####解决图片渲染问题
UIImage* image = [UIImage imageNamed:@"tabBar_essence_click_icon"];
//设置image模式是原始效果,不要渲染
image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
vc1.tabBarItem.selectedImage = image;
####修改项目名称
####通过appearance同一设置所有UITabBarItem的文字属性
NSMutableDictionary* attrs = [NSMutableDictionary new];
//文字 字体大小
attrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];
//文字 Foreground前景颜色
attrs[NSForegroundColorAttributeName] = [UIColor grayColor];
NSMutableDictionary* selectesAttrs = [NSMutableDictionary new];
selectesAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];
selectesAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];
UITabBarItem* item = [UITabBarItem appearance];
[item setTitleTextAttributes:attrs forState:UIControlStateNormal];
[item setTitleTextAttributes:selectesAttrs forState:UIControlStateSelected];
####设置cell默认选中第一行
//设置左边列表cell默认选中首行
[self.LeftTableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:UITableViewScrollPositionTop];
####李明杰第三方转模型框架使用
//通过数组responseObject[@"list"]进行转模型LXRRecommendLeftModel到LeftDataArray数组里
self.LeftDataArray = [LXRRecommendLeftModel mj_objectArrayWithKeyValuesArray:responseObject[@"list"]];
####重写方法
#pragma mark - 重写选中方法,系统默认选中将所有子控件显示为高亮状态---------重点
//selected会打印出选中第几组第几行信息
/**可以在这个方法中监听cell的选中和取消选中*/
-(void)setSelected:(BOOL)selected animated:(BOOL)animated{
[super setSelected:selected animated:animated];
self.SelctedView.hidden = !selected;
//设置文字颜色,如果是选中状态是红色,如果不是就是正常颜色
self.textLabel.textColor = selected ? LXR_RGB_Color(219, 21, 26) : LXR_RGB_Color(78, 78,78);
//设置正常状态下文本颜色
//self.textLabel.textColor = LXR_RGB_Color(78, 78, 78);
//默认选中cell时textLable就会变成高亮颜色
//self.textLabel.highlightedTextColor = LXR_RGB_Color(219, 21, 26);
}
####pch文件设置
//调试
#ifdef DEBUG
#define LXRLog(...) NSLog(__VA_ARGS__)
#else
#define LXRLog(...)
#endif
//打印执行方法
#define LXRLogFunc LXRLog(@"%s",__func__)
//设置颜色
#define LXR_RGB_Color(r,g,b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]
####自定义NavigationController 重写方法
//可以在这个方法中拦截所有PUSH进来的控制器
-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
//统一设置控制器返回按钮的文字
if (self.childViewControllers.count > 0) { //如果push进来的不是第一个控制器
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
//设置文字 颜色
[button setTitle:@"返回" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
//设置按钮图片
[button setImage:[UIImage imageNamed:@"navigationButtonReturn"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"navigationButtonReturnClick"] forState:UIControlStateHighlighted];
//设置按钮大小,一定要设置大小,不然显示不出来
button.Size = CGSizeMake(60, 30);
//让按钮内容的所有内容左对齐
//button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
//根据大小填充 建议使用
[button sizeToFit];
//设置按钮贴着屏幕左边 ---------重点!!!
button.contentEdgeInsets = UIEdgeInsetsMake(0, -20, 0, 0);
//添加点击事件 返回界面功能
[button addTarget:self action:@selector(Back) forControlEvents:UIControlEventTouchUpInside];
viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:button];
//当push下一界面的时候,隐藏tabBar
viewController.hidesBottomBarWhenPushed = YES;
}
//这句super的push要放在后面,让viewController可以覆盖上面设置的leftBarButtonItem
[super pushViewController:viewController animated:animated];
}
####重写initialize方法 作用
#pragma mark - 设置主题 这个方法只调用一次
+(void)initialize{
//通过appearance同一设置所有UITabBarItem的文字属性
NSMutableDictionary* attrs = [NSMutableDictionary new];
//文字 字体大小
attrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];
//文字 Foreground前景颜色
attrs[NSForegroundColorAttributeName] = [UIColor grayColor];
NSMutableDictionary* selectesAttrs = [NSMutableDictionary new];
