view关联xib框架

h文件：

@protocol CommonViewDelegate <NSObject>
@optional
//
@end
@interface CommonView : UIView

+ (CommonView *)createViewWithDelegate:(id<CommonViewDelegate>)delegate;

@end

m文件

//
@property (assign, nonatomic) id<CommonViewDelegate>delegate;


+ (CommonView*)createViewWithDelegate:(id<CommonViewDelegate>)delegate

{
    NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CommonView" owner:self options:nil];
    if (topLevelObjects == nil || [topLevelObjects count] <= 0){
        return nil;
    }
    CommonView *view = (CommonView *)[topLevelObjects objectAtIndex:0];
    view.delegate = delegate;
    
    NSLog(@"-------1");
    return view;
}

NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CommonView" owner:self options:nil];这句会立马触发以下的方法：

-(void)awakeFromNib
{
    [super awakeFromNib];
    
    NSLog(@"---------2");
}

所以打印出来，先2后1

另外别忘了delegate是指向这个view，不是File`s Owner

还有就是，如果view 是用代码计算布局的，

记得把Autoresizing去掉，否则会冲突
