Codeing Show
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"提示" message:@"确认退出登录？" preferredStyle:(UIAlertControllerStyleAlert)];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"点击了Cancel");
[alertVC dismissViewControllerAnimated:YES completion:nil];
}];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"点击了OK");
[[NSUserDefaults standardUserDefaults] setObject:nil forKey:kLoginUserKey];
[alertVC dismissViewControllerAnimated:YES completion:nil];
}];
//修改title
NSMutableAttributedString *alertControllerStr = [[NSMutableAttributedString alloc] initWithString:@"提示"];
[alertControllerStr addAttribute:NSForegroundColorAttributeName value:kMainTextColor range:NSMakeRange(0, 2)];
[alertControllerStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:15] range:NSMakeRange(0, 2)];
[alertVC setValue:alertControllerStr forKey:@"attributedTitle"];
//修改message
NSMutableAttributedString *alertControllerMessageStr = [[NSMutableAttributedString alloc] initWithString:@"确认退出登录？"];
[alertControllerMessageStr addAttribute:NSForegroundColorAttributeName value:kSubTextColor range:NSRangeFromString(@"确认退出登录？")];
[alertControllerMessageStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:13] range:NSRangeFromString(@"确认退出登录？")];
[alertVC setValue:alertControllerMessageStr forKey:@"attributedMessage"];
//修改按钮字体颜色
[cancelAction setValue:kGreenColor forKey:@"titleTextColor"];
[okAction setValue:kGreenColor forKey:@"titleTextColor"];
[alertVC addAction:cancelAction];
[alertVC addAction:okAction];
[self presentViewController:alertVC animated:YES completion:nil];这里的kGreenColor 等是我自定义的颜色，换成自己的字体颜色即可
