所以我已经将我的应用程序发布到AppStore一段时间了，所有类型的设备都在使用它。最新版本在iPhone 6上使用ios 8.4.1以及6 +。
我收到用户的反馈，说明他何时安装了该应用，来到了登录页面，
有两个UITextField。
电子邮件 - ＆GT; UITextField - UIKeyboardTypeEmailAddress
passswd ---＆GT; UITextField安全类型
如果他点击电子邮件文本字段应用程序崩溃。 但如果他轻拍passwrd，那就正常了。
我已经完成了所有的可能性。
这是调用AppDelegate后得到的第一个视图，除了我分配的文本字段之外没有任何对象。此外，我无法输入凭据，无法通过此屏幕。
现在我得到他的崩溃报告

此UIViewController已设置UITextFieldDelegate
已实施textFieldShouldReturn:。
我不知道如何为他删除
结论至今
1）因为没有其他人可以复制这个问题我想，这家伙需要新安装该应用程序。
2）密码和电子邮件字段之间的区别是安全=是/否 所以，如果他可能使用不同的键盘。
3）是任何通知都在触发。
Textfield委托代码
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == self.username) {
DataObject *obj = [DataObject getInstance];
obj.firstlogin = true;
// whem return key pressed on username textfield, focus shifts to password textfield
[self.password becomeFirstResponder];
}
else if (theTextField == self.password) {
[self.password resignFirstResponder];
[self.view endEditing:YES];
self.apiConnection=nil;
[self login:self];
}
return YES;
}
