项目功能介绍:
在主控制器中实现的代码:

// XGCustomCamera

#import "XGMainViewController.h"
#import "XGCameraController.h"
@implementation XGMainViewController{
UIButton *_openCameraBtn;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self setupOpenCameraBtn];
}
-(void)setupOpenCameraBtn{
_openCameraBtn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 200, 150)];
_openCameraBtn.center = self.view.center;
[self.view addSubview:_openCameraBtn];
[_openCameraBtn setImage:[UIImage imageNamed:@"Camera"] forState:UIControlStateNormal];
[_openCameraBtn addTarget:self action:@selector(openCamera) forControlEvents:UIControlEventTouchUpInside];
}
-(void)openCamera{
XGCameraController *cameraVC = [XGCameraController new];
[self presentViewController:cameraVC animated:YES completion:nil];
}
@end
通过PopOVer的方式实现字体大小和颜色选择的相关代码:
-(void)xg_addChangeSignWithFontColor:(UIButton *)sender{
XGSwitchColorController *switchColor = [XGSwitchColorController new];
switchColor.xg_BgColor = ^(UIColor *cellColor){
_waterLable.textColor = cellColor;
_popSwitchFontColor = cellColor;
};
[self xg_setupPopViewWithAttribute:switchColor andView:sender];
}
-(void)xg_changeSignatureWithFontSize:(UIButton *)sender{
XGSwitchFontSizeController *switchSize = [XGSwitchFontSizeController new];
switchSize.xg_FontSize = ^(NSInteger fontSize){
_waterLable.font = [UIFont systemFontOfSize:fontSize];
textSize = fontSize;
};
[self xg_setupPopViewWithAttribute:switchSize andView:sender];
}
-(void)xg_setupPopViewWithAttribute:(UIViewController *)vc andView:(UIView *)view{
vc.modalPresentationStyle = UIModalPresentationPopover;
vc.preferredContentSize = CGSizeMake(60, 200);
vc.popoverPresentationController.delegate = self;
vc.popoverPresentationController.sourceView = view;
vc.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionDown;
CGSize size = view.bounds.size;
vc.popoverPresentationController.sourceRect = CGRectMake(size.width * 0.5, -5, 0, 0);
[self presentViewController:vc animated:YES completion:nil];
}
