我如何能够在可可地区采取一些行动? 例如,我希望案文中的随机数字变化 每1个区都有1个区。

最佳回答

例:

 -(void)awakeFromNib {

    [NSTimer scheduledTimerWithTimeInterval:1
                                 target:self
                               selector:@selector(changeTextFieldsInt:)
                               userInfo:nil
                                repeats:YES];
}

- (void)changeTextFieldsInt:(NSTimer *)time {
     [textField setIntValue:rand()];
}
