自定义UIAlertView iPhone [英] Custom UIAlertView iphone

问题描述

我有问题..我使用了 http://kwigbo.com/post/318396305/iphone-sdk-custom-uialertview-background-color 创建我自己的自定义UIAlertView. 我不知道为什么，但是这行不通:

I have a problem .. I used this http://kwigbo.com/post/318396305/iphone-sdk-custom-uialertview-background-color to create my own custom UIAlertView. I do not know why but this will not work:

UILabel *theTitle = [theAlert valueForKey:@"_titleLabel"];

[theTitle setTextColor:[UIColor redColor]];

UILabel *theBody = [theAlert valueForKey:@"_bodyTextLabel"];

[theBody setTextColor:[UIColor blueColor]];

标题的颜色不变..texbody的颜色还可以.

the color of the title does not change .. the color of texbody it's ok.

1. 如何自定义按钮?

推荐答案

使用自定义UIAleartView实现了同样的事情.

Hi Achieved same thing using custom UIAleartView.

1. 按如下所示进行自定义视图.

1. Make a custom view as follows.

UIView *tempView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 5.0f, 262.0, 49)]; 
tempView.backgroundColor = [UIColor clearColor];

UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(12, 0, 262.0, 49)];
lblTitle.font = [UIFont fontWithName:@"Arial" size:22.0f];
lblTitle.textColor = [UIColor whiteColor];
lblTitle.textAlignment = UITextAlignmentCenter;
lblTitle.text = @"Subscribe";
 lblTitle.backgroundColor = [UIColor clearColor];
 [tempView addSubview:lblTitle];

alreadySubscriber = [[UIButton alloc] initWithFrame:CGRectMake(12, 260, 262.0, 50)];
alreadySubscriber.layer.cornerRadius = 25.0f;
[alreadySubscriber setTitle:@"Already a subscriber" forState:UIControlStateNormal];
[alreadySubscriber setBackgroundImage:[UIImage imageNamed:@"BTN0.png"] forState:UIControlStateNormal];
[alreadySubscriber setBackgroundImage:[UIImage imageNamed:@"BTN1.png"] forState:UIControlStateSelected];
[tempView addSubview:alreadySubscriber];

将此内容插入UIAleartView

Insert this in UIAleartView

[self insertSubview:tempView atIndex:0];
[self setNeedsLayout];

已覆盖布局子视图，因为您已经将所有其他控件向下推等于视图高度.

->基本上，重要的是将UIAleartView的标题隐藏在标签后面.

-> basically matter is to hide UIAleartView's title behind a label.
