init 方法内部会调用initWithFrame:方法
ShopView *shopView = [[ShopView alloc] init];
打印结果
viewControll生命周期[946:54524] -[ShopView initWithFrame:]
viewControll生命周期[946:54524] -[ShopView init]
initWithFrame:方法内部不会调用init 方法
ShopView *shopView = [[ShopView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
打印结果
