</p>
<pre><code> labelArrays = ;
//inside a method with a loop am passing the array and creating the labels.
-(void) createlabel:(CGRect) frame{
float xCoordinate = frame.origin.x;
float yCoordinate = frame.origin.y;
int labelHeight =30;
int gapBetweenTwoLabels =2;
int labelWidth = 100;
for(int counter = 0; counter < ; counter++){
UILabel *label = [initWithFrame:CGRectMake(xCoordinate,yCoordinate,labelWidth,labelHeight)];
label.text = ;
;
xCoordinate = xCoordinate + labelWidth + gapBetweenTwoLabels;
}
}
//frame
;
</code></pre>
<p>这显示我为</p>
<pre><code>one two three four five six
</code></pre>
<p>但我需要它</p>
<pre><code>one two three
four five six
</code></pre>
<p>谁能建议我如何实现它？注意:我在 UIView 中使用此方法，而不是在 Controller 中。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>按照@Larme 所述更改您的 y 坐标</p>
<pre><code>labelArrays = ;
</code></pre>
<p>如果你想输出如下</p>
<blockquote>
<p>one <br/>
two <br/>
three <br/>
four <br/>
five <br/>
six <br/></p>
</blockquote>
<pre><code>-(void) createlabel:(CGRect) frame {
CGFloat xCoordinate = frame.origin.x;
CGFloat yCoordinate = frame.origin.y;
CGFloat labelHeight = frame.size.height;
CGFloat labelWidth = frame.size.width;
CGFloat gapBetweenTwoLabels = 2;
for(int counter = 0; counter < ; counter++) {
UILabel *label = [initWithFrame : CGRectMake(xCoordinate, yCoordinate, labelWidth, labelHeight)];
label.text = ;
;
yCoordinate = yCoordinate + labelHeight + gapBetweenTwoLabels;
}
}
</code></pre>
<p>但如果你想输出为:</p>
<blockquote>
<p>one
two
three <br/>
four
five
six <br/></p>
</blockquote>
<pre><code>-(void) createlabel:(CGRect) frame {
CGFloat xCoordinate = frame.origin.x;
CGFloat yCoordinate = frame.origin.y;
CGFloat labelHeight = frame.size.height;
CGFloat labelWidth = frame.size.width;
CGFloat gapBetweenTwoLabels = 2;
for(int counter = 0; counter < ; counter++) {
UILabel *label = [initWithFrame : CGRectMake(xCoordinate, yCoordinate, labelWidth, labelHeight)];
label.text = ;
;
if((counter+1)%3 == 0) {
xCoordinate = 0;
yCoordinate = yCoordinate + labelHeight + gapBetweenTwoLabels;
} else {
xCoordinate = xCoordinate + labelWidth + gapBetweenTwoLabels;
}
}
}
</code></pre>
<p>函数调用</p>
<pre><code>;
</code></pre></p>
