UIStepper非常方便,但我想改变它的外观,我需要有自定义图标而不是加号和减号,我也想改变控件的颜色.我怎样才能做到这一点？提前致谢!

我有问题将值传递给destinationViewController的IBOutlet属性,但它在普通属性上工作正常,请参阅下面的代码

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"NewsCellToDetail"]) {        
    testViewController *viewController = segue.destinationViewController;
    viewController.titleLabel.text = @"test"; // set the IBOutlet label text to something
    NSLog(@"%@",viewController.titleLabel.text); // this will output to nil
    viewController.textTest = @"testing2"; // set the property to something
    NSLog(@"%@", viewController.textTest) // this will output the string testing2
}

这是头文件testviewcontroller.h的代码

#import <UIKit/UIKit.h>
@interface NewsDetailViewController : UIViewController
@property (strong, nonatomic) IBOutlet UILabel *titleLabel;
@property (strong, nonatomic) NSString *textTest;
@end

我已经合成了这两个属性.

谢谢您的帮助.
