将数组中的文本解析到UILabel中。
原标题:parsing txt from array to UILabel

我实际上开始失去生命的意志了,这个代码片段让我发疯!

我试图获得数学内容。 into

我正在使用一个数组,它是:

-(void)loadText
{
    NSArray *wordListArray = [[NSArray alloc] initWithArray:
    [[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@”mathspractice” ofType:@”txt”]
    encoding:NSMacOSRomanStringEncoding error:NULL] componentsSeparatedByString:@”
”]];
    self.theMathsPractice = wordListArray;
    [wordListArray release];
}

然后我尝试将它传递到*我的标签中

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,100,960,40)];
        myLabel.text = *theMathsPractice;
        [myScrollView addSubview:myLabel];
        [myLabel release];
        }

谁能帮助?

最佳回答

乍一看,您的theMathsPractice似乎是一个NSArray,而不是您想要分配给标签文本属性的NSString。在分配给标签之前,您应该至少将该数组格式化为某种字符串。

(我不肯定你为什么在派任中使用<条码>*,我认为这将造成汇编错误,因为实际上不允许赤 naked的不参事目标C。)

问题回答

我会使用以下内容:

myLable.text = [theMathsPractice componentsJoinedByString:@" "]);
