iphone - 使用 DYRateView 的多个评分栏
<p><p>我有一个 View ，上面有 3 个评级栏。 </p>
<p>如何在代码中区分它们？现在，如果我更改最上面的一个，它会看到它很好，但是如果我随后更改其中一个或另外两个，它就无法将它们彼此分开。</p>
<p>代码来自 git <a href="https://github.com/dyang/DYRateView" rel="noreferrer noopener nofollow">https://github.com/dyang/DYRateView</a> </p>
<pre><code>- (void)changedToNewRate:(NSNumber *)rate {
NSString *rating = ;
NSLog(@"rating: %@",rating);
}
</code></pre>
<p>这是看到变化的地方。 </p>
<p>这是.m文件</p>
<pre><code>#import "Survey.h"
@implementation Survey
@synthesize btnSubmit;
- (void)setUpEditableRateView {
DYRateView *rateService = [ initWithFrame:CGRectMake(0, 55, self.view.bounds.size.width, 40) fullStar: emptyStar:];
rateService.padding = 20;
rateService.alignment = RateViewAlignmentCenter;
rateService.editable = YES;
rateService.delegate =self;
;
;
DYRateView *rateFood = [ initWithFrame:CGRectMake(0, 130, self.view.bounds.size.width, 40) fullStar: emptyStar:];
rateFood.padding = 20;
rateFood.alignment = RateViewAlignmentCenter;
rateFood.editable = YES;
rateFood.delegate = self;
;
;
DYRateView *rateCleanliness = [ initWithFrame:CGRectMake(0, 200, self.view.bounds.size.width, 40) fullStar: emptyStar:];
rateCleanliness.padding = 20;
rateCleanliness.alignment = RateViewAlignmentCenter;
rateCleanliness.editable = YES;
rateCleanliness.delegate = self;
;
;
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
;
return YES;
}
- (void)changedToNewRate:(NSNumber *)rate {
NSString *rating = ;
NSLog(@"rating: %@",rating);
}
- (IBAction)btnSubmit:(id)sender{
}
-(IBAction)mainMenu{
;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
;
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
;
;
;
scroller.BackgroundColor = ;
;
;
}
- (void)viewDidUnload
{
;
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end
</code></pre>
<p><strong>更新</strong></p>
<p>好的，我添加了一个 if 语句的新代码</p>
<pre><code>- (void)rateView:(DYRateView *)rateView changedToNewRate:(NSNumber *)rate {
NSString *barName = ;
if (barName == @"rateView1") {
NSString *bar1 = ;
NSLog(@"bar 1: %@",bar1);
}else if(barName == @"rateView2"){
NSString *bar2 = ;
NSLog(@"bar 2: %@",bar2);
}else{
NSLog(@"NO BAR: %@",barName);
}
self.rateLabel.text = ;
}
</code></pre>
<p>但是它可以工作，而不是返回“rateView1”或 2 或 3。我回来了 </p>
<pre><code> NO BAR: <DYRateView: 0x78229b0; frame = (0 40; 320 20); opaque = NO; layer =
<CALayer:0x7824900>>
</code></pre>
<p>这在本质上是正确的，但我希望使用 rateView 的名称，例如“rateView1”</p>
<p><strong>解决方案:</strong></p>
<p>在 .h 文件中@property 你的 2 或 3 根柱子</p>
<pre><code>@property(nonatomic, retain) DYRateView *rateView1,*rateView2;
</code></pre>
<p>在 .m 中 @synthesize 它们</p>
<pre><code>@synthesize rateView1;
@synthesize rateView2;
</code></pre>
<p>然后</p>
<pre><code>(void)setUpEditableRateView {
rateView1 = [ initWithFrame:CGRectMake(0, 40, self.view.bounds.size.width, 20) fullStar: emptyStar:];
rateView1.padding = 20;
rateView1.alignment = RateViewAlignmentCenter;
rateView1.editable = YES;
rateView1.delegate = self;
;
;
rateView2 = [ initWithFrame:CGRectMake(0, 100, self.view.bounds.size.width, 20) fullStar: emptyStar:];
rateView2.padding = 20;
rateView2.alignment = RateViewAlignmentCenter;
rateView2.editable = YES;
rateView2.delegate = self;
;
;
// Set up a label view to display rate
self.rateLabel = [[ initWithFrame:CGRectMake(0, 80, self.view.bounds.size.width, 20)] autorelease];
self.rateLabel.textAlignment = UITextAlignmentCenter;
self.rateLabel.text = @"Tap above to rate";
;
}
</code></pre>
<p>最后</p>
<pre><code>- (void)rateView:(DYRateView *)rateView changedToNewRate:(NSNumber *)rate {
if (rateView == rateView1) {
NSString *bar1 = ;
NSLog(@"bar 1: %@",bar1);
}else if(rateView == rateView2){
NSString *bar2 = ;
NSLog(@"bar 2: %@",bar2);
}else{
NSLog(@"NO BAR: %@",rateView);
}
self.rateLabel.text = ;
}
</code></pre></p>

<p><p>感谢您使用 DYRateView!</p>
<p>DYRateView 的当前版本不支持同时监听多个实例，但这并不意味着我们不能这样做。 :)</p>
<p>如果不介意更新源代码，可以在DYRateView.m中找到一个名为<code>notifyDelegate</code>的方法，将<code>]</code> 到类似 <code>]</code>。通过这种方式，您可以将 rateView 本身作为参数传递给它的监听器。 </p>
<p>我还没有尝试过上面的代码，因为此时我无法访问我的 Mac，但我认为这应该让您了解如何实现您的目标。 </p></p>
