objective-c - NSCombobox 的动态数据

Question

如何在xcode中使用objective c和cocoa框架动态添加NSComboBox数据？

-(void)awakeFromNib
{
    NSLog(@"View controller instance with view: %@", self.view);


    char* data = getData(); // I will be using data to populate records below


    // Setup combo box with data from getData() instead of dummy apple, bag, cat, dog
    self.myRecords = @[@“apple”, @“bag”, @“cat”, @“dog"];
    [self.myRecordsCombo addItemsWithObjectValues:self.myRecords];


 }

 // C Method
 int
 getData()
 {
     char name[128];
     NSString *str;

    while(/*traverse through data for combo box */){
        NSString *tempName = [NSString stringWithFormat:@"%c", name];         
        str = [str stringByAppendingString:tempName];

        ....
    }
    NSLog(str); //will be passed to awakeFromNib and populate to combo box


 }

似乎无法获得正确的字符串，因为它最终会产生垃圾变量。

首先您需要创建项目列表。 (NSArray)。

NSArray *items = @[@"Apple", @"Ball", @"Cat", @"Doll"];

删除所有现有项目，因为默认情况下会将三个项目添加到组合框中。

[self.comboBox removeAllItems];

现在将您的项目添加到组合框中:

[self.comboBox addItemsWithObjectValues:items];
