UI--UIImageView

前言：UI控件整理之UIImageView

一、UIImageView 效果图基本代码实现

效果图

UIImageView *imgView = [[UIImageView alloc]init];

imgView.frame = CGRectMake(20, 60, [UIScreen mainScreen].bounds.size.width - 40, 220);

imgView.contentMode = UIViewContentModeScaleAspectFit;

imgView.image = [UIImage imageNamed:@"timg"];

[self.view addSubview:imgView];

imgView.userInteractionEnabled = YES;

UITapGestureRecognizer *tapImageView = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapImageAction)];

[imgView addGestureRecognizer:tapImageView];

二、部分常用属性解析

1、设置本地图片（3种方式）

（1）第一种

[imageView setImage:[UIImage imageNamed:@"1.jpeg"]];

（2）第二种

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"timg" ofType:@"jpg"];

UIImage *images = [UIImage imageWithContentsOfFile:filePath];

[imgView setImage:images];

（3）第三种

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"timg" ofType:@"jpg"];

NSData *data=[NSData dataWithContentsOfFile:filePath];

UIImage *image2=[UIImage imageWithData:data];

[imgView setImage:image2];

2、设置网络图片

UIImage *urlImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1510311357723&di=5d10e3dca9da10b33a1cf3f2b7807b0f&imgtype=0&src=http%3A%2F%2Fpic7.photophoto.cn%2F20080529%2F0034034465128235_b.jpg"]]];

imgView.image = urlImage;

3、设置圆角

imgView.layer.masksToBounds=YES;

imgView.layer.cornerRadius=10;

4、设置边框颜色和大小

imgView.layer.borderColor= [UIColororangeColor].CGColor;

imgView.layer.borderWidth=2;

三、属性拓展

1、播放一系列图片

UIImage *image1 = [UIImage imageNamed:@"img1"];

UIImage *image2 = [UIImage imageNamed:@"img1"];

UIImage *image3 = [UIImage imageNamed:@"img1"];

NSArray *imagesArray = @[image1,image2,image3];

imgView.animationImages = imagesArray;

// 设定所有的图片在多少秒内播放完毕

imgView.animationDuration = [imagesArray count];

// 不重复播放多少遍，0表示无数遍

imgView.animationRepeatCount = 0;

// 开始播放

[imgView startAnimating];

2、相对位置关系
