AlertViewController的自定義文字顏色

alertController有時有顯示的太單一吗蚌，我們需要給他自定義顏色布朦，這里我用的是NSMutableAttributedString囤萤，可以設(shè)置成自己喜歡的顏色和樣式。是趴。涛舍。

?UIAlertController *alert =[UIAlertController alertControllerWithTitle:@"立即支付" message:@"您的應(yīng)付金額為：￥58000" preferredStyle:UIAlertControllerStyleAlert];

? ? // 使用富文本來改變alert的title字體大小和顏色

? ? NSMutableAttributedString *title =[[NSMutableAttributedString alloc]initWithString:@"立即支付"];

? ? [title addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:17]range:NSMakeRange(0,4)];

? ? [title addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1.0]range:NSMakeRange(0,4)];

? ? [alert setValue:title forKey:@"attributedTitle"];

? ? // 使用富文本來改變alert的message字體大小和顏色

? ? // NSMakeRange(0, 14) 代表:從0位置開始 14個字符

? ? NSMutableAttributedString *message =[[NSMutableAttributedString alloc]initWithString:@"您的應(yīng)付金額為：￥58000"];

? ? [message addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:16]range:NSMakeRange(0,14)];

? ? [message addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:250/255.0 green:84/255.0 blue:88/255.0 alpha:1.0]range:NSMakeRange(8,6)];

? ? [alert setValue:message forKey:@"attributedMessage"];

? ? UIAlertAction *cancelAction =[UIAlertAction actionWithTitle:@"立即代付" style:UIAlertActionStyleDefault handler:^(UIAlertAction *_Nonnullaction){

? ? ? ? [selfnowPay];

? ? }];

//? ? //設(shè)置按鈕的title顏色

? ? [cancelAction setValue:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1.0]forKey:@"titleTextColor"];

//

//? ? //設(shè)置按鈕的title的對齊方式

? ? [cancelAction setValue:[NSNumber numberWithInteger:NSTextAlignmentCenter]forKey:@"titleTextAlignment"];

//

? ? UIAlertAction *okAction =[UIAlertAction actionWithTitle:@"朋友支付" style:UIAlertActionStyleDefault handler:^(UIAlertAction *_Nonnullaction){

? ? ? ? [selffriendPay];

? ? }];

? ? // 設(shè)置按鈕的title顏色

? ? [okAction setValue:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1.0]forKey:@"titleTextColor"];

//

//? ? //設(shè)置按鈕的title的對齊方式

? ? [okAction setValue:[NSNumber numberWithInteger:NSTextAlignmentCenter]forKey:@"titleTextAlignment"];

? ? [alert addAction:okAction];

? ? [alert addAction:cancelAction];

?? ?[selfpresentViewController:alert animated:YEScompletion:nil];

}

//朋友代付

-(void)friendPay{

}

//立即支付

-(void)nowPay{

}
