MRCLoginViewController.m 66行判断有点问题

[liuaaaddxiaoer]

@weakify(self)
[[self
rac_signalForSelector:@selector(textFieldShouldReturn:)
fromProtocol:@protocol(UITextFieldDelegate)]
subscribeNext:^(RACTuple *tuple) {
@strongify(self)
if (tuple.first == self.passwordTextField && self.loginButton.enabled) {
[self.viewModel.loginCommand execute:nil];
}else {
NSLog(@"提示用户要输入账号或密码信息");
}
}];
