ios - 登录时禁用(登录)按钮
<p><p>您好，我正在开发这个有登录部分的应用程序。我想要的是当我单击登录按钮时，该按钮必须是不可点击的，直到登录成功或失败。我已经尝试添加这一行 <code>doLogin.enabled = NO;</code>
但这没有用。请帮忙。这是我的代码:</p>
<pre><code>- (IBAction)doLogin:(id)sender {
;
}
- (void)loginUser
{
if (! && !)
{
//TODO: check id email pattern is correct
;
[ attemptLoginWithUsername:self.usernameBox.text andPassword:self.passwordBox.text withSuccesBlock:^(AFHTTPRequestOperation *operation, id responseObject)
{
;
UIViewController *newFrontController = nil;
PaMapViewController * vc = [ init];
newFrontController = [ initWithRootViewController:vc];
SWRevealViewController *revealController = self.revealViewController;
;
} andFailureBlock:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSDictionary *dic = ;
#ifdef DEBUG
NSLog(@"dic = %@", dic);
#endif
if ([ isEqual:@"phone"])
{
NSError *jsonError;
NSData *objectData = [ dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData
options:NSJSONReadingMutableContainers
error:&jsonError];
;
}
else
{
;
}
}];
}
else
{
//TODO: show proper message Test
NSLog(@"username or password is empty %@", kBaseURL);
}
}
- (void)showLoginProcess:(BOOL) show
{
];
self.spinner.hidden = !show;
self.usernameBox.hidden = show;
self.passwordBox.hidden = show;
if (show)
{
;
} else
{
;
}
}
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>希望您已经为登录按钮声明了一个属性。让它成为“doLogin”。</p>
<p>你需要做的是</p>
<pre><code>- (IBAction)doLogin:(id)sender
{
;
doLogin.userInteractionEnabled = NO;
}
</code></pre>
<p>当登录成功或失败时写入</p>
<pre><code>doLogin.userInteractionEnabled = YES;
</code></pre>
<p>在相应的区 block 内。</p></p>
