iOS 11自定义UIAlertView不呈现罚款

Question

所以我有和自定义UIAlertView应用程序（通过自定义我的意思是在底部以编程方式添加UILabel）。它在iOS < 11上运行得很好，但是在iOS 11中它失败了。因此，在iOS 10上它工作正常（左），但在iOS 11（右）中失败，使用相同的代码当然

这是我用来制作自定义UAlertView的代码。有任何想法吗？

SessionManager *sessionMgr = [SessionManager sharedManager]; 
NSString *saludoStr = [NSString stringWithFormat:@"¡Bienvenido %@!",self.datosPersonalesResponse.nombre]; 
NSString *mailStr = [sessionMgr getUserEmail]; 
NSString *mensajeStr = [NSString stringWithFormat:@"Te hemos enviado un email de \nactivación de cuenta a: \n\n%@\n\nActivá tu cuenta para recibir alertas,\n avisos recomendados y postularte a \nempleos.\n",mailStr]; 

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:saludoStr message:@"" delegate:self cancelButtonTitle:@"Cerrar" otherButtonTitles:@"No lo recibí", nil]; 
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 100)]; 
lbl.numberOfLines= 0; 

[lbl setFont:[UIFont fontWithName:@"OpenSans" size:13]]; 
[lbl setTextColor:[UIColor colorWithRed:146/255.0f green:146/255.0f blue:146/255.0f alpha:1.0]]; 

NSMutableAttributedString *attributedStr = [[NSMutableAttributedString alloc] initWithString:mensajeStr]; 
[attributedStr addAttribute:NSFontAttributeName 
         value:[UIFont fontWithName:@"OpenSans-Semibold" size:16] 
         range:NSMakeRange(56,[mailStr length])]; 

[attributedStr addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(56,[mailStr length])]; 

lbl.attributedText = attributedStr; 
lbl.textAlignment = NSTextAlignmentCenter; 
[alert setValue:lbl forKey:@"accessoryView"]; 
[alert show];
