从变量目标c插入换行符

Question

I am pulling data into my iphone application using xml. The xml value is then placed in a variable.

example variable:

123 London road \n London \n England

The variable is then set as a label.

I want the line breaks to appear in the label, instead it is printing \\n.

If i manually set the label value

locationLabel.text = @"123 London road \n London \n England"

It works as i want it to.

Can anyone explain this?

您必须将子串\\n （由字符\\和n ）替换为实际的换行符（在\\n表示的C源代码中），例如使用NSString的替换方法 ：

NSString *res = [myStr stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"];
