一、Value stored to '' during its initialization is never read这个值并无被使用,注释或者删除便可;还有一种状况就是,初始化了两次
bash
二、Passed-by-value struct argument contains uninitialized data (e.g., field: '')项目中的值没有及时的初始化,初始化使用后便可ui
三、The 'viewWillAppear:' instance method in UIViewController subclass '' is missing a [super viewWillAppear:] call
spa
没有调用super方法code
四、Returning 'self' while it is not set to the result of '[(super or self) init...]'
cdn
修改为以下blog
- (instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self layoutUI];
}
return self;
}
