我有一個函數來初始化一個揹包對象的數組，而揹包對象的屬性是正數，負數和中性屬性，它們都是NSString。的問題是，當我初始化屬性的值，相同的值重複兩次（登錄時的它的值）NSString具有相同的值兩次
的代碼：

的實際代碼來設置的值屬性：
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]];
}
}
}
代碼太多！我沒有時間或傾向去閱讀它。請構建一個演示此問題的較小示例。 – trojanfoe
@trojanfoe好吧 –
你聲稱*相同的值重複兩次（當我記錄它的值）*，但代碼中沒有未註釋的'NSLog（）'語句。我想你可以從斷點記錄數值，但是如果你提供的代碼重現了問題，那將會很好。 @trajanfoe是對的 - 你應該把代碼縮小到一個更小的例子。大部分代碼與字符串無關。 – Caleb
