我正在将 Google Analytics 与 ios 一起使用，并且我想在调用 viewDidAppear 后立即更新自定义变量的数量，这是我的代码。
for (int i = 0 ; i < [KeyArray count]; i++) {
error = nil;
if ([KeyArray objectAtIndex:i] == @"Carat") {
NSDictionary *caratDict = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
NSString *value = [NSString stringWithFormat:@"Carat From %@ to %@",[caratDict objectForKey:@"caratfrom"],[caratDict objectForKey:@"caratto"]];
NSLog(@"%@",value);
if (![[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Carat" value:value scope:kGANVisitorScope withError:&error]) {
NSLog(@"carat =%@",error);
}
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
[[GANTracker sharedTracker] dispatch];
}
else if ([KeyArray objectAtIndex:i] == @"Clarity") {
NSDictionary *caratDict = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
NSString *value = [NSString stringWithFormat:@"Clarity From %@ to %@",[caratDict objectForKey:@"clarityfrom"],[caratDict objectForKey:@"clarityto"]];
NSLog(@"%@",value);
[[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Clarity" value:value scope:kGANVisitorScope withError:&error];
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
}
else if ([KeyArray objectAtIndex:i] == @"Color") {
NSDictionary *caratDict = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
NSString *value = [NSString stringWithFormat:@"Color From %@ to %@",[caratDict objectForKey:@"colorfrom"],[caratDict objectForKey:@"colorto"]];
NSLog(@"%@",value);
[[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Color" value:value scope:kGANVisitorScope withError:&error];
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
}
else if ([KeyArray objectAtIndex:i] == @"Price") {
NSDictionary *caratDict = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
NSString *value = [NSString stringWithFormat:@"Price From %@ to %@",[caratDict objectForKey:@"pricefrom"],[caratDict objectForKey:@"priceto"]];
NSLog(@"%@",value);
[[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Price" value:value scope:kGANVisitorScope withError:&error];
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
}
else if ([KeyArray objectAtIndex:i] == @"Shape") {
NSArray *shapes = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
for (int i = 0; i<[shapes count]; i++) {
[[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Shape" value:[shapes objectAtIndex:i] scope:kGANVisitorScope withError:&error];
NSLog(@"%@",[shapes objectAtIndex:i]);
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
}
NSLog( @"%@",shapes);
}
else if ([KeyArray objectAtIndex:i] == @"Type") {
NSArray *types = [selectedDiamondsFilter objectForKey:[KeyArray objectAtIndex:i]];
for (int i = 0; i<[types count]; i++) {
NSLog(@"%@",[types objectAtIndex:i]);
[[GANTracker sharedTracker] setCustomVariableAtIndex:1 name:@"Type" value:[types objectAtIndex:i] scope:kGANVisitorScope withError:&error];
if(![[GANTracker sharedTracker] trackEvent:@"Diamond Sort" action:@"Sort selected" label:@"sort" value:-1 withError:nil]){
NSLog(@"Not able to track for Diamonds Section");
}
}
}
[[GANTracker sharedTracker] dispatch];
if (error != nil) {
NSLog(@"Custom Variable HAS ERROR");
}
NSLog(@"%@",selectedDiamondsFilter);
}
但问题是它有时会更新“类型”有时会更新“克拉”，有时会更新其他内容。
请帮助我在哪里犯错。
