Objective-C Learning Notes - UIImage(坑)

使用 UIImage 显示图片:(通过 UIImage 的方法 drawAtPoint 或者drawInRect)

麻痹又是一段不能用的代码!!!!!@20150211

#@import "UIKitPrjUIImage.h"
//实现 UIView 子类
@implementation DrawImageTest
- (id)initWithImage:(UIImage *)image{
    if ((self = [super init])){
        myImage = image;
    }
    return self;
}
- (void)drawRect:(CGRect)rect{
//    切换 drawAtPoint 与 drawInRect
    [myImage drawAtPoint:rect.origin];
//    [myImage drawInRect:rect];
}
- (void)viewDidLoad {
    [super viewDidLoad];
    //读入文件
    myImage = [UIImage imageNamed:@"0.jpg"];
    //创建定制的 View
    DrawImageTest *test = [[ViewController alloc]initWithImage:myImage];
    
    test.frame = self.view.bounds;
    test.autoresizingMask = UIViewAutoresizingFlexibleTopMargin|UIViewAutoresizingFlexibleBottomMargin;
    
    [self.view addSubview:test];
    // Do any additional setup after loading the view, typically from a nib.
}
