green:((float)((hexValue & 0xFF00) >> 8)) / 255.0
blue:((float)(hexValue & 0xFF)) / 255.0 alpha:alphaValue];
}
UIView
· 对View设置圆角（在layoutSubviews里面进行调用 (适合少数量View的圆角设置
.h
- (void)makeCornerWithRadius:(float)radius;
.m
- (void)makeCornerWithRadius:(float)radius {
self.layer.cornerRadius = self.frame.size.width * radius;
self.layer.masksToBounds = YES;
}
· 添加/移去一个警示标语（当用户在TextField里面输入了错误信息的时候提示使用
.h
- (void)showRegularExpressionAlertMessage:(NSString *)message;
- (void)removeRegularExpressionAlertMessage;
.m
#define kSubViewTag 1024
- (void)showRegularExpressionAlertMessage:(NSString *)message {
if ([self viewWithTag:kSubViewTag]) return;
UILabel *label = [[UILabel alloc] init];
[self addSubview:label];
label.text = message;
label.backgroundColor = [[UIColor redColor] colorWithAlphaComponent:0.2];
label.textColor = [UIColor redColor];
label.alpha = 0;
label.tag = kSubViewTag;
label.font = [UIFont systemFontOfSize:13];
label.textAlignment = NSTextAlignmentRight;
label.frame = CGRectMake(self.frame.size.width, 0, self.frame.size.width, self.frame.size.height);
[UIView animateWithDuration:0.3 animations:^{
CGRect frame = label.frame;
frame.origin.x = 0;
label.frame = frame;
label.alpha = 1;
}];
}
- (void)removeRegularExpressionAlertMessage {
UIView *view = [self viewWithTag:kSubViewTag];
if (view) {
[UIView animateWithDuration:0.5 animations:^{
CGRect frame = view.frame;
frame.origin.x = self.frame.size.width;
view.frame = frame;
view.alpha = 0;
} completion:^(BOOL finished) {
[view removeFromSuperview];
}];
}
}
这里是直接盖一层控件上去，也可以直接修改原View的layer，比如一个小红框（需要提示的View拿到了，自然由我们折腾。
· 给View的四周添加阴影，阴影的效果（这里是画出四个二元曲线
.h
- (void)makeShadow;
.m
- (void)makeShadow {
self.layer.shadowColor = [UIColor colorWithHex:0x6e6e6e].CGColor;//shadowColor阴影颜色
self.layer.shadowOffset = CGSizeMake(0,0);//shadowOffset阴影偏移，默认(0, -3),这个跟shadowRadius配合使用
self.layer.shadowOpacity = 1;//阴影透明度，默认0
self.layer.shadowRadius = 2;//阴影半径，默认3
//路径阴影
UIBezierPath *path = [UIBezierPath bezierPath];
float width = self.bounds.size.width;
float height = self.bounds.size.height;
float x = self.bounds.origin.x;
float y = self.bounds.origin.y;
float addWH = 10;
CGPoint topLeft = self.bounds.origin;
CGPoint topRight = CGPointMake(x+width,y);
CGPoint bottomRight = CGPointMake(x+width,y+height);
CGPoint bottomLeft = CGPointMake(x,y+height);
CGPoint topMiddle = CGPointMake(x+(width/2),y-addWH);
CGPoint leftMiddle = CGPointMake(x-addWH,y+(height/2));
CGPoint rightMiddle = CGPointMake(x+width+addWH,y+(height/2));
CGPoint bottomMiddle = CGPointMake(x+(width/2),y+height+addWH);
[path moveToPoint:topLeft];
//添加四个二元曲线
[path addQuadCurveToPoint:topRight
controlPoint:topMiddle];
[path addQuadCurveToPoint:bottomRight
controlPoint:rightMiddle];
[path addQuadCurveToPoint:bottomLeft
controlPoint:bottomMiddle];
[path addQuadCurveToPoint:topLeft
controlPoint:leftMiddle];
//设置阴影路径
self.layer.shadowPath = path.CGPath;
}
UIButton
· 一句代码实现初始化一个发送验证码倒计时的Button（在ViewDidLoad里面就可以初始化（在开始的Block里面调用接口UIButton
2016.5.27 update
对计时机制做了优化。
原始的方式是通过内存中存储的count数进行递减。
当app处于后台的时候，程序并没有持续进行，实际的时间差和显示的有出入。
更新使用了本地时间戳来判断，较原先方法更为准确。
同时对移除控件时候做了判断，清除缓存数据。
.h
typedef void(^StartBlock)(void);
typedef void(^CompleteBlock)(void);
- (void)addTimerForVerifyWithInterval:(NSUInteger)interval start:(StartBlock)startBlock complete:(CompleteBlock)completeBlock;
.m
#define kVerifyMsgTake @"获取验证码"
#define kVerifyMsgDidToke @"验证码已发送"
#define kVerifyMsgLoad @"秒后重新获取"
static const char *verifyStartBlockKey = "verifyStartBlockKey"; // 开始回调
static const char *verifyCompleteBlockKey = "verifyCompleteBlockKey"; // 完成回调
static const char *verifyTimerKey = "verifyTimerKey"; // 计时器
static const char *verifyStatusKey = "verifyStatusKey"; // 状态（移除时候判断用
static const char *verifyIntervalKey = "verifyIntervalKey"; // 总时间
static const char *verifyStartIntervalKey = "verifyStartIntervalKey"; // 开始时间戳

}
- (void)removeFromSuperview {
if ([objc_getAssociatedObject(self, verifyStatusKey) boolValue]) {
objc_removeAssociatedObjects(self);
}
[super removeFromSuperview];
}
UIScrollView
· 设置ScrollView的偏移（用户输入信息的时候浮动TextField
- (void)moveWithOffset:(CGFloat)offset;
- (void)moveWithOffset:(CGFloat)offset {
if (self.contentInset.top != offset) {
[UIView animateWithDuration:0.3 animations:^{
self.contentInset = UIEdgeInsetsMake(offset, 0, 0, 0);
}];
}
}
UIBarButtonItem
· 导航栏被自定义，或者某个页面需要对导航栏的返回按键单独处理的时候可以使用（单纯为了节约代码）
建议根据需求把图片名字或者Title提出来作为参数。
.h
+ (instancetype)backBarButtonWithTarget:(id)target action:(SEL)action;
.m
+ (instancetype)backBarButtonWithTarget:(id)target action:(SEL)action {
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
[button setImage:[UIImage imageNamed:@"一张返回图片"] forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, 30, 30);
// 控制图片的缩进大小
[button setImageEdgeInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
return [[self alloc] initWithCustomView:button];
}
