众所周知，当伟大的iOS7系统发布后，表扬的一堆、谩骂的也一片，而对于我们程序员来说最关心的莫过于低版本系统上的程序在搞版本系统上的兼容性问题了。
在iOS6.1几之前，当我们想要做一些提醒用户或临时获取一些数据时，通常会弹出一个模态试图，给予用户提醒，而最常见的做法莫过于直接用UIAlertView添加控件或继承UIAlertView，然后添加自己想要的控件，如：在执行网络连接 &下载等耗时任务时我们会弹出一个view &然后显示一个指示器，具体做法：
- (IBAction)showTraditionAlert:(id)sender {
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"正在下载....." message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.delegate =
[alertView show];
#pragma mark -- UIAlertViewDelegate
//实现代理增加网络指示器
- (void)willPresentAlertView:(UIAlertView *)alertV{
indicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
indicator.frame = CGRectMake(110, 20, 50, 50);
[alertView addSubview:indicator];
[indicator startAnimating];
[indicator release];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
[indicator stopAnimating];
但上面的做法到了iOS7上就没有用了 ，你自己所添加的控件根本显示不出来，也就是说在iOS7上不允许我们更改系统的UIAlertView了（至少目前是这样 beta3版本），我想大家肯定也遇到了这样的问题，那现在改怎么半呢？ 可以采用UIWindow的方式实现具体做法网上很多，我比较懒 随便写了点

UIAlertView及UIActionSheet在ios8中被放弃,其功能将完全由UIAlertController代替:
1.Alert用法
&UIAlertController *alert = [UIAlertController
alertControllerWithTitle:@&This is Title&
&& & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & & &
message:@&This is message&
& & & & & & & & & & & & & & & & & & & & & & & & & & & & & &
preferredStyle:UIAlertControllerStyleAlert];
& & [alert addAction:[UIAlertAction
actionWithTitle:@&Action 1 (Default Style)&
& & & & & & & & & & & & & & & & & & & & & & & style:UIAlertActionStyleDefault
& & & & & & & & & & & & & & & & & & & & & & handler:^(UIAlertAction *action) {
& & & & & & & & & & & & & & & & & & & & & & & & NSLog(@&Action 1 Handler Called&);
& & & & & & & & & & & & & & & & & & & & & & }]];
& & [alert addAction:[UIAlertAction
actionWithTitle:@&Action 2 (Cancel Style)&
& & & & & & & & & & & & & & & & & & & & & & & style:UIAlertActionStyleCancel
& & & & & & & & & & & & & & & & & & & & & & handler:^(UIAlertAction *action) {
& & & & & & & & & & & & & & & & & & & & & & & & NSLog(@&Action 2 Handler Called&);
& & & & & & & & & & & & & & & & & & & & & & }]];
& & [alert addAction:[UIAlertAction
actionWithTitle:@&Action 3 (Destructive Style)&
& & & & & & & & & & & & & & & & & & & & & & & style:UIAlertActionStyleDestructive
& & & & & & & & & & & & & & & & & & & & & & handler:^(UIAlertAction *action) {
& & & & & & & & & & & & & & & & & & & & & & & & NSLog(@&Action 3 Handler Called&);
& & & & & & & & & & & & & & & & & & & & & & }]];
& & [alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
& & & & UITextField * tf = [[UITextField
alloc]initWithFrame:CGRectMake(0,
presentViewController:alert animated:YES
completion:nil];
2,actionsheet用法
&UIAlertController *alertController = [UIAlertController
alertControllerWithTitle:nil
message:nil
preferredStyle:UIAlertControllerStyleActionSheet];
& & [alertController addAction:[UIAlertAction
actionWithTitle:@&111&
& & & & & & & & & & & & & & & & & & & & & & & & & & & &
style:UIAlertActionStyleDefault
& & & & & & & & & & & & & & & & & & & & & & & & & & &
handler:^(UIAlertAction *action) {
& & & & & & & & & & & & & & & & & & & & & & & & & & & & &
NSLog(@&111&);
& & & & & & & & & & & & & & & & & & & & & & & & & & & }]];
& & [alertController addAction:[UIAlertAction
actionWithTitle:@&222&
& & & & & & & & & & & & & & & & & & & & & & & & & & & &
style:UIAlertActionStyleCancel
& & & & & & & & & & & & & & & & & & & & & & & & & & &
handler:^(UIAlertAction *action) {
& & & & & & & & & & & & & & & & & & & & & & & & & & & & &
NSLog(@&222&);
& & & & & & & & & & & & & & & & & & & & & & & & & & & }]];
presentViewController:alertController animated:YES
completion:nil];
版本判断语句
#define iOS(version) (([[[UIDevice currentDevice] systemVersion] intValue] &= version)?1:0)
可进行判断添加alertController或是aletView和actionsheet
3.新的问题,当在ios8下做好判断之后,返回ios7或ios6运行xcode,报错-------
原因:UIAlertController只在ios8下的框架里由此文件,ios7及以下版本没有,但编译的时候还是会进行编译(虽然运行时不走这部分代码)
解决方法:编译时进行判断,只有在ios8SDK下编译此部分
#if __IPHONE_OS_VERSION_MAX_ALLOWED &= 80000
& & & & & & &&alertcontroller相关代码&
重新运行xcode,ok,可以正常运行了.

看有没有实现代理方法，而且你用的是delegate:self 你的程序应该在这部分有警告吧
