转IPhone之自定义弹出窗口

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];

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];
}

- (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]; } }
