一个第三方登录底部弹出框,弹出带动画,效果图如下:

首先我们先自定义下图的这样一个控件:

KKView.h
<pre>

import <UIKit/UIKit.h>

typedef void(^KKBlock)(NSInteger index);

@interface KKView : UIView

@property (nonatomic, strong) UIButton *iconBtn;
@property (nonatomic, strong) UILabel *iconLabel;

@property (nonatomic, copy) KKBlock block;

  • (void)selectedIndex:(KKBlock)block;

@end
</pre>
然后在.m中创建视图
<pre>- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.iconBtn = [UIButton buttonWithType:(UIButtonTypeCustom)];
_iconBtn.frame = CGRectMake(self.frame.size.width/2-25, 0, 50, 50);
_iconBtn.clipsToBounds = YES;
_iconBtn.layer.cornerRadius = 25;

    [_iconBtn addTarget:self action:@selector(btnClick:) forControlEvents:(UIControlEventTouchUpInside)];
    _iconBtn.backgroundColor = [UIColor redColor];
    
    self.iconLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 60, self.frame.size.width, 20)];
    [_iconLabel setTextAlignment:(NSTextAlignmentCenter)];
    _iconLabel.font = [UIFont systemFontOfSize:14];
    _iconLabel.text = @"测试";
    _iconLabel.textColor = [UIColor blackColor];
    [self addSubview:self.iconBtn];
    [self addSubview:self.iconLabel];
    
}
return self;

}</pre>

自定义一个动画效果的展示图层
KKAnimation.h
<pre>#import <UIKit/UIKit.h>

typedef void(^KKIndexBlock)(NSInteger index);

typedef void(^KKBtnBlock)(UIButton *btn);

@interface KKAnimationView : UIView

@property (nonatomic, copy) KKIndexBlock indexBlock;

@property (nonatomic, copy) KKBtnBlock btnBlock;

/**

  • 初始化动画视图
  • @param titleArray title数组
  • @param picArray 图标数组

*/

  • (id)initWithTitleArray:(NSArray *)titleArray picArray:(NSArray *)picArray;

/**

  • 视图展示
    */
  • (void)show;

/**

  • 选中的index
    */
  • (void)selectedWithIndex:(KKIndexBlock)block;

/**

  • 按钮block
    */
  • (void)KKBtnBlock:(KKBtnBlock)block;

</pre>
循环创建 底部按钮 KKAnimation.m
<pre>for (int i = 0; i < 4; i++) {

        KKView *kk = [[KKView alloc] initWithFrame:CGRectMake(i%4*(kScreenW/4), 20, kScreenW/4, 90)];
       
        kk.tag = 100+i;
        kk.iconBtn.tag = i+1;
        [kk.iconBtn setImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@", picArray[i]]] forState:(UIControlStateNormal)];
        [kk.iconLabel setText:[NSString stringWithFormat:@"%@", titleArray[i]]];
        [kk selectedIndex:^(NSInteger index) {
           
            [self dismiss];
            self.indexBlock(index);
            
        }];
        
        [self.largeView addSubview:kk];
        
    }

</pre>
最后实现动画方法 (show)
<pre>- (void)show
{
UIWindow *window = [[UIApplication sharedApplication].windows firstObject];
[window addSubview:self];

[UIView animateWithDuration:0.2 animations:^{
    [UIView setAnimationCurve:(UIViewAnimationCurveEaseOut)];
    _largeView.transform = CGAffineTransformMakeTranslation(0, -HH);
} completion:^(BOOL finished) {
   
    for (int i = 0; i < 4; i ++) {
        
        CGPoint location = CGPointMake(kScreenW / 4 * (i%4) + (kScreenW / 8), 45);
        
        KKView *kk = (KKView *)[self viewWithTag:100 + i];
        
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.03 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            
            [UIView animateWithDuration:1.0 delay:0 usingSpringWithDamping:0.5 initialSpringVelocity:0.8 options:(UIViewAnimationOptionCurveEaseOut) animations:^{
                
                kk.center = location;
                
            } completion:nil];
            
        });
        
    }
    
}];

}
</pre>
