斷行

Question

在我的網頁基礎的應用，我想使用的UILabel斷行，我嘗試用下面的編碼，

@"The farmer and his wife were entranced with joy and danced cheerfully because of their goose lays \n a golden egg", 


self.titlestring.frame = CGRectMake(53, 620, 0, 37); 
self.titlestringcop.frame = CGRectMake(53, 620, 918, 37); 
[self fadein]; 
[self.titlestring setText:self.dataobject1]; 
[self.titlestringcop setText:self.dataobject1]; 
textstring.numberOfLines = 0; 
titlestringcop.numberOfLines = 0; 
CGSize labelSize = [textstring.text sizeWithFont:textstring.font 
           constrainedToSize:textstring.frame.size 
            lineBreakMode:textstring.lineBreakMode]; 
CGSize labelSize1 = [titlestringcop.text sizeWithFont:titlestringcop.font 
            constrainedToSize:titlestringcop.frame.size 
             lineBreakMode:titlestringcop.lineBreakMode]; 
textstring.frame = CGRectMake(
           textstring.frame.origin.x, textstring.frame.origin.y, 
           textstring.frame.size.width, labelSize.height); 
titlestringcop.frame = CGRectMake(
            titlestringcop.frame.origin.x, titlestringcop.frame.origin.y, 
            titlestringcop.frame.size.width, labelSize1.height); 

但不表現出任何區別嗎？請告訴我錯在我的代碼？

試試這個行添加這些行也代碼&檢查：

textstring.lineBreakMode = UILineBreakModeWordWrap; 

titlestringcop.lineBreakMode = UILineBreakModeWordWrap;
