UITextview中的numberOfLines吗? [英] numberOfLines in UITextview?

问题描述

UIlabel具有numberOfLines属性.它说我的字符串有2行.但是，当我使用UItextview时，我想根据UITextview中文本的长度来分割行数.我该怎么做? UIlabel自动拆分，但UITextview不会拆分.

UIlabel has numberOfLines property. It says my string has 2 lines. But when I use UItextview , I want to split the number of lines based on length of text in UITextview. How can I do it? UIlabel automatically splits, but UITextview does not do it.

推荐答案

这些行应以"\ r"分隔

The lines should be separated by "\r"

这是一个例子:

lblNeedSubscription = [[UILabel alloc] initWithFrame:frame];
[lblNeedSubscription setNumberOfLines:0];  // allows as many lines as needed
[lblNeedSubscription setText:@"To access content\ryou need to be a paid subscriber"];
