我的应用程序在通过 Xcode 部署到我的 iPhone 时似乎工作正常，但是现在当我下载它时它在应用商店中，它崩溃了。它一定对苹果有用，因为它永远不会通过审查？？？？
我尝试过其他手机，但它们也崩溃了。通过查看崩溃日志，下面的代码是值得关注的领域。
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
// Do a tasks in the background
library = [[ALAssetsLibrary alloc] init];
NSMutableArray *itemFileName = [[NSMutableArray alloc] init];
for (Item *it in tag.Items) {
[itemFileName addObject:it.name];
}
void (^assetEnumerator)( ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *asset, NSUInteger index, BOOL *stop) {
if(asset != NULL && [asset valueForProperty:ALAssetPropertyType] == ALAssetTypePhoto) {
ALAssetRepresentation *rep = [asset defaultRepresentation];
NSString *fileName = [rep filename];
if ([itemFileName containsObject:fileName]) {
AssetView *assetView = [[AssetView alloc] initWithAsset:asset];
assetView.delegate = self;
assetView.fileName = fileName;
//assetView.index = counter;
[self.assetViews addObject:assetView];
//NSLog(@"%i",index);
}
}
};
void (^assetGroupEnumerator)( ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop) {
if(group != nil) {
[group enumerateAssetsUsingBlock:assetEnumerator];
}
else{
//[self performSelectorOnMainThread:@selector(reloadTableView) withObject:nil waitUntilDone:YES];
// Hide the HUD in the main tread
dispatch_async(dispatch_get_main_queue(), ^{
[self reloadTableView];
[MBProgressHUD hideHUDForView:self.navigationController.view animated:YES];
[self loadImageTags];
if([self.assetViews count] != [tag.Items count]){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Info"
message:@"Some items have been deleted from the device. If none remain for this tag it will be deleted."
delegate:self
cancelButtonTitle:nil
otherButtonTitles: @"OK", nil];
[alert show];
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
hud.labelText = @"Cleaning...";
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
[self clearupOrphanedItems];
dispatch_async(dispatch_get_main_queue(), ^{
[MBProgressHUD hideHUDForView:self.navigationController.view animated:YES];
});
});
}
});
}
};
// Group Enumerator Failure Block
void (^assetGroupEnumberatorFailure)(NSError *) = ^(NSError *error) {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Album Error: %@ - %@", [error localizedDescription], [error localizedRecoverySuggestion]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
NSLog(@"A problem occured %@", [error description]);
};
// Enumerate Albums
[library enumerateGroupsWithTypes:ALAssetsGroupAll
usingBlock:assetGroupEnumerator
failureBlock:assetGroupEnumberatorFailure]; //HERE IS WHERE IT DIES!!!
});
我不确定问题是否是由于在块内实例化 ALAssetLibrary 造成的，因为它可以在调试期间正常工作，甚至只是通过 Xcode 部署到电话
任何人都可以为我阐明这一点吗？
