iOS中UIAlertView的使用方法
UIAlertView * alertView=[[UIAlertView alloc]initWithTitle:nil
message:@"真的要退出?"
delegate:self
cancelButtonTitle:@"确定"
otherButtonTitles:@"取消", nil];
alertView.tag=11;
[alertView show];
然后实现UIAlertViewDelegate的代理方法
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
//执行的代码
}2.3带输入框的Alert
//登陆弹出框:一个文本输入框,一个密码框
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:@"Password" message:@"Please enter your credentials" delegate:self
cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
//设置AlertView的样式
[alertView setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
[alertView show];
//登陆弹出框:一个文本输入框,一个密码框
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:@"Password" message:@"Please enter your credentials" delegate:self
cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
//设置AlertView的样式
[alertView setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
[alertView show];
