我試圖將NSArray保存到包含元素或對象的現有MutableArray。NSCFArray長度錯誤iOS
我成功地將數組添加到了mutablemarray中,並記錄了數組並記錄了它的數組數目。一切似乎都沒有問題,直到我想將5個保存的值添加到我的UITableView
。
我的應用程序崩潰了一個奇怪的例外。我已經嘗試了一切,但似乎沒有任何工作。
我不知道該在哪裏繼續調試。
保存在應用程序開始的首選項。
for (NSMutableDictionary *defineXMLData in getSpecialsAuth) {
NSArray * imageUrl = [defineXMLData objectForKey:@"imageUrl"];
[specialsimageUrlArray addObject: imageUrl];
[specialsimageUrlArray addObject: test];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:specialsimageUrlArray forKey:@"specialsImageUrlArray"];
}
SpecialsViewController.m
-(void)viewDidLoad {
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
self.specialsArray = [prefs arrayForKey:@"specialsImageUrlArray"];
NSMutableArray *specialsimageUrlArray =[[NSMutableArray alloc]init];
test = [NSArray arrayWithObjects:@"http://dev.wigroup.co/bells/cvs_images/bells3.jpg", nil];
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSData *imageData= [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[self.specialsArray objectAtIndex:indexPath.row]]];
UIImageView *imageViewForCell = [[UIImageView alloc]initWithFrame:CGRectMake(3,3,30,30)];
imageViewForCell.image = [UIImage imageWithData:imageData];
[imv addSubview:imageViewForCell];
}
的NSLog

可以添加此方法檢查對象的類型? [SpecialsDetailViewController downloadSpecialImage] –
'specialsimageUrlArray'的類型是什麼? –
我懷疑這個消息('length')最初是要發送給一個字符串的(看起來像某種URL解析給我的東西),但由於某種原因(內存損壞?)它已經發送到一個數組。 – 2014-01-21 14:07:35
