objective-c：标签中只显示每个循环迭代的最后一个值

objective-c

objective-c：标签中只显示每个循环迭代的最后一个值,objective-c,foreach,Objective C,Foreach,解析json后得到的名称计数是随机的，即它可以显示从1到100的任意数量的值。我创建了许多标签，如下面的代码所示，但是当我将NSString*name传递给putLabelsInScrollView方法时，label中只显示最后一次迭代的值。有谁能帮我解决这个逻辑，在不同创建的标签中显示不同的名称吗？我无法创建tableview，这本来很容易，稍后会更正标签和textfields的cGRects int i = 0; for(NSDictionary *myJsonD
