本个章节进行BaseViewController的讲解，并放出部分源码哦
首先我们在开发一个项目搭建基类框架的时候，BaseViewController是一个非常重要的环节，后面涉及到继承，重写等各种问题，我们该考虑设计的共有api又有哪些呢，下面开始啦
导航条文本的处理
- 对应的接口
-(void)naviTitle:(NSString *)title color:(UIColor *)color font:(UIFont *)font;
-(JQBaseViewController *(^)(NSString *title))setNavTitle;
-(JQBaseViewController *(^)(UIColor *))setTitleColor;
-(JQBaseViewController *(^)(UIFont *))setTitleFont;
- 对应的函数实现
-(void)naviTitle:(NSString *)title color:(UIColor *)color font:(UIFont *)font {
self.navigationItem.title = title;
[self.navigationController.navigationBar setTitleTextAttributes:@{ NSForegroundColorAttributeName:color, NSFontAttributeName:font}];
}
-(JQBaseViewController *(^)(NSString *title))setupNaviTitle {
return ^(NSString *title) {
self.navigationItem.title = title;
return self;
};
}
-(JQBaseViewController *(^)(UIColor *))setupTitleColor {
return ^(UIColor *color) {
self.titleColor = color;
[self.navigationController.navigationBar setTitleTextAttributes:@{ NSForegroundColorAttributeName:self.titleColor, NSFontAttributeName:self.titleFont}];
return self;
};
}
-(JQBaseViewController *(^)(UIFont *))setupTitleFont {
return ^(UIFont *font) {
self.titleFont = font;
[self.navigationController.navigationBar setTitleTextAttributes:@{ NSForegroundColorAttributeName:self.titleColor, NSFontAttributeName:self.titleFont}];
return self;
};
}
- 左右按钮的响应处理问题
- 对应的接口
-(void)leftItemTitle:(NSString *)title color:(UIColor *)color font:(UIFont *)font action:(void(^)())action;
-(JQBaseViewController *(^)(NSString *title, UIColor *color, UIFont *font, void(^action)()))setLeftTitleItem;
-(void)leftImageItem:(NSString *)imageName action:(void(^)())action;
-(JQBaseViewController *(^)(NSString *imageName, void(^action)()))setLeftImageItem;
-(void)leftItems:(NSArray *)items actions:(void(^)(NSInteger index))actions;
-(JQBaseViewController *(^)(NSArray *items,void (^actions)(NSInteger index)))setLeftItems;
-(void)rightItemTitle:(NSString *)title color:(UIColor *)color font:(UIFont *)font action:(void(^)())action;
-(JQBaseViewController *(^)(NSString *title, UIColor *color, UIFont *font, void(^action)()))setRightTitleItem;
-(void)rightImageItem:(NSString *)imageName action:(void(^)())action;
-(JQBaseViewController *(^)(NSString *imageName, void(^action)()))setRightImageItem;
-(void)rightItems:(NSArray *)items actions:(void(^)(NSInteger index))actions;
-(JQBaseViewController *(^)(NSArray *items,void (^actions)(NSInteger index)))setRightItems;
- 对应的函数实现
//左按钮

self.navigationItem.rightBarButtonItems = barButtonItems;
return self;
};
}
- 间距处理问题
请在viewDidLoad函数添加一下代码
self.edgesForExtendedLayout = UIRectEdgeNone;
- 内存警告的处理
-(void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
NSLog(@"⚠️%@出现内存警告⚠️", NSStringFromClass([self class]));
}
- 对象释放情况的查看
-(void)dealloc
{
NSLog(@"%@对象释放", NSStringFromClass([self class]));
}
- 自定义加载框
注：这里是个别项目的自定义加载中样式，如何自定义，可在基类里面自行添加
-(JQToastWindow *)loadingToastView
{
if (!_loadingToastView) {
_loadingToastView = XIB(JQToastWindow);
_loadingToastView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.2];
}
return _loadingToastView;
}
- 第三方加载框
-(void)mbshowHudOnApplicationKeyWindow
{
[[MBProgressHUD showHUDAddedTo:[UIApplication sharedApplication].keyWindow animated:YES]setLabelText:@"正在加载..."];
}
-(void)mbhideHud
{
[MBProgressHUD hideHUDForView:[UIApplication sharedApplication].keyWindow animated:YES];
}
-(void)svpshowHudOnApplicationKeyWindow
{
[SVProgressHUD showWithStatus:@"正在加载..."];
}
-(void)svphideHud
{
[SVProgressHUD dismiss];
}
注：不做过多解释，相信大家都懂
- 是否显示网络状态图标
//外部需要设置**bool变量来控制是否显示*
@property (assign, nonatomic) BOOL isOpen;
-(void)setIsOpen:(BOOL)isOpen
{
_isOpen = _isOpen;
[UIApplication sharedApplication].networkActivityIndicatorVisible = isOpen；
}
- 检测登录（这里不做过多的说明了，一般都是判断session）
- 各种权限的开启--举个例子吧，定位权限，手机相机，相册什么的，这里不一一不说明了
- 分享面板的调用，由于项目不同需求，这里分享暂时不提供实例
BaseViewontroller涵盖了项目里面各个VC，以上函数足以满足大部分常用需求设置，如何自定义，即可自定在基类进行自定义添加...
