for (QHBossCurrencyListInfoModel *model in dataArray) {
        if ([model.currency isEqualToString:@"BTC"]) {
            [dataArray removeObject:model];
        }
}

导致会奔溃，因为改变了遍历的数组

正确的写法如下

NSMutableArray *list = [NSMutableArray arrayWithArray:dataArray];
for (QHBossCurrencyListInfoModel *model in list) {
    if ([model.currency isEqualToString:@"BTC"]) {
            [dataArray removeObject:model];
    }
 }
