我写的是一份将在SOS3.0和上运行的文件。
该表有一套惯例<条码>。 我在我的习惯<守则>上正确宣布并综合了该编码。
我愿以动态方式制定<条码>查询/编码>的案文,并在我<条码>之前向用户展示。 UIViewController。 为论证起见,请假设案文设定方法昂贵。
渔获量为:OS3, 至少是-(id)initWith NibName:NSString *) a NibNameOrNil bundle(NSBundle *) a NibBundleOrNil 回到-(ave)viewDidLoad ,但在我的Sing4.0装置上,该表是另一个环绕。 因此,文本标签可以是nil。 我不想这样做。
因此,我不知道我能以什么方式确定案文,以便保持SOS3.0和OS4.0。
Any advice here?
请解释您的标签是怎样的。
If you have taken an outlet for the label, then in either case, in the - (void)viewDidLoad method it cannot be nil, provided the label outlet is properly connected in the xib file.
如果您没有拿到标签并按代码填写,那么在<编码>-(避免)viewDid Load方法中再次贴上标签,并在该方法上设定其案文,然后添加到观点控制者的观点中。
