如何使用JSON

Question

解析5個陣列中的一個對象，我被困在這個問題中，JSON的輸出是

"forecast":[ 
{"day":"Today","condition":"MostlyClear","high_temperature":"94","low_temperature":"70"}, 
{"day":"Tomorrow","condition":"Sunny","high_temperature":"95","low_temperature":"69"}, 
{"day":"Saturday","condition":"Sunny","high_temperature":"94","low_temperature":"71"}, 
{"day":"Sunday","condition":"Sunny","high_temperature":"93","low_temperature":"70"}, 
{"day":"Monday","condition":"Sunny","high_temperature":"94","low_temperature":"70"} 
] 

我需要狀態鍵顯示在tableview中單元格的值。而我的代碼是

temp=[[NSString alloc] initWithData:[dataLoader httpData] encoding:NSUTF8StringEncoding]; 
NSLog(@"Patient Details %@",temp); 

array = [[temp JSONValue] objectForKey:@"forecast"]; 

NSDictionary* dic = [array objectAtIndex:[indexPath row]]; 
NSString *strDay = [dic objectForKey:@"day"]; 
NSString *stringCondition = [dic objectForKey:@"condition"]; 
NSLog(@"condition is %@", stringCondition); 
NSString *stringTemp = [dic objectForKey:@"high_temperature"]; 
NSString *stringLow = [dic objectForKey:@"low_temperature"]; 

但是它顯示只有一個條件值，我想所有這一切的時候5個條件。我也嘗試使用NSArray而不是NSString，因爲沒有運氣。

Answer 1

array = [[temp JSONValue] objectForKey:@"forecast"]; 

做一個for循環在這個地方：

for(NSUInteger index = 0; index<[array count]; index++) 
{ 

NSDictionary* dic = [array objectAtIndex:index]; 
NSString *strDay = [dic objectForKey:@"day"]; 
NSString *stringCondition = [dic objectForKey:@"condition"]; 
NSLog(@"condition is %@", stringCondition); 
NSString *stringTemp = [dic objectForKey:@"high_temperature"]; 
NSString *stringLow = [dic objectForKey:@"low_temperature"]; 
} 

希望這將有助於...
