使用 xib 添加 UIView 子类到 UIViewController
我在这里做错了什么？
创建：
CustomTab.h
#import <UIKit/UIKit.h>
@interface CustomTab : UIView {
IBOutlet UIView *view;
}
@property (nonatomic, retain) IBOutlet UIView *view;
@end
CustomTab.m
#import "CustomTab.h"
@implementation CustomTab
@synthesize view;
- (id)initWithFrame:(CGRect)frame {
if ((self = [super initWithFrame:frame])) {
// Initialization code
}
return self;
}
- (void)dealloc {
[super dealloc];
}
@end
- XIB 文件将其文件所有者设置为 CustomTab 的类，连接视图
在我的 UIViewController 类
- (void)viewDidLoad {
[super viewDidLoad];
CGRect frame = CGRectMake(0, 0, 320, 40); // Replacing with your dimensions
CustomTab *myObj = [[CustomTab alloc] initWithFrame:frame];
[self.view addSubview:myObj.view];
[myObj release];
}
中子视图不会出现在屏幕上。我缺少什么？
What am I doing wrong here?
Created:
CustomTab.h
#import <UIKit/UIKit.h>
@interface CustomTab : UIView {
IBOutlet UIView *view;
}
@property (nonatomic, retain) IBOutlet UIView *view;
@end
CustomTab.m
#import "CustomTab.h"
@implementation CustomTab
@synthesize view;
- (id)initWithFrame:(CGRect)frame {
if ((self = [super initWithFrame:frame])) {
// Initialization code
}
return self;
}
- (void)dealloc {
[super dealloc];
}
@end
- XIB file set its files owner to be CustomTab's class, hooked up the view
In my UIViewController class
- (void)viewDidLoad {
[super viewDidLoad];
CGRect frame = CGRectMake(0, 0, 320, 40); // Replacing with your dimensions
CustomTab *myObj = [[CustomTab alloc] initWithFrame:frame];
[self.view addSubview:myObj.view];
[myObj release];
}
The subview doesnt appear on the screen. What am I missing?

nib 文件不会自动将其自身绑定到您的 UIView。如果您的视图是所有者，我想您可以在初始化视图后使用
NSBundle接口的loadNibNamed:owner:来加载您的视图。The nib file does not bind itself to your UIView automatically. If your view is owner, I guess you can use
loadNibNamed:owner:ofNSBundleinterface to load your view after your have init your view.
