首先,我添加了一些需要从一个类文件中的不同ViewControllers调用的函数。对于这些功能,我将SVProgressHUD添加为预处理并在所有进程完成后关闭。 SVProgressHUD在进程开始之前正确显示。但经过一段时间后,SVProgressHUD根本就不会被解雇。请让我知道如何解决这个问题。
我在所有流程中添加[SVProgressHUD dismiss];
已完成。但从未被解雇。
common.m
- (NSDictionary *) loadBlahClass:(NSString *)paramUserId {
[SVProgressHUD showWithStatus:@"Loading Cards..."];
__block NSDictionary *jsonResponse;
dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.completionQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.responseSerializer.acceptableContentTypes setByAddingObject:@"application/json"];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSString *urlStr = [NSString stringWithFormat:@"MY_URL"];
[manager GET:urlStr parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSString *jsonString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
[SVProgressHUD dismiss];
dispatch_semaphore_signal(semaphore);
}
failure:
^(AFHTTPRequestOperation *operation, NSError *error) {
[SVProgressHUD dismiss];
[self showAlert:APP_NAME alertMessage:[error localizedDescription]];
dispatch_semaphore_signal(semaphore);
}];
[SVProgressHUD dismiss];
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
return jsonResponse;
}
testViewController.m
_allTableData = [[NSMutableArray alloc]init];
NSDictionary *jsonResponse = [commClass loadBlahClass:strUserId];
NSNumber *status = [jsonResponse valueForKey:@"Success"];
NSString *message = [jsonResponse valueForKey:@"Message"];
NSArray *dataArray = [jsonResponse valueForKey:@"lstCC"];
if([status intValue] == 1) {
for(int i=0; i<[dataArray count]; i++) {
//working .......
}
[_ccTable reloadData];
[SVProgressHUD dismiss];
} else {
[commClass showAlert:APP_NAME alertMessage:message];
[SVProgressHUD dismiss];
}
答案 0 :(得分:0)
我找到了答案。这样的事情。
[SVProgressHUD show];
__block BOOL result;
dispatch_async(queue, ^{
result = [self autanticate];
NSLog(@"autantication result = %d", result);
result = [self getCSRFToken];
NSLog(@"Login success result = %d", result);
dispatch_async(dispatch_get_main_queue(), ^{
[SVProgressHUD dismiss];
})
});
