我們的應用程序中有一項功能,用戶可以從該攝像頭拍攝多張照片。所有這些照片都添加到NSMuteArray對象,並在用戶點擊保存按鈕後發送到服務器。將多個圖像發送到服務器的問題 - iphone應用程序

目前這個過程不適用於我們,每當用戶點擊保存,應用程序崩潰。我們使用下面的代碼來添加元素NSMuteArray

UIImage *img=[info objectForKey:UIImagePickerControllerOriginalImage]; 

self.picData=UIImageJPEGRepresentation([[self scaleAndRotateImage:img] fixOrientation], 1.0); 

[self.addPhotosBtn setImage:[UIImage imageWithData:self.picData] forState:UIControlStateNormal]; 
[self.addPhotosBtn setImage:[UIImage imageWithData:self.picData] forState:UIControlStateHighlighted]; 
[self.addPhotosBtn setImage:[UIImage imageWithData:self.picData] forState:UIControlStateHighlighted]; 



NSString *ImgData =[[NSString alloc] initWithData:self.picData encoding:NSUTF8StringEncoding]; 

if (appDelegate.selectedPhotos) { 
    [self.selectedPhotos addObject:self.picData]; 
    [appDelegate.selectedPhotos addObject:self.picData]; 
}else{ 
    appDelegate.selectedPhotos=[NSMutableArray arrayWithCapacity:0]; 
    self.selectedPhotos=[NSMutableArray arrayWithCapacity:0];  
} 

而且,這裏是同時節省我們使用的代碼..

NSDateFormatter *df1=[[NSDateFormatter alloc]init]; 
[df1 setDateFormat:@"MMMM dd, yyyy"]; 
NSDate *dd=[df1 dateFromString:self.date.text]; 
[df1 setDateFormat:@"yyyy-MM-dd"]; 


NSDictionary *data=[NSDictionary dictionaryWithObjectsAndKeys: 
        //appDelegate.selectedPhotos,@"photos", 
        [appDelegate.allcatches objectForKey:@"catches"],@"allcatches", 
        [appDelegate.selectedPlace objectForKey:@"id"],@"currentplace", 
        [df1 stringFromDate:dd ],@"currentdate", 
        [self.description.text isEqualToString:@""] ? @"NULL" : self.description.text,@"description", 
        self.fbBtn.selected ? @"Y":@"N",@"facebookshare", 
        self.twBtn.selected ? @"Y":@"N",@"twittershare", 
        appDelegate.selectedPhotos,@"photos", 
        nil]; 
[appDelegate performSelectorInBackground:@selector(uploadPostDataToServer:) withObject:data]; 

誰能幫我們解決這一問題?

謝謝你的留言...我們只解析一些xml文件... – 2012-04-20 09:59:04

所以你可以發佈上傳進度的源代碼 – CarlJ 2012-04-20 10:00:17
