我有一个初始化背包对象数组的函数，背包对象的属性是正，负和中性属性，它们都是NSStrings。问题是，当我初始化属性的值时，相同的值重复两次（当我记录它的值时）
代码：
#pragma mark - Creating Backpack Icons
-(NSArray *)createBackpackIcons:(NSArray *)groups usingItemGroups:(NSArray *)items
{
NSMutableArray *backpackItems = [[NSMutableArray alloc] init];
for (NSInteger i = 0; i < _groups.count; i++) {
Group *group = _groups[i];
NSString *defindex1 = [NSString stringWithFormat:@"%@", group.defindex];
for (NSInteger j = 0; j < _itemGroups.count; j++)
{
Item *item = _itemGroups[j];
NSString *defindex2 = [NSString stringWithFormat:@"%@", item.defindex];
if([defindex1 isEqualToString:defindex2])
{
//NSLog(@"%@", item.item_name);
backpackIcons *backpack = [[backpackIcons alloc] init];
backpack.pos_att = @"";
backpack.neg_att = @"";
backpack.neutral_att = @"";
//name of item
if([item.proper_name boolValue])
{
backpack.name = @"The ";
backpack.name = [backpack.name stringByAppendingString:item.item_name];
}
else
{
backpack.name = item.item_name;
}
backpack.original_id = group.original_id; //id of the item
backpack.defindex = item.defindex; //defindex number of the item
backpack.level = group.level; //level of the item
backpack.quality = group.quality; //quality of the item
backpack.image_url = item.image_url; //image of the item
backpack.item_description = item.item_description; //description of the item
backpack.image_url_large = item.image_url_large; //large image of the item
backpack.item_type = item.item_type_name; //type of item
//find origin of item
if(group.origin != NULL) {
backpack.origin = [item.originNames objectAtIndex:[group.origin integerValue]];
}
else {
backpack.origin = @"";
}
if([group.flag_cannot_craft boolValue])
{
//item isn't craftable
backpack.not_craftable = @"(Not Craftable)";
}
if([group.flag_cannot_trade boolValue])
{
//item isn't tradable
backpack.not_tradable = @"(Not Tradable)";
}
//custom name
if(group.custom_name != NULL) {
backpack.custom_name = group.custom_name;
}
//custom description
if(group.custom_desc != NULL) {
backpack.custom_desc = group.custom_desc;
}
//find positive and negative attributes of the item
if(group.attributes.count != 0) {
for(NSInteger num = 0; num < group.attributes.count; num++) {
NSString *att_def = [NSString stringWithFormat:@"%@",[[group.attributes objectAtIndex:num] valueForKey:@"defindex"]];
//NSLog(att_def);
for(NSInteger num2 = 0; num2 < item.attributes.count; num2++) {
NSString *att_def2 = [NSString stringWithFormat:@"%@", [[item.attributes objectAtIndex:num2] valueForKey:@"defindex"]];
//defindex of 214 is for counting kills on strange weapons
if(att_def2 != NULL) {
if ([att_def isEqualToString:att_def2]) {
//we have found the attribute!
if(![[[item.attributes objectAtIndex:num2] valueForKey:@"hidden"] boolValue]) {
//item isn't hidden from view
if(![[[item.attributes objectAtIndex:num2] valueForKey:@"stored_as_integer"] boolValue]) {
//we use the float value
if([[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] isEqualToString:@"1"] || [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] isEqualToString:@"0"]) {
//the attribute is string only, it has no values
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
NSString *attribute = [[item.attributes objectAtIndex:num2] valueForKey:@"description_string"];
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
else {
//the attribute uses values given my the float_value key
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
double y = [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] doubleValue];
NSInteger z;
if([[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] rangeOfString:@"%s1%"].location != NSNotFound) {
//for values with percentages
z = lroundf(y*100);
if(z >= 100) {
z = z - 100;
}
}
else {
//for values that are just integers
z = y;
}
NSString *a = [NSString stringWithFormat:@"%d", z];
NSString *attribute = [[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] stringByReplacingOccurrencesOfString:@"%s1" withString:a];
//NSLog(attribute);
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
}
else {
//we use the integer value
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
NSInteger y = [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"value"]] integerValue];
NSString *a = [NSString stringWithFormat:@"%d", y];
NSString *attribute = [[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] stringByReplacingOccurrencesOfString:@"%s1" withString:a];
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
}
}
}
}
}
}
[backpackItems addObject:backpack];
}
}
}
return backpackItems;
}
设置属性值的实际代码：
if(![[[item.attributes objectAtIndex:num2] valueForKey:@"stored_as_integer"] boolValue]) {
//we use the float value
if([[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] isEqualToString:@"1"] || [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] isEqualToString:@"0"]) {
//the attribute is string only, it has no values
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
NSString *attribute = [[item.attributes objectAtIndex:num2] valueForKey:@"description_string"];
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
else {
//the attribute uses values given my the float_value key
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
double y = [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"float_value"]] doubleValue];
NSInteger z;
if([[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] rangeOfString:@"%s1%"].location != NSNotFound) {
//for values with percentages
z = lroundf(y*100);
if(z >= 100) {
z = z - 100;
}
}
else {
//for values that are just integers
z = y;
}
NSString *a = [NSString stringWithFormat:@"%d", z];
NSString *attribute = [[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] stringByReplacingOccurrencesOfString:@"%s1" withString:a];
//NSLog(attribute);
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
}
else {
//we use the integer value
NSString *att_type = [[item.attributes objectAtIndex:num2] valueForKey:@"effect_type"];
NSInteger y = [[NSString stringWithFormat:@"%@", [[group.attributes objectAtIndex:num] valueForKey:@"value"]] integerValue];
NSString *a = [NSString stringWithFormat:@"%d", y];
NSString *attribute = [[[item.attributes objectAtIndex:num2] valueForKey:@"description_string"] stringByReplacingOccurrencesOfString:@"%s1" withString:a];
if([att_type isEqualToString:@"positive"]) {
backpack.pos_att = [backpack.pos_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else if ([att_type isEqualToString:@"negative"]) {
backpack.neg_att = [backpack.neg_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
} else {
backpack.neutral_att = [backpack.neutral_att stringByAppendingString:[NSString stringWithFormat:@"%@\n", attribute]];
}
}
}
答案 0 :(得分：0)
似乎问题是我的包含每个项目属性的数组groups.attributes每个属性都有两次，所以我初始化错了。感谢所有帮助过的人。
