UIView의 하위 클래스 인 UIToolBar를 사용하여 클래스를 만들고 별도의 뷰 컨트롤러에서 인스턴스화 할 수 있습니다. 이 접근 방식은 실시간 피드백 (이 경우 AVCaptureSession에 대한)을 제공하는 반투명 UIToolBar (UIView에 의해 서브 클래 싱됨)를 보여줍니다.
YourUIView.h
#import <UIKit/UIKit.h>
@interface YourUIView : UIView
@property (nonatomic, strong) UIColor *blurTintColor;
@property (nonatomic, strong) UIToolbar *toolbar;
@end
YourUIView.m
#import "YourUIView.h"
@implementation YourUIView
- (instancetype)init
{
self = [super init];
if (self) {
[self setup];
}
return self;
}
- (void)setup {
// If we don't clip to bounds the toolbar draws a thin shadow on top
[self setClipsToBounds:YES];
if (![self toolbar]) {
[self setToolbar:[[UIToolbar alloc] initWithFrame:[self bounds]]];
[self.toolbar setTranslatesAutoresizingMaskIntoConstraints:NO];
[self insertSubview:[self toolbar] atIndex:0];
[self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[_toolbar]|"
options:0
metrics:0
views:NSDictionaryOfVariableBindings(_toolbar)]];
[self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[_toolbar]|"
options:0
metrics:0
views:NSDictionaryOfVariableBindings(_toolbar)]];
}
}

[self.toolbar setBarTintColor:blurTintColor];
}

위의 UIView가 사용자 정의되면 계속해서 ViewController의 하위 클래스 인 클래스를 만듭니다. 아래에서 AVCapture 세션을 사용하는 클래스를 만들었습니다. Apple의 내장 카메라 구성을 재정의하려면 AVCaptureSession을 사용해야합니다. 따라서 YourUIView 클래스 에서 평범한 UIToolBar를 오버레이 할 수 있습니다 .
