UISegmentedControl - 最后段不容易选择

Question

所以我使用的是UISegmented所示的控制

最后一段“5”是非常努力，击中我的手指。我从模拟器使用游标注意到，只有大约一半的段会响应。任何一半的权利基本上是一个死区。我不确定是什么导致了这个问题，因为我已经将这个分段控件移到顶端，它仍然执行相同的操作。但是，如果我将分段控件移动到屏幕中心，则5段整个表面区域会响应触摸事件...

我不知道如何解决此问题。

要了解可能重叠的代码，添加此UIView的类别：

@interface UIView (Dumper_Private) 

+ (void)appendView:(UIView *)v toStr:(NSMutableString *)str; 

@end 

@implementation UIView (Dumper_Private) 

+ (void)appendView:(UIView *)a toStr:(NSMutableString *)str 
{ 
    [str appendFormat:@" %@: frame=%@ bounds=%@ layerFrame=%@ tag=%d userInteraction=%d alpha=%f hidden=%d\n", 
     NSStringFromClass([a class]), 
     NSStringFromCGRect(a.frame), 
     NSStringFromCGRect(a.bounds), 
     NSStringFromCGRect(a.layer.frame), 
     a.tag, 
     a.userInteractionEnabled, 
     a.alpha, 
     a.isHidden 
     ]; 
} 

@end 

@implementation UIView (Dumper) 

+ (void)dumpSuperviews:(UIView *)v msg:(NSString *)msg 
{ 
    NSMutableString *str = [NSMutableString stringWithCapacity:256]; 

    while(v) { 
     [self appendView:v toStr:str]; 
     v = v.superview; 
    } 
    [str appendString:@"\n"]; 

    NSLog(@"%@:\n%@", msg, str); 
} 

+ (void)dumpSubviews:(UIView *)v msg:(NSString *)msg 
{ 
    NSMutableString *str = [NSMutableString stringWithCapacity:256]; 

    if(v) [self appendView:v toStr:str]; 
    for(UIView *a in v.subviews) { 
     [self appendView:a toStr:str]; 
    } 
    [str appendString:@"\n"]; 

    NSLog(@"%@:\n%@", msg, str); 
} 

@end 

，并呼吁[UIView dumpSuperviews:theSegmentedControl];
