ios使用xib自定义uiview">iOS使用xib自定义UIView

1 重写init方法

2 加载Xib中的view (就是这样)

NSArray *arr = [[NSBundle mainBundle] loadNibNamed:@”JFcustomHeadView” owner:self options:nil];

//自定义View

- (instancetype)initWithFrame:(CGRect)frame{
    self = [super initWithFrame:frame];
    if (self) {
        [self baseInit];
    }
    return self;
}

-(void)baseInit{
    NSArray *arr = [[NSBundle mainBundle] loadNibNamed:@"JFcustomHeadView" owner:self options:nil];
    UIView *view = nil;
    for (id obj in arr) {
        if ([obj isKindOfClass:[UIView class]]) {
            view = obj;
            break;
        }
    }
    if (view != nil) {
        [self addSubview:view];
    }
}
- (void)layoutSubviews{
    self.frame = CGRectMake(0,0, NEWWIDTH, 40);
    self.backgroundColor = [UIColor whiteColor];
}
