iOS开发-自定义UIAlterView(iOS 7)
App中不可能少了弹框，弹框是交互的必要形式，使用起来也非常简单，不过最近需要自定义一个弹框，虽然iOS本身的弹框已经能满足大部分的需求，但是不可避免还是需要做一些自定义的工作。iOS7之前是可以自定义AlterView的，就是继承一下UIAlterView，然后初始化的时候通过addSubview添加自定义的View，但是iOS7之后这样做就不行了，不过还好有开源项目可以解决这个问题。
iOS默认弹框
viewDidLoad中添加两个按钮，代码如下:

UIButton *orignalBtn=[[UIButton alloc]initWithFrame:CGRectMake(100, 40, 100, 50)];[orignalBtn setBackgroundColor:[UIColor greenColor]];[orignalBtn setTitle:@"iOS弹框" forState:UIControlStateNormal];
[orignalBtn addTarget:self action:@selector(orignalShow) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:orignalBtn];
UIButton *customlBtn=[[UIButton alloc]initWithFrame:CGRectMake(100, 140, 100, 50)];[customlBtn setBackgroundColor:[UIColor redColor]];[customlBtn setTitle:@"自定义弹框" forState:UIControlStateNormal];
[customlBtn addTarget:self action:@selector(customShow) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:customlBtn];

响应默认弹框事件:

-(void)orignalShow{
UIAlertView *alterView=[[UIAlertView alloc]initWithTitle:@"提示" message:@"博客园-Fly_Elephant" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alterView show];
} |
效果如下:
自定义弹框
主要解决iOS7之后的系统无法自定义弹框的问题，使用开源项目，项目地址:https://github.com/wimagguc/ios-custom-alertview,其实就是自定义了一个类:
