UIAlertView显示多条消息

Question

如何在不同变量的alertView中显示多条消息？

Answer 1

构建从多个变量所需的NSString，如：

NSString *foo; 
NSString *bar; 
NSString *baz; 
// ... set values for foo, bar and baz ... 
NSString *myMessage = [NSString stringWithFormat:@"%@ %@ %@", foo, bar, baz]; 

然后设置你的警报视图使用复合消息myMessage：

NSString *myTitle = @"xyz"; 
UIAlertView *alert = [[UIAlertView alloc] 
         initWithTitle: myTitle 
         message: myMessage 
         delegate: nil 
         cancelButtonTitle: @"OK" 
         otherButtonTitles: nil]; 
[alert show]; 
[alert release]; 

Answer 2

NSString *string1=@"total time played:30\n"; 
    NSString *string2=@"total score :90\n"; 
    NSString *string3=@"19/2/20010 12:00:77\n"; 
    NSString *string=[NSString stringWithFormat:@"%@%@%@",string1,string2,string3]; 
    UIAlertView *progressAlert = [[UIAlertView alloc] initWithTitle:@"Hello" message:string delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil]; 
    [progressAlert show]; 
    [progressAlert release]; 

Answer 3

你不妨割肉出局你的问题多一点，但根据我对你的问题的理解，你应该只能使用

- (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle otherButtonTitles:(NSString *)otherButtonTitles, ... 

UIAlertView构造函数。然后将您的变量连接成一个NSString对象，并将其作为(NSString*)message传递给对象。

+ (id)stringWithFormat:(NSString *)format, ... 

工厂方法使这个微不足道的。我会推荐reading your options with NSString in the Apple documentation。

Answer 4

NSString *str1=@"Message 1."; 
NSString *str2= @"Message 2."; 
NSString *str3 = @"Message 3"; 


NSString *msg=[NSString stringWithFormat:@"%@\n%@\n%@",str1,str2,str3]; 


FreeCoinsCustomAlert* alert = [[FreeCoinsCustomAlert alloc] initWithTitle:msg 
                    message:nil delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 

[alert show]; 
[alert release];
