NSDictionary-SafeAccess

非常有助于IOS字典读写的轻量级扩展,Very useful safe accessors for NSDictionary,a lightweight NSDictionary access category

比如网络请求回来的JSON解析成字典后,数据的读取常常因为NULL而程序崩溃,有了SafeAccess

妈妈再也不用担心NULL啦

使用方法

读取 getter

NSDictionary *responseObject = /.......
NSDictionary *dic = [responseObject dictionaryForKey:@"object"];
NSArray *array = [responseObject arrayForKey:@"array"];
NSString *string = [responseObject stringForKey:@"string"];
long long date = [responseObject longLongForKey:@"date"];
NSNumber *number = [responseObject numberForKey:@"number"];
NSInteger count = [responseObject integerForKey:@"count"];
BOOL b = [responseObject boolForKey:@"count"]; 
CGPoint point = [responseObject pointForKey:@"point"]; 
CGFloat f = [responseObject CGFloatForKey:@"float"]; 
CGRect rect = [responseObject rectForKey:@"rect"]; 
CGSize size = [responseObject sizeForKey:@"size"]; 

写入 setter

NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObj:@"334" forKey:@"obj"];
[dict setString:@"string" forKey:@"str"];
[dict setBool:YES forKey:@"b"];
[dict setInt:1 forKey:@"intvalue"];
[dict setCGFloat:1.1 forKey:@"float"];
[dict setPoint:CGPointMake(1, 1) forKey:@"point"];
[dict setSize:CGSizeMake(111, 111) forKey:@"size"];
[dict setRect:CGRectMake(0, 0, 0, 0) forKey:@"rect"];