selectesAttrs[NSFontAttributeName] = attrs[NSFontAttributeName];
selectesAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];
UITabBarItem* item = [UITabBarItem appearance];
[item setTitleTextAttributes:attrs forState:UIControlStateNormal];
[item setTitleTextAttributes:selectesAttrs forState:UIControlStateSelected];
}
####重写setFrame和setBounds方法作用
/**
* 需要重写setFrame和setBounds方法作用:
* 重新布局cell,拦截设置方法后进行重新赋值,别人无法改变
*/
-(void)setFrame:(CGRect)frame{
//cell效果,x往右移动10,宽度减少2倍的x,高度减少1
frame.origin.x = 10;
frame.size.width -= 2*frame.origin.x;
frame.size.height -= 1;
[super setFrame:frame];
}
-(void)setBounds:(CGRect)bounds{
//cell效果,x往右移动10,宽度减少2倍的x,高度减少1
bounds.origin.x = 10;
bounds.size.width -= 2*bounds.origin.x;
bounds.size.height -= 1;
[super setBounds:bounds];
}
####修改UITextField的placeholder颜色
@property(nonatomic,copy) NSAttributedString *attributedPlaceholder;
// 文字属性
NSMutableDictionary *attrs = [NSMutableDictionary dictionary];
attrs[NSForegroundColorAttributeName] = [UIColor grayColor];
// NSAttributedString : 带有属性的文字(富文本技术)
NSAttributedString *placeholder = [[NSAttributedString alloc] initWithString:@"手机号" attributes:attrs];
self.phoneField.attributedPlaceholder = placeholder;
NSMutableAttributedString *placehoder = [[NSMutableAttributedString alloc] initWithString:@"手机号"];
[placehoder setAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]} range:NSMakeRange(0, 1)];
[placehoder setAttributes:@{
NSForegroundColorAttributeName : [UIColor yellowColor],
NSFontAttributeName : [UIFont systemFontOfSize:30]
} range:NSMakeRange(1, 1)];
[placehoder setAttributes:@{NSForegroundColorAttributeName : [UIColor redColor]} range:NSMakeRange(2, 1)];
self.phoneField.attributedPlaceholder = placehoder;
- (void)drawPlaceholderInRect:(CGRect)rect
{
[self.placeholder drawInRect:CGRectMake(0, 10, rect.size.width, 25) withAttributes:@{
NSForegroundColorAttributeName : [UIColor grayColor],
NSFontAttributeName : self.font}];
}
[self setValue:[UIColor grayColor] forKeyPath:@"_placeholderLabel.textColor"];
unsigned int count = 0;
// 拷贝出所有的成员变量列表
Ivar *ivars = class_copyIvarList([UITextField class], &count);
for (int i = 0; i<count; i++) {
// 取出成员变量
// Ivar ivar = *(ivars + i);
Ivar ivar = ivars[i];
// 打印成员变量名字
XMGLog(@"%s", ivar_getName(ivar));
}
// 释放
free(ivars);

####比较某时间与目前时间
第一种方法,推荐-(void)testDate:(NSString*)create_time{
//日期格式化类
NSDateFormatter* fmt = [[NSDateFormatter alloc]init];
//设置日期格式(y:年,M:月,d:天 H:24消失,小写h:12小时,m:分钟,s:秒)
fmt.dateFormat = @"yyyy-MM-dd HH-mm-ss";
//当前时间
NSDate* now = [NSDate date];
//发帖时间
NSDate* create = [fmt dateFromString:create_time];
//日历
NSCalendar* calendar = [NSCalendar currentCalendar];
//比较时间
NSCalendarUnit unit = NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond;
NSDateComponents* cmps = [calendar components:unit fromDate:create toDate:now options:0];
LXRLog(@"%@ %@",create,now);
LXRLog(@"%zd %zd %zd %zd %zd %zd",cmps.year,cmps.month,cmps.day,cmps.hour,cmps.minute,cmps.second);
//获得NSDate的每一个元素
NSInteger year = [calendar component:NSCalendarUnitYear fromDate:now];
NSInteger month = [calendar component:NSCalendarUnitMonth fromDate:now];
NSInteger day = [calendar component:NSCalendarUnitDay fromDate:now];
NSDateComponents* cmps = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:now];
}
第二种方法,比较恶心/**比较时间方法*/
-(void)testDate:(NSString*)create_time{
//当前时间
NSDate* now = [NSDate date];
//发帖时间
NSDateFormatter* fmt = [[NSDateFormatter alloc]init];
//设置日期格式(y:年,M:月,d:天 H:24消失,小写h:12小时,m:分钟,s:秒)
fmt.dateFormat = @"yyyy-MM-dd HH-mm-ss";
