如何仅在UIAlertView中对齐标题 [英] How to align only the title in UIAlertView

问题描述

我想只将UIAlertView中的标题居中对齐，而消息则应左对齐.

I would like to align center only the title in UIAlertView, while the message should be align left.

我现在正在做

((UILabel*)[[alert subviews] objectAtIndex:1]).textAlignment = NSTextAlignmentCenter;

但是它也使消息居中对齐.

But it aligns center also the message.

推荐答案

我不会尝试修改UIAlertView的默认标签，而是应该创建一个新的UILabel并将其添加为子视图.

I wouldn't try to modify the default labels of the UIAlertView, instead you should create a new UILabel and add it as a subview.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Centered Title" message:@"\n\n\n" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(12.0, 24.0, 250.0, 80.0)];
label.numberOfLines = 0;
label.textAlignment = NSTextAlignmentLeft;
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.text = @"Here is an example of a left aligned label in a UIAlertView!";
[alert addSubview:label];
[alert show];
