之前都是用我自己手機(jī)調(diào)試（iOS11）都沒什么問題，今天用同事（iOS10.3.1）手機(jī)build竟然crash了，看了下crash的地方，進(jìn)入加載xib的地方。所有這樣加載的代碼都會(huì)crash，奇怪！，xib中沒有設(shè)置file'sOwner,關(guān)聯(lián)了xib對(duì)應(yīng)的class。

[[NSBundle mainBundle] loadNibNamed: nibName  owner: nil options:nil]

完整代碼

@implementation ContactInfoDetailView

- (void)awakeFromNib {
    [super awakeFromNib];
    [_iconLabel addCornerWithRadius: 6.f directions: UIRectCornerAllCorners];
}

+ (ContactInfoDetailView *)getContactInfoView {
    NSString *nibName = NSStringFromClass([self class]);
    ContactInfoDetailView *view = [[[NSBundle mainBundle] loadNibNamed: nibName  owner: nil options:nil] firstObject];
    
    return view;
}
