iOS开发--UILabel可以显示

 1 UILabel*label;
 2     
 3  //设置换行
 4 label.lineBreakMode = UILineBreakModeWordWrap; 
 5 label.numberOfLines = 0;
 6     
 7 换行符还是“
”
 8 比如NSString * xstring=@"lineone
linetwo"
 9 
10 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：
11 
12 NSString *myNewLineStr = @"
";
13 myLabelText = [myLabelText stringByReplacingOccurrencesOfString:@"\n" withString:myNewLineStr];
14 myLabel.text = myLabelText;
