@synthesize a=b; 与@synthesize c;的区别
@synthesize a=b;
@synthesize c;

- (void)loadView {
a=1; ／／打印结果
b=9;
NSLog(@"loadView......%d",a); ／／结果 1
NSLog(@"loadView1......%d",b); 9
NSLog(@"loadView2........%d",[self a]); 9
NSLog(@"loadView......%d",a); 1

[self setC:5];

NSLog(@"loadView3......%d",c); 5
NSLog(@"loadView4........%d",[self c]); 5
}


个人觉得是引用。