NSDate* create = [fmt dateFromString:create_time];
//比较时间 NSTimeInterval-->double类型
NSTimeInterval delta = [now timeIntervalSinceDate:create];
}
####字典转模型 第三方框架使用
/**把系统返回的id重新命名新的ID*/
/**第一种方法*/
+(NSDictionary *)mj_replacedKeyFromPropertyName{
return @{@"ID" : @"id"};
}
/**第二种方法*/
+(NSString *)mj_replacedKeyFromPropertyName121:(NSString *)propertyName{
if ([propertyName isEqualToString:@"id"]) return @"ID";
return propertyName;
}
####当设置好Frame,打印结果与设置无问题的时候,达不到预期的效果
//首先考虑是系统的自动调整属性-->设置不用自动调整
self.autoresizingMask = UIViewAutoresizingNone;
####图片保存到相册
系统自带方法
代码写入
/**保存图片*/
- (IBAction)Save {
//将图片写入相册
UIImageWriteToSavedPhotosAlbum(self.imageView.image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
}
/**系统建议命名此方法*/
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
if (error) {
[MBProgressHUD showError:@"保存失败!"];
}else{
[MBProgressHUD showSuccess:@"保存成功!"];
}
}
####第三方FaceBook动画框架使用
#if 0
pop和CoreAnimation的区别:
1.CoreAnimation的动画只能添加到Layer上
2.pop的动画能添加到任何对象上
3.pop的底层并非基于CoreAnimation,是基于CADisplayLink
4.CoreAnimation的动画仅仅是表象,并不会真正修改对象的Frame/Size等值
5.pop的动画实时修改对象的属性,真正地修改了对象的属性
#endif
/**pop简介*/
-(void)POPintro{
//kPOPViewCenter是根据 View 中心点进行动画
POPSpringAnimation* ani = [POPSpringAnimation animationWithPropertyNamed:kPOPViewCenter];
//动画开始时间(拿到当前时间+自定义时间)
ani.beginTime = CACurrentMediaTime() + 1.0;
//弹簧效果设置
ani.springBounciness = 20;//弹力效果模式是4,范围是[0.20]
ani.springSpeed = 20; //速度模式是12,范围是[0,20]
//包装View开始值--->CGPoint
ani.fromValue = [NSValue valueWithCGPoint:CGPointMake(self.sloganView.centerX, self.sloganView.centerY)];
//包装View最终值--->CGPoint
ani.toValue = [NSValue valueWithCGPoint:CGPointMake(self.sloganView.centerX, 400)];
//添加动画 key可是储存值,方便查找和释放
[self.sloganView pop_addAnimation:ani forKey:nil];
//kPOPLayerPositionY是根据 Layer 中心点进行动画
POPSpringAnimation* ani = [POPSpringAnimation animationWithPropertyNamed:kPOPLayerPositionY];
//动画开始时间(拿到当前时间+自定义时间)
ani.beginTime = CACurrentMediaTime() + 1.0;
//弹簧效果设置
ani.springBounciness = 20;//弹力效果模式是4,范围是[0.20]
ani.springSpeed = 20; //速度模式是12,范围是[0,20]
//包装Layer改变范围
ani.fromValue = @(self.sloganView.layer.position.y);
ani.toValue = @(400);
//添加动画 key可是储存值,方便查找和释放
[self.sloganView pop_addAnimation:ani forKey:nil];
}
####IOS8版本 系统自动计算Cell高度方法
/***重点:cell的高度高度 (IOS8版本以后可以自动设置Cell的高度)****/
//估计高度
self.tableView.estimatedRowHeight = 44;
//系统自带自动根据估计高度计算Cell合适的高度
self.tableView.rowHeight = UITableViewAutomaticDimension;
####设置状态栏方法
1.info文件修改设置
2.代码设置状态
####得到按钮有图片时的Size,和图片大小一样
/**得到按钮有图片时的Size,和图片大小一样*/
addButton.size = [UIImage imageNamed:@"tag_add_icon"].size;
addButton.size = [addButton imageForState:UIControlStateNormal].size;
addButton.size = addButton.currentImage.size;
重点!!!找出上一界面的导航控制器(Push和Modal两种方法)Push
// 如果控制器'a'->通过Push->另一个控制器'b',控制器'b'要拿到'a'导航栏控制器
// 1.取出当前的TabBarController->通过系统keyWindow的跟控制器拿到
UITabBarController *tabBarVc = (UITabBarController *)[UIApplication sharedApplication].keyWindow.rootViewController;
// 2.在通过拿到的tabBarVc->通过当前选中的selectedViewController拿到当前所在的导航控制器
UINavigationController *navVc = (UINavigationController *)tabBarVc.selectedViewController;
// 3.通过Push到下一界面
[navVc pushViewController:想要跳转到的控制器 animated:YES];
modal
// 如果控制器'a'->通过modal->另一个控制器'b',控制器'b'要拿到'a'导航栏控制器
// 根据展示控制器的属性
//a.presentedViewController -> b控制器
//b.presentingViewController -> a控制器
UIViewController* root = [UIApplication sharedApplication].keyWindow.rootViewController;
UINavigationController* navVc = (UINavigationController*)root.presentedViewController;
[navVc pushViewController:想要跳转到的控制器 animated:YES];
