iOS应用版本更新

在#import "AppDelegate.h" 文件中的application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中调用检测结果

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    //ios应用版本更新

    [selfVersionClick];

    returnYES;

}

获得发布版本的Version

//更新实现方法

-(void)VersionClick{

//获取发布版本的Version,id替换成自己应用的id

    NSString *string = [NSStringstringWithContentsOfURL:[NSURLURLWithString:@"http://itunes.apple.com/lookup?id=662004496"]encoding:NSUTF8StringEncodingerror:nil];

    if (string !=nil && [stringlength]>0 && [stringrangeOfString:@"version"].length==7) {

        [selfcheckAppUpdata:string];

    }

}

比较当前版本与新上线版本做比较
