我开发了应用程序，我从服务器下载图像并在UITableView
应用拒绝原因
特别是，我们发现在启动和/或内容下载时，您的应用存储了2.67 MB。要检查应用存储的数据量：
iOS数据存储指南指出，只有用户使用您的应用创建的内容（例如文档，新文件，编辑等）才能由iCloud备份。
您的应用使用的临时文件只应存储在/ tmp目录中;请记得在用户退出应用程序时删除存储在此位置的文件。
可以重新创建但必须保持应用程序正常运行的数据 - 或者因为客户希望它可供脱机使用 - 应标记为“不备份”属性。对于NSURL对象，请添加NSURLIsExcludedFromBackupKey属性以防止备份相应的文件。对于CFURLRef对象，请使用相应的kCFURLIsExcludedFromBackupKey属性。
这是我的代码显示我如何从服务器下载数据并显示它：
- (BOOL)fileExist:(NSString *)name //Check's whether image Exists in Doc Dir.
{
BOOL theSuccess;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:name];
NSFileManager *fileManager = [NSFileManager defaultManager];
theSuccess = [fileManager fileExistsAtPath:fullPath];
if(theSuccess){
return YES;
} else {
return NO;
}
}
- (void)downloadFile:(NSString *)urlFile withName:(NSString *)fileName //If image not exists it will download image.
{
NSString *trimmedString = [urlFile stringByTrimmingCharactersInSet:
[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([trimmedString length]>0)
{
HTTPEaterResponse *response = [HTTPEater get:[NSString stringWithFormat:@"%@",trimmedString]];
if ([response isSuccessful])
{
[self saveImage:[[UIImage alloc] initWithData:[response body]] withName:fileName];
}
}
}
-(void)saveImage:(UIImage *)image withName:(NSString *)name //After downloading image it stores in Doc dir.
{
NSString *pngPath = [NSHomeDirectory() stringByAppendingPathComponent:[@"Documents/" stringByAppendingString:name]];
[UIImagePNGRepresentation(image) writeToFile:pngPath atomically:YES];
}
- (UIImage *)loadImage:(NSString *)name //Used for displaying.
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:name];
UIImage *img = [UIImage imageWithContentsOfFile:fullPath];
return img;
}
显示数据的代码：
- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
...
if ([dicImages valueForKey:[[msg_array objectAtIndex:indexPath.row] valueForKey:@"merchantimage"]])
{
cell.MerchntLogo.image=[dicImages valueForKey:[[msg_array objectAtIndex:indexPath.row] valueForKey:@"merchantimage"]];
}
else
{
if (!isDragging_msg && !isDecliring_msg)
{
if ([[[msg_array objectAtIndex:indexPath.row] valueForKey:@"merchantimage"] length]!=0)
{
[dicImages setObject:[UIImage imageNamed:@"rowDefault.png"] forKey:[[msg_array objectAtIndex:indexPath.row] valueForKey:@"merchantimage"]];
[self performSelectorInBackground:@selector(downloadImage_3:) withObject:indexPath];
}
}
else
{
cell.MerchntLogo.image=[UIImage imageNamed:@"rowDefault.png"];
}
}
...
}
-(void)downloadImage_3:(NSIndexPath *)path{
if ([[[msg_array objectAtIndex:path.row] valueForKey:@"merchantimage"] length]!=0)
{
NSString *str=[[msg_array objectAtIndex:path.row] valueForKey:@"merchantimage"];
UIImage *img = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:str]]];
[dicImages setObject:img forKey:[[msg_array objectAtIndex:path.row] valueForKey:@"merchantimage"]];
[tblProdDetail performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];
}
}
请帮我弄清楚我的应用被拒绝的原因，以及我可以采取哪些措施来解决问题。

您的应用显然违反了Apple的数据存储指南，该指南规定只有用户生成的数据应存储在Documents文件夹中。此数据会自动备份到iCloud，并且违反5GB上限。如果应用程序在此文件夹中存储了太多数据（如Apple所认为的那样），则可以从App Store拒绝该数据。
您的数据不会被归类为用户生成的内容，并且超过2 MB这是限制。
您可以通过此处引用来阻止备份数据。

你需要做他们所说的话。标记文件
只需添加didFinishLaunching
即可NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
documentsDirectory = [paths objectAtIndex:0];
[self applyAttributes:documentsDirectory];
然后实现这个方法
#pragma mark - Application's Documents directory
// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory
{
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}
-(void)applyAttributes:(NSString *)folderPath
{
NSArray *filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];
NSEnumerator *filesEnumerator = [filesArray objectEnumerator];
NSString *fileName;
while (fileName = [filesEnumerator nextObject]) {
// NSLog(@"apply to %@", [[NSURL fileURLWithPath:[folderPath stringByAppendingPathComponent:fileName]] path]);
if([self addSkipBackupAttributeToItemAtURL:[NSURL fileURLWithPath:[folderPath stringByAppendingPathComponent:fileName]]])
{
//NSLog(@"success applying");
}
//NSDictionary *fileDictionary = [[NSFileManager defaultManager] attributesOfItemAtPath:[folderPath stringByAppendingPathComponent:fileName] error:nil];
//fileSize += [fileDictionary fileSize];
}
}
- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
if([[NSFileManager defaultManager] fileExistsAtPath: [URL path]])
{
NSError *error = nil;
BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
forKey: NSURLIsExcludedFromBackupKey error: &error];
if(!success){
NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
}
return success;
}
return NO;
}

使用此方法绕过在iCloud上存储数据
将文件路径传递给此方法
- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
const char* filePath = [[URL path] fileSystemRepresentation];
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
BOOL result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
return result;
}
