我正在使用Parse.com檢索我的數據。我想通過pf查詢從解析中檢索我的圖像,但是我的方法無法正常工作。我的UIImageView沒有任何位置。這裏是我的代碼:如何通過iOS查詢從Parse.com中檢索圖像?
PFQuery *query = [PFQuery queryWithClassName:@"Class"];
[query whereKey:@"Yes or No" equalTo:[NSNumber numberWithBool:YES]];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
// The find succeeded.
NSLog(@"Successfully retrieved %d scores.", objects.count);
for (int i = 0; i < objects.count; i++) {
object = [objects objectAtIndex:i];
NSString *Property1 = [object objectForKey:@"Property1"];
__block UIImage *MyPicture = [[UIImage alloc]init];
PFFile *imageFile = [object objectForKey:@"Resimler"];
[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error){
if (!error) {
MyPicture = [UIImage imageWithData:data];
}
}];
aClass *AC = [[aClass alloc]initWithProperty:Propert1 Picture:MyPicture];
[self.MyArray addObject:AC];
}
}
} else {
// Log details of the failure
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
}];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
MyViewViewCell *cell = (MyViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Cell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
aClass *mC = [self.MyArray objectAtIndex:indexPath.row];
cell.Label.text = mC.Property;
cell.myImage.image = mC.Picture;
return cell;
}
編輯:
At aClass.h
@interface aClass : NSObject
@property(strong)NSString *Property;
@property(strong)UIImage *Resim;
-(id)initWithProperty:(NSString *)aProperty Picture:(UIImage *)aPicture ;
@end
at aClass.m
@implementation Mekan
@synthesize Property, Picture;
-(id)initWithMekanIsmi:(NSString *)aProperty Picture:(UIImage *)aPicture{
self=[super init];
if(self){
self.Property = aProperty;
self.Picture = aPicture;
}
return self;
}
@end
我知道這是怎麼樣的一個質量代碼,但我必須寫這些代碼來說明其中i分配MYIMAGE。所以,你可以問你不懂
我沒有看到你的代碼中你指定你的UIImageView。 –
考慮添加類似'NSLog(@「無錯誤」);'在你分配'MyPicture = [UIImage imageWithData:data]'的上方,'以確保正在觸發。 –
我在NSLog沒有得到錯誤消息,我會嘗試添加我分配UIImageView的位置。 – user2393702
