iOS开发--UILabel可以显示

UILabel*label;
    
 //设置换行
label.lineBreakMode = UILineBreakModeWordWrap; 
label.numberOfLines = 0;
    
换行符还是“
”
比如NSString * xstring=@"lineone
linetwo"

如果内容是从HTTP返回数据，且换行失败，可以考虑用以下方法测试：

NSString *myNewLineStr = @"
";
myLabelText = [myLabelText stringByReplacingOccurrencesOfString:@"\n" withString:myNewLineStr];
myLabel.text = myLabelText;
