UISegmentedControlですべてのセグメントの色合いの順序が逆転しているのはなぜですか？どのようにそれを修正するには？

Question

私はシミュレータを実行すると、このコードでは何のインデックスが間違って見つけることができませんcuz異なる要素のすべての色が反転されますか？次のように

マイViewController3.hファイルは次のとおりです。ここ

#import <UIKit/UIKit.h> 

@interface ViewController3 : UIViewController 

@property (weak, nonatomic) IBOutlet UIImageView *image1; 
- (IBAction)segmentControl:(id)sender; 
@property (weak, nonatomic) IBOutlet UISegmentedControl *mysegment; 
@property (weak, nonatomic) IBOutlet UIView *colorToBeDisplayedInView; 



@end 

は私ViewController3.mです：

#import "ViewController3.h" 

@interface ViewController3() 
@property (strong, nonatomic) IBOutlet UIView *segments; 
@property (weak, nonatomic) IBOutlet UILabel *label; 

@end 

@implementation ViewController3 




- (void)viewDidLoad { 
[super viewDidLoad]; 
//creating textField programmatically 
// UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 200, 300, 20)]; 
// textField.borderStyle = UITextBorderStyleRoundedRect; 
// textField.font = [UIFont systemFontOfSize:15]; 
// textField.placeholder = @"enter text here"; 
// textField.autocorrectionType = UITextAutocorrectionTypeNo; 
// textField.keyboardType = UIKeyboardTypeDefault; 
// textField.returnKeyType = UIReturnKeyDone; 
// textField.clearButtonMode = UITextFieldViewModeWhileEditing; 
// textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; 
// [self.view addSubview:textField]; 

//setting tint color for segments 
[[_mysegment.subviews objectAtIndex:0] setTintColor:[UIColor redColor]]; 

[[_mysegment.subviews objectAtIndex:1] setTintColor:[UIColor blueColor]]; 

[[_mysegment.subviews objectAtIndex:2] setTintColor:[UIColor greenColor]]; 

[[_mysegment.subviews objectAtIndex:3] setTintColor:[UIColor purpleColor]]; 

[[_mysegment.subviews objectAtIndex:4] setTintColor:[UIColor orangeColor]]; 

//to preload everyview before hand 
_label.text=@"1"; 
_image1.image = [UIImage imageNamed:@"fruits.png"]; 
_colorToBeDisplayedInView.backgroundColor = [UIColor redColor]; 
} 

- (void)didReceiveMemoryWarning { 
[super didReceiveMemoryWarning]; 
// Dispose of any resources that can be recreated. 
} 

/* 
#pragma mark - Navigation 

// In a storyboard-based application, you will often want to do a little preparation before navigation 
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 
// Get the new view controller using [segue destinationViewController]. 
// Pass the selected object to the new view controller. 
} 
*/ 


- (IBAction)segmentControl:(id)sender { 
if (_mysegment.selectedSegmentIndex==0) 
{ 
    _label.text=@"1"; 
    _image1.image = [UIImage imageNamed:@"fruits.png"]; 
    _colorToBeDisplayedInView.backgroundColor = [UIColor redColor]; 
} 
else if (_mysegment.selectedSegmentIndex==1) 
{ 
    _label.text=@"2"; 
    _image1.image = [UIImage imageNamed:@"airplane.png"]; 
    _colorToBeDisplayedInView.backgroundColor = [UIColor blueColor]; 
} 
else if (_mysegment.selectedSegmentIndex==2) 
{ 
    _label.text=@"3"; 
    _image1.image = [UIImage imageNamed:@"boat.png"]; 
    _colorToBeDisplayedInView.backgroundColor = [UIColor greenColor]; 
} 
else if (_mysegment.selectedSegmentIndex==3) 
{ 
    _label.text=@"4"; 
    _image1.image = [UIImage imageNamed:@"arctichare.png"]; 
    _colorToBeDisplayedInView.backgroundColor = [UIColor purpleColor]; 
}else 
{ 
    _label.text=@"5"; 
    _image1.image = [UIImage imageNamed:@"cat.png"]; 
    _colorToBeDisplayedInView.backgroundColor = [UIColor orangeColor]; 
} 
} 
@end 

Answer 1

UISegmentedControlの最後のサブビューが

let x = UISegmentedControl(items: ["Red", "Green", "blue"]) 
x.subviews.last?.frame //(0, 0, 51, 29) 

Answer 2

NSString *value = [yourcolorsSegmentName titleForSegmentAtIndex:yourcolorsSegmentName.selectedSegmentIndex]; 
NSLog(@"%@", value); 
if ([value isEqualToString:@"Red"]) { 
//set tint color... 
} else if ([value isEqualToString:@"Green"]) { 
//set tint color... 
} 

左にあります

あなたのコードをこのように書くアプローチ.... これはあなたに完璧な出力を与えるでしょう....
