iOS学习笔记(三十五)————画图与通讯录

绘图

iOS中的绘图有很多种方式，我们这里简单说一下Core Graphics的画图

 UITouch *touch = [touches anyObject];
 // 移动的点
 CGPoint point = [touch locationInView:self.view];
 // 创建一个画板
 UIGraphicsBeginImageContext(CGSizeMake(320, 480));
 // 获取当前的画板
 CGContextRef context = UIGraphicsGetCurrentContext();
 [imageView drawRect:CGRectMake(0, 0, 320, 480)];
 // 设置画笔的颜色
 CGContextSetRGBStrokeColor(context, 1, 1, 1, 1);
 // 设置线条的宽度
 CGContextSetLineWidth(context, 10);
 // 设置线条样式
 CGContextSetLineCap(context, kCGLineCapRound);
 // 把画笔移到某一个点
 CGContextMoveToPoint(context, firstPoint.x, firstPoint.y);
 // 从开始点 到哪个点之间形成一条线
 CGContextAddLineToPoint(context, point.x, point.y);
 // 把描的路径画出来
 CGContextStrokePath(context);
 // 把刚才画的东西 形成一张图片
 UIImage *image =  UIGraphicsGetImageFromCurrentImageContext();
 imageView.image = image;

这就是一个获取手指移动轨迹的画图方式。

通讯录

在开发中我们难免会用到使用系统app信息，比如我们要使用通讯录，就用以下的方法

- (void)test{
//读取手机通讯录
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
    
    //获取应用的授权状态
    ABAuthorizationStatus authorizationStatus = ABAddressBookGetAuthorizationStatus();
    
    //判断授权状态
    switch (authorizationStatus){
        case kABAuthorizationStatusNotDetermined:{
            //用户还没有作出关于这个应用程序是否可以访问数据类的选择。
            ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
                NSLog(@"%d", granted);
            });
        }
            break;
            
        case kABAuthorizationStatusRestricted:{
            //应用没有被授权访问数据类。用户不能改变 例如家长控制
        }
            break;
            
        case kABAuthorizationStatusDenied:{
            //用户明确拒绝此应用程序访问数据。
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请在iPhone的设置->隐私->通讯录中开启授权" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"设置", nil];
            [alertView show];
        }
            break;
            
        case kABAuthorizationStatusAuthorized:{
            //已经授权
        }
            break;
            
        default:
            break;
    }
    
    // 释放通讯录对象
    CFRelease(addressBook);
    
}
