修改后效果：

实现：
1.原理：通过扩展获取内容UILabel,修改其对应的对齐方式和换行方式
2.实现：(参考：https://stackoverflow.com/questions/25962559/uialertcontroller-text-alignment)
#import "UIAlertController+HuAlert.h"
@implementation UIAlertController (HuAlert)
@dynamic hu_titleLabel;
@dynamic hu_messageLabel;
-(UILabel *)hu_titleLabel{
return [self hu_viewArray:self.view][0];
}
-(UILabel *)hu_messageLabel{
return [self hu_viewArray:self.view][1];
}
- (NSArray *)hu_viewArray:(UIView *)rootView{
static NSArray *_subviews = nil;
_subviews = nil;
for (UIView *v in rootView.subviews) {
if (_subviews) {
break;
}
if ([v isKindOfClass:[UILabel class]]) {
_subviews = rootView.subviews;
return _subviews;
}
[self hu_viewArray:v];
}
return _subviews;
}
@end
3.使用：
+ (void)showAlertControllerAt:(UIViewController *)vc withMessage:(NSString *)message withTextAlignment:(NSTextAlignment)textAlignment{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
}];
alertController.hu_messageLabel.textAlignment = textAlignment;
alertController.hu_messageLabel.lineBreakMode = NSLineBreakByCharWrapping;
[alertController addAction:okAction];
[vc presentViewController:alertController animated:YES completion:nil];
}

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"输入学员卡号" message:nil preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}];
WS(weakSelf)
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
//
[alertController dismissViewControllerAnimated:YES completion:nil];
UITextField *textField = alertController.textFields[0];
weakSelf.perInfoModel.cadetCardNumber = textField.text;
[weakSelf tableViewFerfreshCell:indexPath.row section:indexPath.section];
[weakSelf updateServerCadetCardNumber:weakSelf.perInfoModel.cadetCardNumber];
}];
[alertController addAction:cancelAction];
[alertController addAction:okAction];
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.placeholder = @"国家继教网卡号";
}];
[self presentViewController:alertController animated:YES completion:nil];

UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"从照片库选择", @"拍照", nil];
sheet.delegate = self;
[sheet showInView:self.tableView];
[HuAlilog alilogWithBrowseActionWithPageId:@"30101"];

1.修改默认弹款布局
/**
* @brief 格式化弹出框消息内容，默认左对齐方式
* @param -offset 内容左边距
*/
+ (void)formatMessageContent:(UIAlertView *)alertView withOffset: (int)offset
{
BOOL bFirst = YES;
for (int i = 0; i < [alertView.subviews count]; i++) {
UIView *subs = [alertView.subviews objectAtIndex:i];
if ([subs isKindOfClass:[UILabel class]]) {
UILabel *tempLabel = (UILabel *)subs;
if (bFirst) {
tempLabel.font = [UIFont systemFontOfSize:20];
bFirst = NO;
} else{
float x = offset, y = tempLabel.frame.origin.y;
float width = tempLabel.frame.size.width - x;
float height = tempLabel.frame.size.height;
tempLabel.frame = CGRectMake(x, y, width, height);
tempLabel.textAlignment = UITextAlignmentLeft;
}
}
}
}

一. UIAlertController使用例子
- (void)quitButtonClick{
NSString *message = @"是否退出登录";
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
//
[HuAlilog alilogWithBrowseActionWithPageId:@"30804"];
}];
[alertController addAction:cancelAction];
[alertController addAction:okAction];
[self presentViewController:alertController animated:YES completion:nil];
}
二.UIAlertView使用例子
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请先绑定您的支付宝账户，资金将提现到您的支付宝账户" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"前往绑定", nil];
[alertView show];
UIAlertView * alert = [[UIAlertView alloc]initWithTitle:nil message:@"小护只接受原创课程提交哦，么么哒~" delegate:nil cancelButtonTitle:@"知道了" otherButtonTitles:nil, nil];
[alert show];
