设置App的名称

设置App的启动图片

需要注意点是，App要杀掉重启才能显示出启动图片

2种方法防止图片被渲染

1.

vc02.tabBarItem.image = [UIImage imageNamed:@"tabBar_new_icon"];

UIImage *image = [UIImage imageNamed:@"tabBar_new_click_icon"];

image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

vc02.tabBarItem.selectedImage = image;

2.

文字被渲染解决方法

1.

vc02.tabBarItem.title = @"新帖";

NSMutableDictionary *attrs = [NSMutableDictionary dictionary];

attrs[NSForegroundColorAttributeName] = [UIColor grayColor];

[vc02.tabBarItem setTitleTextAttributes:attrs forState:UIControlStateNormal];

NSMutableDictionary *attrs1 = [NSMutableDictionary dictionary];

attrs1[NSForegroundColorAttributeName] = [UIColor blackColor];

[vc02.tabBarItem setTitleTextAttributes:attrs1 forState:UIControlStateSelected];

2.

• 通过appearance统一设置所有UITabBarItem的文字属性
• 后面带有UI_APPEARANCE_SELECTOR的方法，都可以通过appearance对象来统一设置

NSMutableDictionary *dic = [NSMutableDictionary dictionary];

dic[NSForegroundColorAttributeName] = [UIColor grayColor];

NSMutableDictionary *selectedDic = [NSMutableDictionary dictionary];

selectedDic[NSForegroundColorAttributeName] = [UIColor darkGrayColor];

UITabBarItem *item = [UITabBarItem appearance];

[item setTitleTextAttributes:dic forState:UIControlStateNormal];

[item setTitleTextAttributes:selectedDic forState:UIControlStateSelected];
