初始化代码：

if (!_alertView)

{

_alertView = [[UIAlertView alloc] initWithTitle:title message:@"\n\n\n" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"登录", nil];

_alertView.delegate = self;

usernameField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 50.0, 260.0, 25.0)];

usernameField.delegate = self;

usernameField.placeholder = @"用户名";

usernameField.autocapitalizationType = UITextAutocapitalizationTypeNone;

usernameField.autocorrectionType = UITextAutocorrectionTypeNo;

usernameField.returnKeyType = UIReturnKeyNext;

usernameField.keyboardType = UIKeyboardTypeEmailAddress;

[usernameField setBackgroundColor:[UIColor whiteColor]];

[_alertView addSubview:usernameField];

passwordField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 85.0, 260.0, 25.0)];

passwordField.delegate = self;

passwordField.placeholder = @"密码";

passwordField.secureTextEntry = YES;

passwordField.returnKeyType = UIReturnKeyGo;

[passwordField setBackgroundColor:[UIColor whiteColor]];

[_alertView addSubview:passwordField];

CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, 00.0);

[_alertView setTransform:myTransform];

}else {

_alertView.title = title;

usernameField.text = nil;

passwordField.text = nil;

}

[usernameField becomeFirstResponder];

[_alertView show];

自定义按钮事件代码：

其中didDismissWithButtonIndex参数为：第几个按钮点击事件

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{

if (buttonIndex == 1) {

self.userName = usernameField.text;

self.password = passwordField.text;

[self performSelector:@selector(doResponse) withObject:nil afterDelay:0.1];

}

}
