I found this problem, which is very weird.
- (void)imageMove:(float)xx y:(NSInteger)yy
{
NSLog(@"xx=%f,----yy=%d",xx,yy);
}
when I call this function:
[self imageMove:50 y:50];
the log shows: xx=0.000000,—-yy=50
You’re confusing yourself somehow. When I try doing what you said, I get this:
Since that isn’t what you get, you must be doing something different from what you say you’re doing. For example, you might be calling
imageMovefrom somewhere else that you’ve forgotten about. Put a breakpoint on yourNSLogline and work your way back through the call stack to see what’s really happening. Also, that way you can see what valuexxactually has when it arrives as an argument.
