小编Ada*_*ush的帖子

我基本上是想这样做;

// Catch the true/false flag and convert to BOOL value for server
NSString *on = [prefs objectForKey:@"published"];
BOOL flag = TRUE;
if ([on isEqualToString:@"true"]) 
{
    flag = TRUE;
} 
else 
{
    flag = FALSE;
}

NSArray *objects = [NSArray arrayWithObjects:body, flag, user_token, request_token, deviceID, api_user, nil];
NSArray *keys = [NSArray arrayWithObjects:@"selections", @"published", @"user_token", @"request_token", @"device_id", @"api_user", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

哪个检查prefs是否为true,如果是,则转换为BOOL值为true等.

然而它崩溃说它缺少对象的对象数量.

这样做有什么帮助吗？

我正在做一个小计算,但它总是返回0 ..

    int totalBothTeams = [prefs integerForKey:@"totalTimeBothTeams"];
    int someCalculation = (totalBetween / totalBothTeams) * 100;

    NSLog(@"Time: %i", someCalculation);

有任何想法吗？

救命!我已经用这个问题把头发拉了1个小时了.

我正在我的.h文件中创建一个数组

    @interface LeftMenuViewController : UIViewController <UITableViewDataSource, UITabBarControllerDelegate>

@property (strong, nonatomic) MKNetworkOperation *myNetworkOperation;
@property (strong, nonatomic) NSArray *listOfClubsArray;

@end

然后我从JSON中的API调用中提取项目列表

///////////////////////////////////////////
#pragma mark Retreive List of Clubs / Teams
///////////////////////////////////////////

- (void)getListOfClubs {

    // Because we have a success from login auth we will now make a seperate call to gather club details

    self.myNetworkOperation = [app.teamManagerWrapper deviceID:@"adam" userToken:@"sdfdfgf" onCompletion:^(NSDictionary *result) {

        NSDictionary *data2 = [result objectForKey:@"data"];

        self.listOfClubsArray = [data2 objectForKey:@"user_clubs"];

        [self.tableView reloadData];

    } onError:^(NSError *error) {

        // error none

    }]; …
