OS X 有一个特有的控件叫做 IKPictureTaker，允许用户从计算机上选择一张图片，或者从摄像头捕捉一张图片。当用户选择了图片之后，这个控件会调用指定的代理方法。
系统图片选取
摄像头选取
实现效果图
1.API
-(void) beginPictureTakerSheetForWindow:(NSWindow *)aWindow withDelegate:(id) delegate didEndSelector:(SEL) didEndSelector contextInfo:(void *) contextInfo;
2.import
#import <Quartz/Quartz.h>
3.实现代码
[[IKPictureTaker pictureTaker] beginPictureTakerSheetForWindow:[NSApplication sharedApplication].keyWindow withDelegate:self didEndSelector:@selector(pictureTakerDidEnd:returnCode:contextInfo:) contextInfo:nil];
4.代理方法
- (void)pictureTakerDidEnd:(IKPictureTaker *)picker returnCode:(NSInteger)code contextInfo:(void*)contextInfo{
NSImage * image = [picker outputImage];
if (image) {
self.imageView.image = image;
}
NSLog(@"NSImage:%@",image);
NSLog(@"code:%ld",code);
}
