格式化UIAlert查看

Question

當按下按鈕時，彈出一個UIAlert視圖。我想要有單獨的文本行，每行有一定的文本。當我目前運行該應用程序時，它會在段落中顯示它。這是代碼：

- (IBAction)popupalert:(id)sender { 
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Lesson Timing" message: 
         @"Lesson 1: 7:40-8:20, Lesson 2: 8:22-9:02, Breakfast Break: 9:02-9:15, Lesson 3: 9:15-9:55, Lesson 4: 9:57-10:37, Lesson 5: 10:39 - 11:19, Second Break: 11:19-11:29, Lesson 6: 11:29-12:09, Lesson 7: 12:11-12:51, Lesson 8: 12:53-1:33, Lunch Break: 1:33-1:58, Private Study: 1:58-2:38, Lesson 9: 2:40-3:15" delegate:nil cancelButtonTitle:@"Done" otherButtonTitles:nil, nil]; 
[alert show]; 

} 

我希望每個課程都在不同的行上。

如果您只是想將文本放在不同的行中，可以通過使用換行符（\n）字符（例如，

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Lesson Timing" 
               message:@"Lesson 1: 7:40-8:20, \nLesson 2: 8:22-9:02, \nBreakfast Break: 9:02-9:15, \nLesson 3: 9:15-9:55, \nLesson 4: 9:57-10:37, \nLesson 5: 10:39 - 11:19, \nSecond Break: 11:19-11:29, Lesson 6: 11:29-12:09, Lesson 7: 12:11-12:51, Lesson 8: 12:53-1:33, Lunch Break: 1:33-1:58, \nPrivate Study: 1:58-2:38, \nLesson 9: 2:40-3:15" 
               delegate:nil 
            cancelButtonTitle:@"Done" 
            otherButtonTitles:nil, nil];
