修改系统的UITableView的分割线

[self.subviews enumerateObjectsUsingBlock:^(__kindof UIView * _Nonnull subView, NSUInteger idx, BOOL * _Nonnull stop) {
   if ([subView isKindOfClass:NSClassFromString(@"_UITableViewCellSeparatorView")]) {
        subView.x = 0;
       subView.width = ScreenWidth;
       subView.backgroundColor = [XCFColor colorTableSeparatorColor];
   }
}];

查看我添加RAC的代码位置请使用 FIXME

添加大神讲的教程RAC，详细教程找码神吴彦祖最常用的几招：（死记硬背都能会的） target-action：文本框事件： UITextField * textField = [[UITextField alloc]init]; @weakify(self); // _weak typeof(self) self_weak = self;

[textField mas_makeConstraints:^(MASConstraintMaker *make) {
    
    @strongify(self);   //  __strong __typeof__(self) self = self_weak_;
    make.size.mas_equalTo(CGSizeMake(180, 40));
    make.center.equalTo(self.view);
}];

[[textField rac_signalForControlEvents:UIControlEventEditingChanged]
subscribeNext:^(id x) { LxDBAnyVar(x); }];

[textField.rac_textSignal subscribeNext:^(id x) { LxDBAnyVar(x);}];

Tip: id x -> NSString * text

手势：(不待演示老式的写法了)

self.view.userInteractionEnabled = YES;

UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]init];
[[tap rac_gestureSignal] subscribeNext:^(UITapGestureRecognizer * tap) {
   
    LxDBAnyVar(tap);
}];
[self.view addGestureRecognizer:tap];
