系统AlertVC文字居左


两种解决方案

1.runtime方法

alert可定制性更强

2.修改alertVC的subviews

支持:message居左;按钮变色等;

限制:message文字大小、message颜色定制


采用方法2的简单封装 - LBAlertVC

1.简易版 - 只支持一个按钮 (仅支持block)

[[LBAlertVC sharedInstance] showAlertVC_OneWithTitle:@"我是标题"
                                            message:@"我是message"
                                   messageAlignment:NSTextAlignmentLeft
                                         leftBtnStr:@"左按钮"
                                          leftBlock:^{
                                              NSLog(@"one - leftBtn click");
}];

2.基础版 - 支持两个按钮 (仅支持block)

[[LBAlertVC  sharedInstance]showAlertVC_BaseWithTitle:@"我是标题"
                                             message:@"我是message"
                                    messageAlignment:NSTextAlignmentLeft
                                          leftBtnStr:@"左按钮"
                                         rightBtnStr:@"我是右按钮"
                                           leftBlock:^{
                                               NSLog(@"base - leftBtn click");
                                           } rightBlock:^{
                                               NSLog(@"base - rightBtn click");
}];

3.基础版 - 支持两个按钮 (仅支持delegate)

@interface ViewController ()<LBAlertVCDelegate>

[[LBAlertVC sharedInstance] showAlertVC_WithDelegate_BaseWithTitle:@"我是标题"
                                                           message:message
                                                  messageAlignment:NSTextAlignmentLeft
                                                        leftBtnStr:@"左按钮"
                                                       rightBtnStr:@"我是右按钮"
                                                          delegate:self];
[LBAlertVC sharedInstance].tag = 10;

- (void)lbAlertVC:(UIAlertController *)alertVC buttonIndex:(NSInteger)buttonIndex{
    NSLog(@"tag=== %ld, buttonIndex=== %ld",[LBAlertVC sharedInstance].tag, buttonIndex);
}

4.高定制版 - 支持多元素定制 (支持Block、Delegate)

NSString *message = @"        你的银子”将支持快速取出(最快5秒到账),随时用钱随时提现,大大提高您的用钱效率。\n        现支持快速升级为“金子”(一键转购,预估“5日内”确认)。\n1.\n2.";
[[LBAlertVC sharedInstance] showAlertVCWithTitle:@"金子来了"
                                        message:message
                               messageAlignment:NSTextAlignmentLeft
                                     leftBtnStr:@"暂不升级"
                                   leftBtnStyle:UIAlertActionStyleDefault
                                   leftBtnColor:[UIColor greenColor]
                                    rightBtnStr:@"我要升级"
                                   leftBtnStyle:UIAlertActionStyleDestructive
                                  rightBtnColor:nil
                                          leftB:^{
                                              NSLog(@"leftBtn click");
                                          }
                                         rightB:^{
                                             NSLog(@"rightBtn click");
                                         }];
