1、SignInViewController.h

#import <UIKit/UIKit.h>@interface SignInViewController : UIViewController<UIAlertViewDelegate>{    UIAlertView *remoteAlertView;}@end

2、SignInViewController.m

#import "SignInViewController.h"@interface SignIniewController ()@end@implementation SignInViewController-(void)dealloc{    if (remoteAlertView) {        [remoteAlertView release];    }    [super dealloc];}// 方法內：    // 遠程webservice方法    RemoteLogic *remoteLogic = [[RemoteLogic alloc] init];    // 啟動動畫    [self remoteAnimation:@"正在擷取伺服器時間, 請稍候..."];    // 非同步載入資料    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{        // 擷取webservice資料        delegate.serverTime = remoteLogic.getServerTime;        dispatch_async(dispatch_get_main_queue(), ^{            // 關閉動畫            [remoteAlertView dismissWithClickedButtonIndex:0 animated:YES];            // 擷取webservice資料後操作 do something        });    });#pragma mark - Animation-(void)remoteAnimation:(NSString *)message{    if (remoteAlertView) {        [remoteAlertView release];    }    remoteAlertView =  [[UIAlertView alloc] initWithTitle:@"提示" message:message delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil ];    UIActivityIndicatorView *aiView = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125.0, 80.0, 30.0, 30.0)];    aiView.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;    //check if os version is 7 or above. ios7.0及以上UIAlertView棄用了addSubview方法    if ([[[UIDevice currentDevice] systemVersion] compare:@"7.0"] != NSOrderedAscending) {        [remoteAlertView setValue:aiView forKey:@"accessoryView"];    }else{        [remoteAlertView addSubview:aiView];    }    [remoteAlertView show];    [aiView startAnimating];    [aiView release];}
