它不会每次都发生,但随机 insertRowsAtIndexPaths: 在 tableviews endUpdates 上使我的应用程序崩溃。这是代码。
NSURLRequest *request1 = [NSURLRequest requestWithURL:url1];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request1 success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
dispatch_async(dispatch_get_main_queue(), ^{
self.contentArray = [NSMutableArray arrayWithArray:JSON];
NSMutableArray *indexArray = [NSMutableArray array];
[self.contentArray enumerateObjectsUsingBlock:^(id anObject, NSUInteger idx, BOOL *stop) {
[indexArray addObject:[NSIndexPath indexPathForRow:idx inSection:0]];
}];
[self.mainTable beginUpdates];
[self.mainTable insertRowsAtIndexPaths:indexArray withRowAnimation:UITableViewRowAnimationAutomatic];
[self.mainTable endUpdates];
self.mainTable.tableFooterView = [self buildLoadingView];
self.mainTable.contentInset = UIEdgeInsetsMake(64.0, 0.0, 80.0, 0.0);
});
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){
NSLog(@"%@", JSON);
}];
[operation start];
任何帮助深表感谢!提前致谢!
