我製作和應用程序讓人們下載內容，並且可以脫機訪問它，它喜歡目錄。但蘋果拒絕它，因爲它在iCloud烘烤我我正在做以下，但它似乎不工作。防止iCloud備份
Funciones.m
+ (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL {
const char* filePath = [[URL path] fileSystemRepresentation];
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
return result == 0;
}
Update.m
- (void)updateImg:(NSString *)tipo {
//tomamos el ultimo update
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSTimeInterval time = [defaults doubleForKey:@"lastUpdate"];
NSLog(@"%f", time);
CatalogoAppDelegate *app = [[UIApplication sharedApplication] delegate];
NSString *post = [NSString stringWithFormat:@"lastUpdate=%f", time];
NSData *postData = [post dataUsingEncoding:NSISOLatin1StringEncoding allowLossyConversion:NO];
NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
NSString *url = [NSString stringWithFormat:@"%@iPhone/update%@Img.php", app.serverUrl, tipo];
[urlRequest setURL:[NSURL URLWithString:url]];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:postData];
NSData *urlData;
NSURLResponse *response;
NSError *error;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
if(urlData) {
NSString *aStr = [[[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]autorelease];
//NSLog(@"%@: %@", tipo, aStr);
NSArray *temp = [aStr componentsSeparatedByString:@";"];
//Direccionl Local de la APP
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
for (int i=0; i<[temp count]; i++) {
NSString *tempImg = [NSString stringWithFormat:@"%@", [temp objectAtIndex:i]];
//NSLog(@"%@", tempImg);
//pedimos cada url
NSURL *tempURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@images/%@/%@", app.serverUrl, tipo, tempImg]];
//[Funciones addSkipBackupAttributeToItemAtURL:tempURL];
UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:tempURL]];
NSLog(@"%@images/%@/%@", app.serverUrl, tipo, tempImg);
NSString *pngFilePath = [NSString stringWithFormat:@"%@/%@", docDir, tempImg];
NSData *data1 = [NSData dataWithData:UIImagePNGRepresentation(image)];
[data1 writeToFile:pngFilePath atomically:YES];
NSURL *backUrl = [NSURL fileURLWithPath:pngFilePath];
[Funciones addSkipBackupAttributeToItemAtURL:backUrl];
}
}
[self performSelectorInBackground:@selector(finUpdate) withObject:nil];
}
任何想法，我做錯了什麼？
感謝
嗨@Jim那個方法它返回True。我檢查它提供的每一個網址。但我的問題是我需要在那部分或下載它之前添加哪部分？ – Edig
你確定嗎？你提供的代碼根本不檢查返回值。 – Jim
嗨@Jim不，我不檢查它，但我調試它，它返回1 =真。但是你認爲這個實現是否正確？ – Edig
