You need to get alertView's subViews. Iterate through the array of subview's, it will be having one item of type UILable. Get that UILabel from subview array and for that you can set textAlignment property.
您需要获取alertView 的子视图。遍历子视图的数组，它将具有 UILable 类型的一项。从子视图数组中获取 UILabel，为此您可以设置 textAlignment 属性。
NSArray *subViewArray = alertView.subviews;
for(int x=0;x<[subViewArray count];x++){
if([[[subViewArray objectAtIndex:x] class] isSubclassOfClass:[UILabel class]])
{
UILabel *label = [subViewArray objectAtIndex:x];
label.textAlignment = UITextAlignmentCenter;
}
}

This is just a slightly simplified version of the previous answer but I like to keep things simple. :)
这只是先前答案的略微简化版本，但我喜欢保持简单。:)
for (UIView *view in alert.subviews) {
if([[view class] isSubclassOfClass:[UILabel class]]) {
((UILabel*)view).textAlignment = NSTextAlignmentLeft;
}
}

the code below is not work on iOS7, only before iOS7.
下面的代码不适用于 iOS7，仅在 iOS7 之前。
for (UIView *view in alert.subviews) {
if([[view class] isSubclassOfClass:[UILabel class]]) {
((UILabel*)view).textAlignment = NSTextAlignmentLeft;
}
}
the question Align message in UIAlertView to left in iOS 7solve this problem.
问题在UIAlertView中对齐消息在IOS 7向左解决这个问题。
