iOS開發 擷取狀態列的點擊事件

標籤：enabled   pyc   sse   default   div   with   copy   bsp   cti   

首先我們追蹤UIStatusBar的觸摸事件，需要在AppDelegate裡面加入以下代碼

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {    [super touchesBegan:touches withEvent:event];    CGPoint location = [[[event allTouches] anyObject] locationInView:self.window];    CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;    if (CGRectContainsPoint(statusBarFrame, location)) {        [self statusBarTouchedAction];    }}

然後在statusBarTouchedAction方法中將顯示在當前keyWindow裡面的scrollView滾動到頂部

- (void)statusBarTouchedAction {

      [[DDTopWindow defaultDDTopWindow] scrollsToTop];

}

下面來看JMSUIScrollViewTool

@interface DDTopWindow : UIView

 

+ (instancetype)defaultDDTopWindow;

 

- (void)configScrollView:(UIScrollView *)scrollView isCanTop:(BOOL)isCanTop;

 

- (void)scrollsToTop;

 

@end

 

#import "DDTopWindow.h"

 

static UIScrollView *scrollView_;

 

@interface DDTopWindow ()

 

@property (nonatomic, assign) BOOL isCan;

 

@end

 

@implementation DDTopWindow

 

SYNTHESIZE_SINGLETON_FOR_CLASS_ARC(DDTopWindow);

 

- (void)configScrollView:(UIScrollView *)scrollView isCanTop:(BOOL)isCanTop {

  scrollView_ = scrollView;

  self.isCan = isCanTop;

}

 

- (void)scrollsToTop {

  if (scrollView_.scrollEnabled) {

    [scrollView_ setContentOffset:CGPointMake(scrollView_.contentOffset.x, -scrollView_.contentInset.top) animated:YES];

  }

}

 

@end
