之前一直在使用这个链接一直没问题,突然获取的版本号过于陈旧,没有及时更新(id为应用在App Store中id)
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?id=%@", @""]];
修改后的版本,可以及时更新,链接中添加cn
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@", @""]];
获取App Store版本号的方法
//appstore中的版本
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@", @""]];
NSError *error;
NSString * file = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];
if (error) {
return;
}
NSRange substr = [file rangeOfString:@"\"version\":\""];
if (substr.length == 0) {
return;
}
NSRange range1 = NSMakeRange(substr.location+substr.length,10);
NSRange substr2 =[file rangeOfString:@"\"" options:nil range:range1];
NSRange range2 = NSMakeRange(substr.location+substr.length, substr2.location-substr.location-substr.length);
NSString *newVersion =[file substringWithRange:range2];
NSLog(@"%@",newVersion);
dispatch_async(dispatch_get_main_queue(), ^{
}
});
});
