我正在寻找有关如何从XIB文件加载UIView的建议。我尝试了这个tutorial的第5个解决方案。
但是,按钮操作无效。我几乎完全按照教程设置我的项目,但IBAction根本就不会被调用。我不确定自适应布局是否会导致这种奇怪现象。
您是否愿意快速了解我项目中发生的事情?我创建了一个小项目,只是为了让按钮正常工作,并且placed here.
以下是代码段:
@interface ProfileHeadingViewOwner : NSObject
@property (nonatomic, weak) IBOutlet ProfileHeadingView *profileHeadingView;
@end
@implementation ProfileHeadingViewOwner
@end
static ProfileHeadingViewOwner* __owner = nil;
@interface ProfileHeadingView ()
@property (nonatomic, weak) IBOutlet UILabel *profileName;
@property (nonatomic, weak) UIViewController <ProfileHeadingViewDelegate> *delegateViewController;
@end
@implementation ProfileHeadingView
+(void)presentInViewController:(UIViewController<ProfileHeadingViewDelegate>*) viewController
{
// Instantiating encapsulated here.
//ProfileHeadingViewOwner *owner = [ProfileHeadingViewOwner new];
__owner = [ProfileHeadingViewOwner new];
[[NSBundle mainBundle] loadNibNamed:NSStringFromClass(self) owner:__owner options:nil];
// Pass in a reference of the viewController.
__owner.profileHeadingView.delegateViewController = viewController;
// Add (thus retain).
[viewController.view addSubview:__owner.profileHeadingView];
}
+(void)setProfileName:(NSString*)name {
__owner.profileHeadingView.profileName.text = name;
}
-(IBAction)editAvatarButtonPressed:(UIButton *)sender {
////// THIS METHOD WON'T GET CALLED. WHY? ///////
[self.delegateViewController uploadProfileAvatar:self];
}
单击按钮时,editAvatarButtonPressed
:方法不会被调用。

您的代码中存在很多问题。
__owner.profileHeadingView
UIView
。你需要删除它。要解决第一个问题,您需要这样做:
__owner = [ProfileHeadingViewOwner new];
__owner.profileHeadingView = (ProfileHeadingView *)[[[NSBundle mainBundle] loadNibNamed:NSStringFromClass(self) owner:__owner options:nil] objectAtIndex:0];
__owner.profileHeadingView.delegateViewController = viewController;
要解决第二个问题,请从以下位置更改xib设计:
