帮助在警报视图中添加字符串
我有一个相当于我想插入 UIAlertView 内部的文本字段的字符串。
NSString *finalScore = [[NSString alloc] initWithFormat:[counter2 text]];
UIAlertView *myAlertView = [[UIAlertView alloc]
initWithTitle:finalScore
message:@"You scored X points"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"OK", nil];
[myAlertView show];
[myAlertView release];
我想用字符串“finalScore”中的分数替换“X”，
我知道如何将其与分数一起使用，您只需在消息部分下输入不带引号的字符串名称即可，但我也想要那里的文本和绳子一起。
非常感谢， 追赶
I have a sting that is equal to a text field that i want to insert inside of a UIAlertView.
NSString *finalScore = [[NSString alloc] initWithFormat:[counter2 text]];
UIAlertView *myAlertView = [[UIAlertView alloc]
initWithTitle:finalScore
message:@"You scored X points"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"OK", nil];
[myAlertView show];
[myAlertView release];
I want to replace"X" with the score from the string "finalScore"
I know how to have it just with the score, you would simple just enter the strings name without quotes under the message section, but i want the the text there too along with the string.
Thanks a bunch,
Chase

将您的
message:参数替换为：另外，请注意，您的
finalScore的原始代码使用不带任何参数的字符串格式，这要么是无操作，要么是不安全的（如果它包含%符号）。您还泄漏了finalScore对象。Replace your
message:parameter with:Also, note that your original code for
finalScoreuses string formatting without any arguments, which is either a no-op or unsafe (if it contains a%symbol). You are also leaking yourfinalScoreobject.尝试如下操作，并将其作为
message变量传递给 UIAlertView 的初始化：您可能需要根据
[counter2 text] 产生的类型更改有关格式化字符串的一些详细信息，但是，尽管上面的方法应该适用于您将遇到的许多情况。Try something like the following, and pass it as the
messagevariable to UIAlertView's initialization:You might have to change some details about the formatting string depending on the type that comes out of
[counter2 text], however, though the above should work in many of the cases you'll encounter.代替：
使用：
Instead of:
use:
