UIBarButtonItem设置Badge
简介 UIBarButtonItem 默认是不能 设置 Badge 所以我们可以对它扩展使之支持 实现方法 添加如下代码 UIBarButtonItem+Badge.h #import <UIKit/ UIKit.h> @interface UIBarButtonItem (Badge) @property (strong, nonatomic) UILabel *badge; // Badge shouldHideBadgeAtZero; // Badge has a bounce animation when value changes @property BOOL shouldAnimateBadge; @end UIBarButtonItem +Badge.m #import <objc/runtime.h> #import "UIBarButtonItem+Badge.h" NSString const *badgeKey = @"badgeKey shouldAnimateBadgeKey = @"shouldAnimateBadgeKey"; NSString const *badgeValueKey = @"badgeValueKey"; @implementation UIBarButtonItem

iOS键盘、选取器上的工具栏
我们用了一个UIBarButtonItem组成的数组，因为可以放多个按钮，只要在数组中继续添加就可以了，最后将数组作为工具栏的Items添加进去就可以了。 *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:@"取消" style:UIBarButtonItemStyleBordered target: *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 的数组，来存储三个UIBarButtonItem对象，注意，为什么是三个呢，界面上不是只有取消和完成两个按钮吗？ 其余两个按钮的代码不多说了，挺简单的，这个占位按钮很有意思： UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem
