我有一个包含图像数据的SQLite数据库作为BLOB,我使用以下代码来设置对象的属性,但是我遇到了数据的主要内存问题,特别是在data
和w.wineImage
个对象,即使看起来我正在正确释放所有内容......
if(sqlite3_prepare_v2(database, sql, -1, &selectstmt, NULL) == SQLITE_OK) {
while(sqlite3_step(selectstmt) == SQLITE_ROW) {
Wine *w = [[Wine alloc] init];
w.wineId = sqlite3_column_int(selectstmt, 0);
w.wineName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 1)];
NSData *data = [[NSData alloc] initWithBytes:sqlite3_column_blob(selectstmt, 2) length:sqlite3_column_bytes(selectstmt, 2)];
if([data length] < 10){
UIImage *noImage = [UIImage imageNamed:@"no_image.png"];
w.wineImage = noImage;
[noImage release];
[data release];
} else {
UIImage *wineBottle = [[UIImage alloc] initWithData:data];
w.wineImage = wineBottle;
[wineBottle release];
[data release];
}
w.price = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 3)];
[wineArray addObject:w];
//w=nil;
[w release];
}
sqlite3_close(database);
答案 0 :(得分:0)
您正在发布noImage,但是您已经从已经自动释放的imageNamed创建了它。
我不知道这是否有助于解决您的问题,但您绝对不应该这样做:)
